Samsung Galaxy S2 (GT-i9100) – Shortcuts & Tips

Tips and stuff you won’t find in the manual, collected from the xda-developers forum, personal experimentation and other sources. Please use only tips you understand – if you don’t know what a factory reset means, you do not want to find out :)

Explanation

• “Pinch” means using 2 fingers to zoom in our out (Google this if you don’t know the word :)
• The buttons are depicted here:

  - Use two fingers to scroll until fingers are released.
  - Use three fingers to scroll fast until top/bottom.
• Phone wake up: Via home or power.

Home screen

• Multiple home screens: Touch the dots to switch directly to a screen or hold and drag left/right to scroll very fast.
• Changing shortcuts at the bottom: Click „Applications“ (bottom right), then menu, click „Edit“: Now change the three (left) icons via drag & drop. Afterwards click menu and choose „Save..“.
