Hi @ethanhunt ,
Try the following to see if it can be narrowed down to a software problem or a hardware problem.
a). Wipe the cache partition and check if this resolves the problem.
b). Start the phone in safe mode and check.
If the phone works OK in safe mode then a downloaded app is 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 test the phone in normal mode, between each uninstall, to check if it works OK. When it does then the last downloaded app that was uninstalled was the culprit. A downloaded app is one that you installed on the phone and did not come pre-installed with the phone when you got it.
c). If still no good, then try a factory restore.
Be aware that a factory restore (aka hard reset) will erase all your data and downloaded apps. It will restore the phone to its factory default condition or last system updated condition. If you decide to try this then backup the phone to the cloud or a computer, using the phone’s backup feature before performing the reset.
Also make sure that you know the phone’s Google User account ID and password (FRP lock) as you may have to use it to access the phone once it has been reset.
Once the phone has been backed up, reset the phone using the phone’s factory restore feature.
Once the phone has been reset, check if the WiFi and the BT now work OK.
If it works OK, when you are satisfied that all is OK, using the backup you made earlier, restore the phone to what it was earlier, using the phone’s restore feature.
If it still doesn’t work after the phone has been reset then there is a hardware problem.
