[Xperia Z General] Tsais:
Common problem on Z series, not fixed for 3 generations now...

This is a common problem on the entire Z series of phones:

The camera gets the processor extremely hot, which cooks the waterproof glue used to attach the back panel.

To make matters worse, Sony squeezed an NFC chip under the back panel, exerting outward pressure on it. Once its come loose over more area besides just one corner, it will stick out so far, it produces a 3 millimeter gap, and when you push it back down around the edges, the panel will actually show curvature and pop right back out.

That's poor engineering and it has put me off from buying another Sony phone, especially since the problem has remained the same over 3 generations. Not fixing this is either careless or intentional.

In addition, there's no international warranty, so don't travel with it, or you'll end up like me: My phone's back popped off along one side and soon after, it went into an infinite boot loop. Unlike Samsung, Sony does not offer any way to get into safe mode or recovery mode by pressing a button combination on the phone. No, you need to connect to Sony's PC Companion software, which will not recognize your phone if it never finishes booting. So while you could easily fix a bad app, virus or OS corruption issue on a Samsung phone, on a Sony phone you're up sh*t creek and have to bring it in.

Now, after telling me the warranty doesn't cover the phone in the country I was traveling in, they also told me they couldn't even help me for cold hard cash, as most smaller Sony service centers are not allowed to repair the waterproof line of phones.

I just got through ordering a replacement phone from Amazon, since traveling without a phone to book things in advance becomes very expensive.

The enormous heating cooks the glue, while the poorly placed NFC chip exerts outward pressure.

Bless my frumpy old Galaxy S2, which has withstood my time with it without a sign of wear, followed by taking the abuse of my now 5 year old daughter for 3 years.

The right kind of Polycarbonate is an awesome material to build phones with and Samsung makes them Rock solid. I guess that too maybe at an end with the A series and the S6...

Your suggestion to test the phone in water on the day you buy it is good.

The rest of your suggestions are at best an insult to users. How come I can record a 3 hour drive with a Samsung S5 in 1080p and it merely gets a little warm, while the Sony Z2 drops out of video (also 1080p not 4k) mode after 20 minutes with a message that the camera was shut off to prevent overheating.

Why can't the retarded thing control its heat in a metal casing? Ahh, because there's only slivers of metal stuck to the outside of a plastic case. "Metal and Glass Case" is just marketing bs. And if it does shut off the camera to "prevent" overheating, why does it still cook the glue anyway? I've never needed a CPU temperature meter on any phone and the Sony isn't any higher performance than Samsung's competing models.

I admit, I bought the Sony for the looks. A mistake I've wasted $500 on. Apparently, you can have either pretty or sufficient heat dispersion, but not both. Reminds me of some crap cars with great looks.

Apparently, all of Sony's engineers were sold along with the PC division.

(unless they're designing these crappers to break on purpose)
