Coincidentally, my phone also hang on Sunday. I reboot it myself and that fixed the problem. Yesterday, my brother's phone hang also, but rebooted itself.

When I say hang, I can't interact properly with the phone. But still managed to select restart.

I guess we should use the auto restart feature now? Could be useful in avoiding potential problems if the phone reboots automatically everyday.

Lol you are right. Damn

So far I only have to restart when my phone started to display "emergency calls only".

What's the screen on time? Did you use the phone all the time? Coz the graph is showing a consistent draining.

I'm adapting myself to fully utilise it too.
