This is what my 8" screen looked like on 10-21-17, black & totally unresponsive (but radio worked with steering wheel controls):
It has acted normal since, but I'm concerned it will fail after my 3 yr. warranty ends.
Also, Pandora has been glitchy lately (with samsung S8+). It works for about 5-10 min., then freezes. And, I must turn wi-fi off before I start driving or it won't connect at all. On a good note, android auto works well.
Update (12-2-19): It is working fine, so far, so good, fingers crossed.
