Next day I called for update and got answer battery replacement has been done I can collect my cellphone. Reached at service center, did payment Invoice no “”, received the cellphone get out from the service center, and walking toward my vehicle and realize cellphone screen automatically unlocked, it happened multiple times within 2-3 minutes when I press power button to lock the screen within 1 minutes it’s unlocked, checked setting, turned off double tap to unlock screen but still same, so beck to service center within 5-10minuts and explained the issue, customer representative check setting and update me to resubmit the cellphone again will check and will call you once it’s ready. Next day i received the call and reached to the service center but found the same issue and same showed to the customer representative, again they updated me to submit the cellphone will update you once it’s ready. After 2 days I received call from the service center and they updated me this problem has not been resolved you can collect the cellphone.
