An unlocked phone was enough to read the 24-word recovery phrase. The
phrase, backup export and import, the duress PIN, a longer auto-lock,
turning off screen security, enabling biometrics and deleting the
account now ask for the PIN (or biometrics with biometricOnly) every
time. The duress session never shows the phrase. PIN checks outside the
lock screen count towards the same failure throttle.
A new look across the app and a set of everyday messaging features.
Interface
- Home screen with Chats, Contacts and Settings tabs, a large title,
search across chats and message text (diacritics-insensitive), filters
and pinned chats.
- Conversation view with a translucent header and composer, grouped
bubbles, author avatars and colours in groups, swipe to reply, an
"N new messages" marker, a jump-to-latest button and in-chat search.
- Contact and group profiles: verification, shared photos, groups in
common, disappearing messages, mute, block; members, admin badges,
adding people, rename and leave for groups.
- Full-screen photo viewer that pages through the whole conversation.
- A stable avatar colour per person and a clearly visible read state.
Messaging
- Polls in chats and groups, single or multiple choice, with votes that
can be changed or withdrawn; older clients see them as text.
- Drafts survive leaving a chat and show in the chat list.
- Forwarding of messages, photos, files and voice messages.
- Notes to self: a local-only, encrypted chat that never reaches the
relay.
- @mentions in groups that notify even when the group is muted.
- Typing indicators sent as ephemeral messages, opt-in and mutual like
read receipts.
- Delivery and read times per message and per group member.
- Profile photos, cropped, resized and stripped of metadata, delivered
encrypted to contacts.
- Voice message playback at 1.5x and 2x.
- Call buttons in 1:1 chats and call log entries.
Fixes
- Muted groups no longer notify: muting was checked against the
author's chat instead of the group.
- A blocked contact could unblock itself by changing its delivery
address.
- Read receipts no longer regress to delivered when a late delivery
receipt arrives.
- A message marked as failed corrects itself once it is delivered.
- Double ticks in groups now mean delivered to every member.
Registration failures from the distributor were swallowed, so push looked
enabled while nothing arrived. Without wake-ups Android suspends the app
and messages only show up once the user opens it — which looks like broken
delivery even though the relay has them queued.
The failure is now remembered and surfaced in Settings, and the chat list
carries a dismissible line explaining the state.
Settings crashed with a TypeError: the profile card passed a
SepotFingerprint object where the localized string formatter expects
a String (hidden behind a `dynamic` parameter). Also fixes RangeError
in avatar initials (empty names, double spaces) and switches initials
to grapheme clusters so emoji don't get split.
New photo preview screen: a captured or picked photo no longer sends
immediately — it opens in a preview with freehand drawing (7 colours,
undo), draggable text overlay, 90° rotation and a caption field.
Nothing leaves the device until Send is tapped.
Incoming-content hardening: decryption and content processing are now
separated in the delivery path. Once an envelope is decrypted the
ratchet has advanced, so redelivery can never help — permanently
malformed content (FormatException/TypeError) is acked and dropped
instead of poisoning the queue on every reconnect. Attachment metadata
now validates base64 of the crypto fields up front, and a corrupt
inline thumbnail no longer breaks bubble rendering.
PNG without real transparency (screenshots, edited photos) is now
re-encoded as JPEG — several times smaller on the wire.
Tests: 116 (new widget tests for Settings and the photo preview,
AttachmentMeta wire validation).
