I picked up the Xperia Z2 Tablet about a week after I got the Z3v for that $299 tablet deal. I love the tablet; it's fast and works great. But, I noticed that sometimes when playing music (the included loaded songs) it would sometimes lower the volume on it's own until I could barely hear it. Re-orienting the tablet (so it auto rotates) would immediately fix it, and the volume would return to it's original setting (for 10-20 secs) until you rotated the tablet again. I also tried this with youtube videos, my own loaded videos of concerts I took, and iHeart radio streaming music. All will display this behavior. I checked all the sound and volume settings, even hard reset the tablet erasing everything. I then took the tablet back to my Verizon Wireless Store and they exchanged it. The new one does the exact same thing...it's 99 percent of the time, and there is a slim chance that every so often it does not do this, but it's extremely annoying. I searched online and cannot find any similar issue. Anyone observe this behavior? I took it back too the Verizon store again, but it actually stopped doing it there, but when I got home after about 15 minutes of playing some streaming iHeart, it does it again.
Looking for an answer.
