I have bought the Hisense Sero 7 Lite from Walmart last September to replace my broken cheap Android that was bought from Big Lots the year before. During my first three months of use, the tablet worked flawlessly, until around Christmas when after 25 minutes of usage, the unit locks up and turns itself off. At that time, I really thought it was the Live Wallpaper that is causing the unit to shut down without warning. Then, things got worse a few months later when after 10 minutes of usage, same thing happened. Then weeks later, after only five minutes, same result. Then starting last month, as I turned on the unit, the Hisense logo came on for a few seconds, followed by Hisense's SMART logo, and then after few seconds, it shuts itself off. Few minutes later, turned it on again, nothing happened.
But, after a few minutes, turned on the tablet, two Hisense related logos appear, and it went to the screen with date and time, and battery status. After logging in, I happened to load up an app(let's say TuneIn radio, for example), and the app appears. But after a few seconds, the unit locks up and it shuts itself off automatically. The next time I made another attempt to turn the thing on, only the Hisense logo appear for a couple seconds, then the unit just turns off. This problem even occurs while the tablet is charging. When you see the screen flickers and a soft "tick" noise while the unit turns off, this was the result.
I have tried everything(i.e. soft reset, factory restore, etc.) and the problem doesn't seem to go away. I am very frustrated by this now that the Sero 7 is my second tablet I have owned and it only last a very few months! I can't use apps. I can't play Candy Crush. I can't even watch Youtube videos in a public place using Wifi. I am going to send the unit to Hisense for repairs and possible replacement and I DO NOT want to spend even around $100 to purchase another tablet that will guarantee it's going to last only a few months. If this problem doesn't get solved, then I will never, EVER buy another HiSense product again!
I have uploaded a YouTube video of my attempts at booting up the Sero 7.
Once again, if there is no way to fix this problem, then this tablet is nothing but a WASTE OF MONEY!
