ShieldTap - Call Touch Guard

Ever had a call accidentally switch to video, go on mute, or hang up because your cheek touched the screen? Budget Samsung Galaxy phones (A series, FE series, Quantum series) use camera-based virtual proximity sensors instead of hardware IR sensors. These virtual sensors are slow and unreliable, causing frequent accidental screen touches during calls. ShieldTap places a touch-blocking overlay on your screen during calls to prevent these accidental touches. ■ Basic Mode (Free) • Manual on/off via side tab button on screen edge • Activate before making a call ■ Plus Mode (In-app purchase) • Automatically activates when a call connects • Automatically deactivates when the call ends • One-time purchase, yours to keep ■ Touch Lock (non-call) • For watching videos, wet hands, handing the phone to a child, etc. • Transparent overlay keeps the screen visible while blocking touches • Move the side tab button anywhere — left/right, up/down ■ Accessibility Service • ShieldTap uses the Android AccessibilityService API • Used only for its core feature: showing the touch-blocking blind and side tab button on screen • Does not read screen content, change settings, control other apps, or record calls • Works only after you turn it on in Settings, and can be turned off anytime ■ Privacy • Does not collect, store, or transmit personal data or call content • Internet is used only to verify Google Play in-app purchases • Open source (source code available on GitHub) ■ Target Devices • Smartphones with camera-based virtual proximity sensors • Galaxy S25 FE, S24 FE, S23 FE, S22 FE • Galaxy A17, A16, A15, A14, A13 • Galaxy Quantum 6, 5, 4, 3 • Other Android devices with virtual proximity sensors
