it's NOT edge lighting. It's game booster telling you it's lowered your volume and is throttling your CPU to cool off your phone. Really DON'T need to interrupt my gaming with flashing lights to let me know every five seconds. And of course, it's yet another feature that Samsung won't let you turn off on the device you purchased.
it's definitely game booster and it's definitely YET ANOTHER obnoxious feature that Samsung won't let you disable, just like that Norton "secure wifi" subscription advertisement they push to your phone if you won't pay for it. Yay. Really miss my iPhones.
Samsung won't the freedom to disable it if you don't want it but I revoked it's permission to display on top of other apps so I'll report back if that works. I game many hours a day so this is really obnoxious. Hopefully this works. 😑
yeah, Samsung going back to my iPhone beside me and returning this, now every time I open a game, this popup is in my face. I don't feel like rooting so I'm just getting rid of this trash.
I can't say for certain but I think it's to let you know your phone is overheating. After having this same thing happen while playing on my s9, I did some digging and some phones will even lower the brightness or slow down a game's fps when the blue light happens. I started paying attention to how hot my phone was when it flashes across the bottom of the screen and it seems to make sense.
