Four apps commonly show their own incoming call experience on a Samsung S26 Ultra: WhatsApp, Telegram, Viber and Google Meet. In March 2026, a short demo video by the channel No Caller ID showed these app calls on the phone running One UI 8.5 over Android 16, each sounding different from the stock ringtone.
What the Samsung S26 Ultra incoming call demo shows
A Samsung S26 Ultra incoming call from WhatsApp, Telegram, Viber or Google Meet looks and sounds different from a normal phone call, because each app supplies its own call screen and ringtone under One UI 8.5. That is the core observation behind the video this article is based on.
The video, published on 2026-03-20 by the channel No Caller ID, is a short screen recording of a Galaxy S26 Ultra running One UI 8.5 over Android 16. It plays incoming calls from WhatsApp, Telegram, Viber and Google Meet back to back so the viewer can hear how each app's alert differs from the Samsung ringtone. The recording itself carries almost no narration, so the useful content is what appears on screen rather than what is said.
One honest caveat: the published transcript of the video contains only music and a single spoken word, so any detail in this article beyond what is visible in the video comes from Samsung's and the app makers' own documentation, not from the recording.
What One UI 8.5 and Android 16 mean on this phone
One UI is Samsung's interface layer on top of Android, and One UI is documented by Samsung as the software that shapes notifications, the call screen and system sounds on Galaxy devices. The S26 Ultra ships with One UI 8.5 running on Android 16, which is the pairing shown in the video's own tags.
Why this matters for calls: the base Android release defines how apps can present calling activity, and One UI adds Samsung's styling on top. When a video shows four different ringtones on one phone, the difference comes from the apps' own notification channels and call UIs, both of which pass through the One UI notification framework rather than bypassing it.
Keep version labels exact when comparing behavior. A setting described for One UI 6 or 7 may sit in a different menu in One UI 8.5, so older guides can send you to a screen that no longer exists in the same place.
Why WhatsApp, Telegram, Viber and Google Meet calls sound different
Internet-calling apps deliver incoming calls as their own high-priority notifications, not as cellular calls. WhatsApp, Telegram, Viber and Google Meet each bundle a ringtone and a full-screen call intent with that notification, so the sound you hear is the app's choice even though One UI renders the screen.
In practice this means three things on a Galaxy phone:
- The ringtone is set inside the app, not in Samsung's Sounds and vibration menu.
- The call screen is the app's design, scaled to the phone's display.
- If the app's notifications are muted or restricted by battery settings, incoming calls can arrive silently even when the system volume is up.
Cellular calls behave differently: they go through Samsung's own Phone app, so they use the system ringtone, which on 2026 Galaxy flagships is the current Over the Horizon arrangement.
Where each app sets its own incoming call sound
Each of the four apps in the video keeps its ringtone setting in a different place. The table below maps the app to the menu where its call alert is configured, so you can match the sounds heard on the S26 Ultra to your own device.
| App | Where the call ringtone is set | Call type |
|---|---|---|
| Settings > Notifications > Calls | Internet call | |
| Telegram | Settings > Notifications and Sounds > Calls | Internet call |
| Viber | Settings > Notifications and Sounds > Calls | Internet call |
| Google Meet | Notification categories in Android settings | Internet meeting invite/ring |
| Samsung Phone app | Settings > Sounds and vibration > Ringtone | Cellular call |
If a change does not seem to take effect, check Android's per-app notification categories as well. One UI 8.5 exposes those categories under each app's notification settings, and a disabled call category overrides the in-app ringtone choice.
Fixing silent or misrouted incoming calls on One UI 8.5
Silent incoming calls from these apps usually trace back to three settings rather than a hardware fault. Work through them in this order before assuming the phone is broken:
- Open the app's own notification settings and confirm the Calls category is on and has a sound assigned.
- In One UI settings, open the app's battery profile and remove restrictions such as Put app to sleep, which can delay or drop the full-screen call notification.
- Check Do not disturb: One UI lets you exempt specific apps, so add your calling apps if you want their calls to ring through.
If the phone rings but shows the wrong screen, force-stop the calling app once. On Samsung builds a stale app process occasionally keeps the old notification UI alive after an update, and a restart reloads the current call screen.
Frequently asked questions
- Do WhatsApp calls use the Samsung ringtone on a Galaxy S26 Ultra? No. WhatsApp calls use WhatsApp's own call ringtone and call screen. Only calls through Samsung's Phone app use the system ringtone.
- Can I set one ringtone for all internet calls in One UI 8.5? Not from the Samsung settings alone. Each app sets its own call sound, so you configure WhatsApp, Telegram, Viber and Google Meet separately inside their settings.
- Does One UI 8.5 change how incoming calls look? It styles the system call screen and notification framework, and apps building on Android 16 notification and calling APIs inherit that framework. The in-app call designs themselves still come from each app.
- Why does a Google Meet call ring differently from a phone call? Meet announces an incoming meeting through its own notification with its own sound. It is an internet meeting ring, not the cellular ringtone.
Turn your own phone walkthroughs into written guides
This article exists because a three-minute screen recording of call ringtones contains knowledge that search works better in text: menus, settings names and a comparison table. The same is true of most phone tips, app walkthroughs and setup videos creators publish.
If you have explanations like that sitting in your own YouTube uploads, Skala Blog turns a video URL into a structured written article: paste the link, the video is transcribed, and you get an editable draft. It is a straightforward way to give the same guidance a searchable, skimmable form.
