Camera performance of GS4
Russian tech site posted GS4 camera review in comparison with HTC One, iPhone 5 and GS3. Though it's all written in Russian, Google translator will let you get a glimpse of what GS4 camera can do. At least, you don't need to understand Russian to see the images taken by the mentioned smartphones.
It seems that Samsung made huge improvement overall. Especially Samsung seems to succeed in suppressing noise significantly even in low light condition. (Personally I thought of buying Note II recently but I changed my mind and look forward to the release of GS4. I think I can't wait till they release Note III later this year.)
Looks like the performance from the combination of lens, image sensor, processing module and firmware/software of smartphone finally on par with the point-and-shoot camera level. What do you think?
