Auto Hotspot: Car Tethering

Hotspot automation stopped working after the Android 16 or 17 update? AutoHotspot still does it — no root, no Shizuku, no PC required.

AutoHotspot automatically turns your phone's WiFi hotspot (tethering) on and off. As soon as you get in the car and your phone connects to your car's Bluetooth (car stereo / head unit), the mobile hotspot turns on, so your head unit, tablet or dash cam gets online right away. When you leave and Bluetooth disconnects, it can turn the tethering back off to save battery and data. No more digging into Settings every time.

[Why it still works on Android 16 and 17]
Starting with Android 16, tethering permissions are tighter: apps can no longer switch the hotspot on through the system API, which is why so many hotspot automation setups stopped working after the update. AutoHotspot takes a different route. It uses Android's Accessibility Service to pull down the quick-settings panel and tap the "Personal Hotspot" tile for you — exactly the action you would do by hand. No root, no Shizuku, no ADB, no computer.

[Key features]
• Connect to your chosen car Bluetooth → WiFi hotspot turns on automatically
• Bluetooth disconnects (you leave) → automatic tethering turns off (optional)
• Works even on the lock screen, no unlocking needed
• Remembers where your hotspot tile is, so it keeps working trip after trip
• Customize which Bluetooth devices trigger it and the hotspot tile keywords — compatible with most brands and languages
• Built-in test and diagnostics pages show exactly which step succeeded or failed
• No root, no Shizuku, no scripting: hotspot automation that just works

[Getting started]
Run one successful test with the screen on first; the app remembers the tile's position so it can do it automatically later, even on the lock screen. Every phone toggles its hotspot differently, so start with the free trial and run the built-in test before you buy.

[Permissions & privacy]
• Accessibility Service: used only to pull down the quick-settings panel and tap the "Personal Hotspot" tile. It never reads, collects, or uploads any screen content.
• Bluetooth: used only to detect whether your chosen car is connected, as the trigger condition.
• Diagnostic logs stay on your device and are never sent anywhere.

[Pricing]
7-day free trial. After that, watch a short rewarded ad anytime for more free days, or make a one-time purchase to unlock it for life — no subscription, no contract.

[Great for]
• Car navigation and music streaming over your head unit's WiFi
• Android Auto head units and aftermarket car stereos that need internet
• Sharing your phone's mobile data with a tablet, laptop or dash cam
• Anyone whose hotspot automation broke after upgrading to Android 16 or 17
• Anyone tired of switching a portable hotspot on and off by hand every day

Let AutoHotspot handle the tethering, so getting online in the car is one less thing to think about.
