After the last December 2020 security update, we've heard many users facing difficulties with the pixel 4a 5G touchscreen. Issues of faulty navigation people complained about on google's support forum and XDA forums. Google acknowledged the bug and promised to fix it.
A Google specialist wrote on the official forum page that they were aware of the issue and that it will be fixed in the next upcoming update. He also gave a couple of suggestions on how to improve the device responsiveness:
- When tapping icons at the edge of the screen, we need to tap the center of the button or the side of the button/icon ich is the furthest away from the edge of the display.
- When tapping icons or the navigation buttons at the bottom of the screen, use the tip of the finger or the thumb instead.
It isn't clear when Google plans to issue the promised fix for the Pixel 4a 5G's touchscreen problems. It didn't roll out with the January security update so it could still be some time away. Until then, you'll just have to live with the aforementioned workarounds even though they might not be the most intuitive ways of navigating your phone.
