I actually use Waze which doesn't appear to support split screen ATM. What I really miss is the weather information overlayed on top of the AA display which looks to be fine with coolwalk. Do you know how to get that back?
Yesterday I browsed about Coolwalk and found somewhere/something about that missing Weather info
Seems to be a bug (then, why Google did not akready fix?), and that it works in AA portrait mode (who on Earth has a portrait infotainment screen?)
Google for more info
I think I've seen in the AA AIO Tweaker some patching options for disabling Coolwalk (I'm no more sure, I stopped using AIO Tweaker)
But frankly, I have two phones, both rooted, with AA 9.1 and with the S2A installed the same way and on one phone (newer), in my same car, AA always works in the old mode without the Coolwalk/split screen
And I have Coolwalk as described only on the other phone
I cannot figure out what caused the difference but on my newer phone I installed AA earlier and updated through several versions till 9.1, and back in time used AIO Tweaker (and maybe patched to disable Coolwalk?!), whereas on that older/spare phone, where AA works in Coolwalk mode, I just installed AA/S2A recently when I additionally wanted to test something
