I was getting the same problem on my S4 so I went ahead and got the S5 on Friday and it's doing the exact same thing. Sometimes under heavy use, the phone will just freeze up for like 20 seconds and I can't do anything. If I press the power button and then wake the phone again, it will bypass the lock screen and go right back to whatever frozen screen I was on. I did a factory reset on my S4 and it did nothing. I've cleared the Cache on this phone multiple times and it does nothing. I've tried different launchers, Nova and Apex and it does nothing. WTF is with this crap? I love this phone but a brand new phone freezing exactly the way my S4 did is complete crap. I've read thread after threads with tons of people having the black lock screen thing and various other problems. I'm thinking this is a Kitkat issue?
I'll take any suggestions on clearing this up but I've probably already tried them. I've gone through and done so many different things to try to prevent this and nothing works.
It's really bumming me out because I love everything about this phone but when it freezes up, it makes me want to throw it against the wall. I thought about bringing it back in since I just got in on Friday but I really don't think it's a hardware issue since I had the exact same problem on my S4. If the HTC1 M8 didn't have such a lousy camera, I'd think about switching to it.
