Premium pricing proved to be profitable for Sony's mobile division especially with the fierce competition in the market. I hope they would at least extend software support to support the inflated price as other companies are offering 4-5 years of updates at this point.
They aren't really very special phones. Pretty average tbh with a below average flash light (it's basically useless) and terrible fingerprint reader. I only got an xperia because it doesn't have a punch-hole or notch.
Not sure why you're being down voted tbh. I had a chance to fiddle around with the 1 IV when Sony sent me the wrong phone by mistake with my online store order.
I have no idea why they are priced as high as they are either. I was not impressed by it at all.
