[q]Wifi problem - Galaxy S II Q&A, Help & Troubleshooting

My phone keeps freeze when I have turned the wifi on.
When I turned on the wifi, and wait for a while,
it will disconnect and keep re-connect.
This made my phone almost freeze,
what wrong about my phone??

Bit vague there. A bit of info about your setup might help (kernel, rom, etc). We're not mindreaders

Oh, sorry.
I am using SpeedMod K2-19,
Simple & Clean v2.4.3 rom.
And this problem occurred in 2days ago,
I have reinstalled the rom with 4 wipe.
But the problem is still there.
Hope you can answer me.

I have flashed another rom ROMOW-V1.
It is a new rom which launch recently.
The wifi issue seems to be disappear,
but it still needs to wait for a few days to confirm.
Thank you

Unfortunately, the issue has not gone.
It still annoys me which cause my phone sleep of death twice.
I want to find out what's happen to my phone, thank you!!

[Q] Problem, Stuck in Black screen doesn't wake up

Hello!
Well... I have this phone since yesterday... I plugged to the computer with Kies, and well, a update was available... now the phone have Froyo and the aesthetics changed completely, it looks awesome.
But, the phone have this ANNOYING problem that, after using it... like 5~10 minutes of no activity, when I try to use the phone again it doesnt work... doesn't respond to any button, I have to take off the battery in order to restart it and that over and over again...
I've realized also that this happens when I'm using wifi, if I left the phone with wifi on this happens, without wifi seems to work fine.
Somebody have any clue what could be? there's little information about this issue in the internet...
I think I'm going to return it but I want to try everything I can do (without voiding the warranty) since the phone was perfect for what I wanted.
Thanks in advance!
Hey. I got the same problem here. It only happened a few times when I just had froyo that came stock on my galaxy 5 but I recently installed cyanogenmod 7 and now its happening everytime I put my phone down.
So I'm guessing it may be directly related to what rom is installed? I've heard about it happening a bit to people who have 2.1 installed to.
I dont know too much but it seems the only fix is to take out battery and turn on.
Sorry I can't help more. I hope somebody knows a bit more than me on this.
Think this is called something like the 'wifi sleep of death', something to do with the rom. i'd try change the rom and see if it still occurs
Thanks for the hints tho!, but I returned the phone... it seems that is a bug related to the update of the phone, since I know that with the out of the box 2.1 version it doesn't have that issue...
You know, the mobile carriers also do weird stuff to the roms... -__-

[Q] Problem: screen turns off (and sometimes turn back on with high brightness)

I've searched the forum but I didn't see a similar issue.
My phone is new, I bought it a few days ago and it came with 2.2.1 froyo.
As a xda user, I started to search for roms and decided to try the CodeROM v2x-2b.
I flashed KPN and then the CodeROM. The flashing process ran without problems.
The system is running well except for 2 problems:
One of the problems is that when I'm using the phone, sometimes it's screen turns off. Sometimes it turns on after a moment, with a very high bright level. Other times it just remains off.
In both cases I must press the power button twice (as I was locking and unlocking the phone) and it comes back in lock screen (wich means the system doesn't freeze, it's just a screen issue).
Sometimes it happens quite often, sometimes it takes a while to happen.
I flashed Gls-mt-ROM today but the problem continues. For me, it indicates it's not a Rom problem.
The other problem I'm still gonna research a little more before posting here.
Does someone have a clue about what can this problem be?
Edit:
I reflashed CodeRom with the brazilian modem file from this thread.
Until now, seems to solved the screen problem. Seem to solved other 2 problems too (GPS and wifi).
I can't figure how screen and modem are connected.
Does this information make any sense?

Hey!
Dose you done the WIPE? Factory settings?
CHEERS!

Yes.
I think I did it before and after flashing the CodeROM (the tutorial was saying to do so) and before flashing the Gls-mt-Rom.
I don't think doing it again will solve the problem. Should I think that?

[Q] Can someone help me? My phone keeps freezing and buzzing

Hello everyone,
To be honest, it's been some time since I've been here, back when I knew how everything on this forum worked...
I kinda forgot, so I'm just posting this HELPME!? thread
This is my problem:
About 1.5 years ago I downloaded a ROM, and put it on my phone, and it was working just fine. However, 3 weeks ago it became really annoying, i'll explain what my problem was:
My phone would randomly freeze when i was doing things, these things could vary from "sending a text message" to "opening my 4th opera tab".
After that it wouldn't respond unless I reset it. However, when starting up again after resetting it would do a few possible things.
1. It's freeze at the first startup screen.
2. It's keep switching between unlock and "pin-screen", and when it was working again, it'd freeze.
3. It'd start up, and after about 5 seconds buzz like 5 times, then freeze.
When i left it on frozen the battery and phone would turn very hot as well =(
So, I tried a hard reset, but that didn't work.
After that i went to the following thread:
http://forum.xda-developers.com/showthread.php?t=591784
I followed the instructions, installed the right Radio (2.12.50), and installed the ROM ( Energy.Leo.21916.Sense2.5.NLD.Cookie.2.0.Jul.07.7z ).
I remembered how to intall these things, so I think i've done that right.
So, after that it seemed to be working fine, and I was really proud and happy.
Now my phone has frozen again, and starting up was an issue again...
Does anyone know what my problem is? And what would be even better, what i can do to solve it?
Please let me know <3
Adios <3
Little Update:
So, I've been carrying my HTC HD2 around with me again, and then it started again...
It froze when I tried to send a text, and after that would freeze or vibrate (a few times) during the start-up...
It's really anoying =( If I'd have to estimate my phone's uptime a day...
It used to be 24h a day, now it's more like... 4 hours a day, with 2/3 hours of trying to get it working :Z
That could be hardware related. Possibly processor overheating. I would download the latest stock rom and fash it to see if it sorts the problem. If not it will need to be sent of to HTC to be replaced.

Phone randomly freezes

Hello everyone!
A few weeks ago my phone started freezing randomly when navigating through menus, when turning on the screen or just during stand by. It reboots almost every night and I find it in the morning in the "enter pin" screen. I have been using the Omega Rom series for a long time, and I was using v38 when this began to happen, but by that time I had already been with the same ROM for a long time with absolutely no problem. Yesterday I updated to v39 and the phone is totally unstable, it freezes every 5 minutes and I have to remove the battery.
How can I know if this comes from a hardware or a software problem? Is there any way to log what the phone does so I can check what goes on by the time it freezes?
Thank you very much.

you could try to do a logcat report.
did you try different kernels?
Yes I did, I tried the stock kernel and Siyah too, but I get the same problem. Any other recommendation?
I will get started with the logcat thing, I hope I can find something. Thank you!
My droid4 kep doing the same exact thing when I attempted to listen to my music player, and I ended up finding trojan and I didn't find it with any of the AntiVirus' that you find on Android I ended up finding it with pandas usb vaccine when I plug the phone in to the laptops usb port.. And it doesn't do it at all anymore
I tried 3 AntiVirus ' from Google, AVG + lookout+ .AND avast..!!! Nothing picked it up. :banghead:

if it is not the kernel, I would try to setup the phone from scratch with first, a stock Samsung rom, see how it goes, and if anything is ok, flash a custom rom and test again.
Usually, for me, I do not stop with just a factory reset but use a "mega" wipe to delete (not format) anything related on the phone even if some think this is not necessary.

Hi.
I've been having similar issues for over a week now. And have removed some programs and setting trying to find the cause. Eventually what has prevented freezing is when I turn the screen power saving in power saving settings on. I'm thinking the GPU might be somehow damaged or something.
I have only installed the official updates to the phone. Currently I'm at 4.1.2 NEE.
Ive been using custom roms for ages but got fed up with apps and certain not working so I wiped everything and installed stock ics via odin, I then upgraded all the way up to 4.1.2 via the Samsung upgrade utility but....... now my phone freezes sometimes ive never had this before. ...? Im on ella btu

I have been doing further investigation and I've seen that it is not that the phone freezes, it is just that you cannot have any interaction at all with it. The screen is blocked, the buttons do not respond and the phone does not make any sound, but I know it is alive! I know it because whenever an app is doing something, after restarting the phone by pulling out the battery I see that that process has been completed or if I dial my own number from another phone I get tone, although the phone appears to be completely dead...
Does this situation have a name and a specific solution...?

random freezes (with CM roms)

Hi, I had CM10.1 running for a while. Since a few weeks I got random freezes when I wanted to turn on the screen it stayed off (LED was flickering, so the phone was still on). After a forced reboot (vol up+power button) it worked, but as it kept happening I wanted to try a full wipe. By the way: it happened every single night too, my phone was flickering its LED, but didnt react, and also alarm wasnt working (FML).
When messing around with this (I'm not really an expert at flashing/CM) and trying to restore my phone with TitaniumBU it kept freezing when working (to) fast. So I tried a lot with formatting SD, doing other wipes etc. Nothing really seem to help, as the random freezes kept happening.
Now I've installed the stable CM9, but already had freezes (even with the startup wizard in the beginning). I'm getting the feeling that its some hardware related issue. Can anybody tell me more about these problems, and mayb what else I can try.
Last try is to turn it al back to Touch Wiz, unroot, but I have to figure out how to. Hope this will solve it.

Sorry, plz move my thread where it belongs (im noob).
After some searching I found that it might not be a CM related problem, but something with 'sudden death' happening to more people with other ROMs or even without custom roms.

New development: my phone is now stuck at Samsung GSIII logo. Doesn't go further from there. I'm planning to go to Samsung with it. It is not unrooted, so my Q is;
can they see that it is rooted when the phone doesn't get past the boot logo?
