TECLAST X98 Air 3G DUAL OS Android 5/Windows 10, 9.7" Retina Screen, 2GB/64 GB, Intel Z3735F Quad core CPU Tablet Phone FREE Screen Protector + Office Professional Plus

The title pretty much says it all, except (there is always an `except'!) the dual boot window is in Chinese (but easy to work out), and you get no UK manual or pretty much any instructions at all. If you can handle that, then this is an excellent laptop replacement for web browsing, email, games, videos, e-reading and cbr reading, and authoring on-the-go.Dual boot into Windows or Android, can be used as a hands-free phone (or more usually, you will be putting in a phone SIM so you get mobile internet), 64GB of internal storage (albeit shared by the two O/S), plus an SD slot allowing you to add more (mine has a 64GB SD card in it, which costs peanuts now). It's also fast and reliable - I've had mine over a month of solid use and never any issues after initial setup.Let's get straight down to the crux of the matter: there was a time when cheap imported tablet clones were underpowered and a compromise over the original. That time has gone with the Teclast. What I have is an IPad Air 2 clone with better basic specs, that boots into full Windows 8.1 or Android 4.4.4 (and which will soon migrate to Windows 10 and DirectX12 for free), with Office 365 thrown in for a year on top, all for less than half the price... if you want the price of the competing IPad, look to the 128GB Air 2, and come back when you have picked yourself from the floor.The only reason you would not chose the Teclast over the iPad is because you like labels or iOS, or are put off by the initial setup (i.e. you are a computer novice and prefer something that works 100% out-the-box and are prepared to pay for this). All good either way, but I can say I love my Teclast... perhaps not with the same passion as some of My Apple junkie friends, but hey, I've also got money to spend left over!In terms of accessories, if you look on a certain large Oriental Amazon clone, you will see that a nice Bluetooth keyboard case for this model is already available, giving you a small but full featured retina PC plus dual boot into Android. I own said case and its great: I actually use the Teclast with its Bluetooth keyboard case as a JavaScript web development environment. I'm writing a large JS/SVG web application using D3, Typescript and React/Flux as my front end stack... and the Teclast is my out-of-office go anywhere work machine. (my work desktop machine is a nice laptop, but a little heavy and too much for the train).I am also using my Windows O/S to run a full Windows version of Calibre library and MS Office365, and my Android portion to run Comicat. Both work perfectly, and the screen is beautiful for use as a document viewer. It also runs all Android games well, and many Windows casual games (and some of the less intensive full Windows games from a few years ago).NB - I use Novo Launcher on the Android portion, speeds it up considerably.NB2 - Although this is a very fast Android machine, Antutu rates it (and most retina screens) slightly unfairly - Antutu makes no concession for high resolution screens so retina tablets always score low for games despite their graphics muscle. However, its worth noting that Retina screens are not your best bet for games in any case. If you want a games machine, choose a lower resolution native screen.That's the main review over, the rest of this review answers all the usual buyer questions...Yes the tablet design is a rip-off of a competing Apple tablet. Amazingly, it is as thin and as light as the Apple version and the screen is identical (no really, it's the same LG screen), so it is actually a very very good copy. Only real difference I can see is that the Teclast scratches a little easier on the back... and it's far cheaper, and runs not one but two decent operating systems, so two up on the iPad Air!I have no idea what the iPad battery capacity is, but the Teclast is 8500MaH and its good for 5 hours of normal use (about 3 hours for intensive games).Yes, the wifi and mobile signal are both very good, and yes, it has excellent GPS. There are no cheap components here!Yes you do get a full legit version of Windows 8.1. This is a full windows tablet PC. If you add a keyboard, you have a full Windows 8.1 machine (see below for clarification on 32 vs 64 bit)).Yes, when you are windows, the screen refresh is 60Hz, not 30hz as in previous models.Yes, you get Play Store.Yes, it can be updated to windows 10, although on mine I had to force the update window to show up. Google is your friend.Yes you do get a one year subscription of Office 365. The icon is in Chinese but click on it and it comes up in English (and installs English), so all good.Yes the cpu is 64bit, and no, the O/S is not. Looking on the forums, it appears that the hardware may well be 64 bit ready, but the available drivers are 32 bit. I expect this to sort itself out in time. XDA forums are the ones to watch.Yes you can make phone calls from Android if you have a SIM card inserted, because it does have a phone mic. You have to set it for hands free for it to work. No you can't make a phone call from Windows, but you can use your SIM's mobile internet, which is even better - you can just use something like Skype for free for your calls (for bragging rights, and assuming you know how to set this up, it does have a forward facing camera so you get video calls not just phone calls!).To switch between Android and Windows, shut the laptop down, then when you restart it, click and hold the power button for about 5 seconds (and not the power and volume button as some sources tell you). You will see an Android and Windows symbol and a button with Chinese on it. Click the required symbol (windows or Android) then the Chinese button and it will boot in the chosen O/S. You do not see this option if you hold the power button for less than 5 seconds (it then boots into the last known OS and the boot switch option does not appear).No, the bluetooth is not multiport, so you can only have one Bluetooth keyboard or one Bluetooth mouse attached, not both. You have to have one or the other wired. Yes, the tablet does come with a micro-USB to USB connector (at least, mine did) so this is not actually a problem.The camera is awful. Don't buy this tablet if this is important to you. The sound, however is very good for a tablet. Loud and very clear.Yes, some of the Windows Metro apps are in Chinese when you first boot. Although the OS may have been set to UK English for you, Metro Apps do not update until you use them at least once with the internet on. Click on each one once to fire it up, and it will change to English (or you can set an English source in the App settings).Yes, the Android portion is very easy to root. There is a very long but very informative post on the TecLast on xda. Google is your friend, although you will also need a PC to host the Windows application that does the root.If you are buying your tablet cover/keyboard from that certain Oriental Amazon Clone because Amazon does not stock it yet but are wary of doing so, go to the Teclast fb page for the official Teclast shop link. (I've bought accessories direct from Teclast this way, no probs).No I have not tried to overclock it. The CPU already has a large peak overclock built in (2.8Ghz quad core off the top of my head, which is what used to pass for top end on desktops not so long ago!). I have run it in with Prime 95 and mine can actually hold the peak overclock stable without overheat (it does get warm though because the back plate is used as a heatsink, and it eats battery in this state, to be expected).Bad points?There is a bug in windows mode whereby the tablet never goes into a deep enough wait state if you let Windows sleep, meaning that your tablet drains within a day. If you want to come out of Windows, you should select shutdown and not let it sleep. This issue does not happen with the Android OS, so it's a driver issue and probably fixable.You don't get any UK instructions so have to have a little bit of knowledge and ability to set things up to your liking. It's not that difficult though because everything more or less works.Although The CPU is good enough to run windows 8.1 well, two things may slow you down. Firstly, you only have 2GB of RAM (DDR3 so pretty fast though), so don't have too many applications open at once. As long as you don't go mad, this is not an issue. The second thing is the hard drive: it's an eMMC not a SSD which means it is very fast for read but very slow for write. The eMMC is fine for most things I throw at it (word document writing, some JavaScript coding and testing, and general web browsing and email).When you first boot into windows, you will have a lot of updates it asks you to make. DO NOT MAKE THEM ALL AT ONCE! For some reason, this puts the tablet into a massive loop where it tries to install lots of updates, fails and then rolls back some of them. It takes it hours to get through it. Instead, check 10 at a time and do the updates slowly. After the initial big update, windows behaves. I have no reason why this happens, but suspect it is down to the large sustained disk write plus slow write of the eMMC causing windows update to time out and roll back in error.No windows key in windows mode.Conclusion.If you want the best cheap tablet, ebook reader, hands free phone and (if you get the keyboard case) windows laptop replacement, then get this tablet.You do however need to do about 20-30 minutes of work when you first get this tablet, because it is a Chinese device with the only concession being the locale set to the UK and language set to English... and it comes with no instructions.If that scares you, you probably need to pass and pay a little more, but be aware that you will be paying more for a less capable Apple or other `name' device. Get through the pain and you have a very capable, cheap and good looking device.Bargain for the bold![Edit] I should note that my seller was 'Digital Playworld'. They appeared to have done the initial work on changing the tablet over to English (changed language to 'EN' in both Windows and Android, but not the locale and not the source on certain Metro news/business feed apps). It took me about 10 minutes to complete the conversion, and my tablet is now 100% UK English throughout for Windows, and the same for Android (albeit with about 3 disabled Chinese apps in Android that don't uninstall). You may want to ask your seller if they will provide the same service (noting that your tablet will probably come unsealed if they do this because they have to power it up). I should also note that I would consider myself an advanced user (when I am not writing long geeky Amazon reviews I am gainfully employed as a senior web application developer), but I would consider getting the tablet over to full UK trivial for an average computer user.... just don't buy this tablet for a complete novice![Edit October 2015]: the Windows Sleep issue is fixed in the 2.02 firmware. I got mine from XDA. The firmware installer says something about losing your windows key but that didnt seem to happen (probably the author just covering themself!). I am running Windows 10.

No English manual at all, no guarantee card, some of the apps are still Chinese This product is for Chinese market not suitable for U.K market.
