How to fix Fitbit Alta HR that’s not receiving notifications from Android device

Your Fitbit Alta HR stopped showing call alerts, texts, or calendar reminders on your wrist — and you’re not alone. Notification failures are one of the most common issues reported with the Alta HR, and they almost always come down to one of three culprits: the Fitbit app losing its notification access permission, Android’s battery optimization killing the app in the background, or a stale Bluetooth connection between the two devices.

Important note as of 2026: The Fitbit Alta HR was discontinued in 2019 and is no longer receiving firmware updates or active support from Google/Fitbit. The troubleshooting steps below still work for most users, but if notifications remain unreliable after following all of them, the root cause is likely OS-level compatibility drift between Android’s newer notification system and the Alta HR’s aging firmware. In that case, an upgrade may be the only lasting fix — more on that at the end of this guide.

Why Your Fitbit Alta HR Isn’t Getting Notifications

Before jumping into fixes, it helps to understand what’s supposed to happen. The Fitbit app on your Android phone acts as a bridge: it listens for incoming notifications, then relays them to the Alta HR over Bluetooth. This chain breaks at three points:

Notification access revoked — Android may strip the Fitbit app’s notification listener permission after an update or app reinstall.
Battery optimization — Android aggressively kills background apps to save battery. If the Fitbit app is being optimized, it can’t relay notifications while your screen is off.
Bluetooth connection dropped — A stale or corrupted Bluetooth pairing prevents the relay from completing even when the app is running fine.

Start with Fix 1 and work down the list in order. Most users resolve this within the first three steps.

Fix 1: Restart the Fitbit Alta HR

A restart clears the tracker’s memory and re-establishes its connection to the Fitbit app. This resolves notification issues for a significant number of users.

To restart your Fitbit Alta HR:

Plug the charging cable into a USB port on your computer or a UL-certified wall charger.
Clip the other end of the charging cable to the port on the back of the tracker. You’ll feel the magnetic pins lock in — the tracker will vibrate and show a battery icon.
Press the button on the charging cable 3 times within 8 seconds, pausing briefly between presses.
When you see the Fitbit logo appear and the tracker vibrates, the restart is complete.
Unplug the tracker and check if notifications resume.

Fix 2: Check Do Not Disturb and Silent Mode on Your Phone

This is the most overlooked fix. If your Android phone is set to Do Not Disturb, Silent, or Priority mode, the Fitbit app cannot relay those silenced notifications to your tracker — because the phone itself is suppressing them.

Swipe down from the top of your Android screen to open Quick Settings.
Confirm that Do Not Disturb (the crescent moon icon or “DND” label) is off.
Check that your phone’s ringer is not set to silent — even in vibrate-only mode, some Samsung and Pixel models suppress notification forwarding to connected devices.
If you use Focus Mode or Bedtime Mode (available on Android 9 and later), confirm it’s disabled or that Fitbit is whitelisted as an allowed app within that mode.

Fix 3: Grant and Refresh Notification Access in the Fitbit App

The Fitbit app requires explicit notification access permission to forward alerts to your tracker. This permission is separate from the standard app notification permission and gets revoked more often than users realize — particularly after Android OS updates.

Step 1: Enable notification access for the Fitbit app

Open your phone’s Settings app.
Go to Apps (or Apps & notifications on some Android versions).
Tap the three-dot menu (top right) and select Special app access.
Tap Notification access.
Find Fitbit in the list and make sure the toggle is turned on.
If it was already on, toggle it off, wait 10 seconds, then toggle it back on to refresh the permission.

Step 2: Enable notifications inside the Fitbit app

Open the Fitbit app on your Android phone.
Tap your profile photo (top left) to open your account.
Tap the Alta HR device tile.
Tap Notifications.
Enable Call Notifications, Text Notifications, and Calendar Alerts individually.
You’ll be prompted to confirm the connection. Follow the on-screen steps.

Fix 4: Disable Battery Optimization for the Fitbit App

Android’s battery optimization feature is designed to extend battery life by putting background apps to sleep. Unfortunately, it also prevents the Fitbit app from running continuously in the background — which means no notifications are forwarded while the screen is off.

For most Android phones (Android 9 and later):

Open Settings → Apps (or Apps & notifications).
Tap Fitbit from the app list.
Tap Battery (or App battery usage).
Select Unrestricted (not “Optimized” or “Restricted”).

For Samsung Galaxy phones:

Open Settings → Apps.
Tap Fitbit → Battery.
Under “Battery usage,” select Unrestricted.
Also check: Settings → Battery and device care → Battery → Background usage limits — make sure Fitbit is not listed under “Sleeping apps” or “Deep sleeping apps.” If it is, remove it.

For Google Pixel phones:

Open Settings → Apps → Fitbit.
Tap Battery → Battery optimization.
Switch the dropdown to “All apps,” find Fitbit, and set it to Don’t optimize.

After changing these settings, force-close the Fitbit app and reopen it, then test notifications.

Fix 5: Reset the Bluetooth Connection

A corrupted Bluetooth pairing is responsible for many persistent notification failures. Forgetting the device and re-pairing it fresh often resolves issues that none of the above fixes address.

On your Android phone, open Settings → Bluetooth.
Find Fitbit Alta HR in the list of paired devices.
Tap the gear icon (or the name) and select Forget (or “Unpair”).
Restart your phone.
Restart your Alta HR (follow the charging cable restart steps from Fix 1).
Open the Fitbit app → tap your profile → tap Alta HR → tap Set Up a Device.
Follow the pairing process from scratch.
Once paired, go back into the Alta HR device settings and re-enable notifications (see Fix 3, Step 2).

Fix 6: Update the Fitbit App and Sync Your Tracker

An outdated Fitbit app can introduce notification bugs. Check that you’re running the latest version:

Open the Google Play Store and search for Fitbit.
If an Update button appears, tap it and wait for the update to complete.
After updating, open the Fitbit app and force a manual sync: tap the Today tab → swipe down on the screen to trigger a sync.
Keep your Alta HR within 30 feet of your phone during this process.

Fix 7: Try the “Fit Notifications” Third-Party App

If the built-in notification system remains unreliable, the third-party Android app Fit Notifications offers an alternative notification relay system. It works by creating its own Notification Listener Service that forwards notification content directly to the Alta HR, bypassing the Fitbit app’s built-in relay.

Setup steps:

Install Fit Notifications from the Google Play Store.
Open the app and grant it Notification Access when prompted.
Select your Fitbit Alta HR from the device list.
Choose which apps’ notifications you want forwarded (messages, email, calendar, etc.).
The app runs as a background service — grant it the same Unrestricted battery access described in Fix 4.

Many Alta HR users who couldn’t resolve notifications through the official Fitbit app have had success with this approach.

Fix 8: Reinstall the Fitbit App

If all else fails, a clean reinstall clears corrupted app data that can cause persistent notification failures.

On your Android phone, long-press the Fitbit app icon.
Tap Uninstall (or go to Settings → Apps → Fitbit → Uninstall).
Restart your phone.
Reinstall the Fitbit app from the Google Play Store.
Log back in and re-pair your Alta HR (it will appear as a remembered device in your account).
Re-enable notifications in the app settings (Fix 3, Step 2).

When to Consider Upgrading

If you’ve worked through all of these fixes and notifications remain unreliable, the honest answer is that the Alta HR’s age is working against you. The device was discontinued in 2019 and runs firmware that predates Android’s modern notification stack. As Android versions advance, compatibility with unsupported devices degrades — and there’s no firmware update coming to bridge that gap.

The current Fitbit lineup offers full notification support with active software updates. Here are the two best replacements at different price points as of 2026:

Budget pick: Fitbit Inspire 3 (~$99)
The spiritual successor to the Alta HR — slim, lightweight, long battery life (up to 10 days), call/text/calendar notifications, 24/7 heart rate, SpO2 monitoring, and stress management. Compatible with Android 9 and later.
Buy on Amazon

Premium pick: Fitbit Charge 6 (~$160)
Adds built-in GPS (no phone needed for accurate workout tracking), ECG sensor, Google Maps navigation, Google Wallet payments, and YouTube Music controls. Best for users who want a fitness tracker that doubles as a light smartwatch.
Buy on Amazon

Both devices pair seamlessly with Android, maintain full notification support, and receive regular firmware updates — which eliminates the compatibility issues that plague the Alta HR on modern Android versions.

Note: Amazon links should be spot-checked before publishing as product listings may change.
