I disabled anything to do with memory through xXx, as I've had WAY better success with Ex and EXKM. As far as memory goes, I changed a few little things in EXKM, but nothing major and I just let it handle the "magic", if you will. Additionally, I've gotten a new car during the time I had my issues (GTI vroom vroom) and some of the bluetooth features were wonky sometimes (It's a new car, so I wasn't sure if it was just buggy sometimes, or a result of the phone), I noticed after disabling some of the xXx tweaks, they seem to have cleared up as well (May have something to do with it aggressively clearing items in memory, not sure?) Overall, I'm much happier with the device again.
I'm gonna continue to try to pick through and see if I can find that best of both worlds middle ground, but a LOT of my drain and issues have been fixed by tweaking xXx some. Here I was thinking it was coming from an update.
Side note: I'm not hating on xXx at all, I'm still using it, but it was causing some major conflicts with some of my settings and bringing down the quality of the device. YMMV.
Interesting on both accounts (memory and BT). My wife always complains about the BT sucking when I'm in the car, so I'll have to try this. I've always just blamed it on bad manufacture BT implementation and the lack of updates.
