So i have a clean flashed EU ROM and i randomly lose mobile data connection (4G) for a few seconds and it then comes back. I don't lose the mobile network, but the 4G data sign just vanishes and then comes back again in a flash. This is really annoying especially while playing online games where 1 sec of internet disconnection is the difference between a win and a loss.
I'm on MIUI 11 EU ANDROID 10.

I am using Miui 11.0.4.0, my mobile data totally stop working yesterday. There is 3G, 4G and even Edge signal but no internet. Wipe cache/dalvik and change kernel doesn't work. Ended up I reinstall 11.0.4.0 and it works back again

I too dirty flashed the ROM again and it worked without any problems for sometime and then out of nowhere it started to do this again. I hope it doesn't affect you as well but it looks like it most probably will. :crying:
Might be this will be helpful. What I noticed in Stock Miui 11.0.4 when the wifi calling is ON then I noticed call drops. So I have turned off the wifi calling and using the VOLTE only and everything is fine. I think wifi calling technology is not yet stable enough to use. We need to wait for some more. So you may try this thing. Turn off wifi Calling and set data roaming to always and see if it fix the problem.

I did that on the first boot but to no Vail. Currently I downloaded the latest vendor from akhilnarang's website to see if it is a vendor problem. Everything I tried before has done nothing.

Are you on EU version like me or the stock global ?
I received the update last week on stock rom in EU. Since then severe problems with mobile data, it only works in cities where 4G+ is available. 4G, 3G and E don't work at all or only rarely.
Does someone have a solution to that? BTW also my camera is broken since the update. After every picture it says "processing HDR+" forever (even showing a notification for that that never disappears). My proximity sensor also has some problems... Never change a running system I guess.

There doesn't seem to be any fix (none that I know of until now). Till now I tried reflashing the ROM, installing the akhilnarang vendor and now I'm testing LTE band locking using network signal guru.
It might just be a placebo effect, but I think flashing the vendor somewhat reduced the problems with mobile data. You should give it a try and give feedback here.

Disable "Xiaomi Framework Service"
Same issue for me on a Xiaomi Mi9 Lite with xiaomi.eu rom.
After lots of workarounds tried I finally discovered the cause : "Xiaomi Service Framework".
It's a system app that resets mobile data connection when it detects or thinks there's no internet connection.
I use an intranet apn to connect to my company network, so my phone is not connected to internet when the apn is active and it was really annoying to have those data connection drops.
As I'm not using any Xiaomi Service (mi cloud and others) and my phone is rooted, the solution for me was to disable the app and problem solved!
Good luck

Hi there!
İve stumbled upon you post. Right now i have xiaomi Mi 9 with stock MİUİ 12.0.3
Since this update İ notice Losing mobile data connection randomly.
i randomly lose mobile data connection (4G) for a few seconds and it then comes back. the 4G data sign along antenna sign just vanishes (greys out) and then comes back again in a second.
İ suppose its very similar to your case. İts getting very frustrating
Have you by any chance got any workaround ?

Hmm.. authentication error occurs when the wifi password is wrong on your phone. If somebody changed the password on the modem also this can happen, and I don't know about avg but does it have 3g data management? And are you saying that Mobile Data is not working?
And FYI try a factory reset of your phone, it would most likely fix your problem.

i had the same problem . i just changed my wifi channel from 6 to 8 just do the same put your channel 5 or 7 or 8 and evrything will be fine if you dont know how to accesse your router just tell me my wifi connecting all the time without any error good luck
The solution that worked for me was to change the security settings on my router, from just WPA2 to WPA2/WPA. I had tried changing channels and frequencies, as well as my device name.
I've been having some issues that i wasn't having before. I've got the OPX for about a month now and it is connected through LTE but i can't access internet.
If i turn airplane mode on and then off, it works for about a minute or so, then stops to work.
Anyone experiencing this?

check apn's
APNs are there and they are well defined, I have manually redefined them now -> Airplane Mode on -> wait a few seconds -> Airplane mode Off -> surfed reddit for a minute or two, all of a sudden "This page cannot be displayed: 'ERR_TIMED_OUT' "
I would think this is a network problem, but there is a forum thread in oneplus forums where people are complaining about the same as me, although they associate the problem to Wifi and i don't
Also, i don't know if it's related, but I've flashed the latest version from MasterAwesome, the problems started there, i thought it was from the ROM, so i then flashed OOS2.1.3-x, where i had the same problem, then 2.1.2 and still the same issue...
I'm getting something like that issue but very rarely and mostly on WiFi. It comes between sleep and awake states so maybe check out greenify and see if that is the culprit. Or any other app that's restricting any function through the waking of the phone.
My oneplus x detects wifi very well, but does not connect to mobile data. What could be the problem?
Uh I have a similar issue but usually when I'm in motion. (in guessing switching between cell towers) what's your network. I'm using Tmobile US
Sent from my ONE E1005 using Tapatalk
Same problem I had yesterday. Must have tried 10 ROM's all of them flashed fine and everything worked except cellular data. I had no data what so ever. As soon as I flashed back to stock ROM data worked fine. So there must be a step or something we've missed in flashing custom ROM's spent all day yesterday trying to figure it out with no luck. Finally gave up and went back to stock. I'll wait for the official OTA marshmallow update from Oneplus
I'm having this issue right now with full 100% stock. Does any of you have the problem solved?
Just wiped data + cache + factory reset, but still no luck. I've also created a ticket on OnePlus support.

Are you using 2 SIMs? Data does not work for me on SIM 2 Slot but works fine on SIM 1.
I also can't connect to mobile data. There is no LATE/4G icon in the status bar but if I pull down the notification panel, LTE appears above the network icon. I've tried in both SIM slots. None of them work. The SIM card works fine on other phones.

Hi!
I did rooted my phone and unfortunatelly there is one problem...I lost my data connection. I have wifi and I can make calls but mobile data is just not working at all.
I have tried some methods...restart, sim out and back and restart, manually pick the provider and restart etc... nothing works.

Any suggestion for a solution how to get back my mobile internet connection?
Thank you in advance,

I had been using Resurrection remix 5.8.5 2017/10/17. The phone was working fine until some days earlier the battery percentage showed weird issues such as jumping 5-10% sometimes even 20% at once. So I took my battery to 0% and left it to charge through night. At morning I found my network had gone. So I restarted but the problem was there. I had backup of modem and efs files and restored that but after that the network keeps connecting and disconnecting in interval of seconds so rolled back to miui but the problem is still there. And now when I enable my data the network issues remains there and also my phone keeps locking frequently even if I am using. Suspectible apps that I had installed: substratum,Game Guardian,Lucky patcher,magisk and some of its modules. Any help anyone?

I flashed latest global developer fastboot rom through edl but the network tower blinking ie. disconnecting and reconnecting is still there. I cant find out what to do.
Also when the data is being used or if I call at the moment I get network the network remains stable and I can complete the calls and get message or use data I have never faced such weird issue.
Check network strength from about phone, it may be a network problem & happens frequently if you're on Jio.
Also, use VoLTE 4G sim in sim slot 1 & it's not a software problem.

Thanks mate but I think I got it right. What I did was removed the back cover of the phone unplugged some cables blew some air to clear out dust. And then reassembled and turned my phone on. And then after it turned on opened phone information *#*#4636#*#* and then finally put on the sim and voila the problem was gone. And restarted to check if the problem was gone or not and I am happy everything is OK. Anyway U are the best one for me Btw I don't know what caused the issue...
I'm on a pocophone f1 (64gb) running lineage os (android 9) and the latest version of magisk with no problems..... Almost.
I noticed that where I got 4g cell service, I get h+. No 4g (much less lte.)
Instead of saying "oh well" I decided to take to Google and tackle the issue. What I found is that sometimes you need to edit some things in the Mobile Network Options (this was the case on my old phone), well to my dismay I found that clicking on the Mobile Network Options did either of these or both.
-instantly take me back to the main settings screen with a "com.android.phone keeps stopping" message if attempted multiple times,
-stay on the same screen after I click it, the signal strength indicator in the notification bar/status bar will go blank for a couple seconds before redetecting my mobile network provider and go back to its h+ signal.
Please help I don't want to have to reset my phone unless it is the ONLY option, I already reinstalled magisk via twrp, I checked for lineage os updates and restarted my phone several times. I know that the pocophone's cell band works with my provider because I got 4g/lte before I put this custom rom on this.
(I am using Cricket Wireless BTW)
Thanks in advance.
Did you have a resolution that worked? I'm on Cricket in Virginia, US and was curious since I saw how few 4G bands it has.

I had returned to MiUi for a while but after a couple months decided to go back to lineage using the now updated firmware.
I'm still using it and it is working fine, the crashes in the settings were fixed, but I still only get h+ data. I switched preferred networks and in the busiest town near me (Jackson CA) I was able to get a tiny short lived sliver of LTE, before getting no signal at all. So I stuck with H+ because that was the only network I got reception on.
I understand that the pocophone has limited LTE signal in the US, but I used to be able to get 4g on MiUi. I'm planning on upgrading to the Mix 3, but I'd still like to get this resolved for future pocophone users.
Quick Update, I still have my good 'ol poco f1, still with h+ data, but I didnt really notice speed differences from 4g that much, but when I go to folsom, (where I go to college now), I get normal LTE.
I'm switching to a fairly new OS called POSP https://forum.xda-developers.com/poco-f1/development/rom-posp-v3-0-0-alpha-1-beryllium-t3965821 which brings android 10 to the poco f1, will report that later on in a different thread :3

POCO F1 has modified vendor image! if you are using lineage of 7-8-2019 (before it got reported and development stopped) , that version had its own vendor image making 400mb LOS to 700+mb LOS,
having said that!
you still need to flash firmware , use 9.6.27-9
https://mirror.akhilnarang.me/MIUI/beryllium/
now lets say you are on that firmware!
modified vendor creates strange Network issues and com.android.xxxx crashing notifications if YOU EVER HAVE/HAD used USB TETHERING on 3g network!
the modifited vendor dumps 3g log stats on /data/system/netstats which makes network configuration faulty and system UI keeps crashing restarting making mobile data also crash and restart
Perminant solution is NONE
temporary solution
1. avoid usb tethering on 3g
2. whenever such happens, put device on AIRPLAIN MODE and DELETE all the files in /data/system/netstats and REBOOT POCO

I tried to changed APN manually to rogers but still data does not work, only call and text works. Is there a solution to this? I believe i got Pro 2 (cn with global rom installed)
I had the same issue, below is the APN setting on Rogers website, I've found that if you make the following changes, it will connect to 4G data (until you restart your device)APN Type: replace "internet + mms" with "*"
MVNO: ROGERS
MVNO type: SPN
This will get you connected.
However, I ran into another problem after configuring the network this way. After restarting the device, the phone can no longer detect the SIM card, and has an error message prompting restart).
This is my problem after restarting:
Comparing with other phones, the auto detected APN Type is typically "default", but entering default will cause the connection issue right away. The "*" will allow you to run until device reboot.
I too would like help on how to resolve this. Seems more software than hardware problem since it only fails after boot.

I just tried your method looks like it works and as you said it doesn't work after reboot. However when I did "Network setting reset," I was able to connect to 4g again (but resets wifi passwords too). Hopefully there's a solution...
I noticed that this problem only happens if there is a SAVED wifi network WHEN the device BOOT up.
I did a factory reset, then enter the APN manually. I was able to connect to stable network.
I did a system restart, no issue. The phone reconnects to the network automatically after booting.
I connect to a wifi network. The phone still works fine.
I restart the device again, the problem comes back.
If I take out the SIM and only use the Wifi, the phone is also okay.
The only time when it doesn't work is when I have both, which is the normal use case.
Something is happening in the firmware between the wifi and the SIM during the boot sequence.
This problem exists on my Lenovo L70081, Legion Phone Duel 2 Pro, running OS 12.5.188 ST, updated using Rescue and Smart Assistant v5.8.0.25
Any help would be appreciated.

Im on the same OS version 12.5.188ST, my phone connected to data absolutely fine with no problems but after every few hours stop making or receiving calls. I did the following and its fine for some time now but I'm not sure whether this will work with every phone but no harm in trying :
settings.....cellular network and sim.....5G mode. By default (at least in my phone) it is on NSA, I first switched to NSA+SA but to no avail, than I switched to SA and vola problem solved, all incoming outgoing calls working bang on but I think now my phone doesn't go on 5g which is still not good but at least making calls as normal. Now, as I said, this procedure might not work for everyone but try it, cheers.

Was your OS able to read the APN from your SIM or did you have to enter the APN manually also?

I didn't mess about with apn, as I said in my earlier post I had no problems using data its always connected but I had problems with making and receiving calls, cheers
There's currently two ROM available on Rescue and Smart Assistant:
L70081_ROW_SECURE_USER_Q00017.0_R_ROW_12.5.188_ST_210819_qpst
L70081_EE_SECURE_USER_Q00017.0_R_ROW_12.5.137_ST_210710_sec_qpst
What's the difference between ROW and EE rom?
Which would work best in Canada and US?
is ROW only updated in Asia and Pacific?
i sort of had this same problem with Tmobile. it would only connect to 3g . if i connected to the 4g or 5g network i lost everything . i was able to fix it using my ROOTED phone and an app in the playstore called network guru. I used that to turn off majority of the network bands and only left the ones listed for the phone. My service was immediately fixed and havent had any trouble since

I know how ya feel, I pestered TMobile for 2 weeks and they were no help. They kept trying to push me off to Lenovo who was absolutely no help at all. Id go thru their website which connects you to Motorola. Then they would tell me they don't support the phone because it's Lenovo and give me a link to follow. Id follow that link which led me right back to Motorola lmfao.
After 4-5 times of going thru that nonsense I finally got someone who knew what they were doing. They told me because this phone was never released in the US I need to go thru their European server for assistance. Screw that, I did some more research and got the idea of trying this from some ancient post I found on xda lol.
It's actually very easy as long as your phone is rooted. download the app, click the 3 dots and go into force control. Then adjust the carrier bands so only the ones supported by the phone are selected. Then reboot your phone and it should kick over to a working signal . If not ya might have to monkey around in the service menu using the dial code *#*#4636#*#*
Here's a few screenshots to give ya an idea and a link to a website with all the bands listed. https://www.kimovil.com/en/frequency-checker/US/lenovo-legion-2-pro
