Uninstall the dangerous ImeMess app from my tablet I have the ImeMess app warning keeping popping up even after I have done the unistall instructions. Where is it located? How do I permanently unistall it?
If this app is inbuilt in your phone, then there is only way to uninstall it i.e., root your phone and uninstall this app from your phone.

imeMess has been posted as Malware by Avast, I found that by using junior gates debloater I could block Fotaprovider, this stopped the adware. The malware is in two parts imeMess goes to a server and loads the adware this is stored in a folder called Juice on my device.
Been running Android 5.1 and this runaround seems to work.
