Hi my phone died for 2 days it just suddenly turned off while I’m playing Mobile legends then won’t turn on even after doing the home/power button hold, even charging it didn’t help. Now, it suddenly turned on after 2 days. The phone mysteriously turned on. Before it i had my phone checked up by a technician he opened the phone and said it will be hopeless to repair the phone but then the phone turned on after hours of checking the phone. Can anyone explain this?
