[Q] Where do I find WIFI sleep policy settings?

On ICS, where can I find the settings for Wifi sleep policy etc? My Wifi keeps turning itself off after a time, and Im trying to get the the bottom of it, but cant find where those settings would be. They certainly arent where they have been for previous Android versions...

Go to Wifi Networks, click menu bottom on bottom right > advanced.

Even though mine is set to always stay on, it regularly turns itself off. Every morning, I've lost quite a lot of battery and I have no connection. Within a few seconds of the screen coming back on, it will reconnect.
Is this just me? (Android Revolution HD 2.1.2)

Its not working for me. No matter what setting I put wifi on it turns itself off when out of range for a certain period of time (about thirty minutes I think). Driving me insane.

Mine's only a couple of meter's from the access point, still turns itself off...

The same for me. Not 30 minutes but immediately.
For example the notofications appear only if I unlock the screen.
In wifi setting is on "keep always"
Example: i receive a whatsapp, email or facebook notification only when unlock the screen. Is normal?
With data connection all work fine.

I'm glad to know it's not just me. At least that means hopefully there is a fix coming at some point...

same here anyone an idea? sucks hard..

I figured my problem, traced it back to the Vodafone app, it was causing wifi to crash. Once i removed it it works perfectly. The problem stemmed from the vodadone app constantly trying ro find free wifu points to.automatically connect to.

Battery Tips

Hello all. I just decided to retire my Vibrant yesterday and got an S3. I haven't changed much on it. I'll run it stock for quite a while. I am using a custom launcher, etc.
My battery life is horrible though! It's not even noon and I'm already down to 35%. I've made sure S Voice is not set to wake up when I talk to it. My weather was set to update every 15 minutes by default, but I've changed it to every hour. I charged it in the van on the way to take kiddos to school, and it was at 80ish percent. So that's quite a drop in not a long time. Granted, it's new, so I'm playing with it.
What tips can you give me to get the best battery life I can out of it? Besides custom ROMs. I'm not even rooted. Yet.

Well how long has your screen been on? That will be the determining factor in your battery life. Like you said, it is new and you are playing with it so I am willing to bet that probably has something to do with it.
Otherwise, turn data off when you aren't using it and keep the screen brightness as low as possible.

Here's what I do with a freshly flashed rom. I pretty much drill down through every setting turning off what I dont need.
WiFi - turn off network notification.
More Settings - Everything off
Sound - turn off everything below "System"
Display - Auto brightness off. Timeout 1min. Smart Stay off. Touch key always on or off. Auto Adj Screen Tone off. Battery% on.
Power Saving - Off.
Accounts and Sync - Off
Location Svcs - Off
Language and Input - Voice Cmd off. Voice Recognizer (all off for google and Samsung). Voice Search all off. TTS driving mode off.
Backup and Reset - can't remember what its listed under but below carrier data press to open and uncheck collect data (this is carrier iq, so I removed it asap once rooted)
Accessory - all off
Developer Options - set animation scales to 0.5x.
Hope that helps. I keep a lot off and only turn stuff on when I need it. There's some pretty cool features but for me it doesn't hurt my experiance with the phone to not use a lot of them.

Ah. My screen was set to stay on for 10 minutes. That, I would imagine, was a large part of my problem. At least according to my battery stats. Why do they set that as default??
My screen brightness is now set to low. What is this with the data? Doesn't that mean I would not receive email, google talk messages, etc?

I just did almost all of these. With the WiFi detection off, will I need to manually find my home network each time I get back home?
Also, if I turn Voice Command off, I won't be able to push the button and say "Listen to blah blah blah" or "Navigate to ....." correct?

I am on CM10 so I am not sure where it is for stock Touchwiz, but I would assume you could go to settings > display > screen timeout and change it there.
Yes, turning off data would mean no push email or Google Talk messages. You could download an app that turns off your data when you turn the screen off, then on when you turn the screen on and your emails and messages would come through then.

I should have also mentioned I turn off wifi and data when I don't need it to, which is rare but it happens at times!
By turning off the wifi notification, the only change is it won't give you a notification in status bar that there's an open network nearby that you could connect to. Itll still auto connect to any network you've already got configured.
For voice cmd, it won't let svoice open apps for you. But for example in navigation you can still hit the mic button on keyboard and speak your destination.

Can you upload a Screenshot of your battery screen... It will make it a lot easier to look at

On the Wifi issue. What I do with regards to wifi, is if I know that I am not going to be near an open connection, I turn it off. When I am at work, there is no wifi nearby that I can connect to. So I use Mobile Data instead. Why you ask? It is because when you have your wifi on, in the back ground it is always scanning for a signal. Turn that off and no scan, then no drain for something that you are not using at moment.
I know that this is a bit deeper than you wanted to go, but in the Build.Prop you can put a setting [wifi.supplicant_scan_interval=] and you can set that out. The time in there is the time duration on scanning intervals based on seconds. So the setting wifi.supplicant_scan_interval=180 means that it scans for wifi and doesn't find one, then counts off 180seconds and scans again.<--This is what I have mine set too, btw.

Disable the wifi when your not using it.

[Q] Disable "Searching for available network" pop up

I'm currently out of my coverage area so the "searching for available network?" alert keeps popping up every 10-30 seconds. This is driving me craxy, I've tried disabling all alerts and even enabling airplane mode. I can't seem to find anyone with this problem, so I'm assuming I'm just missing a simple solution. I'm currently rooted with stock rom on 4.1.2.

If there is no way to disable this pop up, is there some way I can at least make it think there is signal so it stops popping up? The alert has increased to every second. I can't even manage to type 2 words before the pop up blocks the screen and disables the keyboard.

That sounds annoying! Try this..
-Go to phone dialer and dial #*#*4636*#*#
-Select "Device Information"
-Scroll down and press the button "Turn off Radio"
Does that do the trick?

It was just a lil off that's why you didn't get the menu. But he was right! It's input this way *#*#4636#*#*
Most codes start with the star* first.

Thanks that works, but turning off the radio doesn't disable the pop up. I just connected to Rogers (I'm in CAN atm) and disabled roaming. So there's no pop ups while I'm their coverage. I still can't believe there's no way to disable that pop up.

Remove the Sim card! this will fix the problem

Simply remove the Sim card! This will fix the problem. When there is no sim card, the phone will not search for network, hence you will not get this error.
I simply removed the sim card, rebooted the phone, and tada, when I am flying on airplanes, and ofcourse there is not network coverage there, I can finally use the phone for games, music, etc, without this annoying message poping up every 30 seconds or so.

I have this EXACT same problem. I first noticed it after I turned on WiFi calling. This is not a mild annoyance. It's happening so often that it's rendering my phone nearly unusable. If anybody has any ideas I'd love to hear them. It also only started happening after I updated to Android 9.

I hated this so much on the S10, because it would interrupt games, apps, everything (and my network coverage sometimes flipped from 1 bar to 0, so I was seeing this 20-30 times a minute) but I found a solution that has worked for me so far (I've definitely seen my network transition to Emergency calls only without popping this up). Fair warning, I don't know what other consequences this had, but basically, I went to Settings -> Apps -> triple dot menu -> Special access -> Appear on top -> Show system apps -> (then I went through a bunch of apps that I thought could be the culprit, and turned them off. That included the phone apps). I've tested to make sure that if someone calls me I still get notifications (audio if phone volume isn't vibrate/mute, and full screen popup if I'm in another app). For completeness, I also went through the system apps in Settings-> Apps and turned all their notifications to silent and minimized, but as far as I can tell, that didn't help. I haven't gone back and turned stuff back on, because I never want to have this happen again.

[Q] Help: Physically can't turn of GPS on Note 4. Always on GPS only mode.

I have a new verizon Note 4. It's been a great phone with very few problems until recently. I can't turn off the GPS. I'm not talking about GPS running in the background of applications. I'm talking about in the Location settings I can't turn off the GPS. I slide the switch to the off position and it jumps right back to on. There's nothing I can do. I've taken the battery out, force stopped all the applications that access my GPS, and cleared my cache in the safe boot settings. Does anyone know why this is? Under "Locating Method" I can't change it to anything but "GPS only". Power Saving is grayed out and High accuracy will allow me to select it, but when I go back into settings it is back to GPS only. This isn't a huge problem, but it's concerning me that I can't decide when I want to have the GPS network disabled or not to save my battery.

You may end up having to do a factory reset. You could try downloading a toggle app and use it to try to turn off GPS.

HTC ONE M8 bluetooth wont turn on (Android 6.0)

Hi,
recently I started to use bluetooth because I bought a smart watch which requires bluetooth for smart notifications, ... Its been working great, until one day. Every time I didnt use smartwatch, I turned bluetooth off. And one day I tapped the icon to turn it on, and the bluetooth icon stayed pressed for a 5-6 seconds and then it went back white which means, it did not turn on. I tried everything, reboot, safe mod, recovery mode, force stop, ... Nothing worked. Then I did factory reset, which changed everything and bluetooth started to work again, but not for very long. After 2 days, exactly same thing happend and I have no idea what to do. Im pretty sure its a software problem, but no idea how to solve it. Please any ideas??
Thanks a lot.

Found this on another forum... I had the same problem and it got solved by following this.
What you need to do is clear the Bluetooth Share app cache and data, then perform a Network Settings Reset. I'd recommend doing it in that specific order.
First, open App Manager from Settings menu. Then use the three vertical dots on the top right to open the options. Select "Show System". Scroll to the Bluetooth Share app, and open up it's settings. Tap Storage. Tap Clear Cache, wait a moment, the cache will clear to 12.00KB. Now tap Clear Data.
Next, open the main Android settings again. Go to Backup & Reset, then Network Settings Reset. Tap Reset Settings and enter pin, if prompted. Tap Reset Settings one more time.
After that completes, which should be fairly instantly, try to turn on your Bluetooth. It should turn on! Yahoo! Let me know if this works for you!
