Okay so here is how it goes. My brother has a Samsung Galaxy j7 and it has some really catchy versions of the normal Android apps like, clock and calculator are very different and good looking though. Now whenever I try to install them in my phone they just crash ( I sent their apks through share-it ) and they don't work. I just want to ask is there a way I could install them in my phone, maybe edit the check point or copy the code or something else. Am using an Htc, if that helps. I really don't have any programming experience in Android or Java.
