K1565009907852 , via OnePlus 9R , Jan 17, 2022 : I have used the phone for only 2 hours and was able to find 4 issues which were not in OnePlus 7 : 1) I have a fitbit smart watch and it used to work smoothly with OnePlus 7. But in OnePlus 9R, the notification feature isn't working i.e. I am not able to view notifcations from my smart watch. 2) The auto call record feature isn't there in OnePlus 9R. And even if we try to record the calls manually, it will send an audio notification ("Your call is being recorded") to the listener. 3) This is a big one. In OnePlus 9R all apps have the same notification sound. In my OnePlus 7 I used to get different notification sound for various apps like Instagram, Snapchat, Zomato, Messaging etc which was very helpful in distinguishing various app's notification but in OnePlus 9R you get the same notification sound for all apps. 4) And yes, the heating issue is real. The rear of phone below camera gets heated during charging. My OnePlus 7 never used to heat. Who would have thought buying a newer model will literally downgrade my phone I request OnePlus team to atleast look into the "different notification sound for different apps" feature. Even phones worth 10k-15k have this feature and a premium phone of 37k doesn't.
