got a Z1C a week ago. I never get 4G/LTE signal. My carrier is ok, cause if i put my sim in a LG G2 i get 4G/LTE.
From Network settings menu, if Iset network type to LTE/WCDMA/GSM, after a while it catches 3G/H/H+. Going back in the menu, the network type falls back to WCDMA/GSM.
From *#*#4636#*#* menu, if I set mode to LTE-only, I don't even get signal.
Is updated to last version (android & apps)

is your Z1 compact compatible with your network's LTE bands? do you have the correct APN settings? are you using a nano SIM card?

Thanks for your answer.
1) carrier band is 7 (2600MHz) only atm. Should be OK
2) APN settings : tested APN settings sent at first start from carrier and ones downloaded from sony by network menu. Difference is minimal (sony adds a-gps and dial up flags but carrier replaces hostname on mms apn by IP). Both allows me to 2G/3G/H/H+ and send receive mms
3) Sim card is an old (4years) 2 format sim. micro and normal with adaptator.
Regarding APN settings, do you have some particular settings for LTE ? I saw the LTE flag in Network APN setting.

This is exactly my problem mine seems unable to lock on to weak signal it has been sent back 3 time but all they say is it is within spec ,Which i agree but only if you are in a full signal are
Mine has only started since updated to lollipop
So it seems to me that the 4 g signal has been used and the 3 g lowered
My post is weak "network signal "

Since yesterday its fixed. Don't ask me how... Staying to lte prefered and getting lte. Last thing i did was forcing carrier network to lte after a manual search.
Uliwooly: you were right. Got only 3 db difference.
