I installed PDF AI text reader about a month ago and it will not let me remove it I habe tried every way possible and I cannot clear it from my phone. Since installing it my phone is acting strangely and I'd like to know how to remove it please!
Hope you are doing well. Per the description, you cannot uninstall an application.
Are you referring to Acrobat Reader Mobile? If yes, you can go to Settings (device's settings)-> Apps-> look for Acrobat-> Click on uninstall on the bottom left.
Hope this helps.
