This is my humble request to Nokia that you should have review your nokia 5.1 to fix some listed problem if you can.
1) Auto display brightness sensor is not working properly untill same has been not stared once again.
2) Their is no provision to send contact card directly through msg app. I.e. no function to add contact details with sms app directly during creation of text msg.
3) In blue coloured handset the memory card slot is not opening properly and smoothly from day 1 of product procurement, as I have changed two times with dealer and still problem is remains.
4) Also battery heating problem and fast drain problem during net use.
Pls check onece all above point and do needfull
