iPhone 7 lags while using Apps

Sir I bought a new iPhone 7 last month and i am facing lags during using various apps such as youtube and whatsapp and i also face lags when i swipe up to open the control centre i am also facing some lags while typing some messages. I request you to please fix the control centre and typing lags through a software update as soon as possible. Thank you.
