Master Browse

A utilitarian, tile-based folder-hierarchy media browser for Android tablets (built for the Samsung Galaxy Tab S11 Ultra). Dark, minimal, no animations.

Features Tile grid browser — folders first, then images/videos, with fast thumbnails (Coil, sized to the tile, memory-cached; video tiles show a frame from 1s in).

Sees everything — uses direct filesystem access ("All files access"), so hidden folders, dotfiles, and folders containing .nomedia all show up. MediaStore is never used.

Home folder — MENU → Set this folder as home (or long-press a folder tile). The app opens there on launch; HOME jumps back.

Custom folder thumbnails — long-press a folder tile → Pick thumbnail for this folder, then tap any media inside it. Or long-press a media tile → Set as thumbnail for this folder. Falls back to the first media file found inside (one subfolder level deep).

Fullscreen viewer — tap a tile. Videos autoplay, loop forever, and have a live-scrubbing seekbar + play/pause. Tap the screen to show/hide the controls.

Swipe navigation — swipe left/right (when not zoomed in) to go to the next/previous item; the item follows your finger and snaps like a pager. Double-tap the left/right half of the screen to jump previous/next instantly.

Keyboard — with a hardware keyboard, ←/→ go to the previous/next item, and (on videos) hold J to rewind or K to fast-forward, accelerating the longer you hold.

Zoom — pinch to zoom images and videos, drag to pan when zoomed. The 1:1 / FIT button toggles between fit-to-screen and pixel-perfect (1 media pixel = 1 screen pixel).

Split view — the SPLIT button moves the current item to the left half and opens a tile picker on the right half to choose a second item. Each pane has independent zoom, seek, and swipe navigation. PICK re-opens the picker for that pane; SINGLE (or back) returns to one pane.

Storage toggle — the SD/INT button next to MENU jumps between internal storage and the SD card.

Pinch tile size — pinch anywhere on the tile grid to grow/shrink the tiles; the size is remembered.

Trash — long-press any folder or media tile → Delete (with confirmation). Items move to a .MasterBrowseTrash folder at the root of the same volume, named <epochMillis>_<name>, and are permanently purged 30 days later (checked on app launch). Browse the trash folder like any other to recover things.

In-app updates — MENU → Update from GitHub fetches the latest GitHub release of this repo and downloads/installs its APK asset. No automatic checks.
