System is not responding

[Sony000]

Every few minute the system freeze and a message appear (system is not responding. :close app or wait)

Restarting the phone doesn't solve the problem

What can I do?

@Sony000does the same thing happen in safe mode?

Hi @Sony000,

I'm sorry to hear this. As @najodleglejszy  suggested you should try to reboot your device to safe mode and see if you are still experiencing the same behavior.

I would also recommend that you temporarily remove any SD card you may have in your device to see if it may be causing this behavior. If there is no change I recommend that you perform a software repair using Xperia Companion.

Keep us posted on how it goes.
