Answer to: My phone keeps installing apps by it self, what to do?i had the same problem earlier and found the solution finally. this issue is there in most of the cheep chinese phones and tablets. these phones have pre installed trojan program which cannot be removed from the phone. i tried many applications including trojan remover and so on. No use... but finally i downloaded No root firewall application from google play store(https://play.google.com/store/apps/detai...). this application blocks all the events and unwanted programs including download manager which downloads unwanted programs without your concern. now i dont have issue. i allow the download manager whenever i want and other time i block download manager and other trojan suspected programs. this solution might help you.
