Hey guys, when I go to install an apk file, the "install" button cannot be pressed, but the "cancel" button can. I have used this method several times in the past and it has worked. I recently upgraded to Sense 6 on AT&T. My phone is completely stock (no rooting or unlocking). And yes my unknown sources button is checked. Hope this is a quick fix :/ I read somewhere else that "JuiceDefender" was causing that issue a while back but I use AVG and CM antivirus. So what could be the issue?
Thanks in advance!
