The UI issues you are mentioning are very minor and have been like that in Telegram for years. I would say that there are different way to present a feature and coming from Whatsapp you are used to one way of doing things. IMHO Telegram has the best UI and UX of all other "family friendly" chat app. I do agree on the Voice and Video calls that need more improvement.
