It's time to scrap the Xperia division and exit mobile altogether. Sony has been given chance after chance after chance, and they fall into the same tropes every single time.
1.) Pricing their phones nonsensibly to the point where they represent bad value for money. The devices are competent, but to try and layer a premium price over the likes of Samsung, HTC, and LG just screams stupidity.
2.) Championing build quality when it doesn't exist. The Xperia Z lineup has always been water, dust, and scratch resistant. You would think a phone like that could handle a fumble or two? Wrong. Numerous issues from SHATTERED backs from tiny falls, expensive repairs, and overheating have effectively made Sony ditch the Z line and create the X.
3.) Ignoring the US market altogether and arriving so late to the party- that the luster has completely worn off. Xperia Z's when announced tended to have some sort of redeeming quality- whether it be the excellent battery life, decent camera performance, looks- whatever. However, when it comes time to launch in the US- we'd hear rumors for months that Sony was investigating going to carriers, only to find out- they'd launch on T-Mobile when the SUCCESSOR PHONES ARE RELEASED IN EUROPE.
4.) Phones launching with an achilles heel. The Best of Sony branding is quite disappointing, since the original Xperia Z had a screen with god awful viewing angles, the camera sensors are "top of the line"- yet are always three or four steps behind the competition using Sony's PREVIOUS sensors, and to top it all off- sound quality - for a company that champions "audio" - has never been a priority or something any audiophile could hang their hat on. No matter which Xperia has launched there's always a "quirk" that puts the phones into "not worth it" territory unless you are an extreme enthusiast and want to buy a phone as a conversation point since no one owns it.
Incompetence, incompetence, incompetenece. Scrap the division.
