view story

http://forums.androidcentral.com – I've had wifi issues since I purchased my htc one x for AT&T in may. I have had the hone replaced and the issue was never resolved and I'm kid of fed up with it for the fact that everyone I know who has an android device other then a one x don't have these issues. Issue seems to be Interment but happens a lot actually all the time. Basically my issue is I have wifi turned on sometimes I lose connection.i notice this due to delayed alerts at times and when I'm using the phone such as on the play store, Facebook or any app that uses the I telnet every once in a while ill get a connection (HowTos)
