Why is my Android application crashing on Samsung Galaxy Note 9?

So , I was developing an Android application for Arduino and I was right about to post it on Google Play but first I though I should test it on different devices. So I sent my apk to a few of my friends.

Here are the devices i tested it :

1. One plus 6T : works perfectly
2. Asus zenfone 5z : again works perfectly
3. Samsung galaxy note 9 : when the app is opened it instantly crashes

Has anybody ever encountered such thing ?

My first guess was about the resolution of the device: the first two devices are running at a resolution of about 2280x1080 while the Note 9 runs at 2960x1440.I added into the Android Manifest file the lines for supporting screens but seems that they don't help.

I also created "Landscape variations" and "tablet variation" for my first three activities but that also didn't helped.

Here is my Manifest code :
