I created this app because my Xiaomi has some bugs during the call and with my face I close the call or mute the microphone accidentally. The application does nothing but lock the screen when the phone is brought close to the ear during a phone call. Some special permissions are needed to lock the screen. If the application does not remain active in the background, disable battery optimizations on the app settings. No ROOT required

Quicksy is a spin off of the popular Jabber/XMPP client Conversations with automatic contact discovery. You sign up with your phone number and Quicksy will automatically—based on the phone numbers in your address book—suggest possible contacts to you. Under the hood Quicksy is a full-fledged Jabber client that lets you communicate with any user on any publicly federating server. Likewise users on Quicksy can be contacted from the outside simply by adding +phonenumber@quicksy.im to your contact list. Aside from the contact sync the user interface is deliberately as close to Conversations as possible. This allows users to eventually migrate from Quicksy to Conversations without having to relearn how the app works. Suggested contacts consists of other Quicksy users and regular Jabber/XMPP users who have entered their Jabber ID into the Quicksy Directory (https://quicksy.im/#get-listed). NOTE: To enter (https://quicksy.im/enter/) your Jabber ID in the Quicksy Directory an one time registration fee is required. Read the Privacy Policy (https://quicksy.im/#privacy) for more info.

Rattlegram lets you transmit short text messages over COFDMTV encoded audio signals. COFDMTV is based on COFDM (coded orthogonal frequency-division multiplexing) technology:160 ms long OFDM symbols6.25 Hz per sub-carrier1/8 guard intervaldifferentially encoded PSK (phase-shift keying) modulationsystematic polar codes for forward error correctionCurrently Modes 14, 15 and 16 are supported: Using either SPC(2048, 1392), SPC(2048, 1056) or SPC(2048, 712) with CRC32C aided SCL decoding and differential QPSK modulation for the payload. Only a bandwidth of 1600 Hz is needed and the transmission of either 85, 128 or 170 bytes take about one second with the leading noise and fancy header disabled.

RecollDroid is an Android front end to the Recoll full text search engine typically used to index all of your desktop/server files. For more information on Recoll, see https://www.recoll.org RecollDroid consists of an andriod ui and a thin server layer providing a RestAPI interface to the Recoll software. It uses Recoll's python API and supports multiple users securely via basic auth over https. The server layer makes use of FastAPI to provide the restful endpoints for the UI. It contains no authentication code itself but depends on a proxying layer to ensure only validated users can connect. The supported setup is to use the Nginx reverse proxy to perform basic auth together with the unit app server to host the recoll rest api.
