Hi All

Good Morning.

I have faced a unexpected issue after update my Xperia Ion (Lt28h). After doing this update I am unable to use 3g Mobile Data. Seems when I try to download or update and apps from play store, my phone completely hang. even if I try to browse from Chrome or Facebook, it’s not working. 

I have tried to re-configure network settings still not working. After re-configure I have found that, if I switch network to GSM only (From Mobile network mode) mode I can do everything.

Please note, I have also replace another 3g SIM card still same issue.

For downgrade either you need to take your phone to Sony Service Centre or Flash your device...

I have already flash by myself and downgrade to ICS. everything works fine. For jelly Been its must be software bug. never expect this from Sony so sad.
