[FYT Android Head Units] dishe2:
A while back I mentioned that my Atoto S8 Ultra (uis7862) would randomly reset on me. I owned it for about 6-8 months before this happened the first time.

The internal storage seemed intact (files in the downloads folder, application data folders, etc could still be found in the file explorer), so it's not like the storage chips failed but the unit's OS was returned to stock. All apps, settings, etc were gone.

I figured it was something I installed or did until it happened again, and again, more and more frequently over time.

Atoto gave me different things to try, updates, avoiding launchers, etc, but inevitably it would reset every couple of months, then every few weeks. I even left it completely stock to see if it was something I was using and it STILL reset eventually. When it got down to 2x in a month, I pointed out it must be some sort of hardware failure until Atoto agreed to send me a replacement.

The replacement went in about 6 months ago and it didn't hard reset on me anymore. HOORAY!

Until last week. All my settings and apps disappeared, backup camera lines, etc. The internal storage has signs there were once apps installed, but the OS is oblivious to it.

I'm livid. Atoto is reluctant to send me another one until we determine it isn't something wrong with my wiring.

The fact that both units seemed to work fine for at least 6 months implies it isn't something wrong with my car's wiring, right? I mean, if there was an intermittent electrical problem, it wouldn't happen frequently and then PAUSE for the first 6 months of owning the hardware, right? Both units seemed great when they were new, which implies something is slowly dying over time internally. Here's the thing- I'm in a Reddit and FB group for Atoto and plenty of people have the same model as me and I've only heard of 2 people it happened to. Sometimes you get a lemon, but what are the chances I got 2 lemons in a row? I can even see the replacement one was made more efficiently (the metal parts in the back appear to be a newer manufacturing process, different shaped heat fins and screw placement) so it's not like I got two from the same production run or something.

Here's some interesting information I've gathered:

1) A user on facebook says apparently if you have a Toyota (which I do), sometimes the SWC wires on some harnesses can cause a problem that makes the unit reboot. (he says it can short it out and cause this but I doubt a resistive button short would cause a hard reset)

2) Atoto's support say the unit is designed to hard reset if the forward button is held down. This is a fail safe apparently in case you get locked out or something and need to hard reset. I feel like this should have been a button you have to reach from the back or something, but no matter. I'm not holding any button down, so that can't be it, but it's interesting to note there is a routine to suddenly wipe everything built in. I wonder if this is true of all FYT radios. But suddenly this makes me wonder if #1 above is somehow getting triggered by a weird phantom button press.

I don't know where to go from here. I feel like I have to troubleshoot this myself because Atoto won't be able to figure it out and I don't want to keep getting new radios every 6 months.
