Hello, I'm using oneplus one A0001, I'm having problem with 3g connectivity, my device majority of the time doesn't connects to 3g, and if sometimes it connects, signals drops. My sim is fine, coz i checked it with other device.
Does anyone know about this problem. Any help will be appreciated.
Thanks.

I have the same issue!
I use CM12 nightly from 20/12/2014 with stock kernel.
I found that rebooting the phone will help but I also have WiFi drops so go figure
I'm having issues with stock rom 11 4.4.4
My OnePlus One is on latest cyanogen 12.1, completely stock and unrooted. I am noticing high battery drain on cell stand by (42%)
and of that 52% of the time there is no connection to carrier.
Is there a fix for this issue? My wife's Note Edge (SM-N915G on stock KitKat) has no signal issues with T-Mobile. but my OnePlus One show no connection most of the time. Is this a CM12.1 issue or is this a known issue with OPO and T-Mobile combination?
Appreciate the help.
Which baseband?
This could just be because of where you're located. The OPO only supports one of T-Mobile's LTE bands, band 4, while the Galaxy Note Edge supports all three, including band 12, which has much greater range and building penetration.
All of the recent T-Mobile commercials touting improved coverage area and better building penetration are based off of using band 12 on their newer devices which support VOLTE (voice over LTE). All of their new towers incorporate this band in areas that previously had little or no coverage (especially rural and suburban).
If you're in an outlying area with poor band 4 coverage your handset will be constantly trying to lock in on the weak signal and shifting from 3G, 4G, and LTE. Doing this also greatly reduces data transmission speed and reduces battery life.
If you're in an urban area with strong signal acquisition, then forget what I just said, you have another issue.
Hope this helps.
i used OPO on tmobile and it worked fine, depends on many factors including location, time of day and of course the bands used by the device.

I see from your profile that you reside in the UK. The OP doesn't list his, so I'm operating under the assumption that he's here in the states. My observations and comments in the post above yours, are strictly based on what I know about this device and with T-Mobile USA, as I'm unfamiliar with its operations in other countries.

Apologies, should have included location detail. This OPO is in Austin, tx so its metro area.
Baseband: DI.3.0c6-00241-m8974aaaaanazm-1
Cynogen version: 12.1.1-YOG7DAS2K1
Kernel version: 3.4.67-cyanogenmod-g9220ae3
Build: LMY48Y
Will I get better luck on AT&T with OPO?

You might, but I can't say for sure. The OPO supports 2 of the 3 bands AT&T utilizes, band 4 (like T-Mobile) and band 17. So you have more of a chance. Bear in mind, that AT&T is considerably more expensive than T-Mobile and that they have roaming agreements with each other, where if you can't get any signal for telephony you'll roam off the other's network.
Generally speaking AT&T has more coverage, because it's an older more mature company with a more established infrastructure. T-Mobile is more of an upstart, but is rapidly expanding with a newer technology. Like I said in the previous post, explaining why your wife's Note got so much better reception, newer T-Mobile devices which support all 3 LTE bands (2,4, & 12) get better reception and probably twice the coverage than what is possible with the OPO.
I hope this helps explains things.

yes i do reside in the UK but bought my OPO in the US when i lived there back in 2013 and used it on Tmob. according to the website it works in the UK on Three and EE(tmobile/ orange). i use it on three and get 4g and 3g with no probs. i do like the tmobile usa plan of $40 unlimited all
Since stock 12.1 update, I've noticed mobile network keeps dropping and in return draining the battery quickly.
Thinking it's the update, I've installed custom 12.1 ROM, but the problem persisted.
With further searching, I've found fix here.

Goto APN settings, take note of current APN's.
Reset to defaults.
Copy previous APN values to currently selected APN.
Save then reboot phone.
If above doesn't work, try here.

Scroll down to LTE issues and try the method described. Just note that it suggest deleting other APN, but I recommend against it because it can interfere with roaming.

Thanks, so I am not the only one experiencing network connectivity issues. I do suspect this software related to some extent. Will try the fix and report back.

All phones can now get WiFi calling. Just download digits and sync it. Download it on your main driver and sync it. You can use the DIGITS to call using WiFi from any device using your number.

Hi
I have a Oneplus 6 8G/128G, upgraded to 9.0.4 through the standard OTA channel. Since I changed my telephone operator, from Vodafone to Wind3, I'm experiencing loss of GPS signal during phone call. If I change my SIM and plug a TIM or VODAFONE one, and I still stay in the same cell area, the GPS signal is correct.
The only way to have GPS working during call, is to force the phone in 2G mode only. If I set 2G/3G or 2G/3G/4G the problem occurs.
So it seems that there is a interoperability problem between GPS and the GSM cell, but this is a bug of the phone: it I put my WIND3 SIM in a different brand phone, it works.
Is someone experiencing the same problem?
Thanks
Stefano
Yup, same problem here. I fear it's hardware. I've had the problem for all the latest beta versions of Oxygen OS
I experienced that it happens in some area and not in other area.. Here where I live it works well, while where I was last week not at all. It seems something related with LTE which tricks the firmware of the phone in some way. If they do not solve, I think I will change my phone...
My gps works ok if you are on 4g or 2g network, even in airplane mode. But if the network drops to 3g network the gps gets unstable, I realized this by taking a road trip.
I suggest you take this test
Yes, I can confirm that it works in airplane mode and in 2G 3G 4G mode when I'm in my home location. In some other places it does not work.
And so?
Same problem here, also with new 9.0.4 or the old version of os . I hope for fix. (forse conviene segnalarla sul forum ufficiale)
Problem has been solved: Oneplus sold and Galaxy Note 8 bought. So here is the end of my experience with this Oneplus which, in the end, cannot be used for professional purposes but only for playing...
Same problem with 6T McLaren
I have the same problem, during phone call gps signal is going away, if I put in airplane mode GPS is working wll, so it's not necessary tho have Mobil network or wifi. phone is updated to the latest version of Android 9 beta. Contacting the italian support team the say that it's correct to work in this way, because during phone call connection drop to h and gps nedd 3G or 4G for working, it's a crazy answer because in offline mode gps works correctly.

I agree with you, this is a crazy and unacceptable answer. Unfortunately italian support teams are really bad in their job and with no technical skills (I have experienced the same with Samsung and Huawei service centers).
Anyway I think that there is a possible solution (at least with providers other than Wind-TRE): by enabling VoLTE in the service menu (https://forum.xda-developers.com/oneplus-6/how-to/guide-enable-volte-forcefully-activated-t3797538) some people reported that magically the GPS works correctly during phone call.
I was not able to let it work with my provider, Wind-TRE, because they have not VoLTE activated, but maybe if you have a different provider it worths a trial. I remember that when I had Vodafone as provider, the GPS always worked well and it started to fail once moved to Wind-TRE.
Let me know if it works!
After more tests I discovered that GPS signal is coming again after 4 minutes of call and continue to work, so this is a bug, no 4G or internet connection problem. Another problem is to contact OnePlus skilled support interface no one that admit that there is a problem, this is crazy!

I finally solved the problem i encountred with my mi mix 2s regarding LTE & 4G Bands and connection .
I just flashed a modem.img file extracted from the lasted rom posted on xiaomi.eu
https://xiaomi.eu/community/threads/9-3-28.49842/
i just used this command on fastboot
fastboot flash modem modem.img
After rebooting i got the LTE signal working correctly.
Just give it a try if you have the same problem
Thanks
Which baseband version do you have after that? Which network provider do you use? Thanks!
I have a Mi Mix 2S, M1803D5XA, 8/256GB model, bootloader unlocked, running Global Beta ROM 9.3.28 with baseband version AT4.0c2.6-303-0325_2303_ea9c837. The network operator is Telefonica/O2, the service provider is 1&1. LTE coverage mostly B20/800Mhz, rural area.
After losing 4/LTE connection, my phone does not reconnect automatically with the available 4G/LTE network (B20, 800 MHz). I have to change the default preferred network settings (LTE/TD-SCDMA/UMTS) to "LTE only" or "LTE/CDMA/UMTS (auto) PRL" and only then the phone reconnects to the available 4G/LTE network immediately. Rebooting/restarting the phone also helps to reconnect. So I think I have to restart the modem to trigger a reconnect. If I just put the phone on the windowsill and wait for it to reconnect the modem sometimes seems to "freeze". The phone indicates a 4G/LTE connection (four out of five reception bars), however, there is no internet connection. Again, rebooting/restarting the phone helps.
Also, if the phone has to switch from 4G/LTE to 3G or 2G it does not aggressively try to reconnect with "better" networks. "Upgrading" the connection to a 4G/LTE network takes quite some time.
I wonder why the default preferred network is "LTE/TD-SCDMA/UMTS" anyway because there is no TD-SCDMA network in Europe. I think it should be "LTE/CDMA/UMTS (auto) PRL", again, I don't know whether this is part of the problem or just irrelevant.
I noticed this issue mid-January-ish, I do not know whether it can be linked to the Mi Mix 2S' SAR value issue that was discovered by some French authorities ...
Thanks,
Lars
Being totally frustrated led me to reverting my Mi MIX 2S (M1803D5XA, 8/256GB model) back to the Chinese Beta ROM 9.4.12 yesterday evening, completely wiping the phone and locking the bootloader in the process.
Today, I've tested the "reconnectivity" a few times and surprisingly (?) the phone now works as expected, or at least much better. After completely losing the 4G/LTE connection inside a building (this was also expected) the phone immediately reconnected to the available 2G network and then to the available 4G network upon leaving the building with almost zero lag.
Chinese Beta 9.4.12 comes with baseband version AT4.0.c2.6-303-0409_2210_8fadd5d.

Same on my side - yet another updates and still no luck!
The only solution for now is to downgrade ROM to anything from 2018 because problem started in early 2019 ROMs
still not solved...
even some reported that the issue should not be there when using an custom aosp rom... but i had an calldrop/caller didn't hear me anymore today on my test drive with resurrection remix rom! as soon as i use another phone, tested huawei p30pro, galaxy s10+ or even the simple nokia 81104g i havent had an single issue with call dropping on the same route!
it also make me belive that after flashing ah new rom (after ah wipe) it looks like that it is working.. but after a day or a few days the problems start to appear?!
I believe I'm still having this issue whereas in certain areas I'm losing coverage and my phone won't regain services for a very long time. It's predominantly happening at home which is very frustrating. Has anyone found success in resolving this issue? I'm on Verizon and looking for any help possible.
Hello guy
I have updated my phone last week with android 11 official update.but some functions won't work any more
The important function is to force LTE app wont work any more.
When i use internet from the gsm providers some time when the antenna of 4g is far or weak the internet turned from 4g to h+ and that might drop the internet service.so i use force LTE to keep it at the 4g status.
Now the 3rd parties apps to force lte or force 4g doesn't work any more

That's something you have to write to app developer about and not here. Since we here cannot help you with that app, unless you want other suggestions on similar app that works on android 11?

I don't care about the app,all my concerns are about the functions that app was offering.so if there is alternatives that works with android 11 it's fine with me
