[Q] Plug to recharge battery, wifi automatically on

Hi all,
i upgraded the dhd with the last ota 2.3.3 few days ago.
I noticed a strange behavior, perhaps a bug, when i plug my dhd to recharge battery to the AC-power, (not via the USB), automatically turning on the wifi.
It 's a problem only for my case? with 2.2.1 I had never happened.
Thanks to all

I think u have the setting for your wifi to work when the phone is charging, just go into the advanced wifi setting and change it hope that helps

i have, switch wifi to mobile data, never.
Is this the option?

No one has this strange problem too ?

Have you tried changing the setting to "always on when charging" and then back again? Sometimes that clears issues like this up for me.

I tried, "always on when charging" and now i have "never".
Btw this problem is present only with my work's wifi, because at home if i plug the usb cable to recharge it, wifi not turns on.
I havent wifi at home, but wifi not turns on to scan the networks near me.
EDIT: this problem is present only for favorite and configurated networks.

[Q] Nitro as WiFi Only phone

I am looking to buy the Nitro HD for WiFi only use and maybe occasional prepaid use. I will flash to some deodexed ROM or maybe CM9 so I am not so concerned about software issues in the stock ROM.
What I am more concerned about is - how are the cameras for Skype/Google Video etc?
Any way to turn off all radios except WiFi by default everytime the phone starts up?
Thanks.

^^bump^^

I'll chime in here, I use mine as a wifi only device. As far as Skype/google video goes, video calls are great. I don't have a Sim card in mine and the mobile settings are greyed out which I'm assuming the cellular is off.
I'm currently running the latest cm9 nightlies and the device keeps getting better and better.
Battery life is definitely better than gingerbread. Battery life is within reason for a device this powerful while on wifi. The only battery drain I've found is being out of range of a wifi area. It seems the device goes on over drive looking for wifi and within an hour, majority of your battery is dead. This might be a CM9 issue, I'm not sure on that. Just remember to turn off your wifi when out and about.

Thanks for the response. I got myself a used one for $200 today off Craigslist. Will put leaked ICS ROM on it
Looks much sweeter than my iPhone 4S!!

UP！UP!
The super screen is eye candy. Using wifi it will last for 5-7 hours, while using 3g only for 2-3 hours.
For these two reasons, i often use it only as WIFI.
Will somebody introduce a super airplane mode without shutdown of WIFI？

Get dx battery saver, put it into sleep mode, then activate wifi.

You don't need any special app. Just enable airplane mode, then enable wifi.

oh,no, it is a two-click thing with a wifi interruption.
We want a one-click button.

If there is /system/etc/settings.xml, modify it about what is airplane mode （this is, remove “wifi” in the lines of "airplane-mode" ）.

[Q] Wi-fi turning on and off randomly for anyone?

I was wondering if this was occurring for anyone especially when you turn on the screen and I can see that the wifi slider tab that indicates on/off turns on when I wake up the device. I also can't connect to any wi-fi networks since it just shuts off randomly within the minute or two that I connect to a network....
I am stock, rooted with Note2core kernel.

Me too
Yes, I just noticed this today, after having this phone for 2 days. I can start up a Wi-Fi connection to my home network, and after 3-4 minutes, it just drops off. Once it drops off wi-fi, it waits about 2 minutes and reconnects back to my home Wi-Fi.
Right now, I suspect that it might have something to do with power. Today is the first day that I have not charged the phone at all during the day. I am at 30% battery now. I started noticing the network shutoff this afternoon, I suspect when I was in the 50% battery range.
I put my phone on the charger to see if that might stop the wi-fi drop outs, but it hasn't yet.
I will tell you that I have done most of my fiddling using the Wi-Fi setup of the settings menu. As a check, I went in to the AT&T Smart Wi-Fi app and started my home Wi-Fi from there. My connection still dropped off after 4 minutes, but the AT&T app told me that my connection had gone into sleep mode.
I'm hoping that everything will return to normal in the morning after I get my battery back up in the 80%-90% range. I have been able to find any power setting that would cause the Wi-Fi to cycle like this.

Edited to add that I am stock, no roms or rooting.

From another thread... and it addressed the issue for me...
Delete all saved wifis.
Open the servicemode with
*#197328640#
Open the wifi menu via menu button and deactivate the energy saving mode.
Reconfigure your wifi.

ghicks, you are correct...
I tried this last night, and I have gone all night without a drop out, but I did sleep a couple of hours in there.
As a side note, I did have to reboot my phone after making this change.
Good luck

I had this issue until I froze the ATT smart wifi app with Titanium Backup. No problems since.

I also have not had this problem since I froze the ATT Smart Wifi app.
I figured it was some power saving option that I had not yet found, but I never saw it happen again after freezing all the bloat. Didn't think about it again until I saw this post.

Can someone tell me how to freeze the at&t smart wifi?

Doesn't seem that freezing the ATT app works (using Titanium Backup, selecting app, and freeze). And disabling WiFi energy saver in the engineering menu resets after a reboot...

A few of us in another thread have disabled our AT&T smart wifi app and have fixed our wifi disconnecting problem. We've done this by uninstalling any updates for the app and then disabling the app all through application manager in settings.

Thanks for the replies. It seems one can un install the smart wifi from the play store? I have not done it, but that option is available in play store.

This problem returned for me today. I have tried to use the code to reset the power save setting, but it isn't working for me.
I'm at 57% battery, and I just noticed this at around 65%.

Been about an hoursince my last update...
I turned off the energy saver mode in service mode. It dropped the wifi a couple of minutes after I did so. I verified that energy saver mode was still turned off in service mode.
I rebooted my phone, and I haven't dropped my Wi-Fi since. I went back in to service mode and verified that rebooting did restore energy saving mode to ON.
So, simply rebooting the phone is what helped me today. Since I am presently at 46% battery, it doesn't appear that battery levels alone are enough to kick this behavior in.
I don't know...

Turning off cell radio??

Is there any way to do this on this phone? Primarily for battery life issues? I plan on using this phone NOT as a phone lol, but I would still like to use BT and/or wifi without using the cell radio, hopefully saving some battery life.
Or should I just not worry about it and leave it all on? Phone isn't on a active network anymore, but still has all my old phone number info in it, etc.

Turning on Airplane Mode doesn't activate this? The RIL is still connected, but it shouldn't be broadcasting anything. Though you can turn wifi on and off while in Airplane Mode, just not the cell radio.

Well the issue is mainly with the BT. Once you turn on airplane mode, the BT is inactive. Wifi still functions, but I need BT as well.

No I can't. Maybe I am running too old of a rom? I know its a stock rom. GB I think.

I'm not sure if that's a hardware limitation with this chipset or not. I can do exactly what you described in my gs4, but am also unsuccessful on the incredible. Let me know what you figure out.

Assuming you are on 5.0.1 Lollipop, did you factory reset after the update? Many people have experienced problems after the update but have seen factory resets correct problems.
While on the wifi settings page (the screen where you find the list of wifi networks available), touch the three dots in the upper right corner and select Advanced.
Uncheck (turn off) the option to "Always allow scanning"
You can also turn off the first option of Network notification to stop it from trying to find open networks in range.
hope this helps.

Thanks for the response,
I am on 5.0.1, I did factory reset twice, Cleaned cache multiple times
"Always allow scanning" is already turned off
Network notification is also turned off (unchecked)
Funny thing is , I put the phone in Airplane mode (wifi off too) for a while and battery graph still shows WiFi on and phone awake

The Wifi thing is a lollipop bug.
It'll always show as on even when it's off.

That bug must not hit every lollipop phone because my wifi doesn't show as on all the time. When it's off, it's off.

Weird... mine does.
Are you running any special apps (like battery savers)? What Wifi settings are you using? Is Power Saving Mode on or off?
I'm curious now. But yeah, several Note 4 users on the non-ATT Note 4 thread are reporting this issue as well and so were many Nexus users.

No battery savers or apps designed to conserve battery; power saving modes off. All I did to wifi settings was turn off scanning and notification. I have a long list of apps that I disabled since I knew for sure I wasn't going to use them. I screenshot them below if you're interested.

Ok I was wrong. My phone doesn't show wifi always on. I kept wifi off all day and it showed correctly. BUT I think it did show as always awake on the previous Lollipop update. (I'm on COC4 now).
And btw, I have all the same apps turned off as you except Samsung Push Service because it seems to not sync S Note with my Samsung account (I have a Note tablet too) and Amazon because I use it.

Update
I did some further digging , based on the amount of battery used.
1. Cerberus App was using a lot of battery, so uninstalled and re-installed it... the Constant AWAKE problem is gone
waiting a few days to make sure that problem was really gone
2. Uninstalled "LLAMA" app and now WiFi does NOT show as always on

Having the exact same issue on my galaxy s6. Just turned on clash after picking up the phone and the resolution looks like as compared to my joke Moto X (2013). It's worst when zoomed way out and fine when zoomed way in. Maggie everywhere. What the **** supercell.
