BQ 4.5 Ubuntu Touch no GPS Signal

Hello! My Ubuntu Phone doesn't find my position. I've got a SIM card inside and use WIFI too. I try other apps which use GPS signal and they all fail. First put on of the phone 14.4.2015

Software

QS Build no. 20

My phone tell me that the last update was on 14.03.2015 but I updated everything after first turn on (yesterday)

I hope I gave all required information. I recognize that the system sometimes has some problems so that actual app be closed.
On Google+ I have a discussion where other users describe same problem with there Ubuntu Phone.
Thank you for your help

Hello again! For my phone I solved the problem. I has a Sim card in my phone but the provider didn't fill in the internet settings automatic. So I haven't got mobile data. I recognised that, after I left the first time my WIFI zone and try to send a message over Telegram. After I filled in the required data everything is fine.
