Galaxy S2 Slows down when WiFi turned on - Galaxy S II Q&A, Help & Troubleshooting

Hey,
It's my first time posting a problem cause I used to find my answers in others topics, thanks to your efforts. But sadly I didn't find a solution for this problem.
I have a galaxy s2 GT-I9100, It was working greatly, but for the last 3 weeks, once I turne the wifi on, the phone slows down immediatly. And when I turn the wifi off again, it goes back to its normal stat.
I tried at first a factory reset .. It didn't work.
I flashed the ROM with an official JB .. It seems working for a few days, but now the problem is back again.
To give you more details : when I turn the wifi on, the menu start "lugging", and when I use the virtual keyboard, when I click on a character, it stay clicked for a long time, and if I want for example to delete a letter, the backspace button stay in hold, until it delets many lines of the text.
And many other things !
I wish that you can help me fix that.
Thanks for your efforts.

It's look like HW problem..

I'm sorry, but what does HW mean .. And how can I fix that ?

Probably apps waking up and syncing when they're told by Android that there's a network connection.

I don't think so .. cause all the apps I have are regular apps : Viber, Skype, etc.

It's NOT a hw (hardware) problem.
Any app that accesses the internet WILL attempt to sync when a connection is available.....even those that don't normally use it could.....just to check for updates....
Take the sync advice...it's more possible....
Temporarily disable sync before enabling wi fi and see if you notice any lag then....I bet it will be minimal.
My wife says I'm a phone geek....She's probably right

I disabled the sync, but I don't think it helped a lot .. Maybe a tiny bit, and thanks for that, but the phone still slow .. For example I still have that keyboard issu .. do you suggest any other tips to do ?

My kids have cheapo generic android tablets......if they start lagging or doing weird s**t, I boot the tabs into recovery and wipe cache and dalvic......that usually helps.......

It seems to be working for sometime .. But I think It was an illusion .. The phone is still terribly slow when all the time my wifi is on ..
I confirm that I have Viber and Skype and Telegram installed, but they were there since I bought the phone ..

i have them too but the phone is so fast i advise you to go to clean master and ther memory boost and select all the apps to free memory and create a widget of memory boost on the screen from apps widgets and search for clean master memory boost and since you see that your phone becomes slow click on the widget :good:

[Q] [APP] DroidSheep stops monitoring after a while

Hello Guys!
I'm playing around with Droidsheep and after I press "Start" it sais running.
Now i'm surfing around on my Laptop and is grabs one or two sites I'm surfing to, but then it stops monitoring.
If I stop and start the service, then it's the same again.
Tested Version 13 and 15 out of this forum here.
Anybody an idea?
Thank you
Sorath
PS: Using Samsung Galaxy S with ICS and router is Fritz!Box 7270.
same here.
Try to restart the app,kill it in the task manager and free some RAM i got that problem to and i solve it using this trick or you can restart your phone for better result but killing it in task manager is enough
Sorry for the bump guys,
I'm still having the problem,when I hit the start button the status reads running and spoofing but after (less than) a second ,it says idle and don't pick up any sessions,I tried rebooting ,reinstalling, clearing ram. I'm using a near AOSP stock rooted ROM (Device: Moto G 2014)(OS:stock 5.0.2)

[Q] Network data and WIFI disconnect when the screen goes into sleep ?!

so i got S3 a week ago . i had many friends having it i even helped them to update it many times .it came preloaded with 4.0.4 ... but i directly updated it to 4.1.2 using odin ...and now runing on XXEMB1
done factory reset ...and rooted it ...after a while of use i noticed that the network data connection and the wifi get disconnected every time phone went to sleep .
...so naturally ...i tried another factory reset ..but no joy so i did another flash using odin without rooting this time
and yet wifi problem remained ..but could stay connected to data after couple of days went back to losing both if it goes to sleep
i have tried the *#0011# fix but nothing changed
in wifi settings ,,,it is set to always stay on during stay ....
i would appreciate if some one can point me to the right direction ...since replacing the handset is no option :/
is it a faulty handset ...cuz i used the same firmware over my fiancee's phone and it is fine ...same for some of my friends ...so i think it is about this phone in particular ....any help plz !
i guess this is mark it as either : stupid question , something new ,, or just with no fix :/
Dunno if this helps, but try juice defender, it has a lot of options to configure, and as i remember, it has one to keep conectivity on while sleep

Hi Infernal88,
by replying the post in such a manner doesn't make you not stupid.
Hi All,
I am also encountering same issues as TS. Is this a rom issue? or hardware issue?
Thanks

BUT, on my phone, when i turn wifi 'ON' , the wifi works for 2-3 minutes then it automatically disconnects and then instantly reconnects itself! I dont really have problem with this thng but the other day i was upgrading my swype to swype beta and had to download this application but the app is too large sized that in the middle of the downloading my wifi went off thereby stopping the download(n sadly its non resumable). I am a huge fan of swype and have been using it for quite a while now. I want it upgraded at any cost!
I know this wifi turn on/off problem is faced by many but this is quite a headache nw! I have come to know about 'POWER SAVING MODE' n stuff, but sadly i can't even get to that menu coz i dont know how to!

[Q] Samsung Galaxy S III GT-I9300 Wifi Doesnt Turn On!!Please Help!!!!

I have a samsung Galaxy S3 GT-19300.I got it from Italy.I Used It for sometime and then the update 4.1.2 came out.So I Installed It.Then Minor Wifi Problems Came.I somehow Fixed It,using Methods I Found From The Internet.Then I Didnt Use Wifi For Sometime As My ROuter Was Broken,And When I Got A New One ,I Tryed connecting To WIFI ,But It wouldnt turn on.
In The Notification Panel when I Press the wifi button ,it turns light green and then becomes normal again.In settings when I Go to Wifi and turn it on,it keeps on saying turning on for sometime and becomes Off again.
I almost Tried Every Solution On The Web.I Tried Dialling *0011* and turning power save off.I Flashed New Firmware around 4 times.(now im currently running 4.3,got it from Cnet)And In All Of Them ,Wifi Doesnt Turn On.Then I Went To Desperate Measures I Rooted My Phone,and tried many Fixes But It Still Didnt Work.
Right now im thinking,something must be wrong with the phone`s wifi adapter.(Physically)AND HOW I WISH THAT IS WRONG.
So i Really REALLY APRECIATE It If U can Help Me.Now That my warranty is void as well,U People are My Only hope.Im Running Very Low On Money so im hoping For A Free Fix.I still even have the Idea Of reverting it Back To 4.1.1.But that Would Make My Phone Lose A Lot Of Features,i Dont Like That.But Anyway If Thats My Only Choice Ill Take It.
Also I Live In Sri Lanka,I Tried Another Reigon update and then My Mobile carrier Didnt work,also wifi didnt work as well.
This Is My First Post Any Help would be appreciated.
Thank You.
P.S - I Would Rather Prefer A Fix In 4.3 or 4.2.2 Other Than The Link To 4.1.1.

e your phone has a hardware fault .

Sofkeys autopress !

1. Softkeys ( Menu and Home ) starting to auto-press today suddenly for no reason. Before you ask , I don't droped my phone or any type of shock !
2. After some time sofkeys ( Menu and Home ) stop working at all ! They don't even light out if I'm trying to press them... Although the 'Back' key is working perfectly fine.. :/
These problem solve magically after one restart but after few minutes they still persist ! Sometimes working fine , sometimes autopressing or not working at all and after a while working again.. :/
Anyone else had this problem too or know how to fix it ? ( if it's even possible to fix )
P.S. I don't think that's an Software problem , I think that's an Hardware problem tho...
EDIT : My 'Menu' and 'Home' buttons are officially dead now... R.I.P. !
I have the same problem... After updatee from 7.1.3 to 7.5.1 and to 8.0.1. I tried with custom ROM, with stop Tapatalk... But without success. I tried also with another launcher and they start to work for only 10 minutes.. tried also with wipe cache! This is very big problem

That's not a Software problem , that's a Hardware problem...
In my case all started yesterday... Menu and Home keys started to autopress/not working and until night they stopped working at all , completely dead ! That happened suddenly , I never had that problem or have dropped my phone , never !
Also I read that many Xiaomi have this problem including Redmi Note 3 and even Mi5
R.I.P. Soft keys !
Now they work again after whole day that they don't worked at all now suddenly starting to autopress again and works pressing them :/ They worked again ( including autopressing ) just for few minutes and then not working again..
I'm starting not to understand this device at all !

Acutally it's software problem... I'm sure because when i deinstall Taptalck updates, they start work correctly for around 15-40 minutes. After that they just died. After install new launcher (from Gplay) they start to work again. So im pretty sure that, this is software problem... But from MIUI dont care about our problems

I don't know... I'm using exactly the same apps like always , never had that problem ever with any ROM... Last night I flashed Stable 8.0.2.0 , they worked for few minutes and then dead again !
I still think that's an Hardware problem , but I really hope I'm wrong and you're right to be a Software problem..

Exactly same problem for me. Sometimes it start to work ( very rare ) or auto press but I disabled Menu and Home buttons because it's annoying to get out of app because autopress.. Have you tried to flash latest fastboot ROM ? If it's from software that should solve it..
Or this problem its in the kernel of Miui... I dont know, how to check. But i buy new display, and nie im waiting for it. When i change My display will text you

I thought buying new LCD too but it takes too long to deliver and I read some bad reviews about them : not original , dead pixels , crash during transport , etc. I'm thinking buying a new device maybe...
Anyway I'm really curious about your new LCD , so please tell me when it arrive and how it works :fingers-crossed:
Btw you bought just the LCD or LCD+frame ?

Only Display, i will text you when i finish with rhe display
I had the same problem. If you are using custom rom, you can activate on screen home button and disable softkeys, this may help for a while.
But it still will make some phantom touch on your screen. Finally I sent to repair and they changed another screen for me
Hello dear friend! I changed my display... And now everything is good. Buttons work properly. And I have good news for you. I just finished with one test: I put the old screen again on the phone and now the buttons work again... I just heating up the display when I was removed the old screen. U can try to heat up your phone on the button of the screen with hairdryer gently. Or just disassembly your phone and assembly again if u have any questions I'm here
@vetefan I already disabled Home and Menu buttons because it was really annoying to always get out of apps suddenly without pressing anything !
@ZinovievBG Hey mate ! Few weeks ago I opened my device to clear dust in front camera and also I cleared everything in it including a bit display stuff ( you can't really clean too much display because it's one piece ). I'll try heating soft buttons with hairdryer and see if it works. One question : this heating solved the problem definitely or just for a temporary period ?
