Can someone tell why my icons (left photo) are not like on the right photo?
Do I have to install something or update?
If there is a tutorial how 2 change this, pls Link 
The picture at the top? It’s a different Firmware version. There is no tutorial - it’s not something a regular user can change
@Pablo_Eleven_Pablo11 It is,after a while searching for how to do it, I finally got the new Firmware manually installed on my X5.
If someone need it, i could do a step-by-step tutorial
@FutuReality there are step by step tutorials here in the community and here http://roundandroidwatches.proboards.com/
Trouble is - no one bothers to look for them 
@Pablo_Eleven_Pablo11 after I installed the new Firmware, my batterylife shrank from like two days to not even one. Do u know why this could be so? And is there a way to increase the battery life
@FutuReality
you can install an older firmware but my recommendation would be to factory reset the watch from watch settings - always do this after flashing new FW - and monitor again for a couple of days.
