Yes, and I posted in the Client Eye thread in the Spamming section. It's failed me on both HTC M8 and HTC U10. I believe it's due to the proprietary HTC UI, which Client Eye tries to draw over the top of. I tried turning off various HTC inbuilt functions, but haven't found a fix yet (and neither has the developer)
It's a shame cos I love HTC phones (despite the crap battery life.) I've installed ClientEye successfully on my personal phone, which is a OnePlus, but I need a work phone that does wifi calling, and I've tried Nokia and it was shit. Samsubg I hate the build quality.
