That's weird; Android works pretty well for me these days. I have lots of problems with sluggishness, freezing, rebooting, etc. on my old HTC phone which had Gingerbread (I think), an ancient version of Android. But on my Galaxy S4 and my current Galaxy S5 (which is updated to 6.0.1 I think), things work quite well. It's not perfect of course: I'm using the regular Samsung/Sprint ROM which is absolutely loaded with crapware. I disabled all the crapware, but it's still there wasting a lot of valuable space out of my 16GB. It could be a little faster at times, like with the camera. But freezing and reboots just aren't a problem the way there were on old Android versions that I've used. I do plan on trying out CyanogenMod sometime when I have some free time. But for now, the carrier-pushed version seems to work decently well. I don't have any giant complaints.
