PDF Scanner - Document Scanner

I don't know what's going on. All of sudden Adobe reader won't open most of my pdf's. Only a few ones will open. App shows its updated. I opened these files many times before but now nothing. I'm on a Samsung Galaxy Note 9 and I'm a free user.

More than worthy buying over any of the expensive Main-Stream application like Adobe etc. Interface, features and its simplicity are amazing!! It has bit of a learning curve though if the person is new to such app as there is no tutorial provided. Best part about this app is it makes my photo scan look better than those cumbersome original scanners that too without even using the built-in features provided by the app. If you really want to unlock the true potential of the app than the paid version is even more better. I bought the premium version for the sake of it and ended up using it on daily basis. All my administrative work is being done by just on a click of a button. Weather it is adding your signature, changing the size of the page, changing the size of the scan etc. Everything is just perfect.
