As per many recent posts and discussions highlighting problems and bugs in android 10 So should i go for android 10 update or remain to 9 as of now?
Wait for FOTA! It's a good update but you could have bugs resolved by factory reset. Time consuming.
This, if there's really no good reason for you to upgrade stick with A9 for now, trust me the frustration is not worth it. FOTA will come soon.
