To be fair, plenty of people have problems with whatever Android phone they happen to be using. It happens on both sides.
For me, my iPad Mini and iPhone 5s/6+ have been problem free as has every iPhone I've owned since the original in 2007.
I have owned 4 Android phones and one Android tablet. The problem Android phone was the Nexus 4 and the tablet was the Nexus 7. Both of those had problems with the Lollipop upgrades and the Nexus 7 has become unusable. I'm waiting for 5.1.1 to hopefully fix that.
Neither platform is perfect.
