So, I keep my wifi on mostly at all times. But I've found that when I leave my home, and get outside my wifi range, instead of naturally switching back to 3G (I usually have 4G disabled for battery purposes, unless I need speed), my 3G and bars icon will be all greyed out, and I will have no incoming data. I otherwise have a great signal here in Boston. Sometimes it will eventually start working, but other times I will need to reboot in order to have a working data connection.
Is this an issue anyone else has? It seems the transition from wifi to mobile data is glitchy?
Just got a note 3 for tmo, currently my device is unrooted and fully stock. I noticed that my wifi being on, it works great but cell signal is near gone...sometimes even wont let a text get sent. as soon as i turn off wifi cell signal is perfect same as on my note 2 or that G2 i got rid of.
i noticed the following....
Wifi signal switching feature on or off, cell signal still is gone.
Wifi on, wifi calling on or off signal still suffers, in fact i even disabled wifi calling from the application manager for now. (never did like wifi calling)
Wifi on, make a phone call signal still stays low.
Wifi off, cell signal strong
Wifi off, make a call all is even better.
So, whats the deal? is there a fix? A search only came up with a thread about turning off the wifi switching thing in advanced features, but like i said it dont matter or work. any other search talks about wifi and it dropping and or about wifi calling dropping calls....
edit, i looked in the system setting, and noticed that the signal in my house right now says -90. turn wifi on, network says unknown from LTE, and sits at -90.
turn wifi off, network says LTE and signal still stayed at -90 (it did change a little but stayed at average of -90)
it seems as if the signal bars just dont show up with wifi on. like it cant walk and chew gum at the same time (cant show wifi bars and cellular signal bars at the same time)
what threw me off was when i couldnt send a text until i turned wifi off.
i also disabled wifi calling from my account level as well. didnt change anything.
do these phones need the sim that came in then box? my sim came from a note 2.
It is odd, but I have the same behavior. When I'm on WiFi, I have no bars for my mobile signal despite there being no change in the signal related parts of About Device->Status
So, no real answer, but you're not the only one seeing this.
Turn on Wi-Fi calling. Make a call to ur vm. End call. Go to setting click Wi-Fi calling and then connection preference. Then click prefer cell network. Wait 5 seconds then shut off Wi-Fi calling. Should be fixed
TWEAKED 2.0 NOTE 3
I have no idea why, but this worked. I already had the 'Prefer mobile network' option set and Wi-Fi calling disabled, but this little dance corrected the problem. Thanks for the tip!

amazing, i didnt make a call, all i did was turn wifi calling on, then off and all the sudden cell signal worked with wifi on. but for some reason, my phone app FC when i tried to look at the connection preferences. not that i care i dont use WIFI calling as it sounds like crap or is choppy for some reason. (well in the past it was) thanks! now i can actually use wifi!
I called someone the other day i had wifi on, and the person couldnt hear me half the time. next phone call was wifi off and everything worked perfectly. very odd bug, im shocked that it hasnt been corrected yet.

Only default text app (Hangouts or any from the Play Store can't) can send MMS and SMS through WIFI.
I'm using Darthstalker Note 3 V6 and Advanced Signal Status to switch between LTE or WCDMA. The problem I'm having is that sometimes when streaming data through Spotify or watching YouTube, WCDMA mode loses data connectivity. It usually happens after a prolonged period of use, but WCDMA just will just stop working not connect to 4G data anymore. I can still make phone calls and send texts, but internet and apps that rely on data just don't work. Signal strength shows normal, but the 4G is just dead, the indicator is not there either. However, if I'm in an LTE area I can switch to LTE and everything will be fine. Its like WCDMA just stops working for a few hours.
LTE coverage in my area isn't nearly as good as WCDMA and I prefer reliabiliy more than speed. Any help would be very much appreciated.
Switching airplane mode on/off - doesn't work
Turning the radio itself off through Advanced Signal Status - doesn't work
Reboot - doesn't work
Battery pull - doesn't work
I work in a building that has really bad connection to the data network. Whenever I unlock my phone, it always show full white bars but no indication of H or LTE, which means I am not getting data. It takes awhile before the phone then connects to the network again, albeit very slow.
Is my phone disconnecting from the data network when it is idle? When connection is weak? Is it trying to conserve battery from always trying to communicate with a weak signal? Anyway I can disable this delay to reconnect since I can still receive data but just slow?
i have a problem when my phone switches from wifi i will have bars but it will show a small x in the bars and i have to go into airplane mode for a few seconds then turn airplane mode off to get data working again... really annoying.
not sure if related, but the radio seems a bit wonky
I am using my new G7 Play with a Mint Mobile SIM (T-Mobile MVNO). I am seeing much worse battery performance than my G4 Play on T-Mobile prepaid SIM, even though its battery is several years old now. I tested the Mint SIM for half a day in the old phone, before I punched it down from micro to nano SIM size. I didn't notice any significantly different battery consumption during that time, but I didn't try to carefully test for an entire discharge cycle.
I have tried to configure them the same way, with the same basic apps and battery optimization settings. For reference, the G4 Play can last 5+ days with my light usage patterns. The G7 Play seems like it cannot even last for 1.5 days. The battery ran down over 25% overnight. In the same time period, my G4 Play only showed a 2% drop.
This is with WiFi on and in range for most of the hours in the day (at work or at home). Signed into GMail, Hangouts, and Slack. Location toggled off. Bluetooth toggled off. And OSMAnd+ installed from f-droid. One difference is that I am still using the default Moto launcher on the G7 Play. I replaced it with Nova Launcher on the G4 Play in order to get rid of the annoying Google search/assistant widget that was not removable in the Nougat update. Both have Moto Display and Moto Actions active, but all the gesture/camera actions are turned off. It just has the notification peeking and active display when you bump or pick up the locked phone.
I have disabled Google Music, Movies, News, and Drive to try to match the config on the G4 Play. I also am not logged in with Chrome nor Photos but those apps are not disabled. I am still searching the Android 9 settings menus, but I don't see any more things I can adjust for efficiency. The battery usage details does not seem to tell me why it is going down so fast.
I am not sure what else to try, except to blindly experiment with disabling other built-in apps/services. There seem to be many more in the G7 Play than on the G4 Play, but I don't want to accidentally cripple the phone. Another possible difference is the G7 Play is using the 5 GHz WiFi channels instead of only the 2 GHz channels. But would that explain such a difference in power draw?
Same problem here, single sim G7 play on t mobile. Tried running in safe mode for a few hours and the drain is the same. The issue seems to be running wifi and cellular radio at the same time. Wifi signal is strong, on 5 GHz. Running only on cellular reduces the drain significantly, even with my crappy -112 dbm signal. I am guessing this is some sort of bug - on a related note, if I turn on airplane mode, and then turn on wifi, the cellular radio also turns on, and cannot be turned off via *#*#4636#*#* diagnostics screen.
Current build is PPY29.105-36
Strange. I put my phone in airplane mode and then turned WiFi back on. It indicated that cellular data was off and showed no phone network status. I then turned on WiFi calling and it showed that I was on T-Mobile WiFi Calling in the lock screen status. I left it idle like this for 20 hours and the battery discharged from 100% to 93%. Today, I will try the opposite, turning off airplane mode and WiFi and using just the cellular network.
Before this test, I did play store updates, rebooted, and then fully charged the phone. There were updates to Phone and Google apps right before I rebooted. My Phone app is at version 31.0.241960258 and my Google app is at version 9.51.10.21.arm. My phone is on US Retail channel and build PPY29.105-36.
Did your cellular radio stay off the whole time? Mine will toggle back on right before my eyes. My google app is at version 9.51.8.21.arm, phone app is the same as yours.
It stays off. I'm only looking at the toggles in the pull-down status menu at the top of the phone screen. I also have bluetooth and location toggled off. Maybe you should try changing some of the location/background scanning options? I turned off those sorts of things when I first got the phone.
Yesterday, I rebooted, recharged, and tested the phone for about 8 hours w/o WiFi, but with phone and data service on. It used a lot more power than WiFi-only from the previous day. It was projecting about 2 days left when I interrupted the test.
Then, I toggled off cellular data service. For the next 9 hours, the power consumption graph flattened out a bit. It's down to 85% now bit it is projecting 3 days left instead of 2.
Ok, figured out the cellular radio turning back on, it was having wifi calling enabled, which doesn't seem to make sense, but I digress.
So you turned on wifi calling, and the power draw was still low? Can you check your cellular radio status with the wifi radio and wifi calling on with the *#*#4636#*#* diagnostics screen?
If I remember, I rebooted with wifi calling off, put it into airplane mode, turned wifi back on, then thought to enable wifi calling. It definitely did not show the cell antenna signal icon in status, and showed "T-Mobile WiFi Calling" in the lock screen. I tested it by calling the number from another phone, and it did ring.
Today, I have continued using the phone with cell modem on for calls and wifi on for internet (but cellular data toggled off and wifi calling still disabled since before last reboot). It is now down to 79% power after 25 hours of operation and predicting 4 more days at this rate. This is more like I expected originally, and not so far off from my old G4 Play.
I am pretty confused by the terrible behavior in the beginning. It may have something to do with booting up with WiFi calling enabled. Or it might be some other strange state that cleared after a few reboots?
If I remember, I'll try to put it back in the wifi-only mode next time I am back on my home network to check that status screen you mentioned. But, I am nearly sure it is going to indicate cellular modem OFF and wifi ON using 5 GHz band.
The phone info screen behind that dial code shows this regardless of whether I am in airplane mode or not: Voice Service: In Service; Mobile radio power: on; VoLTE Provisioned: on; Video Calling Provisioned: on; Wifi Calling Provisioned: on. Because of the differences in other fields and in power usage, I don't believe the indicator about radio power means anything here. The Settings->Phone Info->SIM status screen says "Mobile network state: Disconnected" and "Service status: Voice In Service/Data In Service" when I am in airplane mode w/ wifi calling active.
From the 4636 code phone info screen, these fields change:
- Airplane mode w/ wifi calling active: Signal Strength: -1 dBm 99 asu; Data Service: Disconnected; Voice Network Type: Unknown; Data Network Type: IWLAN.
- Cell on w/ wifi calling active: Signal Strength: -112 dBm 28 asu; Data Service: Disconnected; Voice Network Type: LTE; Data Network Type: IWLAN.
- Cell on w/ wifi calling disabled but wifi on: Signal Strength: -113 dBm 27 asu; Data Service: Disconnected; Voice Network Type: LTE; Data Network Type: LTE.
- Cell on w/ data on and wifi off: Signal Strengh: -110 dBm 24 asu; Data Service: Connected; Voice Network Type: LTE; Data Network Type: LTE.
And the IMS status screen further down under the three-dot menu changes:
- Airplane mode w/ wifi calling active: Voice over LTE: Unavailable; Voice over WiFi: Available.
- Cell on w/ wifi calling active: same as previous.
- Cell on w/ wifi calling disabled but wifi on: Voice over LTE: Available; Voice over WiFi: Unavailable.
- Cell on w/ data on and wifi off: same as previous.
It's only in the 4th config that I actually see "LTE" on the network signal icon in the phone status bar on the home screen.
I should also note that I set the wifi calling settings to wifi preferred/wifi for both choices.
Thanks for all of the troubleshooting info.
I guess this shoots down my simply both radios on theory. You still get bad drain when wifi and cell data are both on?
I gave it about 18 hours to find out. But no, it now seems to have little effect to turn on cell data and wifi together. The phone is continuing to have a pretty good standby power drain with WiFi, cell voice, and cell data turned on.
I'm down to 52% battery and it has been 3 days it was last charged. The power graph shows nearly the same slope over the last couple days whether I turned cell functions on or off. Where there were dips, I think it may be partly that I took the phone away from WiFi, so it started actually using LTE data, and also that I had the screen on some around those times to look at settings and respond to some texts etc.
I'll keep playing with it for a while, but I am also running out of ideas. What's frustrating is that the battery consumption info listed just cellular standby as the originall high power use, not some other app or OS function that would be easier to explain as software-caused.
Just about the only settings I have left to re-test are WiFi calling (with cell modem on), Bluetooth, and Location. I suspect that the location was on constantly in the first day because I wasn't used to the Pie status bar. In my G4P running Nougat, the location icon would be visible in the status bar whenever it is on. But on the G7P, it doesn't seem to indicate anything unless you open the drawer and look at its toggle state.
I worked my way all the way back to having everything toggled on... cell voice, cell data, wifi, wifi calling, and location. It dropped from 100% to 96% in 12 hours overnight, and estimates 10 days remaining. This is far different than the 20-25% drop I saw in the first days.
The only explanations I can think of for this whole experience so far:
1. The power use was due to application behaviour, but the usage details screens were not assigning blame correctly.
2. The battery charge estimates themselves were wildly incorrect in the first days.
3. The phone is configured to waste power out of the box, and has to "learn" to conserve power when idle.
So, the phone seems to do quite well now. I just hope it doesn't decide to switch back to its high consumption mode when I am depending on its battery to endure like it is right now...

We know that would be an issue for sure, but the question is whether that's the only issue. I'm hoping it is.
