Launcher not responding or something like that

[SW Cheung]

1. I last my wifi connection (N, 5G)
2. I power off my Nexus & power it on again
3. It stuck at the booting X logo
4. I power off again & power it again
5. This time it boots up and get some error like launcher not responding and all my desktop shortcuts are gone

Anyone encounter this?
Ps. I am using the stock launcher & not rooted my N7. I only install programs from the play stores (the sames one I install on my N4 & N7 2012).

And what happens if you reboot again? Still the same launcher error? Try rebooting to Recovery Mode and wiping the cache partition. Discussion thread here: http://forums.androidcentral.com/go...nexus-7-not-booting-how-do-factory-reset.html

It has the launcher after I shutdown and restart it. After that I reset to factory setting via setting and so far it has happen again.
I think it is related to wi fi. I switched to 2.4GHz N now.
