There is a newly released Speccy-Android 1.9.9, my Sinclair ZX Spectrum emulator, on the Google Play:

This release adds the Search Files function and a new toolbar to the File Selector. You should now be able to find your Spectrum files wherever they are on your SD card, something several people complained about. I have also fixed a few crashes and the empty file list problem on devices with no "/sdcard" folder.

Added a new, nicer toolbar, fixed at the bottom of the screen.

Added File Selector "Search Files" function to search for relevant files.

Added Android menu and action items to the Gallery.

Pressing SEARCH key in File Selector now searches relevant files.

Fixed situation where some people got empty file lists in File Selector.

Fixed crash when reporting failed license check.

Fixed crash in Settings.
