Hi,
I am mainly interested in S4 Active because the LCD screen should be better than S4 for viewing ourdoors, especially in direct sunlight.
True, agreed
But how much better is it? Or phrased differently, how bad is S4 really outside?
individual preferences. I like the fact that it had hard button instead of soft key for "back. Secondly, I find S4 Active more snappier than S4. U can check out hardwarezone review, the reviewer also had the same sentiment.
Also, is S4 better than S3 outside? (I ask because I know somebody with S3, so I could try it out). In terms of specs, definitely.
BTW, I also like the physical buttons. But the camera is better on S4, and Active lacks temperature and humidity sensors which could be useful sometimes. There's no perfect thing in this world, u gain some, u lost some. 8mp is also sufficient enough for everyday point and shoot. If u really need a good quality camera phone, u should be looking at Nokia 808 or the upcoming Lumia 1000 series. For the Temperature and Humidity Sensor, frankly, I never even use once when I was using the S4. So, it's actually not a loss to me.
It's really really hard to choose ;-)
