My Xperia has 2 problems:
1. After 12-24 hours of working Xperia loses cellular network. Phone indicators shows that both SIM cards are active and the signal is good. But Xperia does not recive any calls! I checked my SIM cards in the other phones and they worked perfectly. I have changed SIM cards from their places SIM1->SIM2 and back but it did not help. Only switching phone off/on I may resolve the issue.
2. Battery does not charge if it capacity decreased to 20% or less. I connect the charger to the USB connector and Phone indikator shows that the battery start to charge. But battery capacity are not increasing! Therefore to solve the problem I need to switch off the phone, put off the battery, put it back and switch Xperia on. After this procedure the phone starts charging.
Our local SONY service did not help me. I had brought them my Xperia twice, but the Sony Service in Moscow did not find any problem! All answers were: "Issues did not aproved. Software was changed".
I`d like to recieve any recomendation how to repair my Xperia E Dual.
