Less than a week ago, we reported that Google released a new Nexus 7 (2013) update which apparently fixes the multi-touch issues as well as the GPS bug that accompany the tablet from start. However according to a number of users, this update doesn’t seems to fix the touchscreen issue at all. Some of the most common problems is the touchscreen calibration for the Nexus 7 (2013) as well as grounding problem, which is no doubt a very annoying experience for the users.
So if you happen to own one of such problematic unit, it is recommended that you go for an one for one exchange instead – rather than trying to solve the problem by any software updates. Likewise, if you found that the previous Nexus 7 (2013) update actually resolve the issue, do share with us as well.
