Can you put your phone into Safe Mode which disables downloaded apps but leaves the stock ones working and then see what happens @colourlee 

If the issue stops then one or more of your apps are causing this problem. Come out of Safe mode and Start deleting one at a time until the issue resolves.

If the issue remains in Safe Mode then consider a factory reset after backing up and removing any relevant Sd card.
