Android Device Manager Phone cant be located

[DH2706]

Good morning,

my Problem is as I wrote it in the Subject that my Sony Xperia Z1 can't be located by the Android Device Manager. I already looked up the Google Settings and the Remote Control is on, also I activated the Manager as an Administrator and GPS is turned on of course.

I can locate my girlfriends Z1 Compact and my Z but I can't locate the Z1 from any other Phone.

Thanks for answers

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.

Thanks for your answer,

I guess if there is no other way, i will have to try this, but are you sure that there is nothing else I could Do?

Do you have stamina mode on or any antivirus or taskillers?

No but I solved the problem by reinstalling Android, I guess when I upgraded to 5.0 the problem occured

Reinstalling android after a major update it's a great idea, it smooth things out.
