Hi,
My Nexus 7 2012 (very first batch) is quite often behaving really slowly. It is common for the settings screen to take 15-20 seconds to open. From the homescreen. With no running app.
Here is a video after I've reset everything to factory defaults, let it run and index things on its own for an hour and then manually upgrade a small app:
At other times, the speed is pretty decent for such a tablet. I just can't figure out why this difference. I've tried to check for wakelocks, tried a logcat and many other things. I can't make any sense from it.
Rebooting the tablet seems to have 50% chance of fixing the problem. So it's probably not a memory leak.
The tablet is rooted, on the latest build and I noticed that App Ops X survived the reset but no funky software is installed and the behaviour predates the installation of App Ops X. The network is not a problem here. The 2013 Nexus 7 of my wife works just fine and so does the Nexus 5 taking the above video.
How can I investigate this ? Is there an app that can run various reliable diagnostics to find out what kind of activity is causing trouble ? I tried to use logcat but the result is quite verbose and nothing rings a bell. I would really like to understand rather than just return it and wait or, worse, buy a new device.
Thanks.
