Hello,
I have installed several ROM since i received m'y lmx2.
And i play with several kernel and modem.
Some modem works better, more or less, but i use to have descent signal.
Yesterday, i try the India stock 19s cause i read good feedback about this ROM. But this ROM encrypts by defaut the phone and i notice bad data connection. So i did format data , and i perform a twrp restore of small eui.
This is when i have this weird issue :
I have 4g data, with pretty good signal (4/5 strengh) but the connection is very bad, no more than 20ko/s !!!!
I have two sim of different provider, and both have the same issue. Each show good LTE signal but the connexion is so bad
I try to reste apn, clean install several ROM ( small eui, cuoco, RR, AOSIP), whith several MoDem, but still have this connection problem.
I also test the data connection from different places...
I also fastboot erase modemst 1 and 2.
I also reset the apn.
And i eventually installed stock CN 23s ROM.
No success.
Well, i have no more idea. This problem starts since i installed the India 19s ROM.
It is the first time i meet this issue.
I dont think it is a hardware issue, cause the phone shows 4g or sometimes 3g signal depending where i am in my place, juste like before.
Fyi, The wifi works well.
Does anyone have an idea ? My phone is became unusable, cause i mainly use the phone when i am outside, with only data connection.
Thanks un advance for your help, i almost become crazy and desperate...:crying:
May be try changing the network type in *#*#4636#*#* service menu? first try it without 4g..
Thank you for answering,
I already try.
Actually, the phone show good LTE and 3g signal, but the real performance is very bad, like 2g connection. The download and browsing never go over 20 ko/s.
Really really weird. This morning, I go outside and I try the connection. Exactly the same problem, even from another antenna.

Hi guys. Me and my wife both have gs2 and we both are on tata docomo 3G network. The speeds are good and this phone is awesome, specially for someone coming from a blackberry like me. However there is a peculiar problem both of us are facing. The data xonnection sometimes hangs on 3G and does not move to h or h+, and in 3g therd is no data transfer. The data transfer happens only on h+. That means for all practical purposes there is no data transfer. Sometimes it alsi so happens that the phone is showing the h+ icon but again there is no data transfer and i cannot access any internet related app. In these cases when the data hangs the only option is to activate the flight mode and then again reconnect. Then the data works fine. Off late this has started happening a lot. I have tried a couple of things like deactivating h and h+ and working only on 3g but to no avail. Can anyone help with this. I have not been able to test on other networks so i cannot be sure whether this is a device related problem or due to the network. Any help would be highly appreciated.

I am also facing this exact issue. I am on Airtel (India) network. For me, it seems to happen when I am at some particular locations, and works smooth at some other locations.
I just deactivate data network mode and re-activate it (long press power) instead of flight mode, takes only 10-15 seconds.
Don't know if rooting and using custom roms will fix this issue, because I strongly believe it to be network-related. I used to have similar problems with HTC Desire with various sense/AOSP custom roms.
He y buddy. But if ur on airtel and i am on tata docomo and we both r having the same problem, maybe it is not a network problem and is rwlayed ro some handset setting. Did u try the *#302179# trick. Did it work for u. Same problem in othe networks and for some of them this trick worked.

And by the way thanks for the data connection mode trick ( long press). Atleast it is a better way to make it work.

i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.
Happening to me as well.
I always thought it was vodafone's poor network as my phone never downloads data when 3G is showing, it will only show upload arrow, then when it change's to H I get both uplaod and download arrows and starts working fine.
One thing I did notice though is when in Gran Canaria 3G was showing and working and data speed were ridiculously fast compared to here in the U.K
Surely this must be related to kernel used???
I have the same issue on my I9100 KI3, KF4, KG2 stock rom with either KG2, KF4, KI3 or KI4 modem. This is a combination of tower and our phone modem or kernel issue. I am having this issue with AT&T USA on KI3 and KI4 quite often in Champaign, IL. But when I went back to my country in Asia(Taiwan) 3 months ago, KI3 rom and modem have no 3G issue at all. I was on 3G 24/7 for 3 months without any issue there. However, I had the same 3G issue in Taiwan when I was on KF4 modem with KF4 rom when I first bought the phone. This is really a funny issue. I tried all the tricks and switching so many rom and modem, but 3g hang still happens to me with AT&T network. Now I am trying to lock the WCDMA band to 850 only, see whether it helps.
having the same issue here, but im quite sure its network related, inside my office the 3g dissapears at all and the same happends to a friend of mine who owns a SGS2 as well. whenever my outside the internet works as intended
also flashed trizillions of roms and modems before i gave up and blamed it on network rofl
I have my I9300 few months so far and never had any issue with it. I'm with three network in UK and used many different custom ROMs and KERNELS, but usually stick with OMEGA and PHENOMENAL. Few weeks ago I've found that internet on my phone slow down. Also in my place, where I always had H+ good signal I have now only H. After couple of tests (speednet) it shows that I can go up to 10mbit/s so it was more less OK for H but normally I had between 12-15mbits. I was still able to catch H+ in different locations, but my speed with H+ dropped down to 500kbit/s (download) and with upload it was no connection at all (still had full bar H+).
I've changed ROM, KERNEL, MODEMS, went back to original, done 100s wipes and still the same. I've cleaned the phone, reset flash counter and sent to three to fix. I've just collected it from the shop and have a letter that they replaced some hardware and it's fix, but I'm not happy with it - in my place I can only connect to H, not H+ (my wife's S3, same network has H+ all the time). When I have H+ in some places, download speed is up to 2-3mbit/s and upload 2mbits, so still way to slow.
Does anyone experience any similar problem? Should I send it back to 3 for a fix?
The other issue I have is with my memory card and I've seen it around, so it's not only me. Had 2-3 cards so far and with JB it keep saying 'SD Card Removed Unexpectedly' or 'Preparing SD Card' or even 'SD Card Damaged' when wake up from deep sleep. This was second issue I asked for repair when I've sent my phone back to three for a fix. Guess what? It's still the same, happen again as soon as I've put my card back in. It's not the card fault, because I've already checked 3 cards with the same result.
So, I had two serious issues (I think) and few hours ago collected phone from the shop as a 'fixed' and problems still exist. What do you suggest, should I send it back for a fix? How to deal with them? Maybe it's only me and I should live with my issues?
For the signal issue, have you done a signal test with the carrier? Usually they have them on their website you can test the signal strength in your area. As well as are you city or rurally based? Because that can be an effect.
Maybe it is you from a freak or rare problem. If you can live with it depends on how much it would affect what you do. If you're by Wifi for the majority of your browsing or data using time it shouldn't be a problem, but if you're out and use it then maybe it might be an issue.
The problem is that I've always had great signal in most places around Liverpool incl the one I live now and my work. Now I have only 'H' speed and in some places, where I catch 'H+' ironically speed is worse. Other people with the same phone and the same network still have H+ in full speed.
I don't care when I'm at home, like you said, can always switch wifi on. Problem is when I go somewhere and want to use internet. It makes different, everything net related is slow.
I don't understand only how come they gave me my phone back with 'repaired' note, where the faults are still the same... Probably they just wiped everything, flash it with new official system (which was there anyway when I've sent them the phone) and sent it back to me.
i suggest you take it back to maintenance, may be a hardware issue.
Thanks, will do it and fingers crossed this time someone will fix it.. This will be second time with the same issue, with third one I should get new phone
HI.
something very strange have been happening with my phone and my carrier's signal.
I have a GSM galaxy nexus running CM 11
for some reason, I can't have both a 3G data connection and my gps work at the same time.
I've tried lots of other combinations, (wifi on, wifi off, data on, data off, 2g only, airplane mode) and with all of them my GPS works perfectly.
the second I allow my phone to use the 3G connection, the GPS dies stops working completely until I reboot.
I've tried probably 6 different roms so far, including going back to stock and trying all the stock images google released for my phone.
then I decided to try another sim from another carrier, and guess what? GPS works perfectly, whether is 2G or 3G. so I'm thinking, is my carrier's 3G signal somehow messing with my phone's GPS?
I can't really find anything about this two things conflicting with each other. hope someone here knows a little more about it, or maybe give me a little hint as to what else could I try next?
thanks!
after trying pretty much everything, I bought a new sim card from my carrier and guess what? problem solved.. or so it seemed.
my GPS worked perfectly for about 2 days. then the exact same thing again. 3G enabled? no GPS.
I hope someone reads this and could help. I have no idea what to do anymore.
Hey guys,
I'm currently having problems with my mobile data. I was running stock 4.3 and flashed to CM 13 (I did a backup of course). My mobile data was working fine at that moment.
Since my the front glass was broken but the LCD was intact, I decided to send in the S3 for repair to a shop that fixes the glass but does not touch the LCD. I got the device back two weeks later and everything was good.
The problem started happening, when I put in my SIM card, I noticed, that 3G or H is not working at all (or very slow). Pages took a minute to just load the HTML. I thought that it was probably an issue with CM 13 or APNs and updated to the newest nightly. Still, not working there. I tried calling the phone and sending SMS and everything worked.
I then decided to go back to my backup of Stock because maybe CM13 was bugged. But now the 3G is not even working on my backup of stock. Regular G works, but is too slow to use. When I switch to 3G the connection is too slow and acts strange by switching to G or just losing the connection entirely.
I checked my APN and that didn't help.
Could that been cause by the repair? Maybe broken the antenna or something? But isn't it inside of the phone and shouldn't be touched by a front glass repair?
It's not an EFS problem I think, since I still have my IMEI and calling works, internet on G works as well but not on 3G.
If it's the antenna, how hard is it to repair?
Thanks for trying to help me!
This happened to me,
Internet will only work on
E, G, H, and H+
Internet will not work on
3G
Ask your carrier if they use Fast Dormancy, I turned off Fast Formancy and it's fine
Edit: do research if you wanna know more about Fast Dormancy
Thanks for the help, but unfortunately that doesn't work either.
I've witness another strange phenomenon where the mobile data is working a few meter away from my house but not near it. The strange thing is, it used to work and also works on other smartphones with the same carrier.
Aliens.. No seriously.. If you can get Hspda then there's nothing wrong. Your device has determined that the signal isn't strong enough to lock on so it chooses a stronger signal.

Hi there,
This issue is a weird one, but I also had it on my old OnePlus One.
So I travelled to London on Tuesday, and I noticed on the train ride that my signal kept dropping out, thats fairly common, as its fast moving and passes through signal black spots. The weird thing is, when I'd regain signal, it would show a full signal bar, and 4g logo, but had a cross next to it and said no internet access. If I rebooted my phone, it would then regain internet access again. I got the same issue just walking around London. Full signal bars, but no internet, and a reboot would bring back internet access. Airplane mode toggling didnt fix it. Im from the Midlands, so my theory is that maybe when my phone gets passed over from one signal mast to another, it causes an IP issue or something? I used to get the same issue when travelling up north too on my old phone.
Could this be an issue with Lineage or Lineage based OS's ? My OnePlus One did the same thing and that was running Lineage OS 14. On my Poco F1, im running crDroid which is Lineage OS based.
My only other theory is that maybe there is an issue with my SIM card? Im using the same SIM card which was in my One, in my Poco now.
The only common threads between the two phones is that they both have Lineage based OS's, and they are both using the same SIM card.
Does anyone have any suggestions?
Thanks!

You can confirm if it is related to LOS by flashing the stock ROM and checking.

have you tried setting radio to LTE/UMTS auto (PRL) ?
you have to do this every single time you boot your device.. set it for both radios, then disable radio and re-enable them / toggle flight mode on and then off..

Unfortunatly, im not planning on doing any travelling now for a while, so I cant really test it.

I'll give that a go and see if it works. I didnt realise there were so many network modes to choose from. I have a lot of modes in preferred network type settings too, ive got it set to 'GSM/WCDMA/LTE' at the moment.
I do have a private DNS set too(cloudflare 1.1.1.1), could that be causing the issue maybe?
I'll see if there are additional settings I should have on according to my network provider.
EDIT: Just checked, and my APN settings were on the wrong network, could explain the issues.
set it to an option with PRL, do not use the in-device settings page, as it is not suitable for global use (rather china oriented). use the hidden menu as suggested above.
also it's always good to replace an old sim.
APN is very likely a cause as well, especially when roaming.
I have noticed this the signal does appear to have issues.
I had same problem when I had mi a2 lite I found the signal not so great but this phone you would expect to be better then that one.
I use two sims both on different networks which also use different bands well on sim1 others phones max signal on 2g/3g/4g but on this one it doesnt want to drop below 4g and the 4g signal is all over the place at times its two bars.
now on to the other sim this network around my home has always had poor 4g so with other phones it would drop to 2g/3g which i would then get 4 signal bars not on this phone again tries to stay on 4g with no siginal and if you select option to choose different preferred network the signal on 2g/3g is 1-2 bars only.
i tried let/umts pri on one of the sims made no difference.
I have tried this outside my home as well same thing it's only when i am really close to a mast will i get max bars for both.
Hi mates,
My mobile POCO F1 not showing any signal strength, I tried doing factory reset but no go same issue. Could some one please help me.
