What this connection problem means
If your Holy Stone HS175 keeps disconnecting from phone, the issue is usually not the drone itself but the link between the smartphone, the Holy Stone app, and the drone’s Wi‑Fi signal.
This article explains the most common causes, the fastest fixes, and the settings that improve FPV stability.
The HS175 is a Wi‑Fi FPV drone, so it depends on a strong short-range connection and a compatible phone setup.
Small changes in app permissions, network settings, or interference can make the live video cut out unexpectedly.
Why the Holy Stone HS175 disconnects from a phone
The HS175 uses a direct Wi‑Fi connection for first-person-view video and app control features.
That means it can be affected by phone operating system settings, interference from nearby networks, battery level, or a weak drone-to-phone link.
- Wi‑Fi interference: Other 2.4 GHz devices, routers, and crowded public spaces can disrupt the signal.
- Phone switching networks: Some phones try to move from the drone’s Wi‑Fi to mobile data or another saved network.
- App permission issues: The Holy Stone app may need location, local network, and camera permissions to work correctly.
- Outdated app or firmware: Older software can reduce compatibility and connection reliability.
- Distance and obstruction: The connection weakens quickly if the phone is too far from the drone or blocked by walls and bodies.
- Low battery: A weak drone battery can reduce Wi‑Fi performance and cause video dropouts.
First checks to do before changing settings
Before adjusting advanced options, verify the basics.
Many disconnect issues are caused by simple setup mistakes that take only a minute to correct.
- Charge the drone battery and phone to at least 50 percent.
- Turn on the drone, wait for it to fully initialize, and confirm the LED indicators show normal status.
- Use the official Holy Stone app recommended for the HS175.
- Keep the phone within close range during setup, ideally a few feet from the drone.
- Test outdoors in an open area away from routers, Bluetooth speakers, and power lines.
How to reconnect the HS175 to your phone properly
The most reliable method is to start fresh each time and avoid background apps that may interfere.
If the HS175 keeps disconnecting from phone during setup, follow a clean reconnection sequence.
- Turn off Wi‑Fi on the phone if another saved network is nearby and automatically reconnecting.
- Launch the Holy Stone app before connecting to the drone’s network.
- Power on the HS175 and wait until its Wi‑Fi signal appears in the phone’s network list.
- Join the drone’s Wi‑Fi network directly in the phone settings if the app requires it.
- Return to the app and confirm live video appears before taking off.
- Disable VPN services and close bandwidth-heavy apps in the background.
If the app loses access after connecting, force-close it and repeat the sequence.
A clean restart can clear temporary handshake errors between the phone and the drone.
Phone settings that often cause disconnects
Modern smartphones include security and optimization features that can interrupt a drone Wi‑Fi session.
These settings are useful for daily use but may interfere with the HS175.
Disable mobile data switching
Some Android and iPhone models try to maintain internet access by leaving weak Wi‑Fi networks.
Because the HS175 connection does not provide normal internet, the phone may drop the drone network unless you keep it active manually.
- Turn off smart network switching or adaptive connectivity if your phone has it.
- Temporarily disable mobile data while flying.
- Forget other nearby Wi‑Fi networks if your phone connects to them automatically.
Check app permissions
The Holy Stone app may need permissions that are easy to miss.
If these are blocked, the app may appear connected but fail to maintain the link.
- Location: Often required for Wi‑Fi scanning on Android.
- Local network: Needed on iPhone for device-to-device communication.
- Camera: Required for in-app functions and possibly code scanning.
- Photos and storage: Needed if you save footage from the app.
Turn off battery optimization for the app
Battery-saving features can suspend background processes and force the app to reconnect repeatedly.
On Android, disable battery optimization for the Holy Stone app.
On iPhone, avoid Low Power Mode during setup and flight if possible.
App and firmware updates that improve stability
Outdated software is a common cause of a weak or unstable FPV connection.
The Holy Stone app and HS175 firmware should be current whenever possible.
Check the app store for the latest version of the Holy Stone app.
Then review the manufacturer’s instructions for firmware updates, which may be delivered through the app or a support page.
- Update the app after reinstalling it if crashes or freezes persist.
- Use a stable phone OS version when possible, especially after major Android or iOS releases.
- Reboot the phone after updating to clear cached network conflicts.
Best flying conditions for a stable phone connection
The HS175 performs best in open areas with minimal radio interference.
Since the drone uses 2.4 GHz Wi‑Fi, the environment matters as much as the phone itself.
- Fly in open fields or large outdoor spaces.
- Avoid dense apartment buildings, stadiums, and shopping centers.
- Keep the drone close during the first seconds of connection.
- Do not place the phone behind metal surfaces, thick cases, or bags during setup.
- Keep Bluetooth accessories to a minimum while testing.
If the issue only happens indoors, the cause is likely interference rather than a faulty drone.
Testing in a different location helps confirm whether the problem is environmental.
When the problem may be the phone
Not every disconnect points to the drone.
Some phones, especially older models or heavily customized Android devices, handle local Wi‑Fi device connections less reliably.
Signs the phone may be the issue include frequent network drops only on one device, successful connection on a second phone, or app instability after a recent operating system update.
If possible, test the HS175 with another compatible smartphone.
- If the second phone works normally, your original device likely has a settings or compatibility issue.
- If both phones disconnect in the same way, the problem is more likely related to the drone, app, or environment.
Resetting the connection without resetting the drone
You usually do not need a full factory reset to resolve disconnects.
Start by clearing network confusion on the phone and the app.
- Forget the HS175 Wi‑Fi network on the phone.
- Restart the drone, the phone, and the Holy Stone app.
- Reconnect in a clean open area.
- Test the live video feed before moving the drone far away.
If the app continues to disconnect, reinstall it and repeat the pairing process.
A reinstall can clear corrupted app data without changing the drone’s hardware settings.
When to contact Holy Stone support
If the Holy Stone HS175 keeps disconnecting from phone after you have updated the app, checked permissions, and tested in a low-interference location, the drone may have a hardware or Wi‑Fi module issue.
Contact Holy Stone support with the following details:
- Phone model and operating system version
- App version
- Drone firmware version if available
- Steps already tried
- Whether the issue happens on more than one phone
Providing this information helps support determine whether the problem is software-related, environmental, or tied to a specific drone unit.
