If your Streamlabs Mobile YouTube stream stops as soon as the screen locks, keep the phone unlocked for the whole broadcast. Streamlabs’ mobile-game streaming guide says the stream will end if the device locks; the supported fix is to prevent the lock, not to look for a setting that promises screen sharing will continue while locked.
If the stream still ends while the display remains awake, treat that as a separate fault to investigate. Screen capture, interruptions, app load, and connection trouble are not interchangeable explanations, and the available guidance does not confirm one cause for every phone or stream type.
The quick fix: keep the phone unlocked
Streamlabs’ instruction is direct: “Stay unlocked while live: If your device locks, the stream will end.” In other words, when you are broadcasting a phone screen through Streamlabs Mobile, leave the display awake. You can read the full advice in the Streamlabs mobile-game streaming guide.
This matters most when the broadcast is built around screen capture: a game, an app demonstration, a set of slides, or another view of the phone itself. Locking the phone is not a reliable way to save battery while keeping that capture live. There is no documented Streamlabs Mobile setting in the material reviewed that guarantees screen sharing will survive a lock, so do not assume that changing a toggle will override the advice.
For a short live session, keeping the phone awake may be manageable if you can safely leave it in a stable place and monitor it. For a long devotional set or a stream that should run unattended, a phone-based screen share may not suit the job: the device still needs to remain awake and the broadcast needs attention. Planning the workflow around that limitation is more useful than repeatedly trying the same locked-screen test.
Check whether the lock coincided with the end
Start by matching the stop time to what happened on the phone. Did the display go dark or show the lock screen just before the stream ended? If so, the timing fits the failure Streamlabs describes. Note whether you pressed the side button, allowed the normal screen timeout, or saw the phone lock after leaving it alone. You do not need to diagnose the operating system; the practical question is whether the screen was still awake when the broadcast stopped.
For the next brief test, keep the screen visible and awake throughout. If the stream stays live, that is useful evidence that the lock was involved, though it does not prove every detail of the app’s behaviour. If it stops while the screen remains awake, record the time and what was on screen, then check the other possibilities below rather than treating every stop as a lock failure.
Distinguish a stopped broadcast from a viewing problem, too. If you can, check the live from another device or ask someone watching to confirm whether it ended. A viewer who cannot load the picture may be seeing a playback or connection issue even if the broadcaster’s app is still open. Conversely, an app that has returned to its setup screen may indicate that the broadcast itself ended. These observations help narrow the next test; they are not a substitute for Streamlabs’ lock guidance.
Why screen capture may leave the app suspended
Streamlabs’ mobile FAQ explains that screen capture puts its app in the background, where it is effectively suspended. It also says that on iOS it disables widgets during screen broadcasting to reduce the risk that the operating system kills the app. The Streamlabs Mobile Streaming FAQ gives useful context, but it is not a device-by-device diagnosis of every stop.
The careful conclusion is that screen capture changes how the app runs, and a lock can coincide with the broadcast ending. Do not turn that into a claim that every phone suspends every kind of stream in exactly the same way. A camera stream, a screen share, and a stream where the app is merely left in the background are not necessarily the same situation. The reviewed guidance does not establish a lock-survival setting or a universal lifecycle explanation.
That distinction also helps you avoid unproductive fixes. Network Boost, for example, is described by Streamlabs as using multiple internet connections to support connection reliability. It addresses a different concern from the phone locking; Streamlabs does not describe it as keeping screen capture alive after the display locks. Check the Network Boost explanation if connection reliability is your concern, but do not treat it as a lock remedy.
Keep the display awake while you broadcast
Before going live, check the phone’s own display timeout and set it so the screen will not lock during the planned test. The exact menu name and available choices depend on the device and software version; the sources reviewed do not specify a universal path. Use the device’s current display settings rather than following instructions for a different model, and restore your usual timeout afterwards if you prefer it.
Make the phone usable while awake. Put it on a secure stand, keep the charging cable clear of the controls, and frame the screen so you can notice if Streamlabs leaves the live view. These are practical ways to monitor the broadcast, not technical fixes for lock behaviour. Keep the device in a ventilated place and avoid covering it; a long, bright session can be demanding, but buying a case, charger, or cooler is not a documented solution to this particular failure.
If you need to move away, arrange a person to check the phone or choose a workflow that does not depend on an unattended, unlocked mobile screen. Do Not Disturb can reduce notification interruptions, and closing other apps may reduce lag or crashes, according to Streamlabs’ general mobile guidance. They are sensible hygiene steps, not guaranteed repairs for a stream that ends on locking. Do not mistake a quieter notification screen for permission to lock the phone.
iOS screen-broadcast considerations
On iOS, Streamlabs says it disables widgets during screen broadcasting to reduce the risk of the operating system killing the app. That detail reinforces the need to keep the workflow simple while a screen broadcast is running. It does not mean that a particular iPhone display setting or Streamlabs control can guarantee an ongoing broadcast after the device locks.
Keep the test focused: begin the screen broadcast, leave the device unlocked, and observe whether it stays live. Avoid switching repeatedly between apps or adding steps that make it hard to tell what happened. If it stops while still awake, note whether you received an alert, the app closed, or the YouTube live ended. Those details can help when checking current Streamlabs support guidance, without assuming an iOS setting is the cause.
Do not transfer an iPhone-specific explanation to Android, or the reverse. Android manufacturers can present display and battery controls differently, while the cited Streamlabs guidance does not list model-specific settings. For either platform, the robust advice from the mobile-game guide remains the same: leave the device unlocked during the Streamlabs Mobile screen-share broadcast.
Separate lock trouble from other causes
If you have confirmed that the phone remained awake, make one change at a time. Close other apps before the next test, as Streamlabs recommends this to reduce lag or crashes. You can also enable Do Not Disturb to reduce interruptions. Test each change separately if practical; otherwise, if the stream stabilises, you will not know which condition mattered. Neither step is documented as a cure for a lock-triggered stop.
Check the connection only when the symptoms point that way. A stream that degrades or drops while the screen is still lit is a different pattern from one that ends at the moment the phone locks. A stronger or more consistent connection may matter to the first pattern, but it cannot keep a locked screen capture active according to the guidance at hand. Avoid paying for a feature or changing networks solely to solve a lock-timing symptom.
YouTube’s mobile eligibility rules are separate again. YouTube Help says mobile live streaming requires a verified channel, live streaming enabled, no live-streaming restriction in the previous 90 days, at least 50 subscribers, and a compatible device; first-time activation can take up to 24 hours. See YouTube’s mobile live-streaming requirements for the current rules. Eligibility can stop you from starting a mobile live, but it does not explain a broadcast ending exactly when the screen locks.
Test the setup before a longer session
Run a short private or otherwise low-stakes test before planning a long broadcast. Start with the phone’s display timeout set to stay awake, begin the screen capture, and leave the device untouched long enough to observe the live. Confirm from another device if possible that the live remains visible. Then note the screen state, app state, and approximate time if anything stops. This gives you a useful baseline without claiming a test can guarantee a later session.
If the awake-screen test succeeds but you need the phone locked, do not treat that as solved. The material reviewed provides no Streamlabs Mobile configuration verified to keep screen sharing alive after lock. You may investigate a different broadcasting workflow, but it will involve a different setup rather than a proven fix for this app behaviour.
YouTube documents mobile, webcam, encoder, and console as distinct ways to go live in its overview of live-streaming options. A computer-based encoder may fit a channel that needs to run without an unlocked phone, but the cited material does not validate a particular encoder setup as a remedy for this Streamlabs Mobile symptom. For a loop built from a prepared video, a separate 24/7 Punjabi bhangra stream workflow may be more relevant than screen sharing a phone. If your source is a recorded study session, see the guide to a 24/7 Pomodoro stream from recordings. These are different channel workflows, not settings to apply to the mobile app.
For a prolonged prerecorded broadcast, being able to switch off your own computer may remove the need to keep a phone awake and watched. StreamNeo turns an uploaded video into a YouTube live stream, so the specific burden it removes is maintaining an unlocked mobile screen for that prepared-video use case; it is not a Streamlabs lock-setting and it is YouTube-only. If you are weighing that route against doing the broadcast yourself, the always-on channel operating options explain the decision in terms of how the channel runs. A YouTube podcast stream on JioFiber is another useful read if your actual issue is connection drops rather than a screen lock.

FAQ
Can Streamlabs Mobile keep streaming after I lock my phone?
Streamlabs’ mobile-game guide says the stream will end if the device locks, so keep it unlocked during the broadcast. The sources reviewed do not document a setting that guarantees screen capture continues after locking.
Why does it stop as soon as the screen locks?
The timing is consistent with Streamlabs’ warning, and its FAQ says screen capture leaves the app effectively suspended in the background. That is useful context, not confirmation of one identical operating-system cause on every device or stream type.
Will Do Not Disturb or Network Boost fix it?
Do Not Disturb may reduce notification interruptions, and closing other apps may help with general lag or crashes; Streamlabs does not present either as a lock fix. Network Boost concerns connection reliability, not keeping the display awake or screen sharing alive after a lock.
What if the live stops while the screen is still awake?
Treat that as a separate issue: test with other apps closed, reduce interruptions, and check whether the app or the broadcast ended. YouTube mobile eligibility affects whether you can start a stream; it is not an explanation for a live ending precisely when the phone locks.
