my new nexus 5 works perfectly except for the sleep mode, either when pressing the power button or when using daydream when the phone is charging. In both cases, the phone switches off and reboots afterwards, but not always though, sometimes I have to do it manually by pressing the power button for like 10 seconds - really long time.
I have uploaded the latest android version and I do not have tons of apps installed. I also did a complete reboot of the phone by pushing the power button and the volume down button and following the instructions.
Does anyone knows how to fix this?
