Hi, I've been using FRX04 for a while now, and everything's working awesomely, it's just that after a while of using the phone, the network connection just disappears and after that, the only way to get it back is by restarting Android. Usually this happens after I make or recieve a call or send a message, but not necessarily. Is there any way to fix this? I've tried to switch airplane mode on and turning it off but after I turn it on, the option just greys out and nothing happens. I'm using a GSM phone, the model is RHOD100UK, if that's relevant. Any help would be greatly appreciated
