6 problems with the Samsung Galaxy S6 / S6 Edge and how to fix them
July 04, 2025
(Update #1 – Updated with a permanent fix for Problem #2)
The latest additions to the flagship Samsung Galaxy S line brought with them the major overhaul in terms of design and build quality that was long overdue. Apart from their now more premium glass and metal unibody designs, Samsung also created a lighter, and therefore far more fluid and stutter-free, iteration of their TouchWiz UI, which was perfectly optimized with their in-house processing package, making for snappy and incredibly fast devices. Of course, there is also the Galaxy S6 Edge, with the two curved edges present just not for the sake of aesthetics, but with their own set of features as well. While not without its compromises, with the removal of key features like microSD expansion and replaceable batteries, the Samsung Galaxy S6 and Galaxy S6 Edge are fantastic additions to the high-end Android smartphone world.
That said, as is the case with any smartphone or tablet, the latest Samsung flagships are not without its issues. Which is why, we’ve rounded up some of the more common issues that plague Samsung Galaxy S6 and Galaxy S6 Edge users, and offer potential solutions on how to fix them.
Disclaimer: Not every Samsung Galaxy S6 and Galaxy S6 Edge owner will face these issues, and it is actually more than likely that you won’t come across any of the problems listed below.
Problem #1 – Fingerprint scanner issues
Quite a few users have reported facing issues with the fingerprint scanner not recognizing the saved fingerprints and asking for the backup password. Further, the backup passwords aren’t being recognized either, and future attempts to reset the password are not being set. Lastly, some users have reported that on unlocking the device using the finger scanner (for those that it works for), the device opens up an app randomly, without any changes to the settings being made.

Problem #2 – Missing toggles from the Quick Settings menu in the notification dropdown
Some users have noticed that the mobile data, Wi-Fi hotspot, and private mode toggles are no longer available in the Quick Settings menu in the notification dropdown.
Problem #3 – Auto-Rotate not working
Some users have reported that the auto-rotate feature on their device is not working. While this is more common with the Samsung Galaxy S6 Edge, a few regular Galaxy S6 owners have also reported this concern.
Problem #4 – Auto-brightness is turning off
Many users have reported finding that the auto-brightness setting keeps getting automatically turned off. After turning it on, it seems to go off again in 20 to 30 minutes.
Problem #5 – “Unauthorized action has been detected” error
Quite a few users have noticed a pop up security message stating “unauthorized action has been detected” within minutes of turning on a new phone. Even a factory reset seems to fix this issue only for a few hours, and some users have noticed that error after the last software update.
Problem #6 – Connectivity issues
As is the case with any new device, there is a chance that you might face issues with connecting to Wi-Fi and Bluetooth.
