If you talk about a phone try a hard reset or roll back to wp8.1 and try again with a fresh install to get it more stable.
Or roll back to wp8.1 and wait a few days because a new TP is coming soon which may or may not be more stable.

But do not forget it is a TP which can cause all kind of issues so "Don't do the crime is you can not do the time".

Good Luck.
