Galaxy S23 users report fingerprint issues after One UI 6.1 update

Samsung Galaxy S23 Plus Review AM AH 07

Samsung appears to have rushed the One UI 6.1 update for Galaxy devices. Users who have installed the update are encountering various issues. Over the past few days, we have seen reports about slow charging speeds and devices running warmer. Now, some Galaxy S23 users say the fingerprint scanner on their device is not working properly following the update.

One UI 6.1 may have introduced a fingerprint issue to the Galaxy S23

According to user reports on Reddit, the fingerprint icon occasionally does not appear on the Galaxy S23’s screen after the One UI 6.1 update. It doesn’t show up when they wake up the phone by pressing the power button or double-tapping the screen. The bigger problem is that fingerprint recognition does not work when this happens. Placing a registered finger above the scanner does nothing.

To make it work, users have to lift their fingers and wait for the icon to show up. The fingerprint scanner then worked properly. It appears to be a fairly widespread issue. We have seen reports from dozens of Galaxy S23 users on Reddit, including a Galaxy S23 FE user (the FE model has an optical scanner while the flagships have an ultrasonic scanner). SamMobile could replicate the issue on a Galaxy S23.

While this happens occasionally, it can be frustrating to users. Hopefully, Samsung has noted the issue and is working on a fix. The company has also updated the Galaxy Z Fold 5, Galaxy Z Flip 5, and Galaxy Tab S9 series to One UI 6.1 but there aren’t any reports about fingerprint issues from users of these devices. The foldables feature side-mounted capacitive scanners while the tablets have optical under-display scanners.

Reports about slow charging speeds may be misleading

Several Galaxy S23 and Galaxy Z Fold 5 users have claimed that their phones are charging slower than usual after the One UI 6.1 update. They shared screenshots from the Electron app, showing a charging speed of 15W or lower. While it isn’t unusual for major updates to contain a few bugs, it is unclear whether One UI 6.1 is the culprit here. Phones rely on various factors to dynamically adjust the charging speed.

The charging speed is usually fast when the battery level is low and gradually slows down as we reach higher levels. The readings reported by Electron may not be accurate either. SamMobile used a pluggable voltage and amperage meter to check the charging speed and found that their Galaxy S23 charges at 20W when the battery level is 47%. This suggests One UI 6.1 hasn’t slowed down the charging of Galaxy devices. We will let you know when we have more information.
