When I first started using CM13 my signal went to roaming when I know I should have service. I have data roaming off and I've checked to make sure I'm not getting charged for roaming and I'm not. My phone works as it should and I can do everything I need still so I was hoping it would be fixed in one of the new updates. I am on the newest nightly build as of this morning and the R above my signal is still there, just wondering if anyone else is having this problem or know the cause?
I have the same issue on my Nexus 6
Same issue here. Nexus 6 Verizon, just switched to CM13 and I'm stuck on roaming - so far I've tried airplane mode for a minute or two, turning the data off and on, turning the phone off and on, and chatting with Verizon support in case they could do anything remotely. The one thing I haven't done though is try putting another sim card into my phone to see if I could divine any information that way.
Any help would be appreciated.
So after trying just about everything I decided to cave in and jump back to CM12. It was there that I noticed a key difference:
CM12's settings -> mobile network settings, has the following sub-options:
Data Roaming on/off
Preferred Network Type
Enhanced 4G LTE Mode on/off
System select
Access Point Names
CM13 (nightly #2) only has:
Data Roaming
Preferred Network Type
System Select
...while in all honesty I don't know what it all means except to say that it appears to be missing some features of the CM12 nightly I'm using on my Nexus 6 on Verizon. I guess I'll try back in a week or three to see if everything is working fine.
For whatever reason I had LTE pop up for like 2 seconds but went back to R and has stayed since..
I switched my parents over to Cricket from Verizon today. They both have S5's. I set the network mode to lte/wdcma/gsm but it keeps going from Edge, HSPA, and emergency calls only. So I thought I'd try setting it to WCDMA only well I can't as *#*#4636#*#* does NOT work.
While my LG G2 on cricket and my iPhone 7 on AT&T sit and hold both a steady HSPA or LTE perfectly fine without issue which is the reason I switched them.
Any suggestions? Would setting to global be better? I would assume it would make matters worse.
Both phones are running MM and I haven't really kept up with roms/root/etc for Samsung stuff.
Thanks
I picked up an unofficial build of cyanogenmod 12 recently and now I cant connect to data. Texts and calls work fine however. I tried doing airplane mode on/off but that did not seem to work. I also tried switching from 3g to lte in the wireless settings, that didnt work. I also tried using *#*#4636#*#* and tried changing the provider settings thing to CDMA (LTE) and that didnt work. I need help PLEASE. Nothing had worked thus far and my sprint data does not work at all. Please, does anyone have a solution?
Hi everyone. I decided to root my H918 from 10t by using lafsploit. At this time, my calls, LTE, and SMS were all working perfectly. After downgrading to 10p and unlocking bootloader, the device had difficulty staying connected to a single tower. it kept dropping signal often and was not able to make outgoing calls or stay connected to LTE for too long. After this I flashed LineageOS 15.1, not thinking much about it. On LineageOS, every time an outgoing call was made, it would drop the signal for about a minute. If no calls are made, LTE and SMS sort of work. I flashed 10u stock after that with Magisk and the phone has difficulty connecting to LTE or making calls/sending SMS. I have tried the following:
- Reboot
- Clean flash
- Format where you type "yes"
- APN settings
- Network mode change
- Airplane mode on/off
Somehow after a reboot (on Stock 10u zip) I'm able to make 1 or 2 calls and then it stops working. I called the carrier and they said there are no outages in my area.
I put my SIM in another TMO phone and it worked perfectly. I put their TMO sim in my phone and it had difficulties making calls. So the possibility of it being a sim issue is ruled out most probably. I have been recommended by a few people to try and flash an h918 modem but 1. Not sure if it is safe and 2. Not sure where to source it from. I have no other ideas and this is my primary phone so I'm having difficulties without a usable phone. Any suggestions would be hugely appreciated. Thank you.
Update: Tried flashing to 10p kdz from download mode but didnt solve anything.
Is the wifi also on?
I'm having the same problem, but was running on 10j. I went back to stock and upgraded to 10u to see if it fixes the signal problems I have with this phone. Both Cell signal and GPS on this lg v20 are horrible. On using the h918 on at&t. If not, i will either need to go back to my moto x pure or maybe buy the international note 9 with the unlocked bootloader.

The Wifi is on, but I also tried with the wifi off as well as turning off wifi calling, Volte, etc.

I tried the same. Just flashed a 10p kdz to see if that would fix it, but no luck. Same issue happening on complete stock OS..
I replaced my sim yesterday, but that didn't make any difference. Before that i replaced the plastic bits on the top and bottom of the phone where the antennae contacts with.
I went back to 10j yesterday which was still arb0 and now upgraded to 10u which is arb1. I'll miss lineage, but i was just having too many problems with it. Not sure what at&t has on band 30, that's the only band this phone is missing. I regularly was losing signal while just driving on the freeway.
Hello. I have the same issue on LineageOS. Been trying to fix it but no hope. But I did find a temporary solution. Let me describe the problem. I'm having a LTE sim that works just fine, then it just stop working. The problem is when you enter an arena without LTE or the LTE is too weak at that point then your cell signal is laggy and lost completely. But you can switch the Preffered Network Type in the Settings to WCDMA/GSM/CDMA and your cell signal is back. That's my solution for now. Hope It helps.
With a custom rom, you can't have wifi on with data on. Simply turning wifi off doesn't fix the problem. You would need to reboot. This has been a problem from the beginning. It works with a totally stock phone, but beyond that, no.
Here is the only way to keep data calls working properly: If you need wifi, turn on airplane mode, then turn on wifi. When you are done, turn off wifi, then turn off airplane mode to bring data back.
Not sure the signal is any better with the new firmware on 10u, but at least my location services is behaving better and the camera actually works in stock. I did a side by side comparison of the gps signal with my moto x pure. Side by side the moto x pure got to an accuracy of 10ft with 21 satellites in view. The lg v20 locked on much slower to 8 satellites with an accuracy of 50 ft.
For comparison -
satellite 14 signal strength
moto x pure 34
lg v20 23
the cell signal may be better with fewer drops, but in some places without lte the speed and throughput is miserable.
Even though the Moto G6 Plus has hardware support for VoLTE, Lenovo scumbags removed the feature from the stock firmware of my country (Brazilian retail), which is updated to Android 9.0. The stock ROM does have a toggle for turning VoLTE on/off, but it's broken, because when I make a call with 4G on, the "4G" icon turns into an "H+", aka 3G. My carrier where I live supports VoLTE, and it works just fine on my mom's Moto G5 Plus on Android 8.0. Is it possible to re-enable VoLTE on stock ROM with root access, or the only way to get VoLTE support back is flashing a custom ROM that has this feature implemented?
I am from the Netherlands, and I have the same issue... Does anyone have a fix. My moto has bootloader unlocked...
I was mistaken, the G6 Plus does have VoLTE support, what it doesn't is 4.5G/4G+. Go to Phone info menu by typing *#*#4636#*#* , and see if "VoLTE provisioned" toggle is on. Toggle it off and on in case it's already on but you still don't see the 4G icon, which tells that VoLTE is enabled.
