Known Issues
Issues Affecting All Platforms
- For this release all QtMobility library names have a _tp suffix
- Messaging filtering and Sorting functions are not fully optimized.
- Versit support for Contacts API is ALPHA, see src/versit/README
- Not all example applications will display(fit) well on small screens.
Symbian/S60 Specific
Bearer Management
No specific issues to highlight.
Contacts API
- Async contact operations not supported
- Support for SIM contacts is not supported
- Extending contact fields at runtime is not supported on most Symbian platforms because would compromise compatibility with the S60 platform Phonebook application.
- auto test failures for tst_qcontactasync and tst_qcontactmanager
- samplephonebook not operating properly due to backend problems
Location API
No specific issues to highlight.
Messaging API
- Exporting IMAP or POP3 Message Updates from client to server is not supported
- Only one level of folders is supported <=> Symbian/S60 applications do not use nested folders
- Complex filter cases are not supported where nested filters are used (for example: QMessageFilter::byParentAccountId(const QMessageAccountFilter ,...)
- ReceptionTimeStamp is not supported in filtering <=> Symbian reports only one date for SMS & MMS which means that QMessage::date() field is used, not receivedDate())
- Message size reporting should be improved
- Preferred charsets handling auto test cases do not pass
- Cc address handling does not pass all auto test cases
- Multipart message body/attachment content type handling does not pass all auto test cases (problems with .png content)
- replyToAll functionality does not pass "to" & "cc" field auto test
- Local services messages, for example bluetooth, are listed/read in Inbox
Multimedia API
- Playback of streaming or DRM protected media not supported
- S60 specific play list not supported
- Camera related functionality not supported (take picture or record video from camera)
- Radio related functionality not supported
- Device specific play list management not supported.
- Trans coding of media not supported
- Media editing not supported
- TV not supported
- Audio capture does not support currently any special features like format, encoding etc...
- No S60 specific auto test cases exists
- mute sometime disables audio output in mediaplayer
- seeking is not working properly
- video size does not remain constant in repeated plays
- full screen video not working OK
- player example application sometimes freezes
Publish and Subscribe API
- Remove value from RProperty/CRepository not supported
- Mapper service running in its separate process (Symbian OS server) not supported
- Not all the types are supported by RProperty and CRepository.
- Autotests do not work. (Need support of removing values as well as S60 specific CRML files.)
Service Framework API
Several failing autotests.
System Info API
- Battery status incorrect on test applications startup
- Phone is still charging but power state shows 100% and "wall power"
Maemo Specific
- Messaging backend for Maemo is not yet implemented.
- The Publish and Subscribe API only supports subscription but not publification.
- Location backend for Maemo is not yet implemented.
Windows Mobile Specific
Contacts API
The samplephonebook application has the following limitations
- Adding a Contact Group fails.
- Adding an Avatar to a contact fails.
- Not all contact details can be are be viewed/added/edited.
Messaging API
For the QMessageServiceAction class the following limitations apply to this release:
- QMessageServiceAction::exportUpdates : Full account synchronization currently unavailable due to lack of synchronous control of update progress.
- QMessageSerivceAction::retrieve : Only retrieves content for messages bodies at present. Attachment retrieval overridden by mapi/mail client settings.
- QMessageServiceAction::cancelOperation : Async nature of native calls used to implement service actions means that cancelOperation will only operate on ::retieveBody at present.
- QMessageServiceAction::send: Provides no way of determining actual transmission failure.
Windows Specific
- Windows Mobile backend only tested with Windows Mobile 6.0 Standard and Professional Edition with MSVC 2008.
- Windows Desktop backend only tested with Windows XP win32-msvc2008, and is not officially supported.
- Windows All Platforms QMessageServiceAction::queryMessages does not incrementally emit matching message identifiers or progress information.
- Windows All Platforms QMessageStore::instance shows a blocking modal dialog if MAPI is not installed.
