Hello fellow Xiaomi users,

Been having Redmi Note 4x SD 64GB 4 RAM for a couple of months now and it had been working flawlessly however, recently, a few weeks ago the fingerprint sensor started acting up randomly. It does recognize my fingers or at least I believe so, as it doesn't vibrate, but it just wakes up the phone into lockscreen instead of unlocking it. This happens randomly, I haven't noticed a pattern to this, it just works and then decides to just wake the phone only.

Phone is rooted since 2 days -have TWRP installed and rooted with Magisk.

Android: 7.0 NRD90M

MIUI Version: MIUI Global 9.5 | Stable 9.5.8.0 (NCFMIFA)

What I've tried so far:

1. Clean sensor and re-register fingerprints
2. Register fingerprint, remove lock, then remove fingerprint and register again or something similar, saw it as a suggestion in a thread on XDA for a similar issue.
3. Wiped phone cache with Xiaomi_ADB_Fastboot_Tools_2.0.0.2

Looking forward to any suggestions.

Sounds as hardware failure. Working with the latest eu stable ROM, you'll test with.
 
Don't think so? Wouldn't it be working at all if it were to be a hardware issue?
ItsIas if the sensor itslef is on a standby mode randomly.
It does work most of the time.
