[Q]WiFi automatically turns on? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I need some help. My wifi just keeps randomly turning on throughout the day and its really annoying. I checked my settings and im pretty sure there is nothing that would do that but I could be wrong. Anyone had the same issue? Anyone know how to fix it?

I'm seeing this as well with a Bell Galaxy S4 (SGH-I337M). I have no idea what's causing it.

Ok. I think I *may* have figured it out.

Im using qualcomm battery guru and I went to the app to check my battery savings and I came across the manage wifi option. It basically says it will turn your wifi on and off based on your previous usage. Ill report back in a little wilhile to see if that fixed my issue.

I had this happen on mine and I think it was something to do with AT&T Smart Wifi. I don't remember though.

I don't use this app so I'm not sure if that's necessarily the issue, unless something similar is built into the Qualcomm chipset itself. It does seem to always enable itself at certain points of the day, I'm going to keep an eye out for a correlation.

So ever since disabling WiFi yesterday it hadn't turned on, and I thought it might have fixed itself. Today, I went the whole morning without WiFi and without touching the phone and when I looked at it later on it was enabled. I checked the battery stats and noticed that WiFi seemed to automatically enable itself the moment I woke up the screen to check a message a little while earlier.
I've also noticed that when this happens, it won't actually connect to my WiFi network when it's in range like it's not actually scanning for any networks. It also won't let me know of any open access points. If I disable and enable WiFI again, it connects like it should, or if I go into Settings -> Wireless, it'll scan for networks and connect fine as well.
It seems like this is a software bug that Samsung needs to address.

100% time without signal

Can anyone explain why I have 100% time without signal in cell standby. I used my phone all day sending texts and making calls. Also, the signal bar is constantly yellow on the battery graph. Should this be green?
Cheers

Yep. im on uk voda n have the same thing. this is my second sgs2 and both have had it even to i always have signal. cant believe theres so many bugs with gingerbread, come on google, sort your **** out!
Same thing here. I've found if you go into Settings> About Phone> Status it fixes it and will start to drop from 100%.

Confirmed. thanks. very random
Thanks confirmed that temporarily fixes the 100% The captivate did this as well when I had it but always showed 50 percent without signal and you could turn on airplane mode and turn it off to fix it. However that method doesn't seem to work for this but the about phone method does

Got my galaxy yesterday and I have this bug too. I was a little scared because on S1 it meant battery drain. When I woke up this morning I had 99% battery after 9 hours since charging. But I was still curious and thats why Im here.
Glad its nothing serious Hope it will go away when I finally choose a custom rom to flash...
EDIT: just noticed the last reply date, well sorry, found this thread through search. (Hey at least I didnt create a new thread asking the same thing!)

System UI frequent GPS?

Anybody else seeing that the system UI is frequently using GPS?? Approximately every 15 minutes
Why?
Can anybody confirm?

EDIT: I have noticed that this seems to only happen on LTE, therefore leading me to believe that this is related to the problem of Google Now not working on LTE/GSM.

Google Now uses the GPS to check your location if you let it. On my old phone too (AT&T Galaxy S II running AOKP JB) I noticed the same about every 10-15 minutes. I don't think it has to do with LTE though.

Not got the phone yet but does it still do this with lte disabled? Might be its not able to get position data from cell towers on lte so it defaults to GPS instead.

Yes sorry guys I corrected the original post, it's happening every 15 minutes approximately, but not just LTE, on WiFi, LTE, H+.. doesn't matter.
App running GPS is system UI

Think I might have figured this out. GPS data location when indoors (satellite's unavailable) is impaired with LTE on.
Can anybody confirm this problem?

Turn off the top two settings in Maps > Settings > Location settings and enjoy twice the battery life.

This doesn't solve the issue it only prevents data being used for GPS lock.
But yes if the problem exists it will stop the battery being drained

Wi-fi will not sleep when phone not in use....

I'm on stock 4.2.1 ROM and Franco r23.
I have my Wi-Fi policy set to "never", which should turn it off when the screen is off and the phone is sleeping.
But it's not doing that and I don't know why?
I use Better Battery Stats and an attaching a couple of screens so that someone can suggest why the Wi-Fi refuses to shut off and allow the phone to truly enter deep sleep. The second screen shot shows that Gmail is the top process in terms of battery usage, so I'm wondering if that's the culprit as gmail sync is always set on push, and can't be changed to any other schedule?
If so, this is a huge oversight by Google.

I have the same issue but worse.
Not only does my wifi not turn off no matter what the setting is, it does shut off my mobile connection.
When I turn on the phone after a long time period I see the mobile connection triangle blacked out and after a few seconds turns back on.
After that the issue continues even when the phone isn't in deep sleep. VERY ANNOYING
But no matter what the wifi is always alive.
Still not sure this isn;t a hardware problem and if it is I'm ruined because I don't live in the states.
Let me know if you find a solution, I'll do the same.
BTW I'm on 4.2.1 stock rom as well .
same here, wifi stays on, even if in deep sleep...

Other strange problem, when I manually disable WiFi, like 2 times in picture, data does not turn on. I have to switch 2G-3G and it connects or airplane.
This is not fair, finally after all those years waiting perfect andorid phone... like someone previously said Nexus 4 is like Bugatti, nice, fast and powerful but only for few miles.

[HOW-TO] Stop wifi from dropping

As many may have experienced, when connected to wifi after a few hours, WiFi stays on but disconnects from the access point for no reason. It seems to happen on the s6,s s5 and s4 on lollipop. Was I'm Howard forums and someone with an s4 posted something that may work.. Touchwiz has a wifi power safe option turned on. His will show how to turn it off.
Dial *#0011#
Then when the information screen shows up, hit "more" up top. Then hit wifi.
When the new screen comes up, just hit wifi powersave off to turn off the powersave feature. Haven't test for long. Let me know in the comments if it helps
Does nothing for me I'm afraid. Is this any different to the wifi setting "keep wifi on during sleep"?
Does also nothing for me...says wrong.. Mmh
Are you guys using the stock dialer?
I remember the code wasn't working with 3rd party dialer I was using before.

That is switch for the power save mode. It will disconnect wifi for a few seconds.
No noticable change for me, no bandwith or signal strenght increase on 5GHz
I see I'll try it the next few days and report back ☺

Haven't had the issue since. I'm not sure if it's a firmware thing but it should not turn off wifi. This is how is supposed to look
This setting destroyed my standby battery life.
It will disconnect wifi for a few seconds.

S6 Disconnect Problem
I had the same issue and solved it by changing my routers security from WPA2/Mixed Mode to WPA2 Personal. Since this change, it works fine on both 2.4 GHz and 5 GHz. Tried EVERYTHING else first
this is an extremely annoying bug....data usage has increased significantly because staying on wifi is such a pain, rather just use mobile data. i've heard about the security change, but that's something I can do at home, nothing I can do at work unless I somehow convince corporate IT to change their wireless settings? haha, fat chance.
i just want to know did the change the OP suggested actually work? No one has reported that it actually works other than that it killed their standby time. anyone?
Worked for me, fido galaxy s6 edge thanks

Stopping the newest OTA

Connected to WiFi today and my phone started downloading the update. Turned off wifi and it stopped at 25%
I would take this Ota but it prevents KitKat roll back. Is there anyway to stop it short of Permenantly staying on 4G?
Also, does anyone have the modem from the latest OTA?
Sent from my SM-N900V using XDA Free mobile app
The latest OTA is horrible. My note 3 won't get anything higher than 2 bars on 4G and it seems to lag a bit with performance. The battery went from almost 18 hours on a single charge with constant use to 4 hours... if I'm lucky. I've hard reset, discharged, recharged, and nothing replaces the battery drain. I think it's a con by Verizon to get Note3 users to buy a new phone. I don't recommend it, although they did supposedly patch for that silly MMS vulnerability going around. Sad times for Note 3 users... and getting worse.
