Google nexus 7Update JSS15R is rolling out for the 2013 version Nexus 7 and it may fix the multi-touch and random reboots issues.Apparently a new OTA update is rolling out for the WiFi Nexus 7 model. The update is a small one and it may or may not fix some of the most common issues that users are experiencing all over the world. The update is still Android 4.3 and has build number JJSS15R. Google hasn't presented an official changelog so we will have to check with users that have installed this to see what changes are brought to the device. You should receive the OTA update on your device anytime now, just go to Settings and About Tablet and hit the 'check for updates' button.

Update JSS15R and the multi-touch issue

The multi-touch issue on the Nexus 7 is something that many users have been facing, so it is safe to say that it is a common problem with the tablet. More specifically, users have been reporting random presses on the screen, especially on the keyboard, without touching the screen in those places.The previous update, JSS15Q, was supposed to fix this, but while some users were reporting a better screen behavior some were reporting worse or no change at all. This time around, judging from the comments left by users that have updated their Nexus 7, it seems that update JSS15R had no effect on the multi-touch issue whatsoever. Except for the usual few users that are reporting better behavior, the majority is indicating that the issue is still there and the update did nothing to fix this. This means we are still waiting for an efficient fix for this annoying problem.

Update JSS15R and the random reboots/freeze issues

Another common issue with the 2013 Nexus 7 is the random reboots and freezes reported by already a lot of owners. However the update seems to be noneffective once again, because the users that were experiencing this before continue to have the issue. So no fix in this area either.So with these issues still being there, it seems that update JSS15R only brings in some security improvements and small bugs. Nothing important about this update so far. However it is wise to wait for more feedback from users that have installed the update to give a more accurate response on the update.

Install OTA update JSS15R from stock recovery using adb sideload or using a Custom Recovery

Before installing this, make sure you are currently running on an unmodified version of JSS15Q. This will not work with any other ROM. If you flash this using stock recovery you don't need an unlocked bootloader.Installation steps:
  1. Download OTA JSS15R. Copy this to the sd card.
  2. Turn off your tablet. Press and hold Power + Volume Up. When you see the Google logo release the buttons. On the next screen press and hold Power and then press and release Volume Up and release Power. This will open the recovery menu.
  3. Choose 'Apply update from ADB'. Navigate with Volume down and choose with Power.
  4. Adb sideload the zip file from step 1.
  5. Your device should start updating right now.

Install pre-rooted, odex/deodexed JSS15R update for Nexus 7

Download either the odexed or deodexed version from here. You should have a Custom recovery installed already and some previous experience with using them. Remember that installing this will eliminate the possibility to install OTA updates.After you are done downloading the files, place them on the virtual sd card and flash using either TWRP or CWM recoveries.If you have received the OTA update JSS15R on your Nexus 7 or if you have manually installed it, please share your experience with the new update with us. Has this fixed any issues for you?
