For a long time I used default camera application, as most people do. On all phones I used. But few months ago somebody recommended me "open camera" and I decided to give it a try. And guess what? I still use it. Moreover, now it is my default camera application now.
Actually, there is nothing so special in it. There is no super killer features. Nothing like that.Instead, there are minor things here and there. Fast access to shooting modes, fast switch between photo and video, line showing how far your camera from the proper orientation, you can switch the flash light statically etc.
Really, nothing so special. But together these nice features do the work.
PS: actually, this is already 4th application from the very base set I replaces.
Others were: contacts, messages (sms), gallery. I will write about this later on
