Need 70$ to fix my dead phone.

So, hello everybody. I am a 15 years old Java developer from Morocco. I am currently working on a notes/memo app called Quill. I plan to put some exceptional awesome features that no other app has ever made. My PC is kind of bad when it comes to running only Android Studio, so when I test my app I have to use a real device instead of an emulator (Cuz my HP Pavilion G6 cannot handle that). I got only one handset which is a Samsung Galaxy J5 Pro (2017). It has a known problem with its AMOLED screen which actually get blacked (black spots start expanding, either slowly or fastly until they kill the whole screen), and actually that happened to me and it broke my development process as I have nowhere to test my app. I know that there are possible ways of using the phone using a cable but it's really awkward (my app supports multi touch and I can't use that on the PC) and I have to stay tied to the PC for everything from chatting to searching for math exercices.

So my hope is that you help me reach 70$ so I can fix my screen (the screen value is 60$ and the replacing process costs between 5-10$), and if possible, I need 30$ to publish my app for external testing when it's in beta stage (a Google Play Developer account is not free, it's worth 25$).

Whoever donates more than 2$ will get a free premium (forever) in my Quill app when it's fully released. Just leave your emails (that you use for Google Play) so I can send you your gift codes.

You can find some version of the app here. There are many unuploaded updates, but I think that's enough for a proof.
