ICS(Android 4.0) users:
Please don't enable the ICS option "Force GPU rendering", lots of apps will not work, include my app! Google, don't you test the new features before release them?!

HTC users:
Open a photo from SMS will fail because HTC want a gallery app with "SMS reading permission", but I think it is not logical!

 There are hundreds of phones/tablets in Android, I am always doing my best to make my app working fine on every device! So, if you find any issue, before you post useless comments or rating, please try to send email to me, I will help you to fix it!
