Hi. I had bad experiences with Android phones in the past 18 months as mine got water damaged hence I'm looking for something that can withstand more than a drop in the sink/bath or light rain Like the Xperias. But I want to know any significant upgrades of the Z3+ to the normal Z3? Is it true that the Z3+ performance is slower, heats up slightly and has a muffled speakers than the Z3? (Reviews and videos I have seen so far indicates so). Comments please.
