[ChandraSekhar09]

Hello IN MY M21 There is a blue Line coming at Bottom of screen while playing games only. Is there any solution 

[indiantrueindian]

[ChandraSekhar09]

yaa

[indiantrueindian]

then try to launch the same game outside game launcher
and if the same issue presists then problem may be in app

[indiantrueindian]

please give a snapshot or screenshot of the issue

and if there's not the blue line coming it probably a hardware problem

That's game launcher tool to monitor cpu and temperature thing..if you want to turn it off..then turn off temperature control tab..

It tunes brightness and CPU speed to lower temperature

Something that I found works. Go to settings, go to apps, go to Samsung apps, scroll down to Game Booster and tap on it. Scroll down to Game Optimization and change the setting to battery saver. Restart. Sent on Galaxy Tab S7+ tablet with android 13.
