My phone keeps locking itself

[AC Question]

Hi there,
My Alcatel Onetouch Idol 3 with Android 4.4 KitKat is regularly locking itself at random. Can somebody please tell me what they think the source of the problem is , and what solutions are there for this problem.? (If possible one that doesn't include a factory reset of my phone)
Thanks !

Do you mean it freezes? Try clearing system cache. If that doesn't work boot into safe mode and if it doesn't freeze it is likely to be a problem app. You'll have to work out which one

It could be anything. Have you tried starting your phone in Safe mode to see if perhaps a 3rd party app is causing this? Note... the link is a generic Google search since I have no idea who your carrier is.
