Hey folks,
I've been running Nightly 102 for a few weeks now. I've noticed that about once or twice a week I'll get a random shutdown. No biggie, I just hold the power button for about 10 seconds and it turns back on. I don't remember this happening with 7.0.3 that I was running previous to 102.
Anybody know what might be causing this?
That sounds like SOD (sleep of death).
Basically, won't power on when should be in sleep.
Requires a hard restart (holding power down until it "turns off"), even though you don't see it "turn off." Then holding power again to turn it on.
Known issue, unknown cause? Active wifi has been thought to be a cause, but I've had it happen with wifi turned off. So no idea.

That sounds exactly like what I've been experiencing. Oh well. It doesn't seem to be hurting anything.
Well I get it at least once a day.
Sometimes, I notice it after charging my nook, it won't turn on even though I put it into sleep.
I've found that if I set "wifi sleep policy" to "Never", I get SOD. If I put it back to "When screen turns off", I have no issues - the SOD issue goes away.
This SOD issue only started (for me at least) when going from 7.0.3 stable to nightly 96 (or something like that-the nightly with the new kernel version). On 7.0.3 stable, i leave wifi sleep policy set to "Never" and I don't have any issues at all...
I would love to leave it set to "Never" so that it notifies me of incoming mail immediately....
thanks...
Even with my wifi set to turn off with screen turns off, I still get the SOD daily.
Now, I am on MIUI's Rom and have yet to have an SOD or freeze. So it's making me think it's a UI issue. Since MIUI is a skin over CM7.
I also have the same symptoms and it's probably SOD.
I was just wondering that is the difference between the two. The description seems to be the same in both but they are located in 2 difference places. Sleep Mode under Power in settings and Data Connection under Power Saver. If both are turned on is there any conflict or whatnot?

The power saver options turns off your data connection as soon as the screen is off then reconnects it when the screen is on. The one under power waits until your phone has been inactive for a while (6+ hours in my experience) and turns then turns the connection off. They won't conflict because enabling the one under power saver will naturally make the other one redundant.

Oh great! Thanks for the explanation. Okay so let's say power saver turns off your data when your screen is off, what happens to messaging services like what's app, viber and Facebook chat? I won't be notified of any of these when the screen is turned off on power saver mode?

Hi!
Having troubles with a 520 because once it enters the deep sleep state, it'll start getting Whatsapp notifications only when waking it up.
No battery saving setting is turned on.
An APP that wakes the device from time to time would help.
Thanks.
Perhaps you either have cellular data turned off, have no data signal, or are set to only receive notifications over WiFi? By default, WP turns off WiFi when the screen is off and the phone isn't plugged in. I think there might be an option to change that, but I don't recall where it would be.
There are definitely apps that will cause WiFi to stay on in the background (I think pretty much any streaming music app does this?), but those will wreck the battery life if you just leave them on all day. Apps are also able to periodically (~every 30 minutes) do some stuff in the background even in the phone is sleeping, but I'm not sure if this is allowed to wake up the WiFi and cause it to connect.
If the problem isn't WiFi instead of cellular data, I really don't know what's going on.
Thanks! Read here if you're still interested:

everytime when i charge my the phone, my wifi is turned off. I have to turn it back on, but it works fine. just wondering if there's a setting to leave it on.
Yeah it's in the advanced wifi settings. This is a setting that has been around on Android for a while.
check wifi control history, maybe there is some app that switches it off? Works fine on mine, are you using power saving mode?

i already checked the wifi always on in advanced wifi settings. there are no apps listed in wifi control history. and no on power saving mode.
any other suggestions? im pretty sure it's a setting related problem, but all the setting mentioned I checked. the always wifi is on, nothing in wifi control history
Hi,
Anyone else having this issue with their note 9? So when I have WiFi turned on overnight and when I wake up and I go out of WiFi range (WiFi is turned off), I realize my mobile data is turned off. I would have to go under settings > connections > data usage to turn mobile data back on. I'm not sure what the cause is and it seems to only happen after long WiFi usage (like overnight). The weird thing is it doesn't always happen. I'm not sure if it is a battery saving things or something is turning it off. Please help! Thanks
