    A while ago I changed my battery in my my RN4 and we’ll I assume I got a defective battery because the Temperature doesn’t cross 25 degrees.
    A few days later my fingerprint stopped detecting, I deleted and tried to add back new fp but no luck, kept failing.
    I went ahead and bought a new sensor,just installed and same issue.
    Also tried dev rom and stable and epic rom same issue. I did a hardware test and it says pass.
    Self test :Pass
    Checkboard test(number of dead pixels – 0

    I WISH could totally turn this off 100% so that finger does NOT wake up screen at all, it is SO ANNOYING, I had seen plenty of people make this recommendation and Xiaomi never “responded” saying would add this “simple” feature…it should be a simple “toggle” to activate the feature or toggle to have it OFF for people who “do not” want it (so annoying as I have had phone “wake up” with nothing touching the sensor, and yet touch sensor again does not put back to sleep go figure).

    all the suggestions for disable it have no effect, just “take back of phone apart, take out the wire for the sensor, problem solved” or “put a layer or 2 of tape over the sensor”
    blekk and double blekk.

    figure it would be “easy enough” to add ability to “toggle off completely” as if you root the phone you can completely remove the code allowing the sensor to work, but if you “screw up” you just bricked your phone. a few lines of code would allow a “toggle”
