Hey guys, I have a problem with my Sony Xperia Go (running the newest android) It's brand new, bought it just few weeks ago. Yesterday I finally went to get myself SD Card (8gb, class 10 UHS 30mb/s Sandisk) and everything was good, but when I copied about 40mb worth of mp3 onto it , the ringtone started responding slowly when someone calls. The phone lights up and starts vibrating but the ringtone starts ringing about 5 seconds later which obviously gives me less time to answer the call. What's really strange is that even when I copied the ringtone onto the internal storage the problems remains. But when I completely remove the SD card from the device, everything works fine! Anybody has a clue? Thanks in advance!
