content: Opens PDF files just fine. Corrupts any files that are being saved. After filling out a form and trying to print it which is automatically saved results in a corrupted file that cannot be opened by a cell phone or a PC. This has happening for a while. I have quite a few corrupted files on my phone now. Every one of them was caused by Acrobat Reader. Update I cleared the cache and uninstalled the application. After reinstallation it is working fine again.
