HDMI output not working after Kit Kat Update

[AC Question]

Is anyone else having an issue plugging in your phone to an HDMI cable after the update? MyHDMI out just stopped working after the update. No other issues except for SMS smileys since the update.

I received the 4.4.4 update on my HTC One M8 and the HDMI works BUT it is squished with about 5% blank spots at the top and bottom on my JVC car unit with MHL.

Clear the cache partition.

Cleared cache.. Nothing changed and still doesn't work.

Exact same problem. 4.4.4 broke HDMI output, I had full screen HDMI on my appradio before the upgrade with no other hardware changes. Now I have to figure out how to roll back to 4.4.3

PS, I did a cache and davik cache partition wipe with twrp didn't help.

Traded in my Samsung note 2 for the droid turbo, which has 4.4.4. My mhl adapter setup in my truck no longer works. VERY bummed by this, never even thought to research this capability, just assumed it would work. Assumptions start with ***, dang it.
I'm on Verizon.
If anyone comes up with a fix, I'm all ears.

same case here.
i am using HTC m8 and i spoke to the guys in HTC Malaysia, they have no clue as well..
from the sound of it, sounds like a patch is needed and there's only a very small number of user impacted or at least reported..?

Same thing here but whith a Lollipop update, not Kitkat. I have this adapter working really nice with my LG Nexus 4 until last Android 5 OTA update reached my phone.

I found a solution, you need to buy an adaptator micro USB 5 pin to 11 pin as for galaxy S3

It works too for galaxy tab 3 !

Hi everyone, the hdmi output to tv not working due to kikat issue, not the mhl , not tv. It only work with jb 4.1.1 . Or 4.1.2

 

[locone]

Only way to get it fixed is downgrade to jb 4.1.1 or 4.1.2 kitkat not allowed hdmi to tv.

Note 3 here... same issue with 4.4.4. Used the same cord on Galaxy S4 with 4.4.2 and it works. Anyone know if this is getting looked at?

 

[Chris Amaral1]

I've had same issue for about a year.
using app radio/hdtv.
only way it works is to not use charger at same time as hdmi plug.
Works flawless exept for battery drainage

Now I know what happened! I have this all set up in the car and then after a forced EFFING update bam. Nothing. I will try to disengage power supply back to the 11-pin hdmi mini plug. But I need power for the hdmi signal. Why can't at&t stop screwing with us? Damnit!

Hi, everyone I have the same problem called t-mobile and Samsung directly. Tried all of your suggestions first but didn't work . My phone provider or samsung were not able to help either. I think it's their way of getting us to purchase new phones. I bought 3 wires from best buy and also bought a pioneer radio for my car because I was able to connect my phone. Spent over $800 between radio and wires. Please help.

Re: HDMI output not working after Kit Kat Updat

I was able to connect my Samsung Note 3 to my Samsung TV via my MHL to HDMI adapter and cable a couple of months ago. I tried again for the last few days and I get a message on my TV "No Signal" when everything is connected correctly and "No Cable Connected" if I unplug the micro USB power cord to the adapter. I also have 2 different MHL adapters I have been trying. When I called Samsung customer service today, the girl on the line told me that my TV is not capable of being used that way. (Um...WTF?) She laughed at me when I repeated that I connected them together before, and insinuated I was lying.

Here are all of the things I have tried so far.

1. Verified the HDMI cable and the HDMI tv port was working by connecting my Xbox 360 to the same TV, cable and port.
2. Was able to connect my friends Samsung S5 to the same TV, cable and port.
3.Tried downloading several apps from the play store including the ScreenMirroring plug fix. None of them worked.
4. Updated my Android version to 4.4.2.
5. Put my phone in "Safe Mode" to see if it might be a 3rd party app, but that didn't work either.
6. Deleted all 3rd party apps I have downloaded as well as updates to other apps I never used. Nope! Didn't work either.

I don't have WiFi or cable so I can't use any other devices.
Are there any other suggestions any of you can think of for me to try? Is it possible to remove an Android update without doing a factory reset and deleting all of my family pictures and videos?

I have the same issue with my Hudl 2. In "settings" HDMI area all options are greyed out. I am able to cast the screen wirelessly as a work around but it would be nice to have HDMI functionality. Tesco Tech help is as often the case useless.
