Why is your recorded LINE call always silent on playback?
This is probably the most common reader email we receive.
Most people try to record a LINE call by instinctively opening iPhone's screen recording, only to find the entire video silent—just their own voice, with none of the other person's speech captured.
The problem isn't your operation; it's how LINE works. LINE calls use VoIP, with audio processed within the app on both ends, and the official app offers no recording or export function. So-called "call recording" apps on the market almost always fail on iPhone—iOS doesn't allow third-party apps to access the audio stream during VoIP calls.
Another common approach is to use a second phone to record nearby. This does work, but audio quality depends on speaker volume and ambient noise, making it hard to listen back clearly.
A more reasonable approach is to handle it at the system level: iPhone added "Native Capture" starting with iOS 26, while Android has built-in screen recording. Below, we break down the actual steps for both systems.
Before you start, confirm these 3 things
1. Is your system version new enough? iPhone's "Native Capture" is a system feature available only in iOS 26; older versions won't have it. Android devices mainly rely on built-in screen recording, with slight path differences across brands.
2. Legal boundaries of recording In Taiwan, if you are a party to the call and record for evidence preservation or work documentation, it is generally legal; however, recording to pry into others' privacy is not. In practice, the safer approach is to inform the other party before recording.
3. Do you need an audio file or text? If your real need is to organize meeting notes and extract action items afterward, you don't necessarily need a perfect audio file—converting the recording to a transcript is usually more efficient than repeatedly listening.
Recording LINE calls on iPhone in 2026: 5 steps
Step 1: Update your iPhone to iOS 26
Go to Settings → General → Software Update and confirm your system is up to date. "Native Capture" was added in iOS 26; if your version is older, it won't appear in Control Center.
Step 2: Add "Native Capture" to Control Center
Open Settings → Control Center, find "Native Capture" in the available items, and add it. Once added, you can start it with one tap from Control Center during a call.
Step 3: Start a LINE call and turn on speakerphone
Many people miss this step. Current tests indicate that you need to turn on speakerphone first so the system can capture both audio tracks; without speakerphone, the other person's voice is often not captured at all.
Step 4: Pull down Control Center, tap "Native Capture," and select "Audio Only"
During the call, pull down Control Center, tap "Native Capture," and set the recording type to "Audio Only." The option name may vary slightly by iOS version; just look for the one that records sound only.
Step 5: Stop recording after the call and confirm the file is saved
Stop recording before hanging up, then exit and check the storage location to confirm the file exists. Also, try not to let the screen go idle for long periods during recording, to prevent the system from interrupting the process to save power.
An honest reminder
Regarding the actual recording quality of "Native Capture," online test results are inconsistent: some say both sides are clear, while others report their own voice is clear but the other party is quiet or muffled. This may depend on the device model, speaker volume, and ambient noise.
We recommend doing a 30-second test recording with a friend before using it for important content. Confirm the quality is acceptable first.
What about Android and desktop?
Android: Most models can use built-in screen recording. The key is to enter the recording settings before recording and enable both "Microphone" and "System Audio/Media Audio" sources; otherwise, you'll only capture one side.
Desktop LINE: If the call is on your computer, using a desktop tool that can record system audio is more convenient than a phone, especially for long online meetings.
External recording devices: For older iPhones or situations requiring stable audio quality, external voice recorders or AI recording hardware remain reliable options, at the cost of carrying an extra device.
The real work starts after recording: turning audio into transcripts and action items
Honestly, getting the audio file is only half the job. The real time sink is re-listening to that 40-minute call and taking notes manually.
This is why I usually recommend using a tool. Tinrec is an AI meeting notes and collaboration tool for individuals and teams, available on iOS, Android, and web. It can't record LINE calls for you—but importing your recorded audio is where it shines.
Stop organizing recordings by hand
Upload audio or video and automatically get a transcript, summary, and action items
The typical workflow: after the call, upload the audio file, and Tinrec converts it to a transcript while automatically generating summaries, chapters, and action items. Who promised what and when it's due—no need to dig through it yourself.
Even better is AI Q&A. After recording, you can directly ask "What was the budget cap the client mentioned?" or "What unresolved issues were discussed?" and it answers based on the content, rather than dumping a list of keywords for you to search. This is the main difference from pure transcription tools.
If the call is with a foreign client, Tinrec also supports real-time translation and bilingual display, so you can view the original and translation side by side during the meeting. Organized results can be exported directly to Notion, Google Docs, and other tools, or further generated into reports, tables, and meeting minutes.
Note that file imports consume plan quota. The free version provides basic quota to experience recording, importing, summaries, and transcription; if you have steady weekly needs, the Pro plan is more suitable; for long-term accumulation of recording data, the annual plan offers a lower monthly cost. For team use, there are separate team spaces with member, role, seat management, usage analytics, and audit logs.
In one sentence: if you only record occasionally, the built-in system feature is enough; if you want to quickly get transcripts and action items after recording, a post-meeting tool like Tinrec is worth trying.
Besides Tinrec, what other options are there?
Otter.ai: A mature choice for English meetings, with a generous free tier of 300 minutes per month. However, its design focuses on English business meetings, and it struggles with mixed Chinese-English content; Tinrec has specific designs for mixed Chinese-English content and team hotwords.
Notta: Positioned similarly to Tinrec, with a free tier of 120 minutes per month and a 3-minute limit per recording, and Pro annual billing at about USD 8.17/month. Transcription and translation are good, but it lacks Tinrec's desktop method of recording online meetings directly from system audio without inviting a bot.
PLAUD Note / NotePin: Hardware representatives; NotePin costs USD 159 and Note Pro USD 189, suitable for frequent travelers who need portable recording. The trade-off is carrying an extra device; if your main need is online meetings and organizing existing audio files, a pure software solution like Tinrec is more convenient.
Pitfall guide: 4 most common mistakes when recording LINE calls
Mistake 1: Assuming screen recording captures both sides automatically iPhone's screen recording only captures the microphone by default—your own voice. To record LINE calls, you need a system-level feature like "Native Capture," not screen recording.
Mistake 2: Forgetting to turn on speakerphone This is the most common failure reason. Without speakerphone, the other person's voice is often not captured at all, leaving you with a blank audio track.
Mistake 3: Switching to another app or letting the screen idle mid-recording Switching to an app that requires the microphone (e.g., another recording app) during recording may cause interruption; long screen idle time may also cause the system to stop the process to save power. Stay on the call screen throughout.
Mistake 4: Leaving the recording unbacked up and untranscribed Recordings left for a long time become forgotten and hard to search. Back up the file the same day and convert it to a transcript so you can find specific quotes later.
One non-technical pitfall: Not informing the other party before recording. Beyond legal risks, the more realistic issue is trust. Under Taiwan regulations, party recording is generally feasible, but proactively mentioning it makes future interactions much easier.
Conclusion: Which method should you use?
- Using iPhone with iOS 26 → Built-in "Native Capture," free, no external device needed
- Using Android → Built-in screen recording, remember to enable both microphone and system audio
- Older phone or need stable audio quality → External voice recorder or AI recording hardware
- Need transcripts, summaries, and action items after recording → Import audio to Tinrec to save re-listening time
- Team needs to share meeting notes → Tinrec team version has separate spaces, seats, and permission management
FAQ
Q1: Will the other party be notified when I record a LINE call on iPhone? According to current tutorials and test reports, iOS 26's "Native Capture" is system-level recording, and the other party will not receive a recording notification. However, "not being notified" and "not needing to inform" are two different things; we still recommend proactively explaining.
Q2: Why do I only hear my own voice in the recording? Two most common reasons: one, speakerphone was not turned on; two, screen recording was used instead of "Native Capture." Check these two first, then check the audio source settings in Control Center.
Q3: Will LINE release a recording feature in the future? Currently, LINE does not offer call recording or export functions, citing communication privacy protection. In the short term, system-level methods are likely still necessary.
Q4: Can I switch to other apps while recording? Yes, but switching to an app that requires the microphone may interrupt recording. We recommend staying on the same screen during the call and recording, and avoiding long screen idle time.
Q5: Can the recorded audio be converted to a transcript? Yes. Tinrec supports importing audio and video files for transcription and automatically generates summaries, chapters, and action items; imports consume plan quota, and the free version offers basic quota to try.
Q6: Are free tools enough? If you only record occasionally and listen yourself, built-in system features are completely sufficient. If you need transcripts, AI Q&A, and team sharing, consider professional tools with free tiers—run a few tests with the free version before deciding whether to pay.
