Frequently asked questions
What people ask most about version 2. If an answer has a demo, open it on the phone.
The basics
What's new in version 2?
Redesigned chats (themes, stickers, effects, polls, lists, countdowns and more), a new timeline with For you and Following, a new post composer, instant moments and calls with more controls.
In this guide every feature has its own demo: pick one and watch the phone.
Do I lose my chats when I update?
No. Your chats from the previous app move to the new one on their own in the background, and so do your moments and timelines. New photos and files are saved in the same folders as always.
Can I message someone who hasn't updated yet?
Yes. Messages, photos, videos, stickers, locations and calls work both ways with people still on the store app.
Some new features don't reach them: effects arrive as plain text, “View once” can't be sent to them and, if you change the chat theme, it only changes on your phone.
Why does it look a little different on Android?
On iPhone, the chat header and some bars have a glass effect. On Android those surfaces are solid and the conversation starts right below the header. The features are the same.
Chats
How do I reply to a specific message?
Swipe the bubble to the right, or hold it and tap Reply. In groups, the quote shows who you're replying to.
Is there a time limit to edit or delete?
No. You can edit your text messages and delete them for everyone whenever you want. Editing shows “edited”; deleting leaves “This message was removed”.
Why can't I see when my message was read?
The read time is in Message info, and only in 1:1 chats. If you turned off your read receipts, you can't see other people's either.
How many messages can I pin?
Up to 5 per chat, and they're pinned for everyone. When you pin a sixth, the oldest one is unpinned.
Can I search inside a chat?
Search is at the top of the chat list and looks through everything: chats, messages, photos and contacts. Tap a message and the chat opens right there.
Why doesn't Enter send the message?
Enter adds a line break, so you can write on several lines. The button on the right is the one that sends.
How do I add bold or a list?
Tap + › Format and use the bar that appears below the text field. You can also type *bold*, _italic_ or ~strikethrough~, and start a line with “- ” or “1. ” for a list.
Themes and effects
Does the other person see the theme I pick?
Yes: their wallpaper changes too and they see a notice that you changed the theme. If they still use the store app, the change stays on your phone only.
Why doesn't my chat make waves?
Waves start off. Turn them on in Customize › Waves and tap Apply. They're saved per chat and only on your phone.
Which phrases trigger effects?
“Happy birthday” sets off balloons; “congrats” and “congratulations”, confetti; “I love you” and “love you”, hearts; “happy new year”, fireworks. They also work in Spanish, Portuguese and French.
Why don't I see “View once”?
It only shows up in 1:1 chats, when the other person uses version 2 and the chat doesn't have disappearing messages turned on.
Privacy and security
Who can read my messages?
Only the people in the chat. Every chat has end-to-end encryption; the lock under the name is a reminder. Hold it to read what it means.
Do disappearing messages work in groups?
No, only in 1:1 chats. Choose 24 hours, 7 days, 90 days or “Once seen” in the contact info.
What happens if someone takes a screenshot?
In “Once seen”, the chat lets you know a screenshot was taken. While the screen is being recorded or shared, those messages aren't shown. On Android, photos that open once can't be captured.
What does “The security code changed” mean?
It usually happens when the other person reinstalls the app or changes phones. If you want to be sure, compare the safety numbers in their info in person.
How do I stop strangers from messaging me?
People you don't know don't go straight into your chats: they wait in “Message requests”, where you accept, ignore or block them. In Account Privacy you choose who can message you.
Photos, voice and files
Is there a size limit?
Documents can be up to 2 GB. A photo over 15 MB is reduced instead of rejected, and a video your phone can't convert is sent as a file.
How long can a voice or video note be?
A voice note lasts between 1 second and 5 minutes; when it reaches 5 minutes, it sends itself. A video note lasts up to 60 seconds.
Can I keep typing while a photo uploads?
Yes. You see the progress in the bubble and can keep sending messages. The × on the bubble stops the upload.
What is the “1” in the preview?
It makes the photo, video or voice note open only once. It can't be copied, forwarded, saved or pinned, and if nobody opens it, it's deleted after 14 days.
Timeline and moments
Why do I see posts from timelines I don't follow?
“For you” recommends posts based on what you're into; the more you interact, the better it gets. In “Following” you only see the timelines you follow.
Why does a photo look blurry?
It's sensitive content: it's covered with the reason, and you decide whether to see it with “See photo”. It stays visible until you close the app.
How many photos can I add to a post?
Up to 4 photos or videos. If you leave the composer, it asks whether you want to save the draft.
What's the difference between open, public and private?
Open: anyone can find it, see it and post. Public: anyone can see it, but you choose who posts. Private: only approved members see and post.
How do I stop seeing someone without unfollowing the timeline?
In the ⋮ menu of one of their posts, tap “Mute @username”. It lasts 30 days and you can turn it off sooner.
How long do moments last?
24 hours. They arrive instantly, and the colored ring on the photo tells you there's something you haven't seen.
Calls
How do I call someone back?
Tap the call in their chat, find it in Activities › Calls or, on iPhone, in the Phone app's Recents.
Where can I see how long a call lasted?
In Activities › Calls, tap the ⓘ on that call: you see what time it started, how long it lasted, when it ended and that it was encrypted.
Why does the audio come out of my headphones and not the phone?
Tap the audio button in the call: with headphones or Bluetooth connected, “Audio output” opens so you can choose. On Android you can use the earpiece even with headphones connected.
Activities
What does the number on the heart mean?
It's what you haven't seen yet in Activities. It clears when you open the tab; chat mentions and reactions are marked as seen when you open that chat.
How do I accept someone into my private timeline?
In Activities › Requests, tap Accept on their request. You can also reject it.
Can I delete an activity?
Yes: swipe the row to the left. In Calls, hold one to select several and delete them together, or tap Clear All.
Why don't I see all my calls in All?
All only shows missed calls. Incoming and outgoing calls are in the Calls chip.
Profile
How do I change my photo or my cover?
On your profile, tap the pencil, then the camera on your photo or “Change cover”. Choose Camera or Gallery, adjust it and tap Save changes.
Why can't I change my name?
On secure accounts, the first and last name can't be changed from the profile. The description and photo can.
Who can see my profile photo?
You choose: Only me, My Contacts, My Zone or Everyone. It's in Edit profile and in Settings › Account Privacy.
How do people add me in person?
Tap the QR at the top of your profile and let them scan it. You can also copy your link or share it through other apps.
How do I hide my posts from people I don't know?
Turn on Settings › Account Privacy › Private Profile. Others only see your name, photo and username.
How do I mute a chat without blocking it?
Tap the name at the top of the chat, then Mute: 8 hours, 1 week or Always. Nobody else sees that you muted it.
Settings and account
How do I turn on dark mode?
You › gear › Appearance, and choose System, Light mode or Dark mode.
Where do I back up my chats?
In You › gear › Backup. Tap Back Up or pick a frequency so it runs on its own. If you encrypt it, keep your PIN safe.
How do I make it so only my contacts can message me directly?
In Account Privacy › Messages, choose “Requested”. People who aren't your contacts stay in Message requests until you accept them.
How do I unblock someone?
Settings › Blocked contacts, tap Unblock and confirm.
What happens if I log out?
You can log out and keep your chats on the phone, or log out and clear the device data. Your account stays active on your other devices.
How do I delete my account?
Settings › Account › Dangerous area › Delete account. You have to type DELETE MY ACCOUNT to confirm; it can't be undone.
What is a Secure account?
It's an account with a verified identity: it has a green check and an identity score. If yours isn't one yet, “Get Secure” on your profile takes you through verification.
