My touch screen does not register finger placements on the screen.

My camera application is not operating properly.

Screen protector Interference Your screen protector may be the cause of the issue you are having. Remove your phone case and then proceed to use your touch screen. If your phone registers your finger placements, then your screen protector was the cause of your problem. Screen is Locked If your screen is stuck on one image and turns unresponsive, it is usually a software issue. Powering the phone on and off is a potential solution. If the phone’s display does not stay on or come on at all, then the lock button could be interfering. Try wiggling around the lock button or taking the back cover off the phone to see if there is anything interfering. Screen Cracked If the screen is physically cracked or damaged, then a replacement is usually the only fix here.

Cracked lens If you take multiple different photos and there is a discrepancy in the same spot in every photo, then there is probably physical damage to your lens. The damage/debris is obviously in the same spot every time, which lets you know there is a scratch/damage/debris on the lens. This is most likely irreparable and needs replacement. Damaged internal sensors If you open up the camera app and get a black screen or if you try to take a photo and the camera is unresponsive/not working, then there could be damage to the hardware or software portion of the phone that relates to the camera. Try closing background apps, restarting the phone, or backup data and do a factory reset. These methods should rule out any basic software malfunctions. If nothing is working, then there could possibly be internal damage to the camera's hardware. This would most likely require replacement.
