Anyone know what causes this error on a new Galaxy Tab A8:
void setup() {
fullScreen();
background(209);
}
void draw() {
}
Hi @svan ,
You can add a follow up on this GitHub issue:

needs confirmation
I can't run any sketch on my device, even the tutorial code. The code builds and… I can see the sketch on my homepage but it crashes on startup. This is my first time using Processing for Android. My phone is a Xiaomi Redmi Mi 9t.
Tutorial code:
```
void setup() {
fullScreen();
noStroke();
fill(0);
}
void draw() {
background(204);
if (mousePressed) {
if (mouseX < width/2) {
rect(0, 0, width/2, height); // Left
} else {
rect(width/2, 0, width/2, height); // Right
}
}
}
```
Here is the error code:
```

Edit: Just tried in my friend's phone and it worked. I don't know why my phone's not working though.

A revised AndroidMode was created by @ajavamind and posted on a github site. When downloaded and unzipped the revised AndroidMode was placed in the ‘modes’ folder of the Documents/Processing folder (previous AndroidMode was renamed to keep it from being used). Now I can continue Android development without any errors on my Galaxy A8.
