    • Apply a suction cup to the heated bottom edge of the back cover.

    • Make sure you did not mistake the screen side for the back cover side.

    • If your back cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere.

    • Lift on the suction cup with strong, steady force to create a gap.

    • Depending on how aged your phone is, this may take significant force. If you are having trouble, apply more heat and try again.

    • Insert an opening pick into the gap.

    • Don't use metal tools to pry, or you'll mar or shatter the glass back cover. If the panel won't budge, apply more heat, either with a hair dryer or heat gun.

Is there any steps to be done on the software side? I did the replacement but I cannot see an option to setup fingerprint unlock.

Moe - Yanıt

Hi Moe,

The fingerprint sensor setup should still remain the same. If you can’t any software setup option, it may mean that the phone doesn’t detect the fingerprint sensor hardware. Look over step 9 and carefully check that the connector is fully seated.

My NFC stopped working at the same time as the fingerprint sensor, because I accidentally broke the fingerprint sensor flexcable when replacing the battery.

I've now replaced the fingerprint sensor and flexcable, and it's working again -- but the NFC still doesn't work. I have no idea what to try next!

Hi Lisa!

The NFC and wireless coil attaches to the phone with spring contacts. I'd suggest checking if the contact pads clean and correctly aligned. Here's a step depicting them. Since they're spring contacts, they also require some force to keep them connected to the phone. If you have the back cover open, you can press against the area where the spring contacts are as you test to see if it's a contact issue.
