Greetings everyone
I have a problem with fingerprint unlock in Codebook. I have a Xiaomi Redmi Note 4 (Android) using Lineage OS 15.1 and had a support issue open at the time that has been closed, but I’m still wondering about this…
Admittedly:
- Lineage OS is a custom ROM
- They state on their page that there exists an issue with the hardware maker of the finger print sensor
This was the reason my support issue was closed…
However, I really, really question the fingerprint unlock implementation that Codebook uses because every single other app that I have, including the very OS itself that unlocks the phone, is able to use fingerprint unlock / authentication. Codebook is ONLY ONE not being able to use fingerprint unlock. I just don’t understand this. The phone is not rooted, although I know that’s not an issue. Codebook fingerprint unlock worked with Xiaomi’s MIUI. I’m using Lineage OS because Xiaomi won’t release an Android O or later version for the RedMi Note 4.
My only conclusion is that the way Codebook calls the fingerprint api, is causing failure with this setup as every other app (Paypal etc.) can use fingerprint unlock.
Any positive ideas?
