Z3+ Dual hang on standby mode

[abdielbk]

I just bought Xperia Z3+ Dual 5 days ago and has a lot of problems.

Battery draining so fast, always hang after 2-3 hours in standby mode and need to hard reset to switch on the phone again (press power button and volume up iin the same time).

Please help to solve the problem.

What do you mean by "I need to hard reset to turn the phone on"

I tried already only using standard application from factory but the problem still the same.

But the frequent of hang more increase when I download and used Theme from Sony Xperia.

Hard Reset that's mean press power button together with volume up in the same times until the phone vibrate 3 times.

I think doing a System Repair will solve any problems with the software .

Download PC Companion on Windows ,

Connect your device to your PC 

Then on the top left corner it should say Tablet/Phone update or something like that

Then in blue writing system repair

then follow the steps on the program

Remember to do a backup of your Photos and films , the app's data will not be saved tho!
