[Android Central Question]

I am trying to add my fingerprints. It keeps telling me to press harder and just won't accept that I am. I returned the first phone thinking it was broken and they replaced it. I am having the exact same issue. I do not have very deep ridges in my fingerprints, could that be part of the problem?

It's hard to say but do you have extremely dry skin due too cold weather or other conditions? To rule out whether or not it's the phone or you, you could have somebody else try to register their prints just to see if that makes a difference.

And just in case, make sure there are no other screen protectors (other than the supplied one) on the screen that might be blocking the sensor. Remember that this sensor does not work well with thick protectors and only a handful of tempered glass ones are actually compatible.
