C2305 not switching on

[Gnair]

I bought this product online yesterday & used it just half a day & phew it went off. I tried switching it on back but in vain. It had updated to the latest build version via pc companion also. I have requested for  the replacement from the online retailer. Don't know how this happened.

Have you discharged the phone completely?Connect to wall charger,charge for 1-2 hours,turn it on.

I charged it full overnight but still in vain.

Force turn off the device:

After that,turn it on normally.

Ok the reset key on the back did wonders & switch the phone on. But now the screen of the phone keeps flickering. Also i had installed clean master will this app give any issues. The build number is 16.0.B.2.6.

Do not use task killers or battery savers,the default one is good enough.

What about the screen display flickering...

Gnair,

Disable Adapt Lightning Conditions in Display > Brightness. This will solve flickering issue!

About the screen flickering,really do not know.Have you tried a software repair until now?

I checked in the settings & just have Automatic brightness option. Didn't find the option mentioned by you.
