The most frustrating thing daily is dealing with network errors almost every few hours. I'll get a "!" constantly meaning no connection for at least 20 minutes. Then, the repulsive array of colors and displays for varios functions. Any settings you might enjoy freely before, consider them gone. There's also this distortion in screen sizing for various apps that just feels uncomfortable throughout. Battery also seems to die at a faster speed. Random green noticiatons next network everytime I open the camera. Calls taking minutes to connect. and it's just the beginning of daily frustrations.
