If CameraFi Live stops playing when your Android screen turns off, first find out whether the display merely timed out, you manually locked the phone, or the video source or live broadcast actually stopped. Test those events separately; a battery setting or charger may help identify a cause, but neither is a guaranteed fix across phones and app versions.
Keep CameraFi visible for the first test, then compare timeout with manual locking, and repeat while charging on a stable network. If only locking triggers the problem, inspect CameraFi’s background-use controls and record the result. CameraFi’s public guide describes video sources but does not document a guaranteed screen-off playback fix.
First identify what actually stopped
“Stopped” can describe several different outcomes. The screen may go dark while the video and broadcast continue; playback may pause in CameraFi; the app may close or disappear; the network connection may drop; or the outgoing YouTube live broadcast may end. These are not interchangeable symptoms, and changing phone settings before distinguishing them can obscure the cause.
Choose a short, familiar video source and observe CameraFi while the display is on. Note whether the source plays, whether the app shows that it is still broadcasting, and whether the YouTube viewer can still see the stream. If practical, check the viewer from a second device: the phone’s screen going dark alone does not tell you whether the outgoing broadcast ended.
When the symptom occurs, write down what you observe rather than interpreting it immediately. Did the video freeze in the app? Did CameraFi return to the home screen? Did YouTube show that the live broadcast ended, or did only your viewing screen stop updating? A clear distinction gives you a useful report and prevents you from treating a playback issue as a network failure.
A live camera or screen broadcast also differs from playing a prerecorded file as the source. CameraFi’s Android beginner guide describes video files as one of the available source types, but does not promise that a file keeps playing after the phone locks. If your goal is an unattended prerecorded loop rather than a phone-based live production, that difference matters when you consider another workflow.
Test with CameraFi visible
Start with the simplest baseline: keep CameraFi open and visible, use the same video and network you normally use, and let the video play for a few minutes. This is a short diagnostic observation, not a claim that a longer run will behave the same way. If the video or broadcast stops while the display remains on, screen locking is not necessary to trigger the failure. Investigate the source, app state, network or broadcast setup before focusing on screen-off behaviour.
If it continues while visible, temporarily increase the display timeout through Android’s display settings. The setting is usually under Display or Screen, though the name and available choices vary by manufacturer and Android release. Keep the phone awake long enough to see whether the source continues past the timeout you normally encounter. Restore the original timeout after the test if you do not want to leave it changed.
There is a useful difference between letting the timeout happen and pressing the power button yourself. Timeout tests whether playback survives the display going dark after inactivity. Manual locking, covered next, tests a deliberate lock action that can change how the device treats the app. Do not combine both changes in one run: if you extend the timeout and lock manually at the same time, the result is harder to interpret.
If the video runs while CameraFi is visible but stops at timeout, repeat the baseline before changing other variables. Confirm that the same source, connection and broadcast state were in use. A single interruption can have more than one explanation; repeatability makes the next comparison more informative.
For a channel built around prerecorded material, decide whether you need CameraFi’s on-device controls or simply a continuous sequence of files. Our guide to scheduling video playback in OBS for a continuous stream covers a different production workflow; it is not a setting that repairs CameraFi, but it helps clarify whether a phone must remain part of the operation.
Test manual locking separately
After the visible and timeout checks, return to the same setup and let the display stay on. Start playback, then press the power button once to lock the phone. Observe from a second device if possible, and note the time and what happens in CameraFi when you wake the screen again. Avoid changing battery controls before this comparison so you know what the unmodified setup does.
If timeout leaves the stream running but manual lock stops it, that points to a difference associated with locking or the app’s transition out of the foreground. It does not prove which Android rule or CameraFi behaviour is responsible. If both events stop playback, the common screen-off condition is worth investigating, but it still does not establish a specific cause. If neither stops it in a repeat test, note that too; the original failure may depend on a different source, network or period of inactivity.
Record which part failed. A paused source with CameraFi still open is a different report from an app that closes, and both differ from an ended YouTube broadcast. CameraFi’s screen-streaming tutorial explains broadcast controls, but it does not establish that a video source should continue through manual locking. Use product documentation to understand the workflow, not as proof that every screen-off case is supported.
Do not leave a phone locked for a long unattended trial just to see what happens. For a controlled diagnosis, make a short observation, then wake the screen and confirm the app state. If you need a channel to run while you sleep or leave the premises, a brief test cannot certify that this phone-and-app combination will remain reliable unattended.
Repeat while charging and on a steady connection
Repeat the same relevant test with the phone connected to its normal charger and on a stable network. Keep the source, CameraFi state and lock method the same as before. If the result changes only when charging, record that contrast. Android’s documentation says connecting a charger exits Doze, so a charging comparison can indicate that power management deserves attention; it does not show that a charger fixes a CameraFi-specific problem.
A charger can also change practical conditions such as battery level over the test, while a different Wi-Fi or mobile connection changes network conditions. Avoid moving between networks during the comparison. If you are testing on mobile data, note that; if you are on Wi-Fi, note whether the signal was stable where the phone sat. You are looking for a repeatable difference, not trying to produce a universal result from one run.
If charging makes no difference, that is useful evidence too. It makes a simple Doze-related explanation less compelling, but does not rule out app behaviour, another power policy, a source issue or a network interruption. If the stream ends both plugged in and unplugged, capture the exact event and continue to the app-specific controls rather than repeating the same test indefinitely.
Do not buy a charger or accessory on the assumption that it will keep the broadcast alive. The charging comparison is diagnostic. It is not a recommendation to use a particular product, and it cannot establish that the device, Android release and CameraFi build will behave the same way under a longer unattended session.
Check CameraFi’s background-use controls
If the failure appears only after the phone locks, open Android Settings and look for CameraFi’s app-specific battery, power or background-activity controls. Depending on the phone, you may find these under Apps, App info, Battery, Battery usage or a manufacturer’s device-care menu. Labels and available options differ across Android releases and phone makers; use Settings search for “CameraFi” or “battery” if the menu structure is unfamiliar.
Some devices offer a choice that allows unrestricted battery use or background activity for an individual app. If yours does, note the current selection before changing it, then allow CameraFi the less restricted option for a controlled retest. Change one setting at a time and repeat the same timeout or manual-lock test. If the outcome does not change, restore the original choice rather than leaving a setting altered without evidence that it helps.
This is a diagnostic step, not an instruction that a particular option will work on every Android device. A manufacturer may use its own power-management layer, and Android permissions and service rules still apply. Changing battery optimisation cannot necessarily make an app continue a task that its implementation or the platform cannot carry out in the background.
Also check whether CameraFi has been force-stopped, whether you dismissed it from a recent-apps screen, or whether another power-saving mode is active. Keep those facts separate from the main test. Force-stopping an app is not the same as the screen timing out, and an aggressive whole-device power mode can add another variable. Record any such condition and test again with it unchanged before concluding that a per-app option mattered.
For a longer prerecorded sequence, a phone-based app may not be the right operating model if the screen must be off and nobody can monitor it. A continuous lofi stream scheduling workflow illustrates how scheduled playback differs from tapping through files on a phone. The useful question is not which approach is universally better, but whether you need live on-device interaction or unattended playback of prepared material.
What Doze can explain, and what it cannot
Android Doze is a power-saving state that may apply when a device is unplugged, stationary and screen-off. Android’s Doze and App Standby documentation explains that Doze restricts network access and defers CPU and network work. That makes screen-off operation worth testing, especially when the unplugged test differs from the charging test.
Doze is context, not a diagnosis. A screen going dark does not prove the device entered Doze, and a stream stopping during Doze does not prove Doze was the only cause. The source could pause, CameraFi could behave differently after losing foreground status, the network could fail, or the broadcast could have ended for another reason. Use the visible, timeout, lock and charging comparisons to narrow the possibilities rather than assigning blame based on timing alone.
Foreground services help Android apps perform ongoing work that is apparent to the user, but Android places restrictions on starting foreground services from the background. Camera and microphone work also have while-in-use permission requirements. See the Android Developers page on background foreground-service restrictions. These platform rules help explain why a battery preference cannot necessarily override every limit or make every capture task continue after locking.
The CameraFi materials reviewed for this issue describe supported source types and broadcast controls, but do not document the app’s specific service behaviour for a locked screen or promise screen-off playback. Nor do they document a guaranteed setting that fixes this symptom. Do not infer either universal support or universal failure from the absence of that detail. Treat each device and app version as something to test, and avoid relying on a change until your own controlled observations support it.
Decide whether to keep troubleshooting or change workflows
Use your observations to choose the next step. If CameraFi fails while visible, investigate the source and ordinary broadcast operation first. If timeout is fine but manual lock stops it, report that distinction. If unplugged operation fails but charging operation works, look more closely at power management while remembering that charging did not prove a single cause. If all conditions produce an ended broadcast, collect the details and ask CameraFi support rather than cycling through unrelated settings.
If your requirement is a live camera, screen share, or real-time interaction, CameraFi’s on-device workflow may be important. A hosted prerecorded-video loop is a different workflow: it can remove the need to keep your personal Android phone running the playback, but it does not reproduce CameraFi’s live camera or screen controls. For broader planning, our comparison of free and paid cloud services for 24/7 streaming can help you frame the trade-offs. Check any service’s current feature set and terms directly before relying on it.
StreamNeo can remove the specific burden of leaving your own computer running for an unattended prerecorded YouTube loop, but it is not a fix for CameraFi on Android and it does not replace a phone-based live camera or screen broadcast. Decide first whether you need to troubleshoot this on-device source or move to a hosted file-loop workflow. Keep the distinction clear when comparing options; they solve different operating problems.

FAQ
Will CameraFi Live keep playing if I turn off the Android screen?
Do not assume it will. The behaviour may depend on what you are broadcasting, the app and Android versions, and the phone’s power management; CameraFi’s public guide does not document a guaranteed screen-off playback fix. Test timeout and manual locking separately on your own setup.
Is battery optimisation the setting that fixes it?
It may be relevant if the problem occurs only after locking, so an app-specific battery or background-use setting is worth testing. Labels vary, and changing that setting cannot bypass every Android service or permission restriction. Treat the result as evidence about your device, not as a universal fix.
Why test while the phone is charging?
Android documents that connecting a charger exits Doze, so comparing plugged-in and unplugged behaviour can help narrow the cause. A difference points towards investigating power management; it does not prove Doze caused the interruption or that charging will keep CameraFi running reliably.
What should I send CameraFi support?
Include the CameraFi version, Android version, phone model, source type, network type and whether the phone was charging. Explain whether timeout, manual lock or both caused the symptom, and say whether the video paused, the app closed, the network dropped or the live broadcast ended.
