Only display changed. 1:1 bezel less OLED display installed for 16000 taka. My brother sent the phone from Saudi Arabia.. total 13 months used. After 8 months of use, it fell from hand and the display cracked.. then I am using it after installing a 1:1 bezel less OLED display from Motaleb Plaza ifix. Face lock, finger, all sensors 100% ok. All cameras 100/100. Urgent money need.
