[Galaxy S III Q&A, Help & Troubleshooting] Olywa123:
j0ep0, walkeryan, great that you two will work together to improve this and thanks to you both for all the effort you are putting in.

If a new development thread is started can I suggest the following wishlist/order for the areas for improvement (really just a summary of what is already here in the thread), of course I leave this up to you but thought it might be useful to capture everything:

1) Compatibility with other devices – the more members that get to enjoy this the better.

2) Home button fix – Home button not currently working on headunit display (take you back to drivelink home instead of launcher home).

3) Removal of the warning/caution screens so the we load straight into the drivelink homescreen (or better still, straight to the launcher home screen if ever possible).

4) Lost connection/Memory Issue – Sometimes the connection is lost because Drivelink or TMServerapp are being closed by the OS when no longer in the foreground. The issue can be reduced significantly by running apps like ‘Smart Ram Booster’ but it would be good if there was a way for Drivelink/TMServerapp to maintain a high priority in memory.*

5) Phone screen off (no need for it to be on if duplicated on the headunit).**

6) Compatibility with other launchers - currently restricted to using Nova launcher to make this work - would be great if working with stock or other launchers too).

7) Remove the need for ‘drivelink’ altogether (perhaps a bit of a dream this one but having a smaller app with just the necessary code and being able to make the connection without the clumsy drivelink app altogether would be amazing).

*Regarding No. 4 - There are some memory tweaks suggested by j0ep0 here: http://xdaforums.com/showpost.php?p=32829363&postcount=240 (I have to admit I have not yet tried these as I will move from ICS to JB shortly and so will investigate then).

**Regarding No.5 – Phone screen off – some things that may make this more difficult, in using mirrorlink I have when running a non-stock apps experienced the phone screen go off, you’d think this would be a good thing but it actually means the phones lock screen kicks in (and is displayed on the headunit), it then cannot be unlocked from the headunit because you first have to push the power button on the phone so that it wakes it. I guess there is also a danger with the phone screen off that the phone eventually goes into full sleep altogether (although I would think that would be prevented if music is being played or during a call).

For those that have a working set-up I’d like to recommend the following apps...

Assist Key (Temp fix for home button in Drivelink) - There are many apps which add 'virtual' keys to your screen to help prolong the life of your phones physical buttons - 'button savior' and 'softkeys' are two popular ones that work well and have lots of functionality but they bring up a small menu of buttons upon pressing and I was looking for something that just required a single press and was much lighter. After trying out several I found a free app called 'Assist Key' which places a small transparent 'home' button as an overlay on top of any screen/app you are in, you can define the location/size/transparency. This runs nicely on top of drivelink and takes you to Nova launcher home with a quick press. For anyone wanting to try this - the button by default gives you a pop-up bar with several keys, go into the apps settings and under 'action' select 'only home button', now just one press on this virtual button when in drivelink takes you to the launcher home and can be operated from the headunit. https://play.google.com/store/apps/...lt#?t=W251bGwsMSwyLDEsInNoYXcuYXNzaXN0a2V5Il0.

Google Car Home – A simplistic large button interface where you can add shortcuts to your favourite driving apps (preferred music player/Navigation software/contacts, etc.), there are nicer looking apps that do the same and offer a little more functionality available on the Play store but I chose this one as it is very lightweight (important because of the memory/lost connection issue mentioned above). For some reason it is not available to everyone on the Play store but can be found here: http://xdaforums.com/showthread.php?t=1569027

Car Tunes Music Player - This has the best voice recognition of any music player I’ve tried (voice commands for selecting by an artist, by track or by album name and really very accurate recognition). It also has a nice simplistic interface that works perfectly on the headunit over mirrorlink. Go for the free version (there is a paid version but it offers little benefit over the free one). https://play.google.com/store/apps/...DEsImNvbS5oc3RhbmFsYW5kLmNhcnR1bmVzLmZyZWUiXQ..

Lastly, for those that do now have full launcher homescreen/all apps working and mirrored on their headunit thanks to the info/modified apps in this thread please do consider making a donation to these guys (j0ep0, walkeryan) as they have put a lot of work into this for us :good:
