Thanks ....good information ..

I meant quality for ios/samsung androids.

Also, the samsung camera is better for pictures in dark area, and also requires you to be quite stable when taking the picture. Lots of motion blur otherwise.

iphone is better for pictures with bright lights/outside

Just take a look at some phone specs. Lets consider two competitors. The Samsung Galaxy S4 vs iPhone 5 or iPhone 6. Without going into much detail: The phone model is important. As far as the operating system is concerned - I'll stick to Android for the reason in my last post. Now looking at the above phones we can see that Samsung has a faster processor and 2 more cores. That alone is a win in my book. No matter how great your computer - if your processor is slow, everything is slow. It also has 1024 (1GB) more ram. Not to mention a longer battery life! However, I'll take an iPhone over ANY LG product. Quality for androids/ios are both superb though ( from my experience )

How a bout quality in performance seungli?

Android doesn't limit your ability to customize your phone like apple does. Do you need more reasons? :D
