I have updated Speccy-Android, my Sinclair ZX Spectrum emulator, to version 1.9.11:

In this version, I have finally fixed the problem with video going black when Android 2.x is rotated. Also added the ability to show the Android status bar, support for analog joysticks, and separate virtual buttons for frequently used SPACE and ENTER keys.

• Finally fixed accelerated video when Android 2.x device rotated!
  
• Added SPACE and ENTER buttons to the virtual joystick controls.
  
• Added support for analog controls found on generic Bluetooth gamepads.
  
• Now also showing status bar when action bar enabled.
  
• Flick finger down to show status bar, even if you have no action bar.
  
• Merged Freeze and Restore into single Freeze/Restore dialog.
  
• Added State Exchange access to the Freeze/Restore dialog.
  
• Collapsed all advanced menu items into single Advanced submenu.
  
• Made NetPlay a single checkable menu item.
  
• Fixed "Other Apps" link in the "What´s New" dialog.
