Jelly bean (i9023) - Sometimes phone does not wake up

---

Google Nexus S i9023
Country: India
Carrier: Vodafone
Android version: 4.1.1 (Stock OTA from Google)
Build number: JRO03E

I've been on Jelly Bean for 5 hours. Apart from discovering that the CRT lock screen animation works only very sporadically (another thread here talks about it), 3 times the following has happened:

The phone was on idle, screen turned off. I woke my phone by pressing power button and nothing happened. I waited for almost 10 seconds, and the phone woke up. It took 10 SECONDS TO WAKE UP.

This has happened very sporadically too. I dont know if there's a pattern when it happens and when it does not. Anybody else here experience this problem?

First time it happened, I had Developer Options turned on. I turned it off.
After the second and third time, I restarted my phone.

That was an hour ago. It has not yet happened again, and I am watchful as ever. If someone else has faced a similar problem or knows whats causing it, please do reply!

I cant imagine what I'll do if this happens when I need the phone for an emergency.

sometimes when i press the power button nothing happen !! and i must press it again !

soft reboot? Happened to me before because I was using LBE app which is not compatible with JB, no more soft reboot after uninstalling the app.

Umm.. even with soft reboot, I would see some activity on the screen right? Like the booting animation or something..?
When I tried waking up the phone, it did not give any feedback whatsoever. It just sat there like a piece of dumb plastic for 10 seconds. And then, it nonchalantly showed me the lock screen as if nothing had gone wrong and I had only just pressed the power button.

BTW, it has been almost 6 hours since I restarted my phone and this incident has not repeated itself.

Don't try to remove the battery and insert again

Same problem was caused by my nexus S I9023 after the OTA update from google for jelly bean.I removed the battery then the system starts booting up without pressing the power button.Then i removed the battery again and suddenly phone stopped booting up.(No display,No usb connection,No power button ,No button combination work to enter into recovery mode)Phone became completely dead It is now hardbricked and became a paperweight....
Now im looking for the repair ..Can anyone suggest what can be done now ???
