android - Normal font appears italic on some devices. Why and how to fix? -

the problem text in textview looks fine on android emulator, doesn't on actual device. not device , i'm not familiar android system, don't know if it's somehow overridden system settings.

here how looks on emulator:

and here how looks on device:

textview:

<textview     android:id="@+id/text_header"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:textappearance="@style/apptheme.text.stepperheader"     android:text="header"/> 

style:

<style name="apptheme" parent="theme.appcompat.light.darkactionbar">     <!-- no text-related settings here. --> </style>  <style name="apptheme.text">     <item name="android:textcolor">#1f1f1f</item> </style>  <style name="apptheme.text.stepperheader">     <item name="android:textsize">14sp</item> </style> 

if problem in appcompat theme parent — 1 should use instead? want consistent app on devices. can explain why it's happening , how fix it?

to able same font result on (almost) every device, use custom font. can download 1 websites dafont, etc. then, can apply custom font (and without need details of android styles) ui widgets using calligraphy library. see piece-of-cake documentation examples usage.
