I have lost a load of apps. How do i get them back?

[AC Question]

My phone went completely dead last night. When i charged it and turned it on this morning, I lot of my apps are missing. What can i do to get them back. ? I know some of the ones that have gone but some are pre-installed.

Try rebooting your device again, or try booting into safe mode to see if they are there.

I have tried rebooting and in safe mode no luck. Still missing. I think I am going to have to do a factory reset.
