Crixboy96 , via OnePlus 8T Lunar Silver , Oct 24, 2020 : There have been lots of good updates for oxygen os 11 but they have let down the existing users of oneplus, some the major missing are - 1. By not providing their own apps like Phone, Contacts and messaging. 2. While recording the call, the other end person can hear that call recording is on. 3. In earphone mode OnePlus have deactivated the speak caller ID feature. 4. For facelock they have removed the earlier assestive lighting technique. 5. OnePlus shelf Feature is a major missing as its not able to access from the left side. Would request OnePlus to allow its users to have their own customisation like weather to have google or shelf on the left side. 6. With the change in phone application answering of calls is different compared to earlier OnePlus phones. 7. Gallery app is having loading issues all the times when we open the gallery. each time when we open it images load from 1 which is a bit disappointing. 8. As in OnePlus messaging app we were able to categorise the message as OTP, TRANSACTIONAL, PROMOTION and normal messages. Which is a big missing. 9. ONEPLUS call and contacts app is also a big missing as its entirely Missing in oxygen os 11. 10. Even in call app also not able to switch between sim cards to call. Kindly provide earlier OnePlus call application. As a loyal OnePlus fan, its a humble request to OnePlus team to bring back these features and also to fix the bugs on OnePlus 8T.
