After Latest Update: Two Lines on Screen + Battery Draining Fast (Galaxy S21 5G)

[HaXon]

After the most recent software update (One Ui 7) on my Galaxy S21 5G, I started facing two serious problems:

1.Two faint lines suddenly appeared on my screen.

2. The battery is draining much faster than before — even when the phone is idle.

These issues only started after the update, and I never faced them before.

I am not looking for a quick fix — I want to report this officially so Samsung can check if the new update caused it.

Please investigate this issue for Galaxy S21 5G users.

Thank you.

Now a days lines are most commn for samsung mobiles and if you go to service center for replacement they simply check it and say your mobile got rejected by company to do free replacement according to company policy and you have to bear the expenses for changing the screen....its a total scamming by samsung
