I love my phone however I wished it would switch from 3g to LTE faster. I know which parts in my area have Sprint LTE by trial and error. My wife has an iPhone 5s and her phone switches to LTE as soon as she reaches an LTE area, however my LG G2 stays in 3G almost always...Sometimes my phone switches to LTE, but I find myself having to toggle airplane mode off and on to grab the LTE signal most of the time which is turning to be annoying. Perhaps this phone requires a really strong LTE signal or it needs some programming? or maybe the iPhone have a better chip? Is there a way to fix this, thanks in advance
I recently upgraded to Baja ROM from rooted JB stock and ever since have had problems switching to 3G from 4G. If I turn my phone on in a 3G area, 3G data works. However, if I travel to a 4G area and the phone connects to 4G, when I return to a 3G area, 3G data no longer works. The notification bar has a grey out 3G (wifi is off). Voice still works. I cannot get data again unless I either go back to a 4G area or reboot my phone. Turning on and off airplane mode doesn't help. Does anyone else have this problem? I have tried various modems, including NC4, NC2 and MJE. They don't seem to make any difference. Anybody have any suggestions? Thanks for you help in advance.
P.S. I live in Appalachian mountains where I am constantly roaming on Appalachian Wireless. They did partner up with Verizon to get 4G LTE so I suspect when I am on 4G, I am on Verizon network. I don't know if roaming makes any difference.
Hello Everyone --- Note3, NC2 Leak stock modded deodexed rom.....worked fine for several months.
Cell signal in my basement office is very weak -- got a VZW extender, 3G signal now shows super good strength and calls are good. I am on wifi for data... Problem is when I'm on the extender, the phone is laggy as ever...super slow, gets very warm, screen lags, experience is horrible. I have reflashed, cleared cache, everything.... to no avail. Once i unplug the extender...everything is just fine again (snappy/responsive, better battery life, etc etc)
Anybody else experience this behavior?
Is it a Booster or a microcell? Microcells/femtocells plug in your Home Internet where the boosters try to boost cell signals. Boosters generally only work worth a damn if set up very particular to the scenario at your location. Otherwise they get a ton of echo and your phone can hand off between the tower and booster which can lead to increased power use.
I hate boosters for the most part. They work best if you have virtually zero service indoors and can run a long coax outside to an antenna location that gets good service. Swapping the typically included omni antenna for a directional antenna and aiming it directly at the tower would be of much benefit.
Putting a booster into your house and expecting it to not suck is like expecting to find good food at Mcdonald's.
Also, you may consider that your Note3 may have reception issues that a number of people including me had when upgrading to KK. You should try to verify if the reception seems like it is behaving normally.
Lastly, use the app Advanced Signal Status to force your phone to CDMA auto (PRL). This will allow you prevent your phone from trying to find LTE, which will save battery and will operate cooler.
You can also force CDMA only, which will prevent your phone from connecting to EVDO as well as LTE, and should run cooler and save battery.
Note3 does not have separate radios for simultaneous CDMA data and voice. The ONLY way to have voice and data at the same time is to have 4G or wifi.
In your scenario, I would just put the phone into CDMA only mode at home and use wifi, and put it into CDMA/LTE auto (PRL) or CDMA auto (PRL) depending on whether you want 4G or 3G data while traveling.
Good luck
I am having a problem on my phone where I am frequently losing LTE - my phone goes to 4G and I have trouble with data.
If I turn Mobile Data off and back on it connects to LTE again.
This seems like it started happening after I updated to the GoldenEye ROM - before that I feel like my LTE coverage was a lot better and more consistent.
Can anyone advise me on how to diagnose and hopefully fix this issue?
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.
