Update on 14 November: OnePlus has fixed the issue in the latest OxygenOS 9.2.5 update and now the under display fingerprint scanner works perfectly fine regardless of the wallpaper you’re using on the phone.
OnePlus has finally unveiled the OnePlus 6T, the latest flagship smartphone from the company, which features a bigger display with a waterdrop shaped notch, a larger 3,700mAh battery, and most importantly, an under-display fingerprint scanner, which we can finally talk about.
OnePlus claims that Screen Unlock on the OnePlus 6T is capable of unlocking the device in just 0.34 seconds, compared to the OnePlus 6’s 0.2 second record.
I’ve been using the device over the last week and except for one (major) issue, I haven’t faced any problem with the in-display fingerprint scanner on the device yet. OnePlus seems to have forgotten one crucial factor while optimizing the fingerprint scanner and that might very well cause the downfall of the OnePlus 6T, unless OnePlus addresses the issue with a prompt software update.
Changing the wallpaper back to one of the included stock wallpapers instantly resolved the issue, so I thought it might have had something to do with the bright colors used for the wallpaper, which might be hampering the reading accuracy of the optical fingerprint scanner. I also tested out the issue by changing between several different wallpapers, using different wallpapers for the home and lock screen, using a stock wallpaper on the lock screen while using a different one for the home screen, and vice versa. Alas, the issue persisted.
We’ve reached out to OnePlus to know more about the issue, but we haven’t heard anything from the company yet. So unless OnePlus manages to fix this issue and roll it out as soon as possible, it might have a significant effect on the user experience delivered by the OnePlus 6T.
