MHL cuts off the WIFI and Phone signal

hi.
i just got a MHL cable for my SGS2
when i plugged it to my tv, it cuts of the wifi and the phone signal... so i can't receive calls or surf the internet ...
i tried two different phones with different roms and different kernels and got the same result...
anyone had this problem and knows how to use MHL and have WIFI and phone signal?
thanks

What cable? Samsung's or generic?

Have you tried this on stock unrooted or rooted firmware?

i tried custom roms...
one of them is 2.3.5 and the other one is 2.3.4
the two devices are rooted

I have the OEM Samsung adapter and it used to make my phone do the same thing. I sold the phone ans ended up buying another one and the second phone works perfect with it.
I am running the leomar75 rom with the ragemod 1.1b kernel

so you say this is a problem with the device itself?

I also have a generic adapter but mine works for a few seconds and then blank.....not supported. sometimes it gives green screen on my tv. I've tried on stock and custom roms. If it's the phone than it should be addressed t Samsung.
update:
I have to put my phone in offline mode to be able to use it.....

i tried the same cable on other tv...
on the other tv the phone signal stayed on (and i even received a call without any problem) but i still had no WIFI...
maybe its important, but i tried the other tv away from home..
at my home the phone signal is weak all the time

i have a stock phone w/ generic POWERED mhl cable and the wifi cuts off when plugged in. wth?

still no fix for this issue?? i just got a MHL cable yesterday and is really annoying

I called samsung and they said that it is designed to cut off wifi. it may look like u r still connected, but u will be unable to surf the net. they said the reason this was done was to prevent fickering of the video if you were browsing the net or something.

so ,there's no hope than MHL work with wifi?

dont ask me. call samsung. just telling u what they told me. the way it is designed wifi is shut off when mhl cables are used.
would be interesting to see if anyone got wifi to work w/ mhl plugged in.

I have had WIFI working with MHL connected for months. I've could surf the web AND stream flash videos in a room with GPRS coverage ONLY (which rules out the "you were surfing through packet data" variable) while connected to my Samsung HD plasma with no problems.
So I certainly have no idea what your Sammy rep was talking about.
BTW, I'm using the official, korean spec MHL cables I got from ExportPrive. But I'm positive it should work the same with the international MHL cables.

Bought a non Samsung MHL cable today and it worked perfectly fine, it even worked when providing power via a microUSB cable connected from a spare USB socket in my nearby router.
Another user on a forum I frequent has similar issues with WiFi dropping and had this solution:

So maybe try a different charger?

Another OcUK user
My MHL problem is fixed now, i tested it for 15 minutes and wifi and gsm signal were fine
I was just about to post it in this thread and then saw your post haha
IF anyone decides to mess about with chargers/adapters with higher currents then do it at your own risk and read up if its ok to do so with your phone etc..!

I try with my nokia N900 charger and still nothing, I'm using the official MHL cable

Rom/kernel issue?
I'm using a Nokia AC10X (1200ma charger) + original MHL cable + Siyah 2.1rc2 (at that time, now running 2.1.1) + VR2.4.2 (don't ask) = no connection issues what so ever while in HDMI out.
Either that or it's a hardware problem with the cable or your phone.

Rebooting when MHL is Connected [Docomo SC-04D]

I first bought the Samsung brand MHL adapter, and the moment i plugged it into the phone, it simply reboot without displaying anything on the TV. I figured it might be the adapter, so I returned it and bought a 3rd party Menotek adapter only to find the same problem.
The power cable is connected to the adapter, and the adapter to the phone and HDMI cable. I even tried a different power cable, and wall charger and same problem occurs.
Is this a problem with anyone else, one that has a fix? If not I might have to exchange my phone, since this is a feature I really wanted.
Could it be perhaps that the Docomo (Japanese) version uses different electric current that it has to convert, but the adapter can't convert?

i have the exact same problem.
at first i thought it was the cable, so i exchanged for another one... it rebooted.
then i thought maybe it's the tv, so i tried a friend's tv... it rebooted as well.
so i figured it must be the phone. but then since everything else was working perfectly on my phone, i couldn't be bothered to go exchange it... i thought i'd hardly use the mhl if at all. guess you should go exchange yours while you still can though.

I'll contact newegg about it, see if I can get a hassle free exchange.
My biggest guess is that is has something to do with the 110v/220v electrical current that it either doesn't receive enough, or too much, causing it to restart.
I am not sure what a good solution is. At least I am not the only one.

hmm i doubt it's got anything to do with electric currents.
it's my understanding that standard usb power is 5v.
anyways japan uses 110v same as US, and i'm in asia 220v and we're having the same problem.

I had same problem as this but the jelly bean update fixed it....

110/220 is AC, which is converted to DC before it even gets to the usb cord, let alone to the phone. Most chargers will support 110 & 220, so there shouldn't be any issue there.
Are you rooted? Have you tried any other ROMs?

i have the same problem and the jelly bean update doesn't fix this problem, any solutions?

I9250 suffers from defect as well
I have problem. Using i9250 original international version. MHL worked once upon a time, jelly bean didn't fix it, started in 4.0.4, last worked in 4.0.2, dont care about downgrading just to examine, but going back to stock 4.0.1 or 4.0.2 might fix it

Ahh forgot about this thread. Using bigxies deodexed rom got it working for me you can find it in the dev forum here.

serious USB-port issues

Hello!
First things first: i already googled and search-functioned about 8 hours for solutions, tried them all and still got no luck so basically you girls and guys are my last hope. i hope my english isnt as rusty as i think it is. if i make any mistakes of any kind, please bear with them.
Used Hardware: Galaxy Nexus, the original Samsung OTG cable and the original Samsung charger
Software: Rooted, Bootloader-unlocked, stock-Android 4.0.4, 4.1.1 and 4.1.2
What is my problem?
as soon as i plug in the original charger it charges (duh!)
however, the moment i unplug it, the phone keeps thinking it is being charged. forever!
plugging in a original samsung USB cable without connecting it to something doesnt help, it still thinks of being charged.
but plugging in the original OTG cable stops the phone from thinking of being charged! (i dislike the thought of running around with a OTG dangling around the phone so that isnt a solution to me )
what happened before that incident?
bought on 15th December 2011
last software update 4.1.1 to 4.1.2 on 16.10.2012
worked perfectly until Yesterday
Recently i played around with the OTG cable and tried the following hardware to see wich works with my setup:
external HDD - NTFS formattet
PS3 Sixaxis controller
Corsair Flash Voyager USB3.0 Stick
AKAI MPK mini USB MIDI controller
Newest apps installed:
Sixaxis Compatibility Checker (18.10.2012 installed, used for half an hour and deinstalled)
Wolfram Alpha (17.10.2012 installed)
MyBoy (an GBA emulator - 12.9.2012 installed)
-latest ROM for that emulator downloaded on 13.9.2012
what did i try to fix the problem (in exact order)?
rebooting
changing the battery from 2000mAh (its an original, bought about half a year ago) to stock 1750mAh
removing the battery for 10 minutes
draining the battery to absolute zero and fully recharge it
carefully cleaning the microUSB port (with battery remover of course)
super carefully bending up the thounge-like part inside the microUSB port so that it doesnt get in contact with any surrounding metal parts (battery removed of course. when i say super carefully, i mean super duper carefully! i know how fragile those parts are!)
trying to hard reset the phone (that was a failure i just got from fastboot mode to a droid with a red triangle and an exclamation mark on its open stomach)
factory resetting the 4.1.2 via factory reset option (backup with Titanium Backup was made correctly but i forgot to copy it from droid to PC :silly: )
wiping the cache via fastboot
quick reflashing the 4.1.2 via fastboot
quick downgrading back from 4.1.2 to 4.1.1
quick downgrading back from 4.1.1 to 4.0.4
quick upgrading to 4.1.1 (it still is in that state)
complete reflashing the 4.1.1
- with reflashing bootloader
- with reflashing radio
- with reflashing recovery partition
now i am out of ideas
i think the USB port is seriously damaged. but since i am not so good with soldering and electronics i fear that i am not able to exchange that.
any more suggestions or ideas what might have been the cause?
next few days i will take it to the service center wich i really dislike to do because here where i live that means they keep it for about 6-9 weeks to fix it and i will not get a replacement in the meantime. anyhow my hopes are low that they might fix it i rather believe they replace it for a new one wich i also would dislike. Good thing i made a insurance for that device so in worst case i dont have to pay a single buck...
greetings everyone

Weird. Did you try flashing a stock Google 4.1.2 image? (Check out mskip's thread in Galaxy Nexus Android Development and download the toolkit - make sure it's compatible with 4.1.2 first)

Yes your USB port is most likely broken. Many others have had this problem including me.
Mine was so bad that my PC wouldn't recognize it and neither of my pogo pin docks would work.
I replaced the USB flex cable this week and it works great now. It was a relatively easy repair if you take your time and have the right tools.
The part only cost me $7. http://www.ebay.com/itm/190704059979

thanks mohitrocks but i also tried that, not only once.
El Daddy are there some how-to's? If it is easy i will try to do this before handing it in to the service center.

The USB ports should be the same as micro sd is a universal standard I believe.

I had that same issue after my phone got wet. After about 2 weeks the issues with my USB port went away altogether.
You take your phone places where water might condense on/in it?

thanks miketoasty and thanks El Daddy! i really like this forum a lot very helpful people here.
i ordered the part. Estimatet shipping date somewhat between 30. october and 5. november.
will post updates
at least that error of mine doesnt drain extra battery
reuthermonkey:
i cant think of any place i visit frequently with high levels of moisture or with wet places. I am really careful about that because i love my Nexus witch even goes as far as never ever taking it into the bathroom (not even to a save and dry spot) while showering or bathing. Rain is a bit rare here and even if it is raining i wont leave the house without putting the phone inside a phone-pocket and into the inner side of my jacket.
greetings

I had the same issue as you. I ordered a new charging port cable for $7 on ebay, installed it in 15 minutes, and all is well in the world.

If anyone else is having issues, I have a spare USB flex cable that I can send you for just the price of shipping...most likely $3 or so.

[Q] boost samsung 4g touch question!

I'm a noob, and i have a boost samsung 4g touch, but its marked as an s2. With that being said i bought a Juiced systems adapter to plug into my phone to read memory cards from a digital camera i have. well just my luck it don't work, The guy who sells these adapters was very helpful in trying to figure out why my phone does not see the adapter, he rooted my phone, didn't help. returned it back to stock for me (un rooted) and he has gave up. Anyone have any ideas? Model SPH-D710, android version 4.0.4, build number IMM76I.FI27

Odd that the person put you on a Sprint build for Boost... but we can address that later.
According to this you have to have to be rooted - which being on Boost you should be using Boost's FI22 rooted one click , have Stickmount installed from the play store and not be trying to use any of the other functions. This includes not plugging in the power as it sounds as if it switches automatically to MHL mode.
Hope that gets you in the right direction.

Android Auto Issues

Does anyone know of custom Roms for the OP3 that Android Auto works well on? I have tried OOS 3.1.3, unofficial CM13, and Bliss.

anybody?

Apparently not

I am using stock ROM and Android Auto is working fine. Except that sometimes I have to go to the car dashboard and activate the device for Android Auto. This does not happen all the time.

In my 2016 Golf 7 everything working like charm, no issues, less than with my S6 before...

That great! I also have a very golf and could not decide if I should buy or not the op3
LE: what cable are you using between the OP3 and the car ?

Well you two are the only ones I've heard of that aren't having issues with crashing/ disconnects. Consists yourselves lucky.

Which deck do you have @dindoliya ?
Anyone who has seen my various post with problems already know I am using the Pioneer AVH-4100NEX and factory cable with no luck, but works fine with 1+1 and Note 5 and even S5.

Hi, I will check which deck is there is my Chevy Volt 2016 and get back to you. From what I can recall, it is probably a Panasonic.

Just wanted to let everyone know who may come here searching for similar problems. I did finally get mine working with a different aftermarket cable. Have had no disconnects with AA or BT. Ironically it was a cable that will not even allow DASH charging but will work with Android Auto.

Ok, after 2 Weeks use, I have to say, that the only combination I get this to work without disconnects is with the original cable.
I tryed different cable from cableconnection over anker to belkin, none of them worked properly with op3... Some even get no connection at all, others disconnect connection after a while...
Only with the original cable I get this working properly... really strange...
I will make one test again this evening with original cable. Never used this since the update to 3.2.1, so perhaps this is the reason...
I'll let you know...

Does it mean that mirrorlink is supported by 1+3 in general?

Never had any luck with the factory cable as well as a third party cable. I did however try a third cable which has been working almost flawlessly.
For those interested it's this one:
https://www.amazon.com/dp/B013187HZS/ref=cm_sw_r_other_apa_MbxGxbTJ8QTRK

Ok, verifyed..... Form me in My 2016 golf 7 only the original dash charge cable works without disconnects with 3.2.1.
I will order a second one now....
Don't know what is so different on this cable but something hast to be...

Very good news !!!! Thanks for taking the time to tell us.

Can I ask how you got this working? I'm getting frequent disconnects with the op2 cable and third party type c cables. Not tried the dash cable as yet

since I'm using CM13 never got any disconnecty on android auto.... perhaps OOS is the reason for that issue....

I'm not sure how big a part OOS plays. The cable i linked a few posts up has worked for me.

I get occasional disconnects too. Not that bad, but annoying at times. All it takes is unplug/plug the phone back to get it going (Pioneer AVH-4200NEX). Noticed that happens most often when I'm driving in an underground garage and the phone is seeking signal (2G especially). Cable I'm using is 3rd party Amazon sourced one (flat cable). I'll see if I can get a properly RF-shielded USB cable to see if it makes connection more reliable.
