Hi all, I got this phone a few weeks ago and overall it is very nice phone. But I started noticing an issue with the ear speaker (the top speaker) for the last 3-4 days. I think after about a day of use the ear speaker stops working completely! So when I answer a phone call I cannot hear the other person unless I turn on speaker mode. I cannot hear stereo sound for multimedia such as videos or music and only the bottom speaker works. This gets fixed after I restart the phone. So it sounds like a stupid software issue of some kind! Why is this happening? Has anyone else experienced this issue? How do I fix this?
