From past few days, my Oneplus 2 home button and finger print sensor stopped working. Even in the Setting, (Setting – Security & Fingerprint), Fingerprint module was missing. I tried many ways like loading the latest oxygen patch / wiping the data & cache etc., but nothing worked. I then contacted Oneplus service center, they told most probably the hardware would have got damaged. Need 2 to 3 days to fix it and might cost around INR 4000 to 5000 /-. But, I didn’t give it to them. My friend helped to recover the fingerprint back on my mobile. Follow these steps, it worked for me:
Press Power button
When you see (Power off, Reboot, Screenshot).
Keep pressing on “Power off” for few second. It will ask for “Reboot to safe mode”, click OK.
Go to Setting – Security & Fingerprint.
You will see “Fingerprint” module.
Set the Fingerprint again.
Check it works for few times by locking and unlocking the phone.
Power ON as Normal.
By this, I was able to safe almost INR 5000 easily. Hope, this is beneficial to you too.
