Some Google Nexus 7 (2013) Units Having Multi-Touch Issues

We reported previously on the GPS issues that the Nexus 7 (2013) is having. While this problem seems to affect a lot of units another problem which some owners are complaining about is regarding the touchscreen of the device. What happens is that it registers double taps on the keyboard, ghost taps, and erratic behavior from the touchscreen.

A member of the xda-developers forum posted this problem on the new Nexus 7 (2013) he bought and since then has had lots of comments on his thread from people experiencing the same problem.

In his post he states that

“I’m noticing intermittent bouts of erratic multi-touch on the Nexus 7 (2013) 16GB. I exchanged one device already hoping that it was a HW defect, but my second device behaves in exactly the same way.

Chrome, Dolphin, web-view, maps (especially maps) will often jump all over the place during pinch-to-zoom. Sometimes it works fine, but too often, it jumps zoom levels erratically. Edit: This also manifests as double taps and/or “ghost taps” when using the keyboard.

I’ve installed YAMTT (Yet Another Multitouch test) and I’ve observed the touch points disappear, change direction and even suddenly register a 3rd touch. None of my other devices do this.

I’m reluctant to exchange the device yet again, but I haven’t read about anyone else who’s witnessed this. Am I alone in observing this behaviour?”

Some owners said that the problem gets so severe sometimes that typing on the keyboard or even playing games can be difficult.

Other members suggested that it might be third-party apps that may be causing this problem. One way to check on this is to start the device in safe mode and see if the multi-touch issues will still occur. When the device is in safe mode it temporarily disables third-party apps.

Yet other owners of the device say that it works fine straight out of the box but as soon as they updated to the new JSS15J update the problem then occurred.

Some solutions to this problem that works for some people is to put the device in recovery and wipe the cache and Dalvik cache. After performing this, the touchscreen issues disappeared. This solution may not work on other devices with the same problem.

Do you own the Nexus 7 (2013) ? if so, are you experiencing the same problems?
