Adjust picture quality Cut down on file size ANDROID TIPS
By default, most cameras will shoot at the highest resolution provided, but this does have an adverse effect on file size.
For example, an 8-megapixel shot may be 700K or bigger, so you don’t want to send too many such files if the receiver has a capped data limit. Also, sometimes you may not want a large image if you are simply using it for, say, an avatar. Thankfully you can reduce the file size from within the Camera app’s interface. So before taking the shot, press the circle icon (with the A inside) and then tap the small settings icon. From here, tap the centre icon and you will then be able to select different resolutions (from 8MP to as low as VGA, which is quite small).
