If you did a clean OS reload and tested before restoring and installing apps, then you've likely done all you can do.

If you did not test before restoring and installing apps, but instead restored backup and installed apps immediately after doing the OS reload, then it's possible you reintroduced a data or setting glitch. You need to test clean to avoid this possibility.

If you have tested clean and those functions still do not work properly, then odds are the hardware has failed in some way. If it were me, I would get another device. If it happens that you have a smartphone repair shop that you can consult, then it wouldn't hurt to try that, see if they will give you a free consultation, and then decide from there.
