If your Holy Stone HS720 camera is not working, the problem is usually tied to power, app pairing, firmware, or a gimbal initialization issue.
This guide breaks down the most common causes and the fastest fixes so you can isolate the fault without guesswork.
What “Holy Stone HS720 camera not working” usually means
When pilots say the HS720 camera is not working, they may mean different symptoms: no live video in the app, a black screen, frozen feed, shaky footage, a camera that will not tilt, or recordings that do not save correctly.
The HS720 uses a Wi-Fi FPV connection, a mobile app, and a stabilized camera assembly, so a problem in any one of those layers can disrupt video.
The first step is to identify the exact symptom.
A camera that powers on but shows no image requires a different fix than a gimbal that will not move or a microSD card that is not recording properly.
Common reasons the HS720 camera stops working
- Phone is not connected to the drone’s Wi-Fi network correctly
- The app does not have camera, local network, or storage permissions
- Firmware on the drone or app is outdated
- The gimbal or camera needs a reset after impact or power interruption
- microSD card is incompatible, full, corrupted, or not inserted properly
- Camera cable or connector is loose
- Low battery voltage is affecting the camera and Wi-Fi module
- Environmental interference is weakening the video link
Check the basic setup first
Before opening menus or reinstalling apps, confirm that the drone is powered correctly and that the camera hardware is intact.
A simple setup issue often looks like a camera failure.
Verify battery and power sequence
Use a fully charged battery and power on the drone on a stable surface.
Wait for the drone to finish its startup sequence before launching the app.
If you power up the app too early, the phone may connect to the wrong Wi-Fi signal or fail to establish the live feed.
Inspect the camera and gimbal
Look for any visible obstruction, bent bracket, or debris around the camera housing.
If the drone had a hard landing, the camera ribbon or gimbal arm may be displaced.
Even a small misalignment can stop the image from appearing correctly.
Fix the app and Wi-Fi connection
For most pilots, the Holy Stone HS720 camera not working problem begins with the mobile connection rather than the lens itself.
The drone camera feed depends on a clean Wi-Fi link between the aircraft and the phone.
Reconnect to the correct Wi-Fi network
Open your phone’s Wi-Fi settings and connect to the drone’s network before launching the control app.
If your phone auto-connects to a home or cellular hotspot, the live video stream may never initialize.
Turn off mobile data temporarily
Some phones switch away from the drone’s Wi-Fi if they detect weak internet access.
Disabling mobile data during setup can help the device stay on the drone connection long enough to load the feed.
Grant all required permissions
The app may need camera, location, storage, and local network permissions to function properly on iOS and Android.
If the app cannot access storage, recordings may fail.
If local network access is blocked, the preview window may stay blank.
Restart both the drone and the phone
Power the drone off, close the app completely, restart the phone, and reconnect.
A fresh session clears temporary pairing errors that often cause frozen or black screens.
Check the microSD card and recording settings
If live view works but files do not save, the issue may be with the memory card rather than the camera itself.
The HS720 typically relies on a compatible microSD card for onboard recording.
Use a compatible card
Try a known-good microSD card from a reputable brand.
Card compatibility matters because slower or counterfeit cards can cause recording errors, lag, or file corruption.
Format the card properly
Back up any important files, then format the card in a computer using the file system recommended by the manufacturer.
A corrupted card can cause the camera to behave as though it is malfunctioning even when the sensor is fine.
Check capacity and insertion
Make sure the card is fully seated and not at capacity.
If the card is locked or physically damaged, the drone may not write video files at all.
Reset the camera and gimbal
The HS720 uses a stabilized camera assembly, and after a crash or abrupt shutdown the gimbal may need to reinitialize.
If the camera is stuck at an angle or not responding to tilt controls, a reset may help.
Power cycle with the drone on level ground
Place the drone on a flat surface, power it off, then back on without moving it during startup.
This allows the gimbal and camera to calibrate from a neutral position.
Check for physical obstruction
Dust, packaging foam, or a misaligned protective mount can restrict camera movement.
Remove anything touching the camera housing and test the tilt function again.
Inspect the connector after impact
If you are comfortable opening the housing, check whether the camera ribbon cable or connector has loosened.
A disconnected ribbon can produce a black image even though the drone appears normal otherwise.
If the drone is under warranty, contact Holy Stone support before opening the body.
Update firmware and app software
Firmware mismatches can cause unstable FPV video, pairing failures, or camera lag.
Updating both the drone firmware and the control app can resolve software-level issues that mimic hardware failure.
Install the latest app version
Older app versions may not work well with newer phone operating systems.
Update from the official Apple App Store or Google Play Store, then clear cached data if the app still misbehaves.
Update drone firmware carefully
Follow the Holy Stone instructions for firmware updates exactly.
Keep the battery charged, maintain a stable connection, and do not interrupt the process.
A failed firmware update can cause additional camera or flight instability.
Rule out signal interference and distance problems
The HS720 camera feed can degrade if the drone is too far away or if the surrounding RF environment is congested.
Wi-Fi video systems are sensitive to obstructions, especially in urban areas with many networks.
- Test the camera in an open outdoor area
- Keep the drone close during troubleshooting
- Avoid power lines, routers, and dense buildings
- Minimize direct interference from Bluetooth accessories
If the feed works near the drone but cuts out at distance, the camera may be fine and the issue may be signal quality instead.
When the camera works intermittently
An intermittent feed often points to one of three things: weak battery output, loose wiring, or a stressed Wi-Fi module.
If video appears only sometimes, test the drone with another phone, another app install, and another microSD card to narrow the cause.
Also pay attention to heat.
Extended use in hot conditions can affect electronics performance, especially if the drone has been sitting in direct sun before takeoff.
When to contact Holy Stone support
Reach out to Holy Stone support if the camera remains black after checking the app, Wi-Fi, firmware, and SD card, or if the gimbal is physically damaged.
Support may ask for photos, a short video, your order details, and the exact symptoms so they can determine whether a replacement part or repair is needed.
If the drone is still under warranty, avoid disassembling the body or forcing the camera mount.
That can complicate replacement eligibility.
Fast troubleshooting checklist
- Fully charge the battery and power the drone on first
- Connect the phone to the drone Wi-Fi network
- Close and reopen the app
- Grant camera, storage, and network permissions
- Try a different microSD card
- Restart the drone on level ground
- Update the app and firmware
- Test in an open area with less interference
Running through these steps in order usually reveals whether the Holy Stone HS720 camera not working issue is caused by software, connection settings, storage, or hardware damage.
