Assistive Nav gives you a floating back key and home button when a physical key is worn out, the bottom of the screen is cracked, or the gesture area simply stopped responding. Keep using your phone normally until it is repaired.
A dead navigation area can make a phone almost useless: you open an app and cannot get out of it. Assistive Nav places a round floating button or a small bar of soft keys on the part of the screen that still works.
▸ Set up in about a minute
1. Open Assistive Nav and read what the accessibility service does and never does.
2. Tap Agree, and Android's Accessibility settings open. Find Assistive Nav and switch it on.
3. A key bar appears. Drag it away from the damaged area and change its style on the app's home screen.
▸ A round button or a full key bar
• Floating ball: one round button that stays on top of every app. Tap it to go back.
• Key bar: a row of soft keys you can drag to any height, or a vertical bar fixed to the left or right edge.
• Lock the position so a shaky hand does not move it.
▸ Replace the keys that stopped working
• Back, Home and Recents, the three basic navigation keys.
• Power menu on screen when the side key is stiff or broken, to restart or turn the phone off.
• Lock screen (Android 9+): turn the display off without pressing the side key.
• Screenshot (Android 9+): no volume-and-power combination needed. The keys step aside for the shot.
• Notifications and Quick settings when the top of the screen is hard to swipe.
• Choose your keys and their order. Every key is free.
▸ Easy to see, easy to press
• Keys from 75% up to double the normal size, good for larger fingers and for parents or grandparents.
• Opacity from light to solid, so the keys stand out on any background.
• A gentle vibration on each press confirms it worked. You can turn this off.
▸ Out of the way at the right moment
• Hidden automatically while the keyboard is open.
• Optional: hidden in full screen videos and games.
• A quiet notification with Show, Hide and Hide 10 s, plus a Quick Settings tile.
▸ When the keys disappear
Some phones close background services to save battery. Assistive Nav shows when this happens and walks you through restarting the service.
▸ What the Accessibility API is used for
Android only lets an app press Back, Home and Recents through its AccessibilityService API. Assistive Nav uses it only to perform the single action you tap and to show its keys above other apps. No data is collected through the Accessibility API: the service cannot read your screen, does not see your typing, including passwords, and never taps or swipes by itself. It is off by default and you can turn it off at any time in Settings → Accessibility.
▸ Other permissions, in plain words
• Notifications (Android 13+): only for the Show / Hide controls. You can refuse; the keys still work.
• Internet: for ads, purchases, anonymous usage counts and crash reports. Nothing from your screen is sent.
▸ Premium is optional
All keys and both styles are free. The free version shows a banner on the app's home screen and an occasional full-screen ad when you go back to it, never on the keys and never over other apps. Premium removes the ads, lets you assign a long-press and a double-tap action to the floating ball (for example Home and Recents), and adds four extra skins: Midnight, Chalk, Ember and Glass. It comes as a monthly or yearly subscription, or as a single lifetime purchase. Subscriptions renew automatically; cancel at any time in Google Play.
▸ Privacy
No account is needed. Your settings stay on your device.
Assistive Nav does not repair hardware; it gives you working keys on screen.
