I purchased Nokia 6 yesterday and I have certain issues.where is a default gallery app to view pictures and videos. There is no app to view my files on devise. there is no fitness app by default. I was a Samsung user and I feel disappointed to purchase this phone.
Nokia uses vanilla android on its phones. You can install whatever apps you want. Google apps are free, and if you would a former nexus/pixel user you got used to Google Photos for photos/videos, Google Fit for fitness, Google Files for files. Though files browser is built into android, it's accessible through Settings / Storage.
