Network down issue

[PavelT]

Hi guys, 

I have a problem with my new Xperia V (lt25i). Phone loose the network and can't reconnect to it, but at the same time indicates that everething is ok, signal strength displayed as max, and internet connection also displayed. I can't make calls and use inetrnet services until i reboot it or switch off\on airplane mode. I tried different modes a netrwork mode with LTE and without - result the same. Sim is also ok - i cheked it in another phone.

And one note, usually it happens when i go undeground where network only available on the station, so the phone needs to reconnect each station.

Thx!

Have you tried with another SIM card in your phone? Despite the fact that the SIM card works in other phones it would be great if you could test with another SIM card in your phone.

Its a bug of the phone itself. I also have that bug with the phone.

Worse is I can not connect to LTE. Everytime the phone picks up a LTE connection he tries to connect and then loses signal (like u mentioned in your post)

My provider blames Sony and is trying to get new firmware for the LT25i...
