Hi this is PerSee : )
Im using facebook app since 2015 in my android phone and I experinced it very well. Its UI is very smooth and user friendly. Facebook recently updated its android app with best new features. Flow emojis, video downloading feature, photo save with one click, profile features updated now. You dont have to use web browser to use settings or other features, although u can directly open all privacy and account settings within application easily. Notification panel is also smooth and good looking. I think this is the best update yet from fb to its android app. I suggest everyone to use this android app and u can also download it for iPhones.
Thank you!
