Given you are having issues like this, I would recommend you restore your phone from backup using your home computer with iTunes.
See the directions in this link --> Restore your iPhone, iPad, or iPod touch from a backup - Apple Support
You will need to backup your phone to iTunes on your computer before you restore it.
