Hey guys, anyone have issues with MHL and the z2?
I have a 5 pin MHL adapter and cables in working order. I have tested with other phones in the house and they work fine.
When I connect the Z2 I get a blank (black) screen for a few seconds and then the HDMI no input signal comes up. If I play with the phone's touch screen I can wake it up to a black screen again for a few seconds. Never is the actual picture transmitted.
This is using the most recent paranoid ROM 4.6 Beta 3. I don't know if it ever worked on this phone because I don't think I ever tested.
Ideas?

alot of non stock roms usualy have these featues non working, this could be your cause, if not this then the cause could be your MHL addaptor, Z3 supports MHL 3.0 and this may interfere with other devices compatability
Apparently this issue was a connection issue. I spent some time playing with everything and got it to work. I am not sure why I had such a hard time with the Z2 when the other phones just worked right away and weren't fussy at all.. Such is life though I guess.

I have had problems with cheepie cables from monoprice. The mini hdmi connector is intermittent. Better cables work fine. You may want to try another cable.

I had this problem the first couple times I tried hdmi. Then one day it started working and its been fine ever since. I'm not really sure what the problem was or how it was solved.
I don't get a menu to select mirroring anymore. I used to have it with this cable and this tv. It's not an option now. I just get a Motorola logo on the tv. Mirroring used to work a few weeks ago, so something has changed with the phone. I'm not running a custom ROM, haven't disabled anything and no special software. Rebooting doesn't help. Anyone found a fix?
the first couple of times I tried I would just get the motorola symbol and no mirroring option than a day latter I tried again and it worked. Not sure why.
Have you tried cycling through your tv settings once and than back to hdmi?
i dont know what happned. i decided to reflash the current stock through rsdlite and im now able to mirror and use my kickstand again so im happy now ill root and see if thats why it stopped working
Hi everyone. I just got my RAZR and have been fairly impressed with it, a big upgrade from my old SE X10.
I ran into a couple of issues though... I couldn't use the camera (no visual input from the camera, just black with the camera app overlay), and there seems to be a persistent HDMI alert, even though I haven't got a cable plugged in.
A factory wipe allowed the camera to function, but the HDMI menu is still there.
Any ideas?
I'm having the same HDMI issue. Seems to do it mostly when some form of media is running (XM radio app for me) and you move the orientation of the phone. Only started doing this recently though. A couple days. Coincidently around the first time I actually used the HDMI out. Any help would be great as this menu is very annoying and doesn't need to be running.

I talked to Rogers and they're sending me a new device. It seems if i press lightly on the "M" in Motorola, the menu goes away. Must be a loose connection.
Ok, scratch that. It's doing it all the time now. It goes in and out of thinking an HDMI cable is connected. Also, it seems like since this has been happening my once great battery life is now diminishing, and is running slower, lags in answering phone calls, and also the camera issue is happening... but only when it thinks an HDMI cable is on.
On an interesting side note. it seems i've found a sweet spot. When I press on the edge of the phone directly above the two tiny light sensors under the "M" it goes away. When I release it, it immediately thinks the cable is connected. I can only assume that it's a bad connection on that port to the main board. I've never used the HDMI out until about a week ago and that's when the problem started.
Hey all.
I've been running ICS ever since the leak came out (one-click install), and it's been really great. Few bugs here any there but they're mostly small.
I recently received 2 MHL adapters that I bought off of Amazon (one to leave at home, one to shove in my bag for travel) and when testing them out I found that most of the time when I had a screen connected it was just solid black.
I say most of the time because there were a few apps that actually output to the screen (Crayon Physics, built-in camera app, Camera Zoom FX), but just a solid black screen with any other app or on the home screen or in the settings menus.
I tested with both adapters multiple times. Made sure they had power connected to them (used the stock Samsung charger that came with the phone). The HDMI cable is good (used with my computer). Made sure USB degugging was turned off (and when that didn't work also tried it with it on). Since I actually was able to get some output from the adapter I'm assuming the problem wasn't with the adapters themselves.
Is the ICS leak just currently incompatible with MHL adapters? Is there a fix available?
ive had my MHL cable for over 2 weeks now and its got the official samsung logo - and i got it from suntekstore... only problem is i havent got it working...
ive tried with my dads stock 2.3 i9100 on a viewsonic monitor and samsung tv
same with my 4.0.4 i9100 resurrection remix 1.7 + siyah 3.1.2
the other two items i got from suntekstore were 2 OTG adaptors which fail to work... (i also have one that does work from another store) so i think it might be the MHL adaptor itself
yesterday i was frustrated and kept plugging my phone in and out of the samsung tv.... and BAM i got a visual =S after like 10 'no signal' and 2 resolution not supported... but the screen was stuck in portrait... thats the closest ive come to using MHL properly!
on top of that... when i use OTG keyboard connection... the phone freezes if i try pressing caps lock to check for power on my phone! any one else running same OS version and its working?
When successfully connected via MHL the S2 will display in portrait, so that was normal. Apps that run in landscape will do so when run, or where sensor orientation works, like in photo gallery etc, you can rotate it to landscape yourself.
No, as for your issues regarding getting the picture to stay on; first, you did have the Samsung Charger plugged into the MHL cable right, and the correct output channel selected on your tv?
Assuming you did for both the above, the problem is likely with your hdmi cable, not the tv's. Have you tried using different cables? I have a problem with one of my hdmi cables where the screen goes black for a few seconds whenever it pleases, with another cable (which comes with the sky box), it stays on all the time. So try changing cables and see what kind of response you get.
Also, some users have mentioned that they seem to get picture when they put their phones into flight mode first, I've never needed to do this, but give it a go and see what happens. Once you've got your picture up, you can use your tv's remote the control your S2, assumming your tv supports that function.
Hope that helps
I have not tried that rom but last I heard any source based rom doesn't have a working MHL output. I don't know the status at all of OTG on source based roms.
You said you tried it on your dads stock phone but didn't clearly state if it worked or not which it should if the phone is stock. So use that as a basis of if the adaptor is broken.
thanks guys - yeah it could be the hdmi cable... they are pretty cheapo - but on seeing 2 OTG adapters from the same store dont work... the MHL being broken cant really be a coincidence? it was in delivery for over 1 month =[ maybe someone broked it! lol
I think in the end it was the MHL adaptor... ive got a replacement sent out as now the phone wont even recognise power to charge when plugged into the mhl however the charger directly into the phone works! argh may be a long wait for the replacement took 30 days to get my other shipment! may have to resort to a more expensive one
I have tried HDMI out on 3 TVs and it only works on one. The one it works on is the newest one by a few years.
On the other TVs the results range depending oddly on the cable. A $30 Rocketfish cable I purchased for testing and now returned resulted in zero output on the other two TVs. My cheap cable will make some crackling noises and the screen will flicker on and off.
No output at all through my my receiver.
On the third TV... a 2012 model I believe, it works great. I have never had any issues with HDMI out on the other TVs although I only use an older laptop and a PS3.
Any clue what might be going on? Do I have a bad device or are my older TVs not compatible for some reason with the Tegra 3 HDMI out?
Thanks.
I finally got through to Hisense support. Major PITA as they disconnect you after a minute or so of hold time. Not like I expected anything different. Regardless they guy had no idea about any issues.
I'm going to go and buy another from Walmart and see if it has the same issue or not.
Went and bought another one to test the HDMI out with.
Same issue. So this tablet has problems with some TVs. Searching a bit further it seems like some android devices regardless of manufacturer have HDMI out compatibility issues.
Chromecast should hopefully solve this issue anyways.

Chromecast works great with this tab. Havent tried the hdmi yet.
I've seen some strangeness of a different type. When I plug my Sero 7 Pro in to one of my TVs with a particular cable, the touch screen starts acting funny, meaning a touch registers as a swipe and we'd things like that. Anyone else seeing weirdness like that?
Thanks!

HDMI issue
I am having an HDMI issue. For me, whenever I connect an HDMI cable to any HDTV and use Adobe PDF Reader while scrolling and zooming in I get all kinds of artifacts and glitches on the tv screen but not the screen of the tablet. I've used two different tvs and they both react in the same way. These jagged lines appear on the screen while zooming and scrolling but disappear right after i lift my finger off the digitizer. I haven't tried many other apps but it seems like its solely Adobe PDF Reader reacting this way. The few other apps I've tried do not react this way.
Would this be caused by...
The tablet itself?
The current software/os version?
The hdmi cable?
The tvs?
Model number: M470BSA
Android version: 4.2.1
Kernel version: 3.1.10
Build version: P756.6.02.11.00
I just bought the tablet a couple days ago and was notified of an update, P756.6.02.20.00. Should i go ahead and apply this update? or has anyone experienced this issue before and found a remedy? Any help regarding this minor but annoying issue would be greatly appreciated.
Different cables with less or more quality is not odd at all really.
I would not be surprised to find out that all your problems are from the cable you used and/or the tv you tried to use and not the tablet.

There are definitely issues with the Sero 7 Pro and older TV's via HDMI out. In my case, I'm lucky enough to get a picture on the screen, however it fails back down to 480p which is just unacceptable.
With that said, there is some hope. The issues that I am experiencing do not seem to be directly tied to a hardware problem, but rather software. Via rooting and trying a custom rom, that is not based off the stock rom, I was able to get a 720p picture on screen though there are other issues

I have a small, cheapo TV that causes problems with my touchscreen whenever I plug in the HDMI cable to my tablet. Plug it into my big Samsung TV and it works great! Weird, eh? The small TV causes the touchscreen to register taps as swipes..

The touchscreen being erratic happens on a few of my other older devices with HDMI & MHL connected too. It seems that most of these haven't been tested extensively in this mode. There's a ground connection problem, I remember it was better if I connect a charging cable also, or holding it slightly differently or setting it down when using the touchscreen & HDMI connected.
Erratic screen problems
I almost returned my tablet today. I have three of them and only one exhibited erratic behavior while using HDMI out.
The screen would barely respond to my touches. It would misread and select the wrong things. I couldn't play games or scroll the screens. A mouse would work but not touching the screen.
It turns out the erratic screen problem goes away if I turn off the Sony Playstation 3.
This time I tested it and it is repeatable. I had both the cables plugged into the TV next to each other so now I separated them.
Now that I think of it I remember seeing a video about a guy who thought he had screen problems but it was interference from a nearby computer.
I found the video I remembered of the guy who was having the same problem due to interference from his computer. He demonstrates the erratic screen behavior and says he returned his tablet twice thinking it was faulty.
I can't post the link...oh well. You'll have to look it up.
