[Android General] Pig Vomit:
Been a couple weeks so thought I'd post an update.

Here's my setup:

Stock (except root/SuperUser) Nexus 5 4.4.3 ART (ART never caused problems for me on 4.4.2 or 4.4.3).

Analogix Slimport Adapter: http://www.amazon.com/gp/product/B00DWGB6CU

USB Firewire Micro-USB Extension. http://www.usbfirewire.com/Parts/rr-mcb-ext-xxg.html I'm using a 72 incher. It is VERY important that if you are using an extension with Slimport that you get a 5 wire version. I initially bought something at a local store advertised as 5-wire, it was not, it never worked, and this caused me big problems and frustration.

First of all, thank you to Area51 for developing the app and being pretty responsive to people in this thread. I can't thank you enough.

The ARU, phone and HU combo takes a bit of practice to figure out what's going on, what works, what doesn't, what quirks there are. So, if you are new to the app/installation as I was a few weeks ago, if you are getting your phone's homescreen on the HU at all, please take time and try different things, different versions, etc., live with it for awhile, and eventually you will figure most or all things out on your own. I know, I know, we all want it all NOW, right? I did. Patience is hard.

So...after a few weeks now, everything for the most part is working well. Had a number of problems, everything from figuring out how to get the phone aspect correct on the HU to problems with my soft buttons and everything in between. Also, like others have posted, no Screen Standby on Nexus 5. I can live with that.

That having been said, there are still a few quirks I can't figure out, so I'm asking for a little help.

First, to Area51, I couldn't find anything about this in this now rather massive thread, so forgive me if this has already been brought up. The phone's soft buttons on the HU do not work on version 16. However, the soft buttons on version 15 work consistently. I've noticed that within the first few seconds in the connection on version 16, I can hit a soft button and it will work, but then will not work a few seconds later, while the rest of the touchscreen works just fine. Calibration is not the problem here. Have to default to using the soft buttons on the phone's screen. It's only the android/Nexus soft buttons on the HU that don't work.

The other rather consistent and more frustrating problem I have is that I can't quite seem to figure out how to get touch on my HU to work consistently. Very frequently, at least 50% of connections, I will get the picture of the finger with the red X when I touch the HU screen. Other times it works flawlessly (except for the soft buttons on version 16). I've tried connecting things in different order, noticed that having it connected interferes with the Sirius tuner somehow ("Check Tuner" error on HU screen), don't try to connect when HU in in Bluetooth Connection mode, but I just can't seem to get it to work consistently. If someone could offer some guidance here I would greatly appreciate it.

Thanks again to everyone who tries to help at xda.

May I ask where you bought the MHL adapter? There are tons of fakes out there, and if you bought it somewhere other than Samsung (I'm looking at you, eBay, and all non-Amazon sellers on Amazon) there's a chance that the adapter could be the problem. Have you tried the MHL adapter on your TV to see if it works? Are you sure you bought the MHL adapter specific to your phone? Samsung has released unique adapters for specific phones. I'd double check this.
