[Q] Mobile Data stays on with Wifi - LG Revolution

Anybody else experiencing this.. Wifi is on and connected but my 4G-LTE arrows are still showing and flashing as if it was transmitting and receiving.. but my Wifi is on??
I am using Launcher Pro instead of LG Home so I have access to the power widget in the Notification Bar but not the LG Home power controller.
I just installed Power Control Plus and it seems to shut off LTE and 3G when you press the 3G button and can keep it off with or without Wifi on.

I've noticed this. It doesn't bother me due to the fact that I have unlimited data. If it want for that it would bug the **** out of me.

As far as I know, on all the android phones I've had, u have to manually shut off mobile data even when connected to wifi. There are apps that include this option when making "profiles" that get triggered (tasker, CPU tuner) but otherwise I think it stays on unless manually turned off. Maybe its not using mobile data but it appears to stay "on".

On my olds droid the 3G would turn off when I got onto a wifi network. I might just be special. Lol

I have the same issue. It actually goes further, because when I manually turn off mobile data through the Settings menu the data icon still stays on. If I use a tool like Dataswitch the icon goes away, but I never had to do that with any of my other phones.
The other issue with wifi that I'm having is that if I set the Wifi sleep policy to turn off after 15 mins of inactivity it can't reconnect after it turns itself off. So when I start using the phone again it just keeps trying to obtain the IP address of the network without ever succeeding. I've tried this on multiple networks. I have to turn off wifi and then turn it back on. Anybody experience this?
These issues aren't big but they're starting to make me question the quality of the LG Revolution and I may exchange it for the Charge.

I have this issue too, and it is annoying. I'm not worried about exchanging it, because I'm sure this will be addressed in the port of CM7 that TheCubed is working on.

Do issues like these usually get fixed in a port of CM7? Do you think the issue of mobile data staying on when it should be off will get addressed as well?
Any idea when CM7 for the Revolution will be available?

i dont like this either because every other phone ive had that hides 3g 4g the wifi goes in the place of it but thats the only thing so far ive found that i dont like
2 from me,
1. Battery life is tough. I must have this phone charging whenever I am at my desk or It will be dead by 8pm. I would consider myself to be a power user. I'm coming from an Atrix 2 and would make it through the day with only charging in the car dock.
2. No true gps toggle. I use the toggle switchs all the time, all others work but GPS.
Otherwise I love the phone it's very quick and I'm loving ICS

Disable att smart wifi thing, your problem will go away.

The only problem I've had was with the screen sensitivity. It's no longer a problem. I fixed it with a Moshi Screen protector.
It's thick enough to balance out the touch screen and it covers up all the Logos on the phone.
Juice Defender can also cause wacky wifi performance issues. You can adjust the custom settings in Juice Defender to leave wifi alone.
Smart Actions hasn't caused any problems with waking up any of the radios or wifi.
Wifi works best if you disable anything that has to do with automatically connecting.
When you connect to your wireless point, just click "remember" when it asks you to save settings. That way it should connect/reconnect faster when you are within range because it's not scanning. It'll just connect.
Anyways, from a security stand point you do not want it to automatically connect to any open network. Wireless SSID can be spoofed with a name change, and connecting to open networks is asking for someone to record your activity, or even launch SSL strip to fish out information on the secure sites you visit. Packet sniffing at a Starbucks free WiFi is easier than using 'One-Click-Root.'
So just avoid open networks and disable anything to do with auto connecting. It'll speed up waking up WiFi and it'll make you much more secure.
If you still have wifi issues just toggle airplane mode on and off.

There's 8GB of space; how did 2 apps fill that? Go into setting>Storage and see what's really eating up your internal storage. I found that the camera by default saves pics/vids to the SDCard and I would bet that's what's killing your space. If so you can change the setting in the camera app and use the "Manage Internal Storage" to move over pics/vids that are currently on internal storage.
I've not had any wifi issues.
Having had this only 2 days, the only problem I've noticed is that there is noise when listening to music. Specifically using the standard Apple earphones and listening to Pandora. I also tried some other cheapo earphones and the same thing. I tried both earphones on my old 3g ipod and it was crystal clear. But this is really a nit-picky thing and I can only hear it on the lowest volume setting.
I get this notification asking for what keyboard input I want to use sometimes when I have the keyboard opened. I click it and it asks me what keyboard input I want to use. I have never installed any other keyboards and this has been happening ever since I got my phone a few days aho

Trying to get WiFi to stay connected at home

My D3 keeps disconnecting from WiFi on my home network. If I go into WiFi settings it instantly reconnects but I obviously don't want to have to do this every time I notice it has disconnected. Is there a setting somewhere on the D3 that controls this? I've looked but can't find any way to control this behavior. It does seem to stay connected when plugged in so perhaps I've got some power saving kicking in but I can't find a setting for that either. Any suggestions?

Wifi does not auto-connect when screen is off

I have a wifi issue that is a little different from other I have read here.
Issue: When my phone screen is off, it will NOT auto-connect to saved Wifi hotspots (eg, home, office) within range, until I wake up the phone (turn on the screen).
When it is connected to the Wifi hotspot, it will keep the connections even when the screen is off. (non issue)
I have set "Keep Wifi on during Sleep" to Always, and set "Sleep mode" to off. "Power Saver" is off too. Mobile data is off (I turn it on only when I need it). I checked battery usage, and Wifi is constantly on, just that it does not connected to the saved Wifi.
My question/issue is, is it normal for the One to not auto-connect to saved Wifi hotspots within range when the screen is off?
On my old HTC EVO 3D running ICS, it will automatically connect to the same hotspots without the need to wake up the phone (turn on the screen).
My One is still using the stock Rogers firmware (1.29.631.4)
UPDATE: I found that this appears to happen only when the screen has been off for a longer time (more than a couple hours). If I have waken the screen up an hour before it entered the saved wifi range, then it seems to auto-connect fine. Need more testings.

I do believe it is normal. It's to conserve power your phone would have to have a wakelock to connect to another network draining power. As I understand it the ONE puts the wifi into a power saving mode when it's not connected so it's not constantly draining your power while driving. Once you wake the screen it will then connect as it assumes you want it.

Should that be an option to turn that off, such as the "Wifi Sleep Policy" I saw from some other rom? Or the settings I mentioned above disable that behaviour already?

Don't think so. The wifi sleep would turn the wifi radio off which isn't happening. Oh quick thought check the network and make sure the phone is set to auto connect that would do it for sure!

So if I don't wake my screen, I will never get any sync when the screen is off and I just get back into wifi range?

As I have indicated in my first post, this has been set to "Always" already. Are you sure that works for you?
What is the phone not doing that you want it to do? Just turn on auto sync if you want your email and FB updates to be waiting for you. Or is that not working?
Quick test. Put your phone to sleep with gmail autosync push mail on. Turn off data and only enable WiFi. Then send yourself an email from a computer, if you get a notification on your phone while it is sleeping, then it is working. Or you can place a voip call with viber or send yourself a viber text from another phone.

It is not auto connecting to the saved Wifi networks when I go to work, or when I go home, with the screen off. I have to wake the phone (press the power button) and you can see that it will connect to the saved Wifi networks. The FB notifications and Whatsapp notifications are pushed, so they don't require auto-sync to be on.

If my phone is already connected to the Wifi networks, putting it to sleep will NOT disconnect it from the Wifi network. It only happens when I changed from one saved network to another (home to work, or work to home) with the screen off, then it will not auto-connect. I have tested that and I'm not getting the notification in that situations. I have to wake the phone up to trigger the auto-connect.

Is your wifi toggle always on? Or do you turn it off once you leave a certain network? The only way the device will auto connect to a saved network, is if the wifi toggle is already turned on before you go near a saved wifi network.
If you want a saved network to automatically turn on wifi and connect to a saved network, you will need some thing like juice defender. It teaches itself to know when you're near a saved wifi network and it will automatically turn on your wifi toggle on and connect to the saved network. Then once you leave the area or lock your device, it will automatically toggle off wifi and disconnect from the wifi network.

Not sure what you mean by "wifi toggle always on". My Wifi (under setting) on the phone is always on. I never turned it off. Under Power History, I can also see that Wifi is always on (un-interrupted blue bar).
I contacted HTC support, and they asked me to change the WiFi band frequency from "Auto" to "2.4GHz" and reboot the phone. It seems to have fixed the problem so far (after a couple days of testing). Although it would have been nice if they can fixed the problem properly.

Yeah, I just got the One almost a month ago and seriously thinking of returning it because of this issue. I wish I wouldn't have rooted it because since I did for some reason I can't get ADB to recognize my device. I've tried everything my noob brain can think of to fix it and the wifi issue but nothing works. I see that no other developers have a fix either as no apps or threads here give a solid solution.
I might give AT&T the money to warranty it and just get another device but I want that to be my last resort.
Personally, I think it might be an isolated hardware defect that was addressed with later devices which is why it is not as wide spread and therefore doesn't generate a need to find a workable solution.

No, I believe you have to be S-Off to do that, or else you need to flash the firmware. Have you trying reinstalling drivers or try on another computer to get ADB to recognise your phone?

[Q] wifi won't stay off after official 4.3 update (AT&T)

As the subject says. Some time after I turn wifi off, it would come back on again. My phone is stock, no root or mod at all. This only happens after the 4.3 OTA update. Anyone know what causes this or how to fix it? I manually turn off wifi when driving because it would otherwise pick up cable company hotspots along the way, which is very annoying and not useful at all. At work I keep wifi off because the company wifi has firewall, and signal in my office is very weak. I'd rather keep wifi off to save battery.
Anyone has idea/suggestion? I originally thought it might be the sensorly app, but I've removed that and the problem is still there. I turn the wifi off, and about 30 minutes later when I check the phone, it's on again! Very annoying...

Maybe check your Locate/GPS settings. There is an option you can select/deselect that allows HTC to turn on wifi for locate purposes even if you have wifi off. Maybe Contact HTC if this is a new issue caused by the update.

I have had the same thing happen,but only once or twice,I chalked it up to my home WiFi threw Comcast ,I've been having major problems with my Comcast modem dropping WiFi or to slow of a connection,think I have to replace the modem just been to lazy,but I have the smart network switch on in my phones wifi settings so I thought maybe from the signals switching so much it froze or something,but yea it did same thing I had no lte or 4G next to my carrier signal,the wifi was not allowing me to turn it on,or scan for networks,wasn't even showing any so I did the same thing hit the airplane toggle and it came back.

Sorry i have no others solution for it.
I just posted a thread about the EXACT SAME issue. It only seems to happen overnight, but when I wake up in the morning my wifi has been turned off and my 4G LTE isn't working. When I try and toggle wifi back on it gets stuck and never reconnects/turns on. My solution has been to restart the phone.
I'm thinking since this seems like a rare problem, that this is a device-specific issue. I'm going to try and exchange mine this weekend due to this problem and hopefully get a properly functioning GS5 instead.

Have the same issue (made a post about it already in this forum). Usually happens when there is a large fluctuation in signal. Grocery store where I get no service results in no service when I leave the store as well. Have to cycle airplane mode like you described.
WiFi hasn't done it yet.
Another forum member suggested it may happen if using an older style SIM, which I am (from my S3). I haven't been up to change it yet. What SIM are you guys using?
http://forum.xda-developers.com/showthread.php?t=2744472
I typically have this happen when I'm at home at night, while my phone is plugged in and on wifi. Just disconnects at some point overnight.
I'm using a brand new SIM provided by AT&T when I upgraded in store.
Very strange issue and is random. For instance, it didn't happen overnight last night.

My S5 just started dropping data randomly and causing my battery to drain with almost no usage... I tested using Skype in a good 4G LTE area and will start out with 4 bars and the 4G LTE icon but as soon as I try to initialize a test video call over Skype the signal immediately drops to either no bars at 4G or it will go straight to E!? I haven't had this issue in a long time and it just suddenly started. At first I figured maybe they lost a tower but now this is going on almost a full week. I've got unlimited Data so I know that's not the issue, it has a brand new SIM... I'm going to AT&T and see if they have an answer or if they'll swap it out. Annoying!
Also annoying that sending a simple text will fail... ugh no root and now no data! :what::banghead:

I've had this happen several times, but only at my work. Reception is poor at my office, and the company WiFi requires browser-based login each hour, which I switch to many times a day.
The phone basically stops using all radios EXCEPT bluetooth, showing a circle with a line through it. I've been rebooting the phone to restore connectivity, but will try toggling airplane mode next time. I haven't noted any strange battery drain.
I haven't seen this issue when wifi is disabled.
I didn't notice it locked up a few days ago and drove home where cell reception is very good. The phone didn't recover until I rebooted it.
I have a brand new SIM from ATT and use a Gear 2 (which is greatness, btw)
I've done the following:
1. disabled the damn ATT hotspot app
2. Disabled/enabled the Wifi connection check setting
3. Did a full factory reset
This is getting close to a deal breaker for me.
As an update...
I have this issue basically every work day with the aforementioned environmental variables
Today, I:
Disabled Bluetooth (left the gear at home)
Disabled wireless
Switched radio to 'LTE/GSM/CDMA Auto' with instructions in this thread
The radios haven't locked up and reception is much better.
I'll try leaving WiFi/BT on and use my Gear again next week.
For anyone who is still interested, changing the modem setting seems to have resolved the problem for me. It also improved connectivity in weak areas a good deal.
Unfortunately you must enter the key sequence to toggle the radio each time the phone is restarted.
