Xperia Z3 Compact stamina mode problem

[blaaaaaaaaaaaaa]

Hello!

After last weeks upgrade to the latest version I cannot activate the Stamina mode in my phone anymore. 

Or rather, I can activate it, but it immediately deactivates by itself.

Any solutions to this? Has it happened to anyone else?

reinstall lollipop, that might solve the issue.

Before you reinstall, try the following: first disable stamina, then go to settings-apps-all,scroll down to stamina app. Tap on it, force stop and clear data. Restart.
