Can anyone help me? I love this phone, or I WANT to love this phone fully, but the fact that it has no proximity sensor is just becoming too much. I hang up on people almost every call I make!!! Either that or I somehow start a 3 way call, or put the other caller on hold while I accidentally dial a random # from my contacts. It's affecting me enough that I'm seriously thinking of bringing this phone back and exchanging it for the moment. I don't want to, I have all my apps and stuff set up, but this phone isn't worth it for me if it hangs up on all of my calls. I have kids, I'm often having to put the phone against my shoulder to use 2 hands while I talk. I need something to lock the screen! I tried call caddy, but it didn't work right at all. I was still able to end the call and dial while that was enabled. Is there any other kind of app out there? Third party? I'm desperate because I only have like 20 more days to exchange the phone if I can't find a solution.
