my s21 ultra have soft green screen everytime even in AOD. ITS NOT COMPLETELY DARK BLACK. even i turn all themes off it shows every time.

my camera cutout also misplaced. its little bit down from the original place. it can be noticed while scrolling third party app because it overlaps half over the apps. it can also be noticed in lock screen where i have face unlock enabled and white circle is little bit top of the notch while it search for the face. 

my motion smoothness is adaptive but i never get 120 hz feeling. it gets even slower while scrolling and heats up my phone. 

Can anyone suggest me the solution and what is the problem software or hardware?

i have android 13 One ui 5.1 with latest November Security Update

s21 ultra International Version

Most time the green screen is an issue coming from faulty hardware, hope your screen wasnt just replaced and as for adaptive smoothness you can check if screen is using 120 hz after activating developer options by opening settings, open about phone then software information ,tap build number 3times and developer options will be activated, open developer options and turn on show refresh rate you will be able to check if really 120hz or 60hz is what your using ... or the last option could be a factory reset incase some malware was installed all will be erased . If that doesnt help you need to visit a samsung outlet

We apologize for any inconvenience this may have caused you. Kindly make sure that you have the last software update. Also, please try to do factory reset. Please note that a factory reset will restore your device to its default settings, and all data will be erased. It's essential to back up your data before proceeding. Here are the steps for both data backup and a factory reset:

To back up your data:

Open your device settings and tap on "Samsung account" at the top of the screen.
Select the "Samsung Cloud" option and tap "Back up data," "Restore data," or "Settings."
Find Samsung Cloud in your Samsung Account or access the "Account and backup" menu in device settings to do a backup.
On the next screen, you can select the items you want to back up and tap "Back up now." You can also enable "Auto Backup" to automatically back up selected items every 24 hours.

To perform a factory reset:

Launch the Settings app and tap on "General management."
Select "Reset."
Choose "Factory data reset" and review the information provided.
When you are ready to proceed, swipe to and tap "Reset."
Tap the "Delete all" button to continue with the reset, which will delete all information stored on your phone.
After performing the factory reset, please check if the green line issue is resolved. If it persists, we kindly request you to submit an error report to our dedicated technical team.
