Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Customers like the screen, performance, speed and quality of the tablet. For example, they mention it's beautiful, crisp, has amazing graphics and works perfectly as a laptop replacement. That said, they say it'll download photos and videos quickly and that the Quad-Core processor is extremely fast and responsive. Customers are also impresseded with the quality, saying it'd be a great tablet to own.

Cons:1. Built on Android does not mean you can have Google Play Apps. This is an unfortunate inconvenience, as there are some Google Apps that are just better than their Amazon App counterparts, and a few that I can not find within the Amazon Apps. If you want a fully functional tablet, then buy a tablet and download the free kindle app. If you want to pay more for something that does less, then the kindle is for you. This was a gift, so I will keep it, and continue to use my phone for the rest of my Apps that are not available on the kindle.2. Camera is less than perfect. Limited settings available. Again, I will use my phone for pics, the same scene with my phone showed the flames, with a small amount of glare. (Husband is a firefighter, so I take a lot of pictures of their exercises for their training.) An old Casio Exilim C721 phone with 5MP camera still takes better pictures at night.3. Kindle unlimited... I can not find anything worthy of paying a subscription price every month for. The Authors I want to read are not included.4. Amazon Prime... See #3, They doubled the price, and to me I just don't see anything there worthy of the cost, including Amazon instant video, no shows that I watch are included. Another family member did the 30 day trial, and was quite disappointed when his content disappeared after the trial.5. Youtube videos work ok, sometimes choppy, could be my connection or the device (computer playback worked fine when I had the time to test simutaneously). Other online video from various sources would not play in Silk Browser, refer to #1 Chrome Browser not available to download.6. Office Suite... I can not figure out how to unlock documents. I can view them, but I can not edit them.Somewhere in the middle:1. Email is easy to read, but hard to organize. If using folders that automatically sort your incoming mail (Yahoo) those folders are unavailable.2. Battery Life, I am just not getting the advertised battery life out of my kindle. 4 hours of reading and the battery level drops to 15%. Two-Three hours of video and it is time to plug it in again. Not horrible, but not as expected either.3. The carousel drove my nuts, thanks for fixing it!4. Audio is acceptable, would be nice to have bass and treble adjustment. Good volume for your personal space, but too big to carry around with you if you are moving room to room doing chores.Pros:1. BIG beautiful screen, indoors and out2. Keyboard is easy to use, I considered a case with a bluetooth keyboard and discovered that it was not needed.3. Whispersync is awesome when the battery dies and I have to switch to my paperwhite or (again) my phone.Why I wanted the Kindle Fire... I am an EMT and the course for the next level is starting early next year, the book weighs a ton, and is 1550+ pages. There is a Kindle Edition of the book available, and I wanted the full features available of the ebook. The Kindle was a gift based on what I thought I wanted... Hindsight shows that I wanted and expected so much more.
I'm not by any means new to technology, but I am new to tablets and had been flirting with an iPad Mini. Amazon had a special for one day, whereupon I bought the 8.9HDX (3rd Gen) and IMHO, this thing dances swirls around the iPad Mini. Resolution, colors, crispness of images and sound, oh what a difference on sound. A fair bit of research that day was telling me that Amazon's tablets are, dollar for dollar, superior in hardware and features--this made possible, I'm sure, mainly because if you get a Fire, you're more likely to buy their apps, books, etc. That's been true, and it's more than fair. That said, I was worried that I would not be able to access competitors' websites (or at least it would be made difficult) because somewhere I'd read something along that line and that has not been the case, at all. There ARE some PlayStore apps that you can't install, either direct from them OR via sideloading and I don't know the extent of that yet; I've only run into it on a game so far. (Jury's out on that, in other words.)
But regarding apps. When I checked on Amazon's apps prior to ordering, I didn't see much! However when I went to the same app store through my Fire, whammo! There was a whole lot more there. I've found a lot of apps in categories such as "Productivity" and I'm thinking maybe the Amazon App store is underrated.
Apps aside, this Fire is doing far more than I ever thought it would. Especially great is the microphone on the virtual keyboard that I can use "speech-to-text" so I can dictate emails, website URLs, search terms -- anywhere you'd enter text, you can hit the microphone instead. It has EXCELLENT voice recognition software, even picking up on terms unique to spinning and knitting, slang, purposely mispronounced words such as "gotta" and "whatcha gonna do?" if you pronounce them clearly. It picks up on punctuation including "full caps yes exclamation point" will give you "YES!" In google searching for "Voice Recognition Commands" to see what else is there, I keep reading that Android Voice Recog. software seems lacking. That might be a big plus for the Amazon products. If so, it's an important feature to me because it saves soooo much time.
Youtube videos on this thing are far better than they even are on my laptop, which is excellent. I have yet to run into a buffer wait, and you can click on the full screen square on the video and that's another place where the very high resolution on the Fire wins the day.
Rear camera takes outstanding photos and videos. I mean, really good. I exported them off the tablet and onto my laptop and they are crisp, clear, very accurate colors, really good. The sound is beyond expectation. I noticed that right away but I'm super aware of it in youtube tutorial videos I call in that are often created by women in other countries with heavy accents. I was made particularly aware of the sound last night when I installed Netflix app and brought in an episode of Parenthood that I've seen on TV - I could hear background conversation more clearly than I could on TV. The 4th Gen (2014) has even better sound (I compared the two in an electronics store side by side) but that's simply gravy on already outstanding potatoes and I didn't find myself envious of the difference, and I'm prone to that.
And a word about Skype. I'm crossing my fingers, arms, legs and eyes on this one, because the reviews on the Skype app are horrible. I didn't expect to be able to Skype on it. The first try, I did have delayed sound, but it cleared itself after a minute an it was in synch. The second Skype call was to someone else and we had outstanding picture/sound quality and perfect synch. So I may have gotten lucky, but my Skype is working really well from what I can tell so far.
There is a bit of a learning curve, but Mayday is fast and convenient. I cannot rave about the 3 Mayday experiences I've had, however, because they were not able to answer my questions without transferring me to someone more experienced; but they're good for basic stuff and quick answers and I may have gotten newbies to the job. There's a minimalist, but adequate, tutorial and "owner's manual" (in quotes) if you hit the ? icon (help). See those. And why they don't make it more clear, I don't know, but a finger swipe from the left brings up that program's operating menu. A finger swipe from the top brings down the Fire's operating menu. Always. That's the way it is on everything. Just figuring out those two constants made everything else quicker to learn.
All in all, I'd buy it again without a 2nd thought. Definitely get into perspective the extra $50 or $100 for more storage because whatever you buy, you're gonna live with it. Cloud does save the day on that, but I'd really rather not have to think about how much I'm loading onto my device.
So, I love my new Fire HDX (64Gb, wifi only with ads), but all the positives have already been reviewed at length by others, so I will concentrate on what I have not yet seen discussed elsewhere in a lot of detail:
1) Display mirroring (with Miracast). I got the NETGEAR Push2TV Wireless Display HDMI Adapter - Miracast and WiDi (PTV3000) and finally managed to make it work, no thanks to Netgear who have just lost a customer. Well, not really since I never bought a Netgear product before and arguably I didn't this time either as I bought it refurbished, but still. Installation issues notwithstanding, after it started working, it was pretty amazing. I tested the Miracast functionality successfully with both my Win8 laptop and my Kindle Fire HDX. Yes, there is a very slight lag, but nothing major and I suspect the technology will only get better what with the rate of the firmware updates being pushed out by Netgear for this product, trying to keep up with their competition which I think will be fierce now that Amazon has put its weight behind the Miracast technology by doing away with the HDMI output port entirely in the Fire HDX models. Which means that if you are emotionally attached to using an HDMI cable to connect to your external screen or TV, or just do not want to put up with the potential pain in the neck the installation of the PTV3000 may turn out to be (though to be fair, some people had no trouble whatsoever?), you will want to stick with the HD models instead. If you are excited about Miracast and want a WiDi adapter for your TV, use some caution, because as my review of said item demonstrates, it can be a hassle to setup.
A cheaper alternative is the Tronsmart T1000 Mirror2TV Wireless Display HDMI Dongle which performance is unfortunately not as good as the PTV3000 (noticeable time delays and pixelation when mirroring and requires use of their free proprietary app, EZCast).
2) Customer service. I have never seen any company spend so much time and effort into ensuring customers were happy with their flagship product (the Kindles, I mean. When it comes to every other product and services, they are just as impersonal and crushing as you would expect). I have rarely -if ever- had to contact Amazon with any of my Kindle issues before, but I was forced to contact an Amazon representative three times since my HDX arrived and each rep was unbelievably polite, helpful (and downright nice! all three of them! What?) and went to extraordinary lengths to resolve my issues (minor hardware problems - I'll update this review upon final resolution).
[UPDATED: my issues were resolved very satisfactorily, all it took was the guts to call Amazon support in the first place... All the customer service reps I spoke with -all 6 of them by now!- were helpful, patient, reasonable and even technically competent!? I don't understand this minor miracle, but it's certainly no coincidence and I was very glad to be able to take advantage of it. This great level of customer support is available for all your Kindle issues, not just HDX models, by the way].
One of my calls was made while testing the Mayday feature and I was stunned by how amazingly good the concept and execution of this idea was! Kudos to Jeff Bezos, this new feature is brilliant and will gain him major customer loyalty, especially among the older set (this is not meant to be insulting as I am no spring chicken myself).
3) Accessories. This tablet is a thing of beauty and a joy forever, granted, but it is also a fingerprint magnet -especially its display which is a touch screen, of course- and the rubberized back, which was so convenient and comfortable in the 7" original Fire, seems to have become a sponge for natural skin oils with the 8.9" HDX model? Fingerprints are everywhere and stay obstinately attached to every surface, not just the display, and personally I never figured on wiping them off as a full-time occupation.
My solution? DecalGirl skins (check their website for a dazzling number of choices or why not, the original DIY look: DecalGirl Skin - 'Create Your Own'): no, I do not work for them, I just spend a lot of time and as little money as possible trying to get the right accessories for my Kindles. They are a tad expensive ($20), but they are unbelievably easy to apply, of superior quality, extremely durable, come in a huge variety of designs from colorfully eccentric to classically elegant and DecalGirl often offers up to 25% discounts on their website. They will keep your Kindle looking and feeling like new.
Note that most cases easily fit over these skins but remember that if you also want a screen protector (I did!), it should be applied before the skin is applied to the body of the Kindle (front and back). By the way, covering the front of the Kindle (the bezel around the screen) makes holding your Kindle a lot more comfortable... This is no ad for DecalGirl: if you prefer one of their competitors (for instance: MightySkins Protective Skin Decal Cover), do your research and go for it, I am merely pointing out that I believe getting a good quality skin for your HDX is more important than buying a case. Also a lot cheaper than an Origami case, Amazon's preferred solution which at $50+ is just too rich for my tastes (sorry, this bon mot was just too easy)!
Speaking of accessories, since I cannot recommend any one case wholeheartedly, I can at least recommend the Targus Mini Stand (AWE65US). It's surprisingly practical and elegant for a simple block of transparent acrylic! Designed for any smartphone or tablet up to 10", it's perfect if you like watching videos on your HDX from a desk or a table rather than balanced in your lap.
4) Downloading videos. The limitations mentioned in B. Tarbuck's review could be a problem for everyone who purchased the 64Gb model with the new downloading features in mind, which was my case... but a few months of heavy usage later, I can confirm that the points he raises are not necessarily a big deal.
- First, you'll want to keep in mind that not all Prime videos are available for download as licensing rights limit what Amazon offers and which videos are Prime and downloadable is liable to change without notice. - Second, there is indeed a 25 downloaded videos maximum at any given time which personally I find is acceptable, even though I would have preferred to have heard about it beforehand rather than discover it afterwards. - Third, the Viewing Period limitation (48 hours or so depending on the video) is a lot easier to swallow when you realize it only starts applying to videos once you start watching them.
So the Viewing Period limit is actually quite comparable to the Lending Library's limitations: you just need to remember that Prime Videos are not available for streaming while you are traveling outside the US which is why you need to download them to your Fire HDX before leaving the US. Or if you are an overseas customer: yes, this IS discrimination! Just kidding, it's due to the same licensing rights limits referred to above which Amazon negotiates with the content owners (Warner, Fox etc.) themselves, ie the same people who insist on different DVD regions etc.
[IMPORTANT: the 'Viewing period' limit actually applies only once you've STARTED watching a video. As long as you simply keep your downloaded videos on your Kindle Fire for later viewing without starting the playback of the file, the Viewing Period limit is irrelevant. Now, that's more like it! :) ]
Personally, I invested in the 64Gb model because I am often in the position of traveling overseas for months, with very little personal internet access. Let's not get into a discussion of what most hotels overseas -ahem UK, I am looking at you here, not that Italy or Germany or Japan have a leg to stand on either- think is 'free internet access' or the availability of English-speaking entertainment media outside the US. Can you believe that some countries expect you to understand their own non-English language to get your entertainment?! Just joking: English is not my native language... My point stands, however.
Therefore purchasing the 64Gb model may be worthwhile if you like to load up your Kindle with lots of videos in preparation for a long overseas trip: just remember that once you start watching a video, a fairly short Viewing Period time limit starts running - about 48 hours (more or less depending on the movie/show in question). This is similar to the time limit you run into when downloading Prime Videos to your PC or renting vs. purchasing movies from Amazon, by the way... Please also note that movies and TV shows take up a huge amount of space when downloaded from Amazon, even when you do not choose the HD version, compared to your own personal videos (ripped from your own DVDs, I mean) which usually take up no more than 1 or 2 Gb per movie. Plus, your own videos have no such intrinsic Viewing Period time limit and can be re-watched as often as you want, forever, just like the videos you actually purchase from Amazon.
Remember, if you are willing to actually pay money to purchase a video from Amazon, you can then download it to your device at any time (while you are in the US), and keep it on the hard disk of your Kindle Fire -and any other Kindle Fire you own, past and future- forever (or you can re-download it repeatedly). Which is what Amazon is hoping we'll do, in fact... That's the whole point of selling the Kindles at near cost, after all.
One more relevant item of information when it comes to choosing your Fire HDX hard disk size: the micro USB port is not OTG compatible, so you cannot simply use an OTG USB key (like this little beauty for instance: Patriot Stellar Series 64GB USB 3.0 OTG - PSF64GSTROTG) to easily increase the size of your Fire HDX hard disk. Oh well...
5) non-Amazon content and apps: let's just reiterate a few points which most official reviews I have seen rarely make.
- you can totally get non-Amazon apps from the Google Play store. Or any reputable website, as long as you are careful and do a bit/a lot of research first if you don't want to be sorry later. Download the .apk file (all Android apps are really files with an apk extension), then transfer it to the appropriate folder on your Kindle. Opening the apk file then installs the app on your Kindle Fire and the app will afterwards appear in your Fire's Apps section. It's that easy! This simple process is called sideloading and no, it's not difficult or complicated and does not require rooting and does not invalidate your warranty or anything: the internet is full of simple how-tos on the subject, just begging to be read. And Amazon is perfectly fine with your sideloading non-Amazon apps, especially free apps.
Obviously Amazon will not refer to it or explain how to do it and they will avoid even mentioning it, but Jeff Bezos is well aware that lack of flexibility on this issue would be a deal breaker, even if he'd rather not admit as much officially. Which is why it's a fairly straightforward process, even though it would have been quite easy for Amazon to prevent us from sideloading non-Amazon apps.
- you can easily get non-Amazon ebooks (pdf or epub or any other commonly used ebook format, free or otherwise - B&N etc.) to your Kindle: just install the Calibre software on your computer and it will handle all the format converting and transferring to your Kindles, from the oldest Kindle e-reader to the latest HDX. Plus lots of other neat and amazing features, including tagging or helping with the rental of ebooks from your public library system. Calibre is free, it's got heaps of documentation and technical help, it's regularly updated and it can and will handle your whole ebook collection beautifully while synchronizing all your e-Readers easily. It's like iTunes for ebooks! If iTunes was easy to use, efficient, inclusive of formats and platforms. And came with helpful free add-ins like Firefox does. And did not lose your full media library the way iTunes loses mine all the time.
- comic books/graphic novels/mangas and magazines in pdf format. This is a seldom mentioned advantage of the 8.9" HDX: its larger screen size and higher resolution makes it a great way to read comics in pdf format with the built-in pdf reader! It's a bit less practical in cbr or cbz format (as opposed to reading comics on a PC where using a free cbr/cbz reader is best), but easily doable and well worth it for facing the hours of tedium that travel often requires. No need to use a comic book reader app, especially since the best such apps are not free, if your comics are in pdf format! But if your non-pdf comics library is just too extensive to convert, then you can check out ComiCat which costs $2.99: it handles most comic formats, organizes your collection nicely on your Kindle HDX and allows easy synchronization with cloud services like Dropbox, which is pretty nifty - compared to having to copy your comics files to your HDX yourself.
- other external content (music, photos, audiobooks and videos): nothing is to stop you from ripping your favorite DVDs and CDs (reliable free and paying tools are all around you) and transferring them to your Kindle Fire. It's even easier with an HDX than ever before!
I've been doing all of the above since the Kindle Fire 1st gen all the way to the HDX without any trouble via the USB port of my computer: a simple USB to micro USB cable -the same type of cable you use to recharge your Kindle- and you're all set! Or send your ebooks attached to an email to your Kindle's email address: Amazon Help pages are full of detailed descriptions about it... this email method incidentally lets you share your non-DRM ebooks with your friends and family simply by emailing them with your ebook. Assuming their own Kindles have been set up to accept documents from your email address - this last requirement is a security measure to avoid spam. Personally, I use this nifty 'sending books via email to a Kindle device' functionality to guilt my relatives into reading edifying books I think they would benefit from (passive-aggressive stuff about healthy diet, exercise and the like... ) and it helps with their insomnia issues, if nothing else!
Google will lead you to numerous helpful how-tos explaining which folder you should copy your video/audio files to on your Kindle Fire and which free apps to use if for some reason you do not want/cannot use the default app. Videos and Photos will show up in your gallery under your Photos section and your uploaded music and audiobooks, naturally enough, in your Music section. If your files are in a format your Kindle Fire cannot open and you don't want the headache of having to convert your files, just use one of several apps that open most files: personally, I use ES File Explorer to navigate the hard disk of my Fire and open all my non-Amazon content. You can also check out MoboPlayer which plays any video file format, not just only mp4 files like the Fire default video viewer app. These two apps are both available free on the Amazon app store and are very popular for good reasons.
Again: all of the above in point 5 works for all Fire models, not just the HDX.
6) On a different, UNRELATED topic: if for some reason you want to root your Amazon Fire in order to run the non-Amazon version of Android and be able to control the look and feel and functionality of your tablet, please be aware that you will lose all Prime membership advantages on this Fire tablet (though not on your computer or any other Fire you may own). Such as free Instant Prime Videos and the Lending Library. And Mayday functionality, also a bonus of the FireOS.
I just want to emphasize the fact that sideloading has nothing to do with rooting: the amount of ignorance and misinformation floating about this topic is simply astonishing. And by the way, I really don't recommend rooting a Kindle Fire, though yes, technically speaking, it is doable. By anyone with nerves of steel. And at least several hours of free, preferably uninterrupted time for in-depth research beforehand... Just be prepared to take responsibility for the waste of hundreds of your dollars if you do brick your Kindle device.
