Apps Keep Stopping

[AC Question]

Hi all... I have a Sony T3, a while back the phone shut off and then got stuck booting up and kept looping on the blue wave screen. I used the Sony Xperia Companion software to format it and reload the operating system. I've put the Natwest banking app, facebook and messenger, andriod pay, and whatsapp back on. However I'm now finding that random programmes wont start the first time and I get the message on screen ''unfortunately !!!!! has stopped working''.

Anyone any ideas?

You have problem with operating system. More details you can get you check the logs with logcat. But I don't think buy the crash stack you will be able to guess what is the problem.
Did you try to run system update? Fresh OS will fix your problem.
