[Q] Weird 3G issue since jellybean - Galaxy S II Q&A, Help & Troubleshooting

Hi Guys,
I've been an active "reader" of the forum, but never really wrote anything until now.
I've noticed that ever since I flashed my rom to Jellybean (specifically super nexus 1 build 5 and super nexus 2 build 2), my 3G connection seems to disconnect rather frequently. For example, when i open my facebook app, it says "cannot connect to server" and I have to refresh it for it to work. This problem disappears when I connect to wifi. This is weird because every time I flash a rom I do a full data/factory reset and wipe cache and no one with my rom appears to be having this issue. I never had this issue when I was using gingerbread.
I am using the default CM kernel that comes with it
Can you guys tell me what might be an issue and how I can solve it? I know its a small issue, but it just annoys me sometimes.

Flash different modem.

[Q] May Need A Jedi or Moderator Help for this Internet Question

Hey people need your help in regards to an internet/phone issue which has me stumped.
Ive recently flashed a couple of ROMs just to see what they were like and since then have had issues in regards to not being able to connect to the web...well not being able to 99% of the time.
(This is where i need a Jedi MAster)
Ive flashed about 30 ROMs onto my SII with no problems as of today!
Ok first, the two ROMS i flashed were Rarity and then Turkbeyv's, did full factory reset on both, wiped all data from cache and Dalvik and then formatted memory card just to be sure.
I then went back to Criskelo's v30 then updated to v31 as it was uploaded and i thought this may rectify the problems ive been having.
Disc: THIS IS BY NO MEANS ME BLAMING THE MENTIONED ROMS FOR THE ISSUES IM HAVING,ALL OF WHICH I THOUGHT WERE OUTSTANDING,i just cant help but be a Flashing addict lol
PLEASE REFER TO INCLUDED PIC:
A - cant seem to clear this battery image,informing of full charge,battery percentages always stay high on top right indicator then suddenly drops to low percentage.
B - Am showing HSDPA but unable to connect to the web using default browser, firefox although can conect using Dophin HD, first time i managed a connection via Dolphin which again is probably once in 10 times of trying, when i managed a connection it was pittifully slow,worse than EDGE (yes im that old).
I knew i had a problem with the connection when tryin to log into my google account,using the other mentioned ROMs, it just wont let me, unless im using WIFI.
All web based apps from Facebook, Google and the Market simply wont connect to the server,as for all other connected apps the ou come is the same...
C - The other issue i have is apps appearing and then disapearing or saying uninstalled.
Having finally managing a connection using Dolphin HD i noticed an icon had been placed on my homescreen?
also having problems with contacts, ive been using AContacts from the market and when i use the default contact app, they both force close stating "android.process.acore" error, any ideas?
SOooo these are my issues people, thanks in advance for any help given, please note that im not a coder but can follow step by step instructions if given.
I hope to hear from you all shortly

Loss of WiFi connectivity

I bought a Samsung Galaxy S III while on vacation. I didn't really want a US model, since I already had a Galaxy S II and the only compelling reason I would upgrade was for the quad core Exynos.
Well here I am back States-side, and it's been working fine for a week or two. Last night I suddenly lost the ability to connect to WiFi networks.
Basically I can search for a connection, it will show up and say it's "Saved," but it will not connect, even if I manually choose the option. If I choose "Forget" and reconnect, it will connect briefly for a few seconds and promptly disconnect again.
I've tried the usual steps of rebooting, checking my network, etc. I've gone as far as reflashing the firmware which doesn't seem to fix my issue.
I have several other devices and none of those have issues connecting to my wireless network. I've tried a couple different AP products, including an Apple Airport Extreme, a Linksys WRT-600N, and a bunch of really old APs with a different chipset manufacturers, none which seem to work.
For OS, it's currently on Android 4.0.4 with the stock Samsung TouchWiz interface, no carrier customization.
Since returning/warranty for this device is out of the question, I am looking for a possible solution to my issue. I am not a big Android user. I used to be big on Symbian, and now I'm mainly an iPhone user. I have an Android phone to keep up with the times, so to speak. Is it possible I'm missing something? Could I have changed a setting that would cause my wireless issues?
Thanks!
(Tried searching this topic, didn't turn anything up)
I'm having the same problem too. Everything connects except for the S3. If I reboot the router it works for a day or so then the problem re occurs.
If you get disconnected meaning there's interference in the frequency range, you could change the channel so it doesn't overlap with your neighbors' or your other APs, remember any AP operating on the same channel or nearby channels in range is likely to cause signal to interfere with another AP's wifi signal.

I had similar problem. A factory reset fixed it.

I tried another factory reset and I'm still experiencing this issue. I'm a bit bummed out at the moment. I can't connect to other networks either. At least I have cellular data to work with for the time being, but I expect I'll get throttled sooner or later.

I don't think it's an interference issue.
Like I said, none of the other devices have connectivity issues. I haven't really changed my wireless setup for the last 10 years. Always the same channels (with difference channels for each overlapping AP—channels 1, 6, and 11). My cordless phones all use DECT which runs on 1.9GHz and I usually have Bluetooth off when at home. As for neighbors, the distance between our homes are far enough I am never really in range of their networks.
If enabled, turn off power saving
same problem as yours. i've replaced the kernel and still testing.
I have this problem, i think it's hardware problem, just updated the f/w hasn't made it better.
Try adding your wifi manually and select correct security protocol....it resolved an issue like this on my iphone4s.

it doesn't work for the SGS3, it's a known problem, i've checked a few sgs3 and some have this problem including mine, i'm changing my unit tmr.
Has there been any temp fix for this? I've been noticing this a lot more when using WhatsApp, usually you can see the last time your contact has been on, but it only shows if there is a current connection to the internet. When I'm connected to the wireless, it'll show up but after a while, I assume the wireless loses connectivity (sort of) and it won't show the last time they were on. The thing is though, I'm able to get to any pages like normal, so it doesn't actually lose connection.
Why don't you flash a better rom~~

Braking connection via WiFi and freeze on lockscreen caused by WiFi

Hello,
I became a proud owner of S3. As it usually happens to me there is the problem. Namely, from time to time problem happens to me when I'm using any web browser or anything that requires an Internet connection. Say for example Opera. I'm browsing pages and suddenly ... BOOM ... 3-5 second pause in the connection over WiFi (energy saving is off and in WiFi settings - I did it via code, in the service menu). Sometimes Internet connection breaks when I'm browsing menu or writing an SMS. For example: I browse the menu and suddenly I see - WiFi stamp disappears and after a while there is info about that phone is connected again. This is the first problem.
The phone is lying, WiFi operates in the background. When I Pick up the phone and when I'm clicking home (or power) button I get the lock screen and. .. freeze. Phone is disconnected from WiFi and only time the phone reconnects to WiFi I can unlock the screen.
On what ROM were the problems? On the Stock LF2, ROOTed LF2, Omega 7.1 - 9.0 and AOKP Milestone6.
And also it does not work automatic refresh of weather (at 1 h interval) on stock widget (the Samsung weather widget).
Sorry for my bad English.
Why couldn't you have just set your wifi to never turn off in settings, wifi, advanced.....it's practically the same thing....I wouldn't be messing around with the service menu. I would wipe data/factory reset and start again bud but this time, stay away from the service menu as it's for technicians and phone repairs etc I've not once touched the service menu....

I found the same problem ever since I upgraded to LH3 (the latest official release at this moment). The lock screen is frozen if: I had the WiFi Switched On, screen off either manually or timeout, then disconnected (say if I walk away from the wifi service area). When I press Power or Home button to wake the device, the lock screen is frozen.
Seems no freeze if wifi remains connected. Seems no freeze if wifi power saving mode is off (disabled via *#0011# (but setting won't stay if unit is power off).
Did both Cache wipe (didn't do factory reset) but makes no difference. Tried "never turn off" also makes no difference (probably because it will turn off anyway when connection is dropped)
The upgrade seems worser than before...
Any hints please...
This seems to be common but not always the same fix, my wifi constantly drops out and reconnects immediately (ruining any downloads/streaming) , i have tried the service mode, factory reset, different kernels, sleep time, static IP's, JB vs ICS Roms / Stock roms, you name it i have tried it and it STILL is doing it. Weird thing is..dont think it dropped out and reconnected when i was stock and unrooted, but as i said, tried stock rom and to no avail
Any ideas?
Bump

Hi, I am having the same problem again after not having this problem for a month or 6.
I qas having this problem on my note when on gb and now on cm10.1 but the problem never occured in an custom ics or jb rom.
So I recommend; use a custom ics or jb rom to solve this problem
Cheers,

I have this issue on my galaxy note N7000, and only recently for like a month now and on various different ROMs all JB. Any updates on what the cause could be?
Go full unrooted stock and send the phone in for warranty repair. It's the smartest thing to do if a problem persists after lots of ROM switching and factory resetting.

That's would be the smartest thing to do, indeed. But... Warranty expired centuries ago.
Any clue what is causing this not uncommon problem?

Try visiting a(not crowded) place with public Wi-Fi, and see if the issue persists.
If it starts to work fine, get a new router, preferably with 802.11n support. If you buy a N compatible router, check all of your Wi-Fi capable devices for N support, and if one of them doesn't, make them N compatible(if it's a computer, get a new N compatible Wi-Fi card or USB reciever, if it's something else, well, you can't do anything else other than buying a newer version of it with N support, or not using that device's Wi-Fi feature at all) because your router will operate at an older mode even if one of your devices doesn't support N.

[Q] GPS interfering and stopping cell signal!

Hi I have had my X10 Mini Pro for over 2 years and run various roms and kernals on it but recently have a problem I have never seen before, when I am using my GPS either in Google Maps or Endomondo it works fine but it kills my cell signal both data and cell coverage drops to zero and just says No Signal. To resolve I have to exit out of my app and reboot but it keeps happening every time I start using the GPS... has anyone come across this before or has any idea's on how to fix? Am running nAa's Gingerbread Kernal v13 and latest build of miniCM7-2.2.1-minimi, I did clear the Dalvik cache not that I thougth that would help but only thing I could think of beyond the next step of wipe and fresh reload...
Any help appreciated.

Weird bootloop out of nowhere when network is active

Hey
I own an S2 i9100, using CM 10.1 (latest stable). I haven't made any ROM/kernel change for as long as the stable came out.
Yesterday out of nowhere, my phone started boot looping, and I have no idea why. The phone boots completely and after a few seconds just crash.
I've looked at the logcat during a crash and couldn't make something out of it.
I've read the last_kmesg and couldn't find any leads.
My biggest clue is that I can totally prevent this from happening when I shut down the network (both wifi and GSM). A few seconds after one of those start, the phone reboots.
Bluetooth tethering for internet access doesn't crash the device. It sounds weird, so: Are there any operations that don't run on BT and do run on other types of networks? I might be able to narrow it down this way.
Also, I'd love to hear other suggestions, but I don't want to hurry up and wipe the device just yet.
Thanks!
Asaf.
Asaf try to flash another ROM and test network again to try or it was ROM related hardware related or something with baseband
