By Chris Smith August 31, 2013 30 34 244 52 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.Advertisement 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: 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. 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? 30 34 244 previous postOne Touch Idol X, Idol S and Idol Mini quietly listed on Alcatel’s websitenext postHow much thinner can bezels get?
