HTC Desire S Sleep Mode Problem

[BoomyBoy]

Hello everyone,

I'm using HTC Desire S (Android 2.3.3). I've been having a weird problem lately. When my screen goes off, I stop getting notifications after 10 minutes or so. I've never experienced such a problem before. My phone was running smoothly. I used to get notifications from Whatsapp even when my phone was on sleeping mode... I started not to get notifications from any application unless I turn the screen on and wait for 5 minutes or directly click on the application wait for it to establish connection with my mobile data. I guess my mobile data dies when my phone is on sleeping mode or something. I'm not sure though because my mobile data connection is always on but somehow applications lose connection with my mobile data until my phone wakes up. Can you help me with that? I've installed an application called Juice Defender awhile ago but I deleted it since it messed up my phone. I also tried to reset my phone but still no luck... Is there anything I can do?

Thanks

It seems no one knows the problem:D

Have you tried checking both of the following:

1. Always-on data: in settings, wireless & networks, mobile networks

2. Background data: in Accounts & Sync.

Make sure they're both on.

If that fails, I'd just recommend backing up anything you want to keep and doing a factory reset.
