Best camera for smartphones

Dec 4, 2018
Hi guys! :)
Me and my friends are traveling the far east (currently in Myanmar), and looking for a phone with the best camera to catch the beautiful views we see every day.
Which one will suit us best? :
- Xiaomi Mi 6X
- Xiaomi 8SE
- Huawei P20
- Galaxy A7
- Galaxy S9+ (rather not expensive...)

Waiting for an answer, thank you very much <3
