Xiaomi India — mi a1 bugs

I newly bought mia1 trusting the band mi but the google ui is pathetic and i face so many problems. Here is a list of problems that i encountered:-
•every contact name appears more than once because of whtasapp and other apps that needs access to my contacts.
•if i type in any number, which is not saved in my contacts, the app doesn't read it. Where else my previous phone used to read my call log. Suppose i received a call from [protected] but i didn't save it. If i press in 877, the app doesn't show me number but only displays saved contacts.
• photos - there is no picture rotate option directly accessible. I need to edit the picture everytime which is irritating.
Some of my photos which i clicked from my phones camera isn't displayed on the photos while it's there in the phone.
•photos - this is a suggestion. I would like a favourite option where i could see my favorite pictures aside & a hide option to hide my pics which i do not want to be viewed in the photos.
•messages - there is no option for selecting multiple messages at a time and delete the same in a conversation.
•battery level percentage is not displayed on the notification bar. I have to slide it every time i need to check it.
•i don't wish to unlock my lock screen using fingerprint sensor but only my apps. If i lock my apps using a fingerprint sensor it unlocks the lock screen at the same time which again i do not want.
• notification bar is accessible without unlocking my phone. So anybody can use my net, hotspot without my knowledge whosever has my hoyspot password saved.
•settings - the settings is very complicated, there are options under options and so on. Always preferred direct convenient options.
• the notification bar doesn't show the speed of the internet.
•phone speaker (During calls) is so loud that even on volume level one, the person sitting next to me can hear my conversation.
I hope you resolve these problems as soon as possible and oblige me. Thanks for your time.
