Okay this is probably a newb question but I can't find any solutions on google.

I'm a new android programmer and I made a simple hello world type program. I didn't do any funny configurations in the layout xml file but for some reason on certain devices the screen looks really zoomed in and almost kinda pixelated.

Is there some kind of common reason for this? All I have on my linear layout is an EditText widget, a textview widget, and two button widgets.

My Layout:

```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="10px"
    >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    >

<EditText
      android:id="@+id/txtUser"
      android:layout_height="wrap_content"
      android:layout_width="200px"
      android:text="" />

<Button
      android:layout_height="wrap_content"
      android:layout_width="wrap_content"
      android:text="Submit"
      android:onClick="userSubmit" />

</LinearLayout>

<Button
      android:layout_height="wrap_content"
      android:layout_width="wrap_content"
      android:text="Clear Screen"
      android:onClick="clearScreen" />

<TextView
    android:id="@+id/txtMain"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textSize="16px"
    android:text="Ready\n\n"
    />
</LinearLayout>

```
