Purchased a shiny Galaxy S6 Edge and you were excited for the night edge display feature which allows you to display a clock on one of the edges of the screen while the rest of the screen remained off? You want a night clock, not a night light!
In theory it is a good idea, but if you are like me, your Edge didn’t do that. In-fact, your whole screen would glow, the night edge clock would show but the whole point of it was lost. This means your battery if your phone is not charging over night would drain quite a lot.
This is in-fact an issue that seems to affect only a certain amount of Galaxy S6 devices. My fiancées Edge doesn’t have the issue, but mine does.
Apparently Samsung are working on fixing the issue as it is software related and in some circumstances, is related to particular carrier variants of the S6 Edge firmware.
Over at the XDA Developers forum there is a fix for certain firmware versions. But the fix requires flashing your device, thus tripping Knox and voiding any warranty on the device.
The best course of action is to wait for the fix to be pushed out in your latest carrier update. Speak with your carrier about when the latest firmware update might drop.
