Gravity Screen Pro MOD APK v3.4.1 (Pro Unlocked, Pocket Sensor & Zero Drain) [2026]

What Is Gravity Screen Pro?

Gravity Screen Pro transforms how you interact with your smartphone by eliminating the need to press the physical power key. Smartphone mechanical power buttons experience thousands of presses every month. Over time, physical switch contacts degrade, leading to unresponsive clicks, sticky buttons, or permanent hardware failure. Gravity Screen Pro solves this problem through intelligent background sensor monitoring.

The application continuously reads low-power sensor data from your device's built-in accelerometer and infrared proximity sensor. When you slide your handset into your pocket, the app registers the downward tilt and proximity coverage, turning off the screen instantly. When you pull the phone out of your pocket, the sensor register clears and the display wakes up automatically. It delivers a touch-free experience that feels completely natural during daily mobile usage.

Unlike basic screen-off widgets, Gravity Screen Pro operates via sophisticated state-machine algorithms. It differentiates between intentional pocketing, casual desk placement, and accidental hand brushing. This intelligence prevents unintentional screen activation while walking, running, or cycling. The result is a seamless workflow that protects physical buttons while conserving screen battery consumption.

Key Pro Unlocked Capabilities and Core Features

The standard free version of Gravity Screen provides basic tilt-based sleep functions but restricts critical calibration parameters behind paywalls. Gravity Screen Pro unlocks the full suite of automation tools:

• Pro Table Sensor Angles: Set independent angle thresholds for both face-down and face-up table placements, allowing flat and propped-up viewing angles.
• Any Direction Pocket Detection: Recognizes pocket insertion regardless of whether the phone is inserted top-down, bottom-down, or sideways in loose coat pockets.
• Turn Screen On by Motion: Wakes the display when you lift or move the phone from a resting state, using micro-motion acceleration filtering.
• Extended Motion Timeout Controls: Allows you to configure custom inactivity timers, preventing continuous sensor drain during extended idle periods.
• Per-App Exclusion Whitelist: Automatically pauses sensor automation whenever designated games, e-readers, or video streaming apps are running in the foreground.
• Delayed Screen Lock Timers: Separates display turn-off from full security locking, letting you wake the device quickly without re-entering credentials.
• Headset and Bluetooth Rules: Customizes sensor behavior when wired headphones or Bluetooth audio accessories are actively connected.
• Completely Ad-Free Interface: Strips out banner advertisements and analytical tracking libraries, delivering a clean and battery-efficient setup menu.

Sensor Architecture and Detection Algorithms

Understanding how Gravity Screen Pro monitors physical motion explains why it performs with high accuracy across diverse hardware configurations. The software coordinates two distinct hardware sensors managed by the Android SensorManager framework:

1. The Accelerometer and Gravity Vector

The tri-axial accelerometer measures acceleration forces along the X, Y, and Z axes. When your device is stationary, the primary force detected is Earth's gravitational pull (approximately 9.81 m/s²). Gravity Screen Pro calculates the angular pitch relative to the vertical axis:

When the vertical tilt angle exceeds your programmed Pocket Sensor threshold (defaulting between 60° and 90°), the software triggers the pre-sleep state. The Pro version allows fine-grained micro-adjustments down to single-degree precision. This customization accommodates loose jeans, tight tailored trousers, and deep coat pockets where handsets tilt at unusual angles.

2. The Optical Proximity Sensor

Positioned near the top earpiece, the optical proximity sensor emits an invisible infrared pulse to measure nearby obstructions within 3 to 5 centimeters. While the accelerometer verifies orientation, the proximity sensor confirms physical enclosure. Gravity Screen Pro requires both conditions to match before executing a screen-off event in pocket mode. This dual-verification architecture eliminates false triggers when you merely tilt your phone while typing or browsing.

3. Micro-Motion Wake Filtering

Waking the screen through motion uses high-pass acceleration filtering. Rather than monitoring raw gravitational tilt, the motion engine listens for sudden linear acceleration changes. When you reach down and lift your device off a flat surface, the positive Z-axis spike triggers the display wake cycle. The Pro version includes sensitivity damping to ensure gentle desk vibrations or footsteps do not cause erratic display flashing.

Battery Optimization and Doze Mode Management

A frequent concern with background sensor tools is battery consumption. Running the main processor continuously to read accelerometer data can deplete a mobile battery rapidly. Gravity Screen Pro circumvents high power draw using hardware sensor batching and intelligent sleep loops.

Modern Android chipsets incorporate dedicated low-power sensor processing units, often referred to as a Sensor Hub or Context Hub. These micro-controllers process accelerometer vectors independently while the main application processor remains in deep sleep. Gravity Screen Pro registers listeners using Android's low-latency sensor batching flags, allowing the central CPU to sleep while the sensor hub filters orientation data.

To keep the automation reliable across modern OEM Android skins like Samsung OneUI, Xiaomi HyperOS, and OPPO ColorOS, you must configure battery management settings correctly:

• Exclude from Battery Optimization: Navigate to System Settings > Apps > Gravity Screen Pro > Battery, and switch the policy from 'Optimized' to 'Unrestricted'. This prevents Android's Doze mode from freezing the background sensor listener.
• Lock in Memory Overview: Open your recent applications overview, swipe or hold the Gravity Screen Pro app card, and tap the Padlock icon to prevent the system memory killer from purging the process during multitasking.
• Enable Autostart Permissions: On devices running HyperOS or ColorOS, enable the Autostart toggle in the application details menu so that sensor monitoring resumes immediately after phone reboots.
• Configure the Motion Inactivity Timer: Set the 'Turn Screen On by Motion' timeout to 15 or 30 minutes. Once your device remains completely stationary for this duration, the app turns off motion polling entirely until you manually wake the screen once.

Accessibility Service vs. Device Administrator Lock

When setting up screen-locking automation on Android, choosing the correct lock method is essential for a smooth biometric unlocking experience. Gravity Screen Pro provides two distinct methods:

Method 1: Accessibility Service (Recommended)

Modern Android versions support an Accessibility API method called GLOBAL_ACTION_LOCK_SCREEN. When Gravity Screen Pro uses this API, Android treats the event as an organic display sleep rather than an administrative lockdown. As a result, your in-display fingerprint scanner, capacitive power button scanner, and front-camera face unlock continue working normally on the next wake cycle.

Method 2: Device Administrator (Legacy)

Older Android releases rely on the DevicePolicyManager.lockNow() API. While this method locks the display instantly, Android's security architecture flags administrative locks as high-security events. This requires you to enter your PIN, password, or pattern every single time you wake the phone, disabling biometric unlock. This method is only recommended for legacy Android devices running version 8.0 or older.

Step-by-Step Installation and Calibration Guide

Follow these practical setup steps to achieve accurate, reliable sensor automation without false triggers:

Step 1: Install the Package

Download the verified Gravity Screen Pro MOD APK archive directly to your internal storage. Tap the downloaded APK file in your file manager. If prompted, allow installations from unknown sources in your browser or file manager settings, then complete the setup.

Step 2: Grant Core Permissions

Launch Gravity Screen Pro. The app displays an initial setup wizard requesting necessary permissions:

• Accessibility Service: Tap 'Enable', locate Gravity Screen Pro in your Android Accessibility menu, and toggle the switch on.
• Notification Permission: Allow notification access so the app can maintain a lightweight foreground service icon, protecting it from sudden OS process termination.
• Usage Access (Optional): Grant usage stats access if you plan to use the App Exclusion Whitelist for games and video players.

Step 3: Calibrate Pocket Sensor Angle

Hold your phone at the angle it naturally rests when you begin sliding it into your trousers or jacket. For standard jeans pockets, set the Pocket Sensor angle slider between 60° and 70°. If you wear loose cargo trousers or store your phone in a backpack sleeve, increase the threshold to 75° or 80°.

Step 4: Configure Table Sensor Thresholds

Place your smartphone flat on a desk or table. Adjust the Table Sensor downward angle to 10° or less. Enable the 'Table Sensor by Proximity' toggle so that placing the phone face-down cuts screen power immediately. If you want the display to sleep when resting flat face-up, enable the upward table threshold and set it to 5°.

Step 5: Fine-Tune Motion Wake and Exclusion Rules

Toggle on 'Turn Screen On by Motion'. Set the motion sensitivity slider to the middle setting (value 15–20) to prevent light desk bumps from waking the screen. Set the motion timeout slider to 15 minutes. Finally, open the Excluded Applications list and check all streaming services, navigation tools, and gaming apps where uninterrupted display on-time is required.

Troubleshooting Common Configuration Issues

While Gravity Screen Pro is built for stability, differences in manufacturer hardware and firmware can introduce edge-case quirks. Here is how to diagnose and resolve the most common issues:

Issue 1: Screen Turns Off While Reading or Scrolling

If the display sleeps while you are holding your phone upright, your Pocket Sensor angle may be set too conservatively. When reading while reclining on a sofa, the phone often tilts past 60°. To fix this, increase the Pocket Sensor threshold to 75° or 80°, or enable the 'False Turn Off Protection' setting, which delays screen off until the proximity sensor has been covered continuously for at least two full seconds.

Issue 2: The App Closes Overnight

If you wake up in the morning and discover that Gravity Screen is no longer responding to movement, your operating system's background task killer purged the service. Check that the persistent notification icon remains pinned to your Android status bar. If the icon disappears overnight, re-verify your OEM battery saver exceptions and verify that Android's 'Remove permissions if app is unused' toggle is turned off in the app info menu.

Issue 3: Proximity Sensor Remains Active During Media Playback

If waving your hand near the top speaker while watching YouTube or playing games accidentally locks the phone, open Gravity Screen Pro, tap the Excluded Applications button, and place a checkmark next to all media players, web browsers, and gaming titles. The app automatically freezes sensor listening whenever an excluded app occupies foreground focus.

Advanced Tasker and Automation Intent Integration

For power users who orchestrate complex smartphone routines through Tasker, MacroDroid, or Automate, Gravity Screen Pro includes full support for Android Broadcast Intents. Instead of leaving background sensor listeners permanently active, you can instruct your automation host to pause or resume sensor monitoring based on contextual geofencing, Wi-Fi connectivity, or vehicle docking states.

To integrate Gravity Screen Pro with Tasker, configure an Action Intent with the following parameters:

• Pause Sensor Action: Send Intent action com.plexnor.gravityscreenoff.PAUSE_SENSOR to temporarily suspend accelerometer polling when connected to your car Bluetooth or when docking your phone on an in-car magnetic navigation mount.
• Resume Sensor Action: Send Intent action com.plexnor.gravityscreenoff.RESUME_SENSOR when disconnecting from vehicle systems to instantly re-arm pocket and table automation routines.
• Toggle State Action: Send Intent action com.plexnor.gravityscreenoff.TOGGLE_STATE to bind a custom Quick Settings tile or physical convenience button via Key Mapper.

This programmatic control prevents unwanted screen sleep while driving over bumpy terrain, where vertical vibrations could otherwise mimic pocket angle thresholds. It also allows you to disable screen wake automation automatically during night-time Sleep Focus schedules.

Sensor Drift Compensation and Kalman Filtering

Low-cost consumer MEMS accelerometers frequently experience thermal drift and minor sensor offset deviations over extended operating cycles. If a smartphone chassis warms up during fast wireless charging or intense computational workloads, the reported gravitational vector can drift by 2° to 5°. Gravity Screen Pro counteracts this hardware variance using continuous low-pass Kalman filtering.

The Kalman filter dynamically estimates the true gravitational vector by calculating the moving variance of acceleration samples over time. High-frequency noise—such as rapid hand tremors or vehicular road vibration—is filtered out, leaving only the steady-state gravitational angle. This mathematical filtering ensures that your configured 65° pocket angle remains accurate whether your phone is cold in winter or warm during summer travel.

Android 14 and Android 15 Predictive Back Compatibility

Recent Android platform updates introduced predictive back gestures and strict edge-to-edge window enforcement across all userland applications. Gravity Screen Pro v3.4.1 adapts seamlessly to these architectural modifications. Its configuration interface renders correctly beneath transparent system navigation bars without obscuring slider controls or toggle switches.

Furthermore, Gravity Screen Pro registers with Android's modern OnBackInvokedCallback dispatcher, ensuring that navigating through deep setting menus never causes unexpected application crashes or service freezes. All background listeners comply with Google Play's foregroundServiceType="specialUse" framework, ensuring uninterrupted automation on the latest generation of flagship smartphones.
