What are you using for Size that will make the difference or it could be that you are only half pressing the camera button. And with certain camera app that it only take half sized pictures.
For default camera settings it is 5mp and usually about 1.5mb in size. Proshot the size are the same when set at 5mp.
I have my camera setup so that I can touch the screen to take my shot's.
I have a 521 how do I set it up so that I touch the screen and take shots? Also sometimes ill take pics with the default app and they come out a bit blurry any idea why?
Busy day at work and after work has well..
In case you have not found it yet. Settings->Applications->Photos+Camera->Select option Tap Screen to take Pictures and Video
Blurry pics - Check your settings a high ISO can sometimes cause blurry pics, but usually steady hand is needed if tap screen to take pic's, or hold phone very tight and use camera button. What I usually do is take pics in burst or multishot's. Then pick the best out of them.
