I have a Moto x4 with Android 8.1. Android Auto works, but if the phone reaches 100% charge while Android Auto is active, it gets disconnected from the car and a red error exclamation comes up on the phone. The only way to get it reconnected it to unplug the cable from the phone or car and plug it back in (which is obviously impractical while on the highway). It will then disconnect again within several seconds as the battery hits 100% again. To use Android Auto, I have to remember to discharge my phone before trips. Honda suggested I take it to the dealer and have them test it with "a bunch of phones they have on hand", which I suspect meant "ask everybody in the shop to hand over their personal phones". That kind of test will take a long time given I have to wait for every one of those phones to get to 100% and see if the error happens, so I'm asking here instead what phones anybody else has experienced this with. Is there some common hardware or software version? Sorry if this has already been posted, but I can't find a thread. I've seen other posts, but counting internet posts is hard, so I put a poll on. Regardless of answer, listing a phone model would be helpful.
