  1. my usus zenfone c start up is taking too long and not switching on at all, and its charging very slow. the only way i can switch on and use is when i hard reset it every time. once the phone shuts off it becomes like this. Any solutions?

    • Hi, please do not install too many apps after finish hard reset, because sometime same problems will happen when you install too many apps. You also may try to use different Google account to prevent cloud backup restore from previous Google account.
