So i restored the OS to Jelly bean 4.1.2. with the hope that could work, but it doesn't, it still loses all the signal from the operator. I dont know what else to do.

[q] 3g very slow on samsung galaxy s2

Hi,
Just recently upgraded to the above phone on O2 but am finding the 3G internet extremely slow. My girlfriend got a HTC desire upgrade on O2 at the same time & her 3G internet is about 50 times quicker than mine !
Have fellows users experienced similiar problems ? Any ideas how to resolve ?
Thanks
I am wondering the exact same thing. I can't even get the facebook app to load, exept when I'm on a Wifi connection.
Does anybody know what could cause this problem?
Yeh I'm the same as well... Very, very frustrating.. even on full signal H+ it is almost like it isnt loading anything... do you think it might be the internet app itself??
Same problem here. On WiFi it works like a charm, but om 3G it's really slow. Even network coverage is low. On HTC its fine and I'm able to use the full 3G capacity I'm paying for but on my S2 it really sucks.
Any ideas?
Upgrade?
Have you tried upgrading your device? If not go to Settings>About phone>Software update?
I have a galaxy S2 with a 3 signal...speed looks alright not sure if it is slow in compared to others.
Let me know your Kernel version and Android Version

[Q] Jellybean 4.1.2 on SGH-i727r - lost LTE?

Hi there, I am sure someone here may have had this issue, but hoping for some help.
I am on the Rogers network, I have the Samsung Galaxy S2 LTE (SGH-i727r). I flashed the RC5, and the gapps RC4, everything ok other than the gapps did not load the gmail, google play books, etc. Not a biggie, I downloaded everything again.
My big issue is that I don't have any LTE. I do have an LTE plan, but I only got H+ & even then, it was spotty, usually stuck on 3G. Is this something that can be adjusted or am I stuck with it like this until ROgers comes out with an official jellybean release? I checked out the AT&T sites & it says that the skyrocket (which this ROM is designed for) does get LTE, but seems I am not getting it.
Any help is much appreciated, thanks a bunch for all the work on the release!

Try to set the APN to LTE or you could flash new radio

[Q] Galaxy S3 R530U 3G connectivity problem

Ok so im a noob to US cellular, but had a At&t S3 and many other phones and have done alot of rooting, custom roms, etc. installing, and never had this happen, I guess i'm trying to say the development for this phone isn't as high as the other bigger carriers. But I had multiple issues with several of the us cell roms for the s3 and last night i tried to put cm10 stable from the official website and afterwards now my phone only gets 4G lte, and the data works but when i go to send a message or call someone it doesn't work! When i go to mobile networks in more settings and switch to cdma only, i get the circle with the line through it or my phone roams non stop! As i know the 3G antenna or what not is the voice and texting part and the other antenna is the 4G lte one, so i think when i flashed either the cm10 or the k747 kernel one or the other screwed up that part of my phone? Has this happened to anyone else and if so could u find a solution? And yes i called us cell and they went through everything and said it must be hardware related, so idk if i have any other option but to send it in or do a warranty exchange. Please let me know if any of you have had this happen, I miss my phone and have never had this happen Thanks! Let me know if you need more info also!

[Q] anybody else having 4g connection issues?

About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.

[Q] Moto G XT1039 Signal loss problems on stock firmware

Hello! Apologies if I do some dumb mistakes forum-wise and pass as a total noon at this, cause I actually am! Anyway, here's my problem:
So a couple of weeks ago I tried CM12, an unnoficial CM12 by Beeto and CM11 by him too, I noticed a big major flaw with all of them, which made me go back to stock firmware... The cell signal sometimes is just very weak, and I'm experiencing this on the stock firmware too! I go look at battery>cell standby at the end of the day and I notice that it spends about 15% of time without signal, should this worry me? Its just that my friend's phones normally show "0%" or very very close in the same conditions! I'd like to know if there's a way to fix this in any way, either on the Roms I tried or the stock firmware (since I prefer custom Roms anyway)... I'll be waiting for a response! Thank you!
EDIT: My friends are reporting that my messages duplicate sometimes! Really need a fix for this, it's dumb :/
Also with an XT1039 here (rooted stock 4.4.4 w/ bb). Used a Samsung Galaxy Ace II before (CM11) and the signal has similar dropouts with both phones. Wondered if it was the firmware (on my old phone) but as far as I can tell (also tried my sim card with an old SonyEricsson V630) it is my service provider (E-Plus Germany). Moreover we have a pretty white (poor) provider coverage in Krautland (3G and LTE on E-Plus are basically only with full signal strength outdoors in major cities). So I guess nothing to worry about.
