Switching off my HTC one M8
Some help and advice please.
I've just bought this great bit of kit and find the the double tap wake up function really useful. However, the manual says that you can use the same method to put the phone to sleep, rather than using the power button, but this doesn't work, or seem to work on my phone. I have a glass screen protector on my phone - could this be the issue? I have also read that the M8 doesn't actually have this facility, so is the manual incorrect?
Any help would be appreciated.
On a different note, can anyone advise me on a 'find my phone' app - my last phone was a Galaxy S3 and Samsung had their own app.
