I downloaded the adobe Acrobat app from the play store to fill out an employment application. I didn't open the app initially. Later I tried to download an online PDF and adobe kicked on without being opened or given any permissions. I wasn't able to move the PDF to a cloud based drive either that a normally use. My screen functions were disabled(no touchscreen buttons worked) and only my hard buttons(device specific) worked. When I opened up my phone a few moments later I had access to my screen buttons ONLY if I didn't use adobe. I uninstalled the app, downloaded the PDF again with no hassles. I have used adobe Acrobat apps in the past with some issues on other devices. Nothing like this. Any ideas for the problem?
