There is a very basic feature in other smartphones like āRealme,Oneplus,Vivo,Redmiā¦.etcā to block the internet access for the selected app.
Like if you want to block internet access for Gallery app then you can do it but unfortunately I didnāt found such option in Nothing Phones š.
Donāt suggest for using āNetguardā because they drain the battery much more.
Look at this Screenshot you will better understand.

If Nothing could add this feature then I will be completely satisfied with my Nothing phone. š«„
