[Moto X Q&A] balleron24z:
Disclaimer: I've searched the forums day after day and have found nothing that helps me in any way.

Hey guys, I'll get right down to this:

I've got a Moto X VZW MM 32GB, initially shipped with 4.2.2 and running 4.4 as soon as I got it activated.

Everything on the Moto X works great, fluid graphics, fast app opening, battery (for the most part). But I've got a bone to pick with bluetooth, as well as Android OS.

First off, the bluetooth bugs, or what I'd like to call, The Blues.

Problems

- I have Pioneer Premier FH-P800BT, running great for the past 6 months or so. I originally had a Galaxy Nexus from VZW, with CM10.2 on it and bluetooth worked flawlessly, save for an obvious quality issue with phone calls/echo cancellation. A2DP and HSP/HFP would connect immediately as soon as the car came on. With my Moto X, HFP/HSP connects fine on powerup of the radio, but A2DP will not, and my phone shows "Connecting..." in bluetooth settings. When I first pair the phone (or re-pair), all profiles connect and audio works without a hitch. But every time after, it doesn't work that way. I can get around the issue by putting my radio in pair mode and turning on bluetooth, which essentially re-pairs the devices together, and that works. I think the biggest thing is that my radio connects HSP/HFP first, and then A2DP, and the phone is expecting both at the same time, and this causes the glitch I'm having. I haven't FR'd yet because this could be something that a FR won't fix (aka software issue that wasn't fixed by Moto).

- On all bluetooth devices with A2DP, sometimes the quality is great, sometimes it does what I like to call a "stucho" aka a stutter/echo. The best way I can explain it is if you've ever heard a record skip back and keep playing the same part, multiply that by like 100x. Or better example, for you Galaxy Nexus users (other phones too, if they do it) when your phone would freeze from being overloaded, and it ultimately crashed (non responsive to anything, screen won't come on, or maybe stuck on) and the audio get's hung. The sound does that on the Moto X, but it continues playing the track without pausing/skipping. It's extremely annoying, and mostly occurs when surfaceflinger is active (I'd assume that's what it is), as it's when anything animation-wise caused by user input occurs. I've also had the audio deteriorate in the same manner, but after it does the weird stucho effect, the audio slows down a bit, noticeable, like, listening to "We Found Love" by Rihanna sounded like a man singing it, and then it will speed up and go too fast after about a minute, and then resume normal playback. Despite completely pausing on my Galaxy Nexus, that phone never did have the audio issues this Moto X does, and it occurs on every A2DP device I've tried (BMW iDrive, Hyundai Sonata factory radio, Philips SBT series, my Pioneer headunit).

Second issue I'm having: Android OS

- I've tried ART and running Dalvik as the runtime, and on both, after weeks of running them, I notice that throughout the day, 3-4% battery drain per hour, with nothing in recent apps, wifi on, and all VZW software except for backup assistant disabled. I'm not complaining because I tend to make it to the end of the day with 2 1/2 hours SOT and and about 10% left on battery, but I'm curious as to why it's not making it any further. I don't have much installed. Dropbox, Facebook, Exchange account, Wallet, and other programs that don't run in the background (OS Monitor, Dots (game), etc). While my SOT can show 2 1/2 hours, it's only taking like 35% of the battery while Android OS shows like 20% or more, and shows CPU time around 1:45 hrs.

Any insight on either of these issues would be appreciated. I love the phone, everything else is perfect, but these 2 things are kinda irking me because I know this isn't the way the phone should be operating, moreso with the bluetooth bug.
