I black dot suddenly found at the right side corner of the screen. Raised a complaint to the Apple Care and unfortunately by Appale Care expired on July 2025. Based on their request I given my phone their authorized service Centre and got a report mentioning that no mishandling. I purchased the phone from Du Telecom on an 24 months installment basis and another one year installments is pending. Finally Apple customer care told me to approach Du telecom and give a request. I’m sure that there is Nothing to do with.them and they clearly neglected my case. No Apple also refused to do the replacement.
