App has caused my phone to be unusable for 2 hours so far.... Estimated time without my phone 10 hours. Reason: cam scanner app is showing message " preparing data (17%), please do not close this app or switch to another app" 17% after 2hours really..... I use cam scanner app for work every day, if an update is this large it must have delay option I had no option to delay this update, it started as soon as I clicked on app. It's unacceptable to make my work phone unusable for the entire day!
