Some in-depth information on the inner workings of the phone would have been interesting, too, rather than just the pictures. Battery life is also an inssue for me, as my battery seems to have died after just 4 months. I often get error messages such as the phone apparently thinking it is connected to a computer via the data cable & trying to run Kies when it is only plugged in to the charging cable, and saying that Kies cannot run while other apps rae running, even though none are shown in the Task Manager, or I get the deep discharge.
warning symbol towards the end of (or after) charging, and sometimes I can't switch the phone off - it automatically switches on again (i.e. reboots) about 10 seconds after shutting down, even when the battery is empty, forcing me to remove the battery until I can charge it again, if I'm on the road when it becomes necessary. VERY annoying!!!

A link to the article "Samsung Galaxy S II (Sprint Epic 4G Touch) Teardown: Samsung Exynos processor and no NFC." would have been nice, too!
