U1514906572194 , via OnePlus 7 Pro , Jan 21, 2020 : the slowest phone that i have used till now. im a one plus user since one plus 3 and i have used 3,5,5t,6t and now one plus 7 pro. i m having hang issues on my device. whenever i open an app or camera it takes sometime and i don't know what's happening. i have already done factory reset and i also have done software from authorised one plus service center and im still facing issues. and due to these reasons im gonn change from one plus to other brand. even MI phones are faster than oneplus. and i will not recommend one plus to my friends. because you guys are after making new phones and leaving the rest behind . and it is not affordable to take new phones every 6 months. thankyou one plus.
