I use "perfect piano" App, when I play on keyboard I hear many tones on one key.
That happened after update new version.

and also there is error in Bluetooth icon in bar at top. when I open that, the phone lagged and locked screen.

Contact the app developer regarding that issue as they have to fix this bug.

Do you experience the same lag while booting on safe mode?

How to boot on safe mode on Lolipop
1. press and hold the power key
2. once you get the pop up menu 
3. press and hold "power off" 
4. Boot on safe mode should become available

[Ahmed-Elwakeel]

Yes I still have these errors in safe mode. 

I tested Bluetooth only.

Other applications not found at safe mode. 

[Ahmed-Elwakeel]

I think this issue at new version not at application, because I tested all applications like that at play store.

It's not up to Sony to address this third party app issues, it's up to the app developer
