Wifi Range problem - Galaxy S III Q&A, Help & Troubleshooting

My S3 I9300 really wierd.
The wifi works if im right beside it, but if im 2 meters away, it doesnt..
This problem is only on my ohone. Not computer or other phones.

Not to be confused with a cwm full wipe. I searched and searched and this is the only way

Question about flashing back to stock.

Hi, I recently flashed back to stock Rom and all was good. My device status was normal, flash counter reset. But today after a week it says modified. Can any one help me out on this. I don't wanna keep flashing stock every time it says modified.
Thanks.

Just an update. It's gone back to normal by its self. I haven't installed or installed anything. I find thing kind of weird. How is it possible to do this?

use triangle away from playstore
There will be no triangle away without root...
THe only thing you can do is:
Root, triangle away, reflash stock if youd like to have an out of the box phone
I have done all this. But it changed by its self to modified and has now gone back to normal :-$ that's what I find weird lol

Why is my WiFi so slow at work?

It Works ok if im less than 5 meters away from server. But anything over that and its unusable. I work about 10 meters from the server. And I get at least 2 - 3 bars of signal out of 4. And I can't even post a comment on here. The speed is very fast for about 30 seconds and then ridiculously slow. It also struggles to connect. Tries about 3 or 4 times before it connects. I'm running cm10 on s3 but have this problem on stock, omega and checkrom. I had simular problems with the s2 aswell but not s1. I don't want to use wifi kill as its my work and it might not solve the problem. Is this the s3 working on networks with multiple apns? Is there a code I can call to turn off power saving ?? Can't force to 5ghz either.
Some advice would be massively helpful. I am getting very frustrated.
Thanks in advanced

[SOLVED]Headphone socket problem

Hey guys.
My phone can't play songs via headphones - there's no sound coming from the right side. I've already cleaned the socket and the problem persists so it isn't in the headphones.
Does anyone else running cm-10.1-20130504-NIGHTLY have this problem?

Have you tried restoring back to the previous rom you had? If the problem follows, its hardware or data. If not its rom or data.

Wiped data and flashed 20130501-NIGHTLY, the problem is still there.

Click to expand...
Click to collapse
If it wasn't there on that ROM version before, then it's hardware. Possible a loose connection in the socket or fluff,. have anotehr look inside if you can. Otherwise, reflash stock and send for repair.
The problem's in the hardware, tried moving the plug and sound was coming temporarily from both sides. Taking the phone to repair so thanks for help and whatnot.

4.3 stock battery problem

Im pretty new here on xda as you see
I installed the stock samsung 4.3 update thru my phone ... my battery got worse.. is there any fix for this maybe?
Thanks
See multiple identical posts .
Ive searched and searched ... cant find it
Sent from my GT-I9300 using xda app-developers app
There isn't a quick fix and instant solution, you'll need to search for similar problems and read through their actions.
Search for better battery stats, bloatware and social media apps.
You might be better to factory reset and format your internal sd card after updating to 4.3, most people have a better experience afterward.
