Anyone still having connection problems? I got the first update, then the second. I'm sitting in my office in downtown NYC, where there is a CONSTANT 4G signal. However to date, my phone will only hold a 4G connection for 5 minutes at a time before losing ALL connectivity (sometimes it will show the 3G icon - however it will not connect to the internet at all when it shows this). The only way I can fix this is to turn on airplane mode, then off again. It will usually reconnect to 4G after a minute or two after doing this. Otherwise, it usually just doesn't reconnect to 4G (or any connection to the internet whatsoever) on its own. But seriously? Youtube = useless, Web browsing = only available about 25% of the time that I want to use it, the list goes on. Has anyone found a way to SOLVE this? Is rooting the answer? What must be done? New radio? Please be detailed if you have success with your connection. Thanks!
