Hello fellow Xperians...I'm from Hyderabad.I have received the JB 4.3 update on 7th May..I tried to download it through mobile network..It went smoothly upto 65% and then the downloading disappeared..It was back to notification(New system update available)...So I decided not to waste any more mobile data and update it through wifi..Today morning,the notification is gone..Did anyone face this issue??

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Strange, have you tried to open the update center application to search for new software update? 

If that says you already have the latest software, try to update using a PC:

Yeah,I tried after doing a factory reset.Got update for update centre,but no JB update..Pc companion says My phone has the latest software update..I tried Sony Update Service too..But no result..I heard that the update for Xperia M is only available through OTA..Is that true?
