I brought my Lenovo tab around 2 weeks ago and since having it I keep getting messages saying laucher3 has stopped. I read online to clear cache but it keeps coming up and I have to hard reset. also at any point playing games or on any apps a system message comes up saying reboot required and a count down for 2 seconds. When it reboots it goes into a start up loop and hard reset required again.
It seemed your OS isn’t, you need to full flash your Device, First, Backup your data and download https://firmwarefile.com/lenovo-a10-70f and flash your Tab, as this indicates A10-70F make sure it’s the same as your, ‘cause this is what I get, and try at your own risk, goodluck
