Bixby Voice prolonged CPU usage in idle

[hstpctech]

Hi,

During idle my phone suddenly got very hot, even more than regular gaming. It has happened twice, but this time I have the chance to check the app usage.

It turned out Bixby Voice got ahold of the phone radio and WIFI for over 2 hours, with the process called dexopt.

The phone lost 35% of battery in about 30 minutes or so. The first time it happened, I restarted the phone several times but it would just resume the mysterious activity. Eventually, I turned off the phone for an hour and it's gone. This time I did the same thing, turned off the phone at 65% battery power and recharge it back. After power up, the drain was no more.

The question: what is dexopt and what was it doing?

.dex means dalvik-executable but that’s as far as my knowledge goes.
Assuming that your Bixby settings are appropriately set, the only thing I can suggest is a cache clear for Bixby Voice, and perhaps the other Bixby system apps.
If no go, try Safe Mode.
If still no go, let us know.

I will give it a try, although it could be complicated since it has only happened twice, and I couldn't imitate the problem since it always happen during idle. Bixby Settings, I just use the default since I rarely use it. I do prefer it over Google's, though.

If it happens again, I will post it again, hopefully with more data.
