lgexalter1 HAHA, I don't even know what that means. TCL doesn't use com.tcl very often. All the com.android apps were signed differently per phone. TCL uses package name of one or two apps com.tcl, one of those is camera. So I took the camera app from a TCL smartphone to see if it would install (not b/c I thought it would be a better camera app), and it didn't have the signatures issue, but it had the NO_MATCHING_ABIS issue.
