Weird. I've only been a smartphone user for a little over a year now so I'm not an expert by any definition of the word but as this situation goes, I've been really pursuing the answer. Before JB, I could leave both data and wifi on and it would just switch between the two depending on my location. Now this little annoyance has come up where I have to manually turn the data off while I'm at home so my wifi will work at normal speeds. And just to test it, I just turned both off (I'm at home now) and then called my land line (it rang). I then sent a test text to myself and it sent and received within a second. No data (3G/4G) or wifi connection. Turned both back on, the wifi icon goes from dim (off) to bright white (on but no Google Connection), to blue (on and connected to Google Services) and the 4G icon is there but stays dim (off). I go into the Google Play store and all the text is there but no icons. Check 'My Apps' and again, text but no icons. Within 10 seconds or so 1 or 2 icons appear and if I scroll down, more slowly load. I pull down my notification bar and press the mobile data button (the 4G icon goes away). I quickly go back to the Play Store and all the icons load immediately. Not a deal breaker but a hassle nevertheless.
I'd like to have the OP chime in here and see if he's experiencing the same deal. How 'bout it Rich, you got a copy on me here?
