Hi @liyana96690
Why was it necessary to replace the screen?
Was the phone dropped and the screen cracked or did the phone get wet etc?
Take it back to the repairer and get them to check it out.
Most reputable repairers test the phone before handing it back to make sure all is well and also give some sort of guarantee on their work even if it is only 30 days.
If the phone was dropped or got wet then they should have also checked this out when doing the repair, not just replace parts
