Nexus 5 screen remains black after standby

[Filibertob]

Hi all,
Since 4-5 days (after the last upgrade) the screen of my nexus 5 doesn't wake up from standby remaining completely black almost any time I put the cellphone in standby and forcing me to reboot the device. The nexus is not rooted and the version is 6.0.1 build mob30p. Is anyone experiencing the same problem? Any solution?
Thanks!

Welcome to Android Central! Try booting into Safe Mode, which temporarily disables all 3rd party apps. https://support.google.com/nexus/answer/2852139?hl=en

If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.

Thank you very much! I will try! Is there a way eventually to find out which app cause it?

Unfortunately, you usually have to uninstall apps one by one, and keep checking when the problem goes away. When the problem goes away, the last app you uninstalled was probably the culprit.
