The other day the camera, fingerprint sensor and accelerometor on my Galaxy Note 9 all stopped responding at the same time. When i open the camera app, nothing shows and the app sort of hangs (tapping the take photo button does nothing), the fingerprint sensor doesn't respond when i try to unlock the phone, and the phone doesn't auto-rotate. The phone is also overheating all the time and drains the battery 100-0% in just four hours (usually it was a day and a half). It kind of feels like the phone is trying to find the unresponsive parts and is burning through the battery in the process. Makes me think it's a hardware issue.
Phone is fully updated. Rebooted multiple times and cleared partition cache to no effect.
Running the *''#0''*# diagnostics none of the sensors in there are responsive either.
I'm opting to factory reset it and then pop the phone open if that doesn't work. Does anyone have suggestions before i do so? This is my personal phone so i'm hesitant to do anything too permanent before i do so.
