LTE (4G) problem

[zoran81]

Hi there,

After upgrading to Lollipop I experienced some problems with 4G.
When I'm switching from WiFi network to my carriers data network, and when the phone is set to prefer 4G the phone it often can't find data network, but when the phone is set to prefer 3G it find network as soon as it lose WiFi and if I than change to prefer 4G it imediatelly change from 3G to 4G.

I'm on Croatians T-Mobile network.
Sorry for my bad english.

I've been having the same problem since my Xperia Z3 Compact received the Over-the-Air update to Lollipop. I have T-Mobile too, and they had me re-enter the APN settings, to no avail. The problem persists. I will not do a Repair because I don't want a factory reset (for various obvious reasons). Plus, reading this thread tells me that a Repair won't fix the problem. Even through the two of us both have T-Mobile, I think this is a coincidence and this problem has nothing to do with the carrier.  This is purely a bug in the Sony edition of the Lollipop O/S.
