Pass PC patch app on mobile

Hello!

Let's see if someone with more notions of computer science that can help me ... I have created the patch of LibreLink and I have it on the computer, but there is no way to get it to the mobile.I have tried through Dropbox, but the phone (Samsung) tells me that you can't open that file format.I have also tried to install app's that supposedly serve to open APK files, but nothing, I can't, nor copying it directly from one side to the other through USB cable.

Any idea how can I do it?I also have the permits well to install external app's ... I don't know what may be failing, and I have been with this all afternoon, I can't anymore !!!Any help will be welcome!
Thank you,
Marten

Have you deactivated Play Protect?

Hello Carlos!Yes, I had the right permits to install unknown apps ... The truth is that I don't know what the file was installed but I didn't let me open.In the end I don't know why, he let me copy it through Airdroid and so I could install the patch on my mobile.Thank you!!
