Got the galaxy s2 running XWKE7
Under wifi settings>advanced>Wifi sleep policy. selecting turn off wifi when screen is off setting does not seem to take effect.
Tested by pinging it and continues to ping even 5-10 mins after screen is turned off.
anybody else having the same issue ?
Have the same issue, want my wifi to turn off when the screen turns off but wifi stays connected.
Only thing I can think of is that i restored my access point with titanium.
Can this cause any problem and if it can, can I delete the restored settings?
My sleep policy works fine when turning screen off. When i turn on the screen, the wi-fi icon appears after a few seconds. Also the battery usage shows that wi-fi is off when screen is off and phone inactive. Might be related to one of your apps that conflicts with the wi-fi policy. Happened to me when using an app that had options to turn on/off wi-fi scanning.

Weird, will have to check this up.
But as far as I know I don't have any other app that manages wifi.
As you can see in my screenshot, wifi is on at all time even when sleep policy is set to sleep when screen off.
Currently I'm not connected to any wifi since I don´t have any in range at work but it looks exactly the same when I´m connected to my home network.

Hi, I have the opposite problem, I don't want my WF turns off when is sleeping. I remember that a program ask me to turn WiFi in energy save mode but I cannot remember which app and I have no clue how to go back...
Any help?
Tks a lot!

Have you tried setting the sleep policy to 'never'?
Has anyone found a solution to this problem? I did a factory reset (XXKI4) and it was still the same. Screen off, policy set to turn off when screen is off but I can still ping the phone after a few minutes.....?!?
EDIT: I remembered ;-) Had the same thing on my original Galaxy over a year ago.
Needed to edit a database:

Cant save sleep settings.....
I have a slightly stranger problem that's just started. I'm aware of the situation where wifi takes 15 mins to turn off after screen turns off was never bothered with that aspect.
However, since today I found wifi was staying on continuously - checked in settings & wifi sleep policy had reverted to 'never' - I always had it set to 'sleep when screen turns off'.
The problem now is that I change it to sleep when screen turns off' and 'save' this setting but it's not saving - when wifi goes off & then back on again or if I reboot phone, it reverts to 'never'.
Any ideas folks?
Back-up data and factory reset .
jje
Would like to know this too.
Wouldn't like to back up and reset everytime this happens.
Also couldn't find the files in /dbdata folder as indicated by the Galaxy S thread pointed to.
Is there any other solution?
someone says using static IP will solved this issue but It didn't...
Any news on that?

Me too! Any word on that?
Had the same problem, where the battery no longer lasted the whole day.
When I checked under "Settings/ Battery" and clicked on the graph I could see that whilst the phone was sleeping, WiFi was not.
I have done a few "factory resets." All seemed okay to start off with and then after a while I would notice the same problem.
This last time I found that "Google Now" is the culprit.
Just click on the blue Google Icon, under Applications, then bring up the menu, click on "Privacy and Accounts" then "Google Location Settings", then "Location Access" and make sure "Use wireless networks" is not checked. (also available from "Settings/ Location services")
That fixed it for me!!

Mine is not checked and its still keep 'on' for almost hour...
as far as I know its better to be on wifi instead of data, eat less battery... but anyway I guess its have its own wakelocks...
It's my understanding that the wifi on this phone has a very low power usage when inactive in standby. I'm going to guess, however, that the power usage goes up when it "wakes up" to scan for open and/or configured AP's. I'd also guess that it'd have to take the phone processor out of "sleep" and wakelock in order to perform that function
I'm wondering how often android (or this phone's default ROM in particular) will wake up to perform a scan of access points when it's NOT currently connected (but the wifi radio is left on at all times), and configured to only connected to known AP's.
Anyone?
Thanks

When the tablet is off (sleeping), my local DHCP server gets DHCP requests from the tablet every minute. The power led briefly lits when it wakes up.
When I switch the tablet on, the first thing it does is drop the WiFi connection and re-establishes it.
This seems higly illogical. Also, when I have networking applications running when I switch the tablet off, these apps crash or malfunction when I switch it on again.
Did I overlook a specific setting to avoid this?
I think that when you turn it on, the WiFi connection has already been dropped, but the indicator hasn't been updated yet. It then notices that the connection is down, updates the indicator, and re-connects. I'm not sure about the DHCP requests every minute. You can check in the System Monitor's Alarms tab what's waking your device that often; my guess is that the system figures it'll try to reconnect now that it's woken up, but it doesn't stay awake long enough to establish a useful connection.
I don't think there's really anything you can do to avoid this in general; it's just the way Android power management works. What you can do if you really want is to install an application that will hold a partial wake lock for you. As long as the wake lock is held, the device will never completely go to sleep; the screen will turn off (for a partial wake lock), but the network connection won't be dropped. Of course, this will consume much more power than letting your device sleep normally. I use this when I know I'm going to be intermittently using my tablet for a while (like when I'm cooking) and don't want to keep waiting for the network connection to come back up.

That could very well be the case.

Whenever I switch it on, there's always an alarm scheduled for Android System for the next minute.
Hi guys,
I own a Blackview Crown with the latest SW released (20141015).
I noticed that randomly during the day the audio profiles and the data settings for the dual SIM management are reset to the default values.
For example: I set "screen lock sound" and "vibrate on touch" to OFF and they are set to ON automatically by the system.
In contemporary the bug affects also the data connection settings on the DUAL SIM management menu... it is switched from one SIM card to the other one (and this is the most annoying problem...).
Do you know whether this can be a known problem? Or maybe this is an Android bug?
I already tried to write to Blackview.hk but received no answers so far...
Thanks a lot for your help!!
PS you know whether there is a LOG that can be activated to understand what is happening? this issue does not happen during system reboot... it happens really randomly, every 1-2 days
I found that the settings reset is caused by the Android "POWER SAVING MANAGEMENT" function.
When the "POWER SAVING MANAGEMENT" function is enabled many services are stopped to save power (like data connection or ringtone volume for example). When the "POWER SAVING MANAGEMENT" function is disabled, the settings are set at the default values (such as "high precision" GPS or "vibrate on touch"). The customized settings are lost.
I do not know whether this is a Crown-related issue or it's common to all the Android 4.4.2 users.
My Wi-Fi works in background (even when my phone is in Airplane (offline) mode) and drains battery. I checked Battery usage chart (Settings/Battery/Battery usage/History details) and saw that some proccess wake Wi-Fi after some time when phone is inactive and in Airplane mode. History details of Battery usage show that (after waking up) Wi-Fi stayed turned on even my power switch is disabled.
I have that problem since last update released in september. "Keep Wi-Fi on during sleep" option is disabled (choosed "Never (increases data usage)"). Also Viber's "Wi-Fi - sleep policy" option is disabled (choosed "Viber will use device's Wi-Fi sleep policy").
Can someone help me to solve this problem?
Phone model: Samsung Note 4 (N910C)

Anyone have similar problem?
