[Q] Getting LTE icon sometimes while on wifi - T-Mobile Samsung Galaxy S6

Recently updated to OA8 5.1.1 and having a weird issue.
While connected to wifi every 20 seconds or so the 4g lte Icon shows up, sends a bit of data then turns off again. Turned off download booster, volte is off, the setting that lets 4g take over for bad wifi is also turned off. It doesn't seem to be using a lot of data but it has gone through 1 or 2 mb in the past few hours.
I also tried freezing the Caller ID app like suggested in a HTC One forum but that didn't help at all.
Anyone else getting this?

[Q] 4G/LTE issue, ARHD 4.6

Hello,
I have the following issue on ARHD 4.6, Plus network Poland. After booting or rebooting the 4G is always active, speeds are OK. After some 10-15 minutes of not using data connection, the phone switches to 3G and stays that way, when using data it goes to "H" (switching the airplane mode on and off doesn't help). I'would normally blame such things on the network, but every time I reboot the phone goes back to 4G and untill I keep using the data transfer, stays on 4G without any issues. Anyone else with same symptoms? You think I should push my network to solve this or is this rather radio related?
Thanks
Michal

[Q] Wifi and Data disconnecting during deep sleep

My HTC Butterfly S has been disconnecting from wifi whenever i leave it alone for some time (10~20mins). Whenever i on the screen after such times, i realise that there is ABSOLUTELY no data or wifi connection (only the signal bars icon are in the status bar) and 1 or 2 seconds later, LTE reconnected and then wifi reconnected 1~2 secs later itself too.
I tried sending links from chrome to my phone (using sendtab) during this period and the phone does not receive any notifications, thus confirming the fact that there is no internet connection whenever the phone is in deep sleep.
Oh and 1 more thing : this only happens when wifi is connected, if wifi isnt connected when the phone goes into deep sleep, there is still LTE connection. When wifi is connected and the phone goes into deep sleep, the phone does not default back to LTE or 3g, all forms of connection with the internet are gone, only leaving the cellular connection available.
Anyone having the same problems? Btw phone is bootloader unlocked and rooted, using stock rom.

Check and make sure your power saving mode isn't on

Nope it's not on, and wifi is also set to always on during sleep.
Probably it's how the Rom is built to save battery

Actually, I don't think that power saving mode disables the connection, but sleep mode, that is enabled on my phone in Power option. From description it disables any data transfer during deep sleep. I have MaximusHD rom, can't tell if that option is shown on stock.
Try disabling this option :
WIFI > Advanced > Wifi optimization
This option might be the cause. Also, you might want to tick the Best Wifi Performance to test.
It's natural for android to silently disable data when you're on wifi. It only makes sense to do that.

Data and Wifi completely drop, have to do airplane mode to turn it back on

I don't know why, but this is a consistent problem and it's getting annoying. I will only have bars, but no wifi or internet connection. This just randomly happens and I don't know what triggers it.
I have to turn airplane mode on and off to fix the problem. Is there something that is causing this?

This doesn't really help.
What happens is data and wifi disappear and if I hit wifi it won't turn on. I have to turn airplane mode on and off and it starts working again.

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.

[Q] LTE connection drops every 30 minutes

Hello!
I've been facing some problems with my LTE connection using TIM in Brazil. My 4G LTE speeds are great (about 50/50mbps) and the connection is pretty stable with about 40ms ping. I even use it to play online games in my computer, as it's faster than my home network. But recently after getting random disconnects when playing, I started to take notes of the time the connection was lost, and I found out that it disconnects every 30 min (the 4g icon also disappears and appears back in something about 3s). It didn't use to happen 1 or 2 months ago.
Wanted to know if that's a carrier-sided problem or it's my moto x, and if it's the second option, I also would like to know if there's something to bypass this half an hour limit (I believe it's some connection timeout).
Hope you guys can help me out!

My guess is carrier-side issue. Nothing you can do about it unless they do something on their end. They probably implemented a tcp or udp timeout of 1800 seconds (30 min).
Call and complain...
The problem I am having a similar problem on Verizon. I have to tap the airplane mode to get 4g back. It drains my battery searching for signal.

Sometimes I face this too... Mostly when I get home and it gets stuck in EDGE or HSDPA (I get a poor signal here because the tower is 7 floors above my apartment) and I can't get LTE back... I need to select GSM only or WDCMA only, wait for it to connect to the data network itself and then switch back to LTE. That's weird.
My cellphone wasn't doing this kind of thing before (timeout). I remember playing an entire match of League of Legends w/o further problems. Gonna try calling my carrier this week and see what's going on.

[Q] Why am seeing network signal strength & Cellular Radios on in Airplane Mode?

So I am using a Nexus 6 on the Latest Tmo build (28E?) of Stock Rom and Stock Kernel Rooted, Encrypted.
Since the update that enabled wifi-calling for the N6 I have taken to setting my phone to airplane mode and turning on Wifi only to save battery since the signal at my house bounces back and forth from LTE to 3G and that murders my battery. Most of the time the signal strength graph shows blank and battery app correctly shows the cellular radios as having no on time. However, after being idle for a while (it would seem) the graph begins to show the signal strength as Red (no signal) and the cellular standby shows up in battery usage with the radios as being on (with no signal) and "active for a few seconds". Toggling airplane mode on and off usually restores them to showing up as off. Other times I never notice and it stays on for a few hours and goes back off on it's own. My main concern is that it seems to be activating the radio on it's own, my minor concern would be that my battery monitor app shows that it's using the battery. What could be causing this? I don't think it's a reporting glitch, because it shows up in both the system battery panel and a 3rd party one. If anyone has any thoughts or could point me towards a tool that could help me figure out what's turning on the radio when it's supposed to be off, please let me know. I've included photos from today showing what I'm talking about, the phone has been in airplane mode the whole time in these photos.
Thanks so much!
Kev
I think your issue is one of the reason why I cannot get Wifi Calling working at all. No matter what I do, my phone is holding onto a cellular network. Still trying to figure this out.

The best I can tell, "Android OS" is the only thing that shows any mobile packets sent or received so it's got to be a system thing.
If you have the myT-mobile app installed try uninstalling it I found that app totally screwed with my Nexus 6, turning WiFi on when I had no desire to use it.

Unfortunately that's not the fix. I don't have that app installed. Tmo is sending me a new SIM as I am also randomly having Wifi calling drop in and out even while my wifi is connected.
Does anyone know any app that would let me see specifically what app is engaging the mobile radio?
