Hello @tural1015, welcome to the community!
I'm sorry to hear about your phone. Do you do anything specific when this happens, and can you tell me exacly what the message says?
Have you had the option to test your phone in safe mode (Clickable link)? In safe mode, all third party applications are temporarily deactivated, but you can still use the basic functions like calling and text messaging, accessing the Internet and using the camera. We use safe mode to make sure that the behaviour you are experiencing is not casued by a downloaded application. To exit safe mode, just restart your phone.
If the behaviour still persists in safe mode, I suggest that you do a backup using Xperia Companion and the proceed with a software repair using Xperia Companion. A Software repair will remove all software in the phone and reinstall the latest available version of the android system, so be careful and do the backup so you don't lose any important data stored on the internal storage. Data stored on a SD-card or cloud service will not be affected.
Let me know how it goes, and have a nice day!

Hi again @tural1015, I'm really glad I could help! 
Unfortunately, it's a bit tricky to find out which one of your apps that causes this behaviour. I suggest that you start with going to the Google Play Store and make sure all your applications are updated. You do this by tapping Google Play Store > the three lines in the top left corner > My Apps and Games > Update all. If you still get the error, I recommend that you uninstall or deactivate some of your downloaded applications a few at a time to narrow it down.
If there's anything else your wondering about, feel free to ask. I'm happy to assist you if I can.
