Network problem on xperia u

[WILKLIS]

Hi. I got  2 weeks ago , new unlocked xperia u .Everything works fine ,but 3G network(wi-fi works super). No metter where I am . The only thing I can do on internet is reading  text . Everything  is very slow. I am unable to listen to the radio stations, watch youtube ... I checked 3g speed on mobilespeedtest dot com which shows 4.7Mbps. What can I do to to make my phone work properly?PLEASE HELP... I love this phone...

Restart the phone often to refresh RAM memory.What browser are you using?I suggest not using battery savers,task killers as they slow down the phone and interfere with phone functions.

Hi. Thanks for your advice. Removing "task manager" has helped a little, unfortunatelly I am still unable to listen to the radio and watch vodeo on line. My phone has :Android 4.04 , it is sony xperia u  model st25i baseband version u8500-49020908-p2h_ec01 . I use  default sony browser and opera mini 7.5.3 (the same problem-no differance ) . I tried to use skype- to slow... wi-fi :perfect, 3g- poor (2 out of 10)

your network data its too slow, that's not a phone issue but a network coverage issue.

O.K., but why do I get  5417(mbps) result on mobilespeedtest-dot-com ? Why do you think that its the problem with network, not  phone?
