I don't like the build quality, I've never dropped it but when I shake it, it sounds like something is loose in the earpiece - the back cover has horrible bits where it was broken from the mould. With each update comes a new set of bugs, now I am totally unable to copy and paste without the phone crashing whatever application I was trying to cut/copy from. I did a factory reset which cleared the issue for a bit but it has come back again.
I prefer stock Android, I don't use the features that touchwizz adds. Another annoyance (but this is not the phone's fault), spotify can't use the SD card so I have a 32GB card doing nothing.
Another reason is I get bored easily and I want to try a Nexus 4![]()
I had the copy & paste issue, the fix is pretty simple and quick to do if you have rooted your phone.
