Some Nexus 7 (2013) units still have touchscreen issues after the JSS15Q update

Touchscreen issues still affect some Nexus 7 (2013) units, even after the recently released JSS15Q software update is installed.

The Nexus 7 (2013) tablet experienced some annoying bugs after its launch, including GPS issues and touchscreen problems, both acknowledged by Google and supposed to have been fixed by a recent software update.

However, it looks like the touchscreen issues are still there for some new Nexus 7 buyers, even after the JSS15Q update is applied (see video below).

Android Police speculates that some of these Nexus 7 units that still present touchscreen glitches may have been calibrated incorrectly – but such a problem could be solved via a second software update.

However, even if a second software update is released, it may not completely fix the issue in case Asus used various touchscreen digitizer types when manufacturing the tablet.

Another explanation offered for the problems is a grounding issue, which can’t be fixed with a simple software update:

[quote qtext=”The origin of this theory comes from a specific symptom where the tablet doesn’t experience any problem while being held or connected to a charger, but erratic behavior and ghost touches start occurring while resting on a flat surface. Again, these are only educated guesses and have not been validated by Google or any third party.” qperson=”” qsource=”” qposition=”center”]

Paul Wilcox from Google’s Product Support forum has confirmed that the company is still looking into these remaining touchscreen issues, so we’ll probably learn more details about it in the future.

Meanwhile, in case your new Nexus 7 still behaves erratically, you can always have it replaced.

Have you had any Nexus 7 issues? Did the touchscreen issues persist after the JSS15Q update?
