LTE (4G) problem

zoran81 — Fri, 24 Apr 2015 18:12:22 GMT

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.

Double check the APN settings, also contact you Tmobile regarding 4G coverage.

I've checked APN setting and the APN protocol is set to IPv4 and my area is covered with 4G signal.

My coworker also has Z2 on lollipop, APN settings are same as mine but he has no problem. His phone imediatelly change from WiFi to 4G or H+ if there is no 4G while mine don't.

It'll be wise to get a brand new SIM card

also do you have stamina mode on?

Any antivirus? or taskillers?

No, stamina mode is always off.

Antivirus only AVG which come preinstaled with phone, no task killers.

Well, last night I do the factory reset, but problem is not solved.
Sometimes phone finds 4G really quick, but when it can't find 4G it don't find 3G or H+, and that bothers me a lot.

Get a brand new MICRO SIM card and double check with your carrier network for any 4G LTE coverage issues.
