I'm having problems with my HTC One X. The problem was that the WiFi kept switching off whenever I was consuming data (the little WiFi symbol at the top of the screen would disappear and then reappear a second later). This meant that if I was using YouTube or sky go, the video would constantly stop playing and then restart. My phone was sent off to HTC for "repair" and its come back in a worse state. The WiFi symbol continually disappears whenever I'm using it now, meaning that the WiFi is switching off. If I try to download apps from the app store, the WiFi will cut out numerous times during the download and the percentage bar will say "waiting for network" until the WiFi symbol reappears. It's even cutting out if I'm surfing the web. This isn't a problem with my broadband at home because I have numerous other devices that all work fine on the WiFi. I've also tested my phone on a different WiFi network and have the same problem. So the issue clearly lies with my phone. Has anyone else heard of this problem and is there a way of fixing it?
