Help/Support Touch ID Activation Failure - Battery Draining!!

PARADOX-X · October 15, 2017

Hi, I recently dropped my phone in water and got it repaired, my touch ID isnt working anymore apparently due to water damage.

My phone is displaying "Touch ID Activation Failure..." and constantly trying to activate it which is draining my battery majorly. Battery life lasts less than 2 hours now..

does anyone know how to fully disable Touch ID activation process or have any solutions?

Go to passcode and turn it off.

Its already turned off, the TouchID hardware isn't actually functional hence why my phones trying to activate it constantly!

This is a common fault with all Touch IDs and in 3rd party screens

Once the screen has been changed the Touch ID no longer works because the security settings do not match.

When changing a screen that has Touch ID the first thing that should be done is the Passcode and Touch ID should be disabled.

Your old home button with Touch ID has let's say been "Paired" with your motherboard, the two can communicate with each other and recognise your FingerPrint.

The new home button with Touch ID has no idea who you or the device is.

Your motherboard has no idea who the new home button and Touch ID are.

The two can not communicate anymore and unfortunately never will without a few drastic moves.

1st Option would be to get your old home button with Touch ID and the flex ribon back and install it with the new screen, this would still require you to possibly reset or restore the device this is Not advised if you are Jailbroken, in some cases simply putting back the original home button with Touch ID and flex ribon fixed the issue.

2nd Option is risky again if Jailbroken but some users have fixed the issue by restoreing the device but remember this has only worked for some users, others still have the issue after the restore.

3rd Option is to replace the whole flex ribon as who ever changed the screen could have possibly damaged either your Touch ID sensor or your Touch ID Ribbon Cable that runs behind the LCD Shield Plate.

Your Touch ID ribon can be replaced.

If the ID sensor is damaged you will need assistance from Apple.

Hope I cleared a few things up

Very informative thanks!

I will just have to deal with this, it’s my only jailbroken idevice left so it’s not worth restoring and apple onced updated my iPad to the latest ofw so I won’t go there!

Do you think if I remove TouchID function completely this problem would be solved ? I don’t really need it but dont know if it’ll be safe removing it

sorry for the late reply
