This phone has good hardware on paper but it seems read/Write on storage is very slow and may be cause of all the heating up.

Anyone can verify this and provide a solution?

Tested with A1 SD Bench, much better speeds than my dad's m8.

I'm getting slow speeds as well. I'm using Sandisk Extreme Plus SDXC 64GB card (SDSDQX-064G-U46A).

PC test using CrystalDisk:
Seq. Read - 85MB/s
Seq. Write - 61MB/s

Xperia Z2 using AndroBench:
Seq. Read - 45MB/s
Seq. Write - 14MB/s

If the overheating issues are caused by these slow R/W speeds,can this be fixed by a SW update or is it a hardware issue ?

Crazy - Good Hardware but lousy internal storage management.

I found out when I was trying to delete some old sms and it took forever.

The phone also heat up in the process and basically does not respond for some time (temp hang).

Did a defrag and clean and ran test but results did not make much difference.

Will wait and see if anyone comes up with a solution.

There was also an incident when the phone prompted Cache Reached when I was running the test using A1 SD Bench that Feis mentioned. Not sure if its another indication of issues.

This is very odd, either the benchmark is at fault (cannot see how) or our Z2 has been crippled - the SD card is performing almost at same level as internal storage and that should not be possible, and the random read/writes are off the bottom end of the scale!! Is it possible because we have 3gb RAM that its far slower than the competition RAM speed?

Im no expert in these things, but app said its no biggie and maybe caused by having big amount of free ram, which seems logical having 3gb total
