My s23 phone is overheating now and then, sometimes when I take a photo. Software uptodate

How can I customise LockStar in lock screen

I got blue line in my s23 display, it is out of warranty. I approach service centre, they changed display with free of cost but levied rs 649 as service charge.Because of manufacturing defect from samsung why I pay for the service charge?I want sams...
