SideCall 1.1

The guard now works when the phone is locked.

Before, if a call arrived while your phone was locked, SideCall's guard only appeared after you unlocked — the most common case (phone asleep in your pocket) was exactly the one it missed. Now, when you answer a call straight from the lock screen, the same black guard and unlock ring cover it immediately. Drag the ring to reach the dialer; your phone stays locked the whole time.

Validated on a real call from deep sleep on the SP-01.

Known limitation: on a call answered while locked, once you reveal (drag the ring) there's no floating re-arm badge until you unlock the phone — Android doesn't let an app draw it over the lock screen. Re-arm returns as soon as you unlock.

Install / update: download app-release.apk below and install over your existing SideCall (adb install -r app-release.apk), or update via Obtainium. Requires Android 12 (API 31). Same signing key as 1.0, so it updates in place.

SideCall 1.0

First release of SideCall — a call-guard for the Sidephone SP-01.

The SP-01 ships without a working proximity sensor, which causes two bugs SideCall fixes:

• Your cheek presses the buttons on an earpiece call. SideCall darkens the screen so nothing your face touches reaches a button; drag the ring three-quarters around to unlock.
• The microphone dies when the screen sleeps. SideCall holds the screen awake for the whole call so the mic never drops.

It's a single overlay over the stock dialer — never the dialer itself, and it never touches your call. Validated on real earpiece, speaker, and Bluetooth calls.

Install: download app-release.apk below and sideload it (adb install -r app-release.apk), then open SideCall once and grant the two permissions. Requires Android 12 (API 31).
