I have had my phone for a few months and it's been working fine up until a few weeks ago when all of a sudden, it stopped allowing me to download ANY apps.?? I know a lot of people with the same phone and they have no issues. My brother's phone, using the same Wifi, has no problems either? All of my settings also seem to be the same as my brother's. I just get a blue line with no progress, no error messages...just nothing. Any help out there for me? Thank you.
