Sprint Samsung Galaxy Note 9 security screen lock bug after One UI 2.1 update will be fixed with the next update

Samsung’s One UI 2.1 update brings a boatload of improvements as well as some new features for eligible devices. It first made an appearance with the launch of the Galaxy S20 series and has since then made its way over to other phones.

Ats the beginning of this month, the Galaxy Note 9 on Sprint began receiving the One UI 2.1 update. While this new software version does bring along improvements, it also appears to have brought along a new bug.

Fortunately, this issue does not appear to be widespread. However, some Sprint-branded Note 9 users who installed the ETF3 build are unable to enter their screen lock credentials. To be more specific, after installing the update once the phone reboots content on the screen is zoomed in.

Thus, users are not able to enter the pin since most of the numbers are cut out. Earlier, we reported on a similar issue affecting T-Mobile-branded Galaxy Note 9 units. In that case, it appeared the issue was caused due to a display resolution bug on the Galaxy Note 9.

Fortunately, Sprint has acknowledged the problem and has also provided a temporary workaround. According to the carrier, the issue arises when the following settings are being used on the device:

– Screen resolution set to WQHD+
– Screen lock is ON (Pattern, PIN, Password)
– Secure startup is ON


Therefore, the temporary workaround to fix the bug is to switch to FHD+ resolution or lower on the Galaxy Note 9. Further, you should toggle off the secure startup option. Alternatively, you can take a look at other official temporary solutions from Sprint here.

In the meantime, Sprint is also working on a permanent fix for the issue. It will be available with the next software release, according to the carrier. Unfortunately, there is no ETA provided for the update.

As usual, we will keep track of the situation and will post an update if and when a new development arises. Speaking of updates, you can check out our Samsung Android 10 update tracker to know when it arrives on your device.
