    SagerNet

    SagerNet

    The universal proxy toolchain for Android

    The universal proxy toolchain for Android, written in Kotlin. To use hysteria plugin with version smaller than 1.2.1, the highest compatible version of SagerNet is 0.8.1-rc02. The new protocol is designed to improve UDP performance and provide full replay protection. Using an MTU larger than the upstream interface will only improve speed in some scenarios and may result in UDP packet loss. According to the gfw.report et al's research, when connecting to the impacted VPSs, GFW is likely to block binary protocols unless it is an HTTP, TLS, or SSH connection, or the first 6 bytes of data sent from client to server can be interpreted as printable characters. This suggests in addition to TLS encryption, HTTP Header, this kind of censorship can also be temporarily evaded by only sending printable characters in the first 6 bytes of data.

    FlashDim

    FlashDim

    Dim-adjustable flashlight app for Android 13+ with extra modes

    FlashDim is a modern flashlight application designed specifically for Android devices running Android 13 or newer. It takes advantage of the platform’s newer hardware flashlight dimming capabilities to let users control flashlight brightness levels beyond a simple on/off state, something stock flashlight tools often don’t offer. Because the dimming support depends on hardware exposure of multiple light levels, full functionality only works on devices that support those features in hardware and system APIs. The app includes a range of additional useful features beyond simple dim control, such as customizable shortcut buttons for brightness presets, specialized flash modes like SOS and Morse code signaling, and timed or beat-based flash patterns. It also supports toggling the flashlight quickly through a quick-settings tile and by double pressing the volume buttons via an accessibility service. FlashDim is designed to be private, ad-free, and offline.
