Low bluetooth sound since ...

Hi,

SGH-I747M 4.1.2 on Rogers.

Since the last update , I am having issues with my Bluetooth. The sound is really low. I have a Beat's Portable and before the update the sound over Bluetooth was good, now it's like having a dial to 3 and that's it. The Portable beatbox is not the problem because with my Asus Transformer tf700-t tablet I have no problem at all.

If I don't use the equalizer the sound is not that low but if I only try to get the equalizer to a +1 on bass the sound drops half ...weird. And that's with any player or equalizer program.

Hope somebody knows something to help me out.

Thanks !!
