JXD S7800B Tablet HD Rockchip 3188 IPS LCD Capacitive TouchScreen ROM 16Gb Game Console Unlock Rooted Android 4 Free Retrogaming

unbelievable that this cost me £125! excellent build quality and screen is really sharp. i put in a 8gb sd card (cost about £10) and have stored 100's of snes , megadrive , ps1 and n64 games- all of which run perfectly. downloading the emulators and Roms is really easy (even for a technophobe like me !). Battery life is good - i can get about 6 -7 hours gaming on a charge. I only use it for gaming but it is far better value than 3ds and vita etc. very surprised at the build quality as we here all these bad things about china. It really looks and feels like a premium product

Rewritten 20/11/2014 and revised on 5/12/2014, originally one star but increasing to three. I hoped this would be the one portable device for retro-gaming that wasn't fundamentally flawed in some way; took a punt based on the number of reviews that said how awesome this thing was. I was a bit shocked to find the device's refresh rate was 66 Hz (rather than 60 Hz) meaning all of the emulators had vsync issues (really choppy scrolling in other words, Sonic the Hedgehog isn't so smooth when the game can't keep up with the screen). I wrote my original negative review based on this, but have since discovered it is a kernel bug in more recent versions of the device's firmware (my device shipped with S7800-01-V1.5-20140605.111625) and supposedly fixable. However, my device also has the following major issues: * Seems incompatible with my Virgin Media Super Hub wifi router. Data rate is incredibly slow and seems to impact other wireless devices. I have never had a single wifi problem with any other device on this network. Some users have reported dodgy soldering on the wifi antenna as the cause. * Stalls when downloading / installing apps from Google Play store. This renders the device unable to perform any transactions via Google Play until it is power-cycled. This is not connected with the wifi problem, but can occur simultaneously. Update: this appears to be caused by the updated Gmail app, which doesn't appear to work with the device. Uninstalling the update and de-selecting the automatic update option seems to fix this. * Charging is via the (supplied) A/C adaptor and not USB. I like the convenience of Android devices all using the same charger, so this is a shame. * No Bluetooth. I intended to return the device but as it was shipped from China, it would cost me a fair chunk of what I paid for it in postage. I decided to keep it and experiment with other firmwares, managing to flash it with an older revision. This fixed the refresh rate but introduced a new bug, where the device does a hard reset when you flick the power button once (i.e. to turn off the screen). Update: this is because my device is a 2014 model and older firmwares are not 100% compatible, introducing this bug. Flashing with the original V1.5-20140605.111625 firmware and applying the following kernel patch (Google "s7800 lujji kernel only" to find this) fixed everything apart from the wifi: 3.0.36+ lujji@linux-server #7 Tue Oct 21 04:21:53 FET 2014 With the 60 Hz refresh rate the emulators run beautifully as expected. The controller is very nice to use and the overall retro-gaming experience is about as good as I could have hoped for. In the future, I hope JXD might release a firmware update that fixes everything without having to use non-standard flash tools and hacked kernels. If I could fix the wifi problem it would be worth four stars; would be five but I have already spent a fair bit of time flashing and re-flashing the device before I had a tablet that was worth keeping. I can see why some users gave it five stars; theirs probably worked perfectly out-of-the-box. Its low cost might excuse some of its lack of refinement and with the 66 Hz bug fixed it makes an amazing handheld console.

If you are the kind of person who expects perfection, then this device is probably not for you. After a bit of research, I was a bit worried about quality issues but the temptation of being able to play retro games on a 7in screen made me take the plunge and order one of these intriguing bits of kit. I opted for the free delivery option and was pleased that the package arrived on the third day after I placed the order. The tablet itself is not bad in terms of build quality. Mine exhibits a little bit of flex from the back cover making a slight creaking sound, but I have had big name mobiles which were worse. The only real issue. I have is an occasional buzz from the left speaker, but this is intermittent and doesn't last for more than a minute or so. My research revealed that many buyers were worried about the quality of the charger which is unconveniently, not micro usb. When charging mine, I carefully monitored progress and the charger only got very slightly warm. It did take a few hours to fully charge though. Display quality is great. Only a couple of games are pre-loaded. The vast array of games apparently available when you launch the weirdly named "Happy Chick" app, are merely links to the manufacturer's web site, but selecting the link is straightforward and downloading is simply a case of tapping the confirmation button. Downloads did seem a bit slow though. The only emulators I have tried so far are the PSP, GBC and GBA emus. The PSP is a bit disappointing with choppy framerates and poor audio. The GBA and GBC emulators work brilliantly. Just watch out for which version you select as navigating menus in Japanese is near impossible unless you know the language. Overall I am happy with my purchase, so far, but I feel that if someone like Asus or Samsung built an equivalent device (i.e. full physical game controls) for £200 or so, I would buy one in a heartbeat.

After a three week wait it finally arrived. I was excited to see what all the fuss was about. This thing really has the potential to be incredible value for money and generally the reviews are positive. Problem is the build quality is obviously very hit and miss. I got a bad one unfortunately. I left the device charging for approx eight hours before I turned it on and the battery indicator was full. First thing i wanted to test was GTA San Andreas. This brings me onto my first niggle. It took all night to download the game. Thats insane. My phone does it in less than a minute. The wifi on this thing is appalling. Its so bad you can barely search the web and forget about watching youtube. Once downloaded, the game was running beautifully on max settings and I was really impressed. Very quickly things went downhill. Within 20 minutes the back of the device was extremely hot, within 25 minutes the screen starts flashing and then the device turns off with a dead battery requiring a full recharge. Gutted. Once recharged I tried again using the lowest settings. Same thing. So I tried less demanding games. Same thing. Then I tried a factory reset. Same thing. So basically it's a gamble with £100 of you hard earned cash. Alot of people rave about theirs so there must be good ones but how do you know it will be good for any length of time. Im not going to wait another three weeks to see if my next one is any good. Not worth the hassle. Ill spend my cash elsewhere. Maybe an nvidia shield tablet. Hope this helps.

Great piece of IT especially if you are like me and into retro gaming. Graphics are smooth, and sound is crisp. Very nice.

was working ok for 12 months or so then suddenly stopped working and nothing i can do now apart buy a new model )

Well, What a let down! Sluggish, Awkward lay out of file system, Poor battery, Struggles to play emulators past snes/megadrive. The list goes on, Brought for £112, Sold for £60 3 months later! I got an Nvidia Shield to replace it and that's great!!!!

Sadly mine arrived broken (screen popped out!), but as a cheap gaming machine, if you get one that works, it's pretty great. Clever control mapping and superb support for emulators.

Primera vez que puedo estar contento con un gran GamePad como este. He probado antes otras marcas y siempre era lo mismo, fallos de I+D (baterias mala calidad, pads incomodos, pantallas espantosas,etc). Sorprende la calidad del material y las especificaciones técnicas se acercan ya a los PCs que usamos. La revisión s7800 B nos viene con un procesador Quad core A9 a 1,6 GHz y 2Gb de RAM! Los pads analógicos son muy comodos y ayuda a recrearse uno mismo con los juegos de antaño, gracias al potencial de los emuladores en Android. Gran compra. Recomendable 100%

Mala decision adquirir este producto.Al menos en esta tienda. La consola me vino abierta (y hablo de la consola,no del empaquetado) por una esquina,con dos botones perdidos por dentro de la consola,que tuve que sacar y poner yo en su sitio.Parecia como si a alguien se le hubiera caido al suelo. Y dudo que haya sido algun transportista porque con el paquete cerrado y enbalado no creo que la consola sufriera de esa manera.Da la sensacion de que la han metido asi en la caja. Ademas,tiene un rendimiento muy pobre para la supuesta potencia que tiene.Un quad core a 1.8? No se lo creen ni ellos. Ademas pasandole el antutu me sale que esta capada a 1,4. Juegos como real racing 3 o san andreas van mucho mejor en un movil xiaomi rr 1s,que si tiene un quad core a 1,6 reales. 17500 puntos da en antutu frente a los 21500 del Red rice y con el epic citadel no pasa de 41 fps frente a los 60 del movil Ademas lo normal es encontrarla rondando los 140 euros y a mi me cobraron mas de 170. Por no hablar del mal ensamblaje del producto. Ya sabemos que es una consola "chinorris" y no se le puede pedir un acabado de ps vita. Pero al margen de que sea toda de plastico,cruje por todos lados. Da igual de donde la cojas porque suena todo a desencajado. No se si todo esto sera cosa del aparato en si o del que me han mandado ellos en particular. Pero no es lo que esperaba ni por asomo.

Es la única pega. El tiempo de entrega a sido de casi un mes por lo demás bíen aunque el adaptador de corriente a clavija europea no encaja bien en los enchufes por su forma cuadrada en vez de redona

Es una tablet/consola de juegos que va muy bien, muy rápida y con buenos gráficos, se puede recomendar a quien necesite una consola de juegos, además el envío de este vendedor ha sido mas rápido de lo que me esperaba, 3 días..

Me ha durado 3 meses pues la clavija de corriente se. Ha estropeado y ademas la sensibilidad de la pantalla deja mucho que desear
