Can someone with working MHL-HDMI adapter confirm this?? - AT&T Samsung Galaxy Note I717

I got my MHL-HDMI cable from Amazon for $10, it's the one listed in the ultimate accessories thread in this forum. It is not working well for me at all, lots of flickering and going blank.
As I understand it, MHL should mean that the phone should be in USB Data/charging mode so it can pass data to the MHL adapter, am I right in assuming this???
If so then the problem may be that the adapter isn't communicating properly with the phone and it's bouncing back and forward between AC Charge and USB mode which would cause all kinds of problems.
Can anyone with a solid, non-flickering MHL adapter check their battery status in 'About Phone>Status>Battery Status' and tell me if it reads AC or USB mode for charging when they are mirroring over MHL HDMI??
Mine reads 'AC charging' and plugging it in I get horrible screen and audio flicker and the screen resolution seems very low. I have the AC power plugged into the MHL adapter and I plug that into the TV first THEN plug it into the phone.
It's pretty much unusable like this, seems like a lot of people are having the same issue with many Samsung phones and tablets.
Anyone resolved this on their note????

Did a little more testing and noticed something that I think may be odd, wondering if others can confirm.
I checked my battery charge status while plugged into the MHL adaptor and watching the picture flicker on and off on my TV. It read that I was charging in "AC mode". If the phone is in AC mode then surely the data connection to the MHL adapter wouldn't be working and the phone may be pulling too much power away from the adapter for it to work right??

Just wondering if you figured this out. I got the mhl adapter yesterday but the screen flicker makes it unusable.
Figured out that the flicker only happens when wifi is on. When I switch it off its smooth.
Is this the same for you?

Working for ME
I have the ATT Version of the Phone ... and it didndt come with the MHL Adaptor
http://www.google.com/products/cata...=X&ei=zczLT8GLCIOG6QHJhpjtDw&ved=0CJABEPMCMAA
The one I am using is from my older Samsung Infuse - ATT phone also!
I had that working BEFORE with Infuse , and works just as nicely with NOTE
I have the cheapest HDMI v1.4 cable - nothing fancy ( pack of 3 = $5.00 - free ship) ....
The only thing I am P*** about is the in INFUSE - all video's you can load ( 1080p) in mp4 ( borrowed from Itunes etc) with DIRECT TRANSFER ie the infuse didnt go thru any 'conversion' before addin to phone.
In NOTE - the same file - note wants to convert to 'mv' - and in my view = this making it NON 1080p format. Since my NOTE is rooted& unlocked , i can and able to by-pass that conversion C***..
.NOTE = does go into "charge mode' when you stop playing videos/ movies ( I have 64GB sd card ( formated for 32 apps +etc and other 32 GB for movies /videos

Ausmike or anyone else: does your note only charge when using this adapter and not streaming video? mine eats up battery when playing video and streaming and it pisses me off. Why couldn't samsung just used a simple mini HDMI or something similar

Kidigi MHL HDMI cradle

Well.. I just received my Kidigi MHL cradle with excitement
Two things... it pees me off I cannot use the cradle WITH a case on, like the other Kidigi cradles (ARG!!!! - The pic showed a phone with a case on in the cradle!), and then I discover that the AC Adaptor is defective (loud buzzing when there is no current draw.)
I'll try the HDMI in a bit if I can.
OK, what am I doing wrong here... plugged in, HDMI cable plugged in.. but screen not showing up.
Do I need to activate any special application or something?

My Samsung tv didn't like the evo 3D's HDMI (worked fine with my 4G). I ended up routing the phone to my yamaha amp's hdmi then to my tv. Maybe try another tv or device.
It's got a built-in MHL adapter? So you can plug an HDMI cable right into it?

Yes, apparently so. http://www.kidigi.com/product_lv2.php?pid=1316
Typically doesn't say 'mhl' in kidigi's page though.. but did on ebay.
I have ordered another HDMI cable (v1.4a) just to be sure... but as the ac adaptor is making an audible buzzing, I'm seriously likely to send it back anyway.
I was previously using an HDMI to DVI cable with this, and it didn't work at all. So I ordered a V1.4a HDMI cable instead.
It is most odd, because it seems to work intermittantly. The monitor keeps blacking out for a few seconds, and then working fine for about 20 to 30 seconds.. then blacks out for a few.. then works for 20 to 30 secs....
Not sure what to make of that really. Maybe the auto-rotation is messing it up a bit.. will have a fiddle with the settings.
And now it seems to be working just fine. I had made sure cables were pushed in... maybe the rear wasn't in enough.
Apart from that, I had changed from 'charge only' to 'HTC Sync' (whatever that is), and the phone is now fully charged in the cradle.

How does it look on your TV? What size is your TV? I bought two MHL adapters and NEITHER work on my 61 inch Samsung DLP, but they work on my mom's 19 inch HDTV. However in some areas the picture seems to have a faint checkerboard pattern, especially when scrolling through the gallery. You notice this effect at all?

I will have another look tonight. I'm viewing it on my 26" monitor. Image looks a little grainy I remember, but that's due to it being on about 720p rather than 1080p I believe.
The auto-rotation is a bit screwed up when it comes to 'dock mode' though. You enter docked mode, it displays in portrait, but then when the weather gets displayed it only shows the weather animation and goes into portrait mode (even though the phone is still in landscape), so pushes things off screen. I have no idea why it does this.
My O2X HDMI output is flawless. TBH considering the amount of *****ing the O2X got (even by owners), it's a phone that works very very well.
If I can get the 'issues' sorted out I'll look to get an android bluetooth keyboard and mouse
I have the same dock and the problem is it only charges with 500mA. I made a Tasker profile for a Desk Clock and when the screen is on, the net current is like +2~20 mA (practically zero) So I did the charger mod (soldering together the data pins) on the AC adapter and now the AC adapter itself can charge the phone with 1000mA but the dock itself presents itself as USB and falls back to 500mA. I will either try hacking the data pins on the dock or patch the kernel to allow for fast charging. I have to look into it more though, MHL portion might stop working with data pins crossed.

For a dock that I might have the phone in for a while, i would prefer it slow charging anyway. Means device should be cooler.
I do not have a cradle but my MHL adapter does suck battery and a dirty hack to maintain battery would be great.

mhl headbang

I've tried the several listed proper sequences, I've tried USB debugging on and off, and I've tried rebooting my phone repeated times. I have the Menotek adapter others on here have said they've had luck with... but no matter what I do, neither the phone, nor the several TVs I've tried it with have recognized each other. I feel like there must be some setting or program I'm missing. Please help.
I get sound, no video
Sent from my SAMSUNG-SGH-I717 using XDA
My phone is the att stock version. I have the menotenk with rcp and it works every time I use it on a HDTV but if i use it on a dvi device I have to use headphones or any audio cable in the headphone port or at least use a bluetooth audio other wise I get video that plays about a frame every 3 seconds and no audio. If I am not watching a video it will work fine... but that don't seem to be your problem.
Debugging should be off. This is my procedure:
*Make sure you hdmi cable is already connected to the tv. For things like RCP most tv will only work on hdmi port 1, so just to be sure use port 1 on your tv and make dobule sure you are using the right cable for the port.
* Restart your phone, do not load any app that does not load automaticaly.
Make sure tv is on and set for whichever hdmi port that you intend to use.
Hook hdmi cable to your adapter.
Connect your charger to the adapter. (Most tv's will have some sort of reaction to this. My small tv goes from no signal to no video when I do this, my 52" goes from a blue screen saying no signal to a black screen, this might not happen on every tv but if it does in your then you can guess that connection is good.)
Connect the adapter to your phone. (When this happens you should see the charging icon in your phone, also, you will see a message that says something like "hdmi connected", I can't remeber off my head)
In a few seconds you should see your tv flicker and they you should see video and have audio.
Before I got this menotek I bought another brand and it was touch and go with that one, I had to try the above procedure a couple of times and sometimes it would work, most times it would not....
If you are stock and it don't work I will have to say that you have a defective unit.
Sounds like a hassle to me.
I'm on stock firmware using the OEM Samsung MHL adapter. I simply pull the HDMI out of my PS3, and plug it in to the MHL adapter. Then I plug in the power supply. Then I plug the MHL adapter in my phone. Works flawlessly every time...tested on multiple video apps and games.

Hassle? How so? Sounds like the same thing I do.... I'm trying to help the op, telling him how to connect it probably will not do, If he is reading the instruction on the adapter he is alreading doing that same process, I'm trying to give him a better picture than the instructions on the adapter documentation.

[Q] MHL being wierd and OTG crashing phone

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

[Q] Charging Issue - MHL/HDMI Adapter Samsung s3 lte

Hi All,
I was wondering if anyone had any insights in to this problem I have been having.
Briefly, I have the 4g lte verion on EE's new network. I purchased the official MHL/HDMI adapter which works fine and the video is outputed to my sammy 50inch tv fine. The issue I have is the battery drains while doing so. I belive this may to due to the phone outputting more than it is drawing from the power source. Any thoughts ?
I spoke with Samsung tech and they said a number of people have started to report this issue and they are currently testing/investigating. If this is indeed the case seems a pointless acessory as a long video would possibly drain the whole battery, Im yet to test the full drain time.
Secondly, with a 3rd party docking cradle with spare battery slot which purchased from amazon (http://www.amazon.co.uk/eLifeStore®-Samsung-Desktop-Charger-Docking/dp/B008PPRGFY) also does not charge phone properly. Even with the orignial charger in the ac port (or usb port) . The phone reports as charging but stays the same or decreases. Charged directly from the socket it is fine. Strange!
Any help or thoughts would be greatly appreciated.
Thanks
Ian
It's common. Mine did that too! I switched to my old S2 charger, problem solved
Thanks Ill try that out, any idea why that works ?

No idea man? A design fault maybe? All I know is that my phone took for f#*%ing ever to charge with the USB type wall charger. I pulled it out of the socket and plugged my other other one in that was sitting right next to it and it started charging? Checked a few minutes later and it had climbed considerably so I pulled the USB cable out of the new plug and kicked it under the bed where it now lays resting not to be used again LOL.
USB plug/cord works perfectly fine? So I use it on the computer. My laptop even charges the phone via the USB cable faster than the socket plug (which is usually the opposite - as I am sure we are all aware). So yeah I would say poor design or defective wall plug or both or something? Wasn't going to send my phone back because of it. 2second decision problem solved Samsung phone is great!
Im having exactly the same problem.
I have an s3 on orange and have the same mhl adapter conected to my tv.
I have tried the charger from my s3 which does says its charging when I connect my phone but only for about a minute so I also tried using the charger from my s2 and that just does exactly the same.
An easier way is to buy the official allshare dongle for your hdtv then you can stream anything from your phones screen direct to your tv and can have the phone on charge via pc or wall socket at the same time,
Hope this helps
i suggest you throw away your original charger (slow charge) and its usb cable (loose - actually caused the extsd to become damaged to the point i had to repartition) and buy yourself a cheap usb cable for data (£2) and a 3rd party charger (pref not a usb adapter one - £5) and all should be fine!
I still experienced a small battery drain while using the mhl adapter, however, i froze a few apps with titianuim (ones i know run all the time like utter and tasker, paragon ntfs, easy ums, directory bind etc), and put it on min brightness - works like a charm. I know its a effort freezing apps but does the trick with my phone... Since finding that out i actually keep paragon & easy ums frozen till i need them...
just a few thoughts for you....

Galaxy S8 HDMI not working

I bought the ADAM elements CASA H01 USB Type-C to HDMI Adapter Gold, I tried connecting HDMI to my S8, S8 says HDMI connected but the TV has no response. I am sure the TV works with HDMI as I tested my XBOX on it. Is there anyway to make it work? Or is my adapter broken?
you can try things like switching the tv off/on and the phone off/on whilst its connected. sometimes, not often, that will help
it sounds like hdmi handshake issues. basically a compatibility problem between the phone and the tv.
Thank you for the suggestion, I tried but still doesn't work. If it's a problem between the phone and tv, should I try the adapter on other tv?
I used Choetech USB C to HDMI 60HZ cable to my S8. Everything worked well. https://www.amazon.com/CHOETECH-Thunderbolt-Compatible-MacBook-ChromeBook/dp/B06XP9NV4G/ref=sr_1_5?ie=UTF8&qid=1495422430&sr=8-5&keywords=choetech+HDMI
I had some HDCP issues when I tried connecting my S8 to a capture device, but that was due to a poor quality cable.
Make sure your device can read the HDMI signal coming from the phone too. It appears to send 1080p or higher, so if your device only understands 720p (some smaller TVs are like this) it might not be able to see the signal from your phone.
I'm having same issue hubbies works mine won't same cord and tv???
Any idea what's going on I just factory reset my phone and still doesn't work
I just got an hdmi to USB c adapter today as well and I first connected it it did not recognize my phone either. The thing that seamed to do the trick was attaching the adapter to my phone first without the hdmi or power cord, then powercord then connecting the hdmi cord and all works well
still not repaired
4 repair invoices 3 months and still not repaired currently on hold with Samsung .... i'm not impressed as this feature was a huge decision for buying the S8+
i use baseus usb-c to hdmi cable - all work good (but no dex)
I have tried two different usb-c to HDMI cable adapters and can't get neither of them to work. Any ideas thanks
Broken and need help
I have a Ugreen Adapter for usb-c to HDMI cable, it worked very well
On several tvs, it WAS working here in Mexico on my ATVIO tv, then I did some phone cleanup and it STOPPED, is there a special application or setting that I've uninstalled????, I'm lost without YouTube on my tv LOL , cant find info anywhere and I swear I installed something on my phone to get it working like 7 months ago in Dallas LOL
biggest thing iv found with EVERY usb type C connectivity issue, POCKET LINT. its as simple as using a sewing needle or safety pin to CAREFULLY take the pocket lint out of the type C port on your device, there are 30 individual pins in there, and they ALL need to make a good connection to your adapter. brand does not matter, if it works with phone A phone B will figure it out (unless your phone simply doesnt support mhl adapters)
Same problem - Galaxy S8+ with Choetech USB-C to HDMI adapter. Worked a couple of months ago not working now. Wife's phone (exactly the same) work a with adapter and HDMI cable. Cleaned, powered on/off, reset phone, nothing works. So frustrating. Any ideas?
I was using my S8+ with my TV. After a couple updates ( prior to Pie) no longer worked. Please don't suggest turning things on / off or factory reset.... The cord is fine. My phone just now updated to Pie, I thought great, maybe it will work again..... nope... I've contacted Samsung, same BS runaround. Samsung - must be a compatibility issue, Me - it was working, Samsung - must be the cord, buy a new one, Me - already did, tried two different brands, Samsung - was one of them Samsung, Me - ......., Samsung - try factory reset, Me -....... by this time I know I'm screwed. There WAS something to do with an update. (And yes prior to the Pie update I did a factory re-set with no results). From the comments on this post appears no one has a solution....
