Troubleshooting guide

Touchscreen not working

If you notice any display issues like listed below, please follow the troubleshooting steps
Touchscreen not working
Ghost touch
Dead Zone
Delay response/unresponsive touchscreen
Touch screen broken
1. Check whether the issue is permanent or random.
2. Make sure the temperature where you use your phone is neither too hot nor too cold.
3. Check if the issue occurs when charging. If yes, we recommend trying another charger and data cable
(Note: The voltage instability of charger and data cable may cause touchscreen unresponsive issue).
3. If there is a screen protector on the screen, try if it works after removing it.
4. Make sure there are no stains such as water, sweat etc. on the touchscreen, if there is, wipe the screen and
try again.
Note: The standard working temperature of the capacitive touchscreen is -10℃-45℃, and the lowest
temperature will cause the touchscreen unresponsiveness.
Reminders
1. Please back up all the data, clear cache and flash to the latest OS version. (download OnePlus Switch app
from the Google Play store to backup data easily)
2. If such touchscreen issue only occurs when using the individual App, we suggest clearing the cache and
installing the app again (this could be application incompatibility issue.)
Besides,
1. If there is obvious water stains or damage including screen crack on the handset , It is recommended to
apply for after-sales service without checking the steps mentioned above.
2. If the issue can not be solved after flashing the official Oxygen OS version, we recommended applying for
after-sales service.
