Android 3.x ??? It "crashes" easily due to buggy software. Just turn the thing off for 10 seconds or so and then turn it back on. Really, that's all you can do until Google fixes the bugs that caused the problem in the 1st place.~ PC-Doctor
Well it could be many things like bad outlet to bad charger but my best guess is the medal piece inside your charger is not touching the one in the tablet to charge it. Try replacing your charger if that don't work take it in your tablet to get fixed its most likely the one in the tablet. Thing wear down with use. I should know I just had mine fixed too! Good luck hope I helped.
I really need a bit more information. If this happens only on one particular game then did that game ever run correctly? If it did, then the problem has occurred since installation and could be fixed by clearing the cache. Look in settings and application management to find the button to press. While you are at it select to force close the app as well. Then restart. If the game has never worked correctly then the installation could have failed and you need to uninstall and start again.
You could also be advised to remove the game booster to see if it is interfering with your system.
If ALL your games are failing then I would remove the booster first and possibly reinstall the games as the booster changes the install state of the games and this may be an issue.
It is unlikely that this is a virus. Viruses generally have an ulterior motive and the coding to restart your machine via a virus would just not be worth while to a hacker.
Like I said at the beginning I really need more info. If none of this helps post a new problem and include as much information as possible about what has happened and what is happening now. That may encourage more people to help you. None of us likes flying blind trying to solve a problem just by saying try this or try that. It makes us sound so unprofessional.
Depends on the attachment. You might not have an app that is compatible with the document type you are trying to open. Assuming you are opening a PDF file, you might need to install an office suite app first, such as WPS Office or Quickoffice. Without more details, I can't be specific.
You can try to enter with your google account, but WiFi must be activated and you must be sure you are connected to the internet.
Next solution is to do a factory reset. This will erase all your personal data. If you have a backup, this is not a problem.
If your notes are on the SD card then take out the SD card and perform a 'Factory Reset' on the tablet. This will loose all saved data on the device so be careful. Replase the SD card and re download all your apps. The data on the SD card will not be effected.
Depending on your email client some folders are set as system folders, i.e. are required for the proper operation of the system, these cannot be deleted.
