Bro, I think..i replied you..right now, there is no official way to use this app in M series..but you can definitely gonna find some apk files on Google.. There is another similar app called NiceLock app..if you are ok with the 3rd party apps, you may try it..
Bro, just relax..there is nothing special about GoodLock and all..yeah it helps in customization of your device homecreen and notifications..you can achieve that by using some paid/free launchers. If GoodLock app is not available, obviously you can't do anything..so just forget it and njoi what you have.. 😌
