Screen switches off when lying on my back reading?

[AC Question]

Ok I have no idea why but upon waking up this morning My HTC One has started behaving differently. I have a couple of newspaper apps and when I lay on my back to read them from underneath the phone screen turns off.

Ultimate rotation Control will not enable and I tried un-installing it, trying it again, then re-installing it and the problem is not fixed.

Any app or screen when viewed whilst lying on my back (Screen facing down..) causes the phone screen to switch off.

Frustrated. Cannot find a setting to get it to behave normally. Can anyone help please?

I think it's a HTC One M7.. Software shows as Android 5.0.2, HTC sense Version 6.0
