After writing a few posts about camera problems I must say gaming is beautiful here. Playing Dead Trigger 2 on ultra high and brigth-ridge with all settings at maximum is fluent, no lags, and almost no excessive heat. Awaiting a camera fix eagerly,esp to improve responsiveness and the ultra slow portrait mode.
Just watched the video. I think Arun had a faulty Exynos unit. Like so many of us probably have. My 1st unit was just terrible in terms of overheating but this 2nd one is excellent. I repeated the same test as he had peformed. Ran Antutu 4 times in a row with no noticable decline in performance and cpu temp remained around 40c. See screenshots. I tried to contact him on Twitter to ask him to repeat the test with another Exynos unit.
