Hi @baileyboy110
Try using the phone in [https://www.hardreset.info/devices/nokia/nokia-g300-5g/safe-mode/|safe mode] and check if it works OK.
If it does then a ''downloaded app¹'' may be the cause of the problem. The trick is to find out which one. You will need to uninstall each downloaded app, one by one, and then test the phone in "normal" mode between each uninstall to see if it works OK or not. When it does then the last downloaded app that was uninstalled was the culprit. A ''downloaded app¹'' is one that you downloaded and installed and wasn't already pre-installed on the phone.
