Hey there. I recently got my hands on the new phone 3a - works like a charm, beside the android auto connectivity.
either using wired or wireless connection, the audio - or better - the whole interface - stutters. And it is not like 2-4 times per minute, it is more likely a BT device getting closely to being out of range before a speaker disconnects.
what I did discover is that the stutter is always related to gui updates, such as the car on google maps is moving, rotating or the track seek bar is moving. sometimes the gui is frozen for like 1 second, then the audio stops, the gui refreshes and the audio continues.
with my 2019 motorola on android 13 this does not happen, using same connection and car.
What I already did:
-disabled the 3d maps on AA.
-disabled hw overlay in dev tools
-limited the screen refresh rate to 60hz
those three changes did make it better, yet quite not perfect as on my older phones.
What I could not test is sth. like using spotify / google maps in fullscreen, as my car screen does not allow fullscreen setting due to its size, I can only choose ⅓ ⅔ split screen view, where always spotify or google maps is the bigger tile - makes no difference.
I am pretty sad that the new phone with more ram and better chipset lags alot more like a 6 year old device. beside that I am pretty amazed with the 3a!
and ideas? thanks!
