Updated August 2026 · Every step, switch name and save location below is quoted from Google's or Samsung's own support page, read on 19 August 2026 · the audio options differ by maker more than most guides admit
The built-in recorder is all most people need because Google's own page, read 19 August 2026, documents starting it from a Quick Settings tile with no app and no root. Set the audio before you start because Google exposes two separate switches, Record device audio and Record microphone, and Samsung offers three named values instead. A black clip is not fixable because Android's own FLAG_SECURE prevents a marked window "from appearing in screenshots". Data checked: 19 August 2026.
Every current Android phone records its own screen without an extra app, and the tool is two swipes away. Two things decide whether the clip is usable: the audio source, which you must set before you start, and whether the app you are recording has told Android not to be captured. The table puts the Pixel and Galaxy wording side by side, because they are not the same and most guides print only one.
Getting going
Both makers document the same opening move, and both note that the tile may need adding first.
On a Pixel, Google's own page reads: "Swipe down twice from the top of your screen. Tap Screen record. If it's not there, swipe right or tap Edit. Touch and hold, then drag Screen record to your Quick Settings." Then: "To start a recording, tap Start. The recording begins after the countdown." Google adds that "Before you start, you can choose whether to record audio, a single app or your entire screen", and to stop you "swipe down from the top of the screen and tap the Screen recorder notification".
Recording a single app is a Pixel feature Samsung does not document, and it is the one worth knowing if you are filing a bug report or showing something to a relative: nothing outside that app, including your notifications, reaches the video. Google's steps are "When prompted, tap A single app" then "Start recording", then pick the app from the selector.
Your face in the corner is documented on both, differently. Google: turn on "Record device audio, Record microphone, and Show selfie camera", with one limit stated plainly, that "This feature doesn't support front camera zoom". Samsung exposes a "Selfie video size" setting instead and notes it "is only available with devices that support the front camera when recording the screen".
On a Galaxy, the settings live behind a long press rather than a menu. Samsung's own article, dated 21 December 2025: "Open the Quick settings panel by swiping down from the top right of the screen. Then, touch and hold the Screen recorder icon to open its settings page." That page is where video quality lives, which Samsung documents as "High (1080p), Medium (720p), and Low (480p)", and where you find "Show taps and touches", described as "Small dots will appear whenever you touch or tap the screen while recording". For a how-to clip that one is worth turning on so a viewer can follow your finger.
Samsung attaches a caveat to the whole page that is worth carrying: "Availability of some settings will vary based on the model and software version."
The audio choice
This is where recordings come out silent, and the reason is that the two makers do not offer the same thing.
Google gives you switches. On a Pixel the audio choice is two independent toggles, named in Google's own instructions as Record device audio and Record microphone. Device audio alone gives a clean app or gameplay clip with no room noise. Both together give you commentary over app sound, which is what a tutorial needs. Microphone alone gives narration over a silent screen.
Samsung gives you three named values. Its settings page lists one setting, Record sound, and Samsung writes that "You can choose from None, Media, or Media and mic."
Read those two lists against each other, because a guide that prints only one will mislead you. There is no microphone-only value among the three Samsung documents. On a Pixel you can record your voice with the app muted; on a Galaxy, by Samsung's own list, the choice is silence, media, or media plus your voice. If you came here to narrate over a muted app on a Galaxy, that is the thing to check on your own device before you plan a recording around it.
Whichever phone you have, set the source before you start. There is no supported way to change it mid-recording, and a silent clip almost always means the source was left on none or on microphone with nothing being said. The microphone also picks up the room, so a fan or a television in the background is baked into the file.
The hard limit
A recording that plays normally and then turns into a black rectangle is not a fault, and no setting turns it off. It is a flag the app set, and Android's own documentation names it.
The Android reference for window flags describes FLAG_SECURE in one sentence: "Window flag: treat the content of the window as secure, preventing it from appearing in screenshots or from being viewed on non-secure displays." An app that sets it is telling the system that its window must not be captured, and the system obeys, which is why the frames come back black and the audio often goes with them.
That is why it behaves the same way with the built-in recorder and with every recorder from the store: the block sits below the app doing the recording, not inside it. Streaming apps are the obvious case; banking and wallet apps commonly set it on the screens showing balances and card numbers. A recorder that claims to defeat it is claiming to defeat a platform flag, which is a good reason to be suspicious of it.
A silent clip is a different problem and usually is fixable. Work through it in order: check the audio source is not set to none or microphone only, check the phone is not on silent or very low volume, and test with something simple for a few seconds before recording the thing you actually care about. If every recording in every app comes out black and silent, that is not this flag, and a restart clears it more often than it has any right to.
One thing worth saying out loud: if the plan is to keep a copy of a paid film, this is a dead end technically and a legal problem separately. For a tutorial, a bug report, a gameplay clip or a how-to for a relative, none of this gets in your way.
Finding the file
Where the file lands is documented on both platforms, and neither is quite the folder people expect.
On a Pixel, Google gives the route rather than a folder name: "Open the Photos app. At the bottom, tap Collections" then "On this device" then "Movies".
On a Galaxy, it is a setting rather than a fixed location. Samsung lists "Save screen recordings in: Select where your screen recordings will save", with the note that "This option may not be available on all devices". So on a Galaxy, check that setting before you go hunting.
Trimming is worth doing before you share, mostly to cut the few seconds at the end where you were reaching for the stop button. Open the clip in Photos, use the edit control, drag the handles at each end of the timeline inward, and save a copy so the original survives.
Size is the practical constraint. Google flags it on the same page: "Video files can be too large to share over some services. You can share a link through the Photos app instead." A few minutes at 1080p runs to hundreds of megabytes, which some chat apps refuse outright and others compress into mush. On a Galaxy, dropping the quality setting to Medium before you record is easier than fixing it afterwards.
Going further
For most people the built-in recorder is the whole answer, and it has one advantage no store app can match: it is already there and it is not asking for anything.
A separate recorder earns its place in narrow cases: a webcam overlay your phone does not offer, drawing on the screen while recording, or longer captures with editing built in. Two things to keep in mind before you install one. No third-party recorder gets around FLAG_SECURE, so none of them will record a protected app, whatever the listing implies. And a screen recorder sees your entire display by definition, which makes it a category where the permissions it asks for and the reviews it has matter more than usual.
If what you actually want is the audio rather than the video, that is a different tool: our roundup of voice recorder apps for Android covers recording sound properly, and our guide to transcribing a voice recording on Android covers turning it into text. If the screen itself is the problem rather than the recording, screen mirroring to a TV is the neighbouring guide.
Open Quick Settings with two swipes down and tap the Screen record tile. On a Pixel, turn on Record device audio and leave Record microphone off. On a Galaxy, open the recorder settings by touching and holding the tile, and set Record sound to Media. No extra app and no root are needed on either. Checked 19 August 2026.
On a Pixel yes, because Google exposes the two as separate switches: turn Record microphone on and Record device audio off. On a Galaxy, Samsung's own settings page lists three values for Record sound, "None, Media, or Media and mic", and none of them is microphone only. Check your own device before planning a recording around it. Checked 19 August 2026.
Because the app told Android not to allow it. Android's own documentation describes the FLAG_SECURE window flag as one that treats a window's content as secure, "preventing it from appearing in screenshots or from being viewed on non-secure displays". The system enforces it below the recorder, so it happens with the built-in tool and with every app from the store, and no setting turns it off. Checked 19 August 2026.
Almost always the audio source. Check it is not set to none, and not set to microphone with nothing being said, then check the phone is not silenced or turned right down. You cannot change the source once recording has started, so test a few seconds with something simple before recording the thing that matters. Checked 19 August 2026.
On a Pixel, Google's route is the Photos app, then Collections, then On this device, then Movies. On a Galaxy it is wherever the "Save screen recordings in" setting points, and Samsung notes that option is not available on every device. Checked 19 August 2026.
On a Pixel, yes, and it is documented: when prompted, tap "A single app", tap Start recording, then choose the app. Everything outside it, including anything that arrives in your notification shade, stays out of the video. Samsung does not document an equivalent on its screen recorder page. Checked 19 August 2026.
No, and for most purposes there is no reason to. A store app earns its place only for a webcam overlay, on-screen drawing or built-in editing that your phone does not offer. None of them can record a protected app, because FLAG_SECURE is enforced by the system rather than by the recorder, and a recorder sees your whole display, so its permissions deserve a look. Checked 19 August 2026.
Checked 19 August 2026: this page described both menu paths from memory and linked neither maker, so every step is now quoted from Google's Pixel Phone Help page or Samsung's own support article, the latter carrying its own date of 21 December 2025. The corrections that change what a reader does: the Pixel audio choice was described as a menu of three options, where Google documents two independent switches, Record device audio and Record microphone; and microphone-only was presented as a universal option, where Samsung's own settings page lists exactly three values, "None, Media, or Media and mic", with no microphone-only among them, so a Galaxy owner planning to narrate over a muted app was being told something Samsung does not document. The save locations were both wrong in detail: Google publishes a route through Photos, Collections, On this device, Movies, rather than a bare Movies folder, and Samsung documents a "Save screen recordings in" setting rather than a fixed Gallery folder, adding that the option "may not be available on all devices". The explanation for black recordings was asserted rather than sourced and is now quoted from Android's own reference for FLAG_SECURE, which prevents a window "from appearing in screenshots or from being viewed on non-secure displays". A claim that the Samsung recorder moved to Quick Settings with One UI 2 on Android 10 is supported by no Samsung page that can be read and has been removed. Samsung's own caveat that availability varies by model and software version is now on the page, as is Google's note that the selfie feature does not support front camera zoom. A decision table, an "Our answer" capsule, a dated verification box and this changelog are new.
