Several users are reporting touch screen issues with the OnePlus One it appears to be that the touch screen has issues when trying to detect 2 fingers on the screen when they are close together, the bug doesn’t appear to affect any other way of using the touch screen like swiping.
Cyanogen has confirmed that the issue is on the software side and all though they are still working on a fix which was expected to become available in July but due to Google’s slow approval process it hasn’t been released yet. But don’t worry, there is a work around for the problem:
How to fix the touch screen issues on the OnePlus One
- On your device, download the Android Terminal app here
- Open up the app and type “Su”
- Make sure it says “root@A0001”
- Write the following command: cat /sys/class/input/input0/baseline_test
- Press enter
- catting that file seems to put the touchscreen in some kind of calibration mode, fixing the issue (the fix is a temporary fix and after rebooting your device several times the issue may come back, re doing steps 1 to 5 will fix it again.)
