It's not a problem for people who are knowledgeable when it pertains to phones. What about the other 99% of android users? My ex got malware that charged us $49 a month on our phone bill on her old android phone. This was from downloading a recipes app which she only once launched and never signed up for anything from the play store.
I have no trouble finding things wrong with Android. It's a buggy, ill-optimized system that still suffers from lag, malware, inconsistency and fragmentation. I was a hardcore android user from the g1 and still own a nexus 4 (had an HTC One a few weeks ago, got rid of it though it was likely the smoothest behind the nexus 4. I just don't like HTC build quality) and I'll always give every OS a fair chance but until I feel I can rely on an android phone and until the user experience is at least okay, I stand by my position. I was sorely disappointed when both of my top-end android phones couldn't play some of the games I wanted.
