Unreliable Fingerprint scanner

[Novaprime]

So it seems my previous post didn't show up. I have had a op3 since launch. Amazing. LOVE IT.

Only issue is my fps which is hailed as amazing is only 50/50 success with me. I have:
- Replaced fp many times
- cleaned scanner
- restarted
- changed case cause previous one interfered a bit
- even clean fingers first sometimes.

My old country needed fingerprints for driving licence and I remember having issues with normal ink and paper fingerprints showing clearly. Maybe that?

Any suggestions? Or is it likely factory issue?
Cheers.

So now I see my previous post has showed up. Good grief.

Seems like you have done many of the things I would have done so far.
I would also clear the cache partition as well. (I doubt that would help but it's not invasive)
Next would be a factory data set.
If that doesn't work, contact OnePlus. Could be a hardware issue.

Yeah cheers. These are the things I have been pondering. I may put the community build for 3.5.2 on so maybe after that it may change.

Looks definitely like a hardware issue. The FP is one of the fastest on the market.

Being fast and being accurate are two different things though. I agree, this baby is nearly instantaneous...when it reads your print.

However, to me, I'm a little skeptical it's a hardware defect, especially since he's had issues with his prints in other scenarios. These things are real sensitive, and rightly so for security/privacy purposes.
