Hi, I have the Samsung Galaxy Tab 2 7.0 and it upgraded itself to the 4.2.2 Jelly Bean not long ago. The upgrade has some has some "okay" aspects BUT there is one change that sucks. Since the upgrade, the volume on my Bluetooth speaker (iHome - iDM8) have decreased substantially. I have tried a bunch of different volume booster and equalizer apps and nothing brings it back to the previous volume levels which were great on this speaker prior to the upgrade. Has anyone else experienced this and does anyone know of a solution? And finally, if there is know solution, does anyone know how I can go back to the previous Jelly Bean? Thank you.
