Read carefully first. Two months ago, I had a bike accident and the phone fell, causing the corner of the display to break and the back to crack slightly. Since it has been lying around for 2 months, I do not remember the phone lock. I tried a lot but could not unlock it. Later, I bought another phone, Vivo V30 Pro 12/512 GB, from Jamuna Future Park. The phone is 100% good and the display works 100%. The 12GB 256GB phone does not hang. Thank you.
