What's the best unlocked phone for a fruit grower?

Getting some great suggestions thank you! I did know from a previous post from @MES111 about the add on lens to see the psylla but I was hoping the cameras would be more advanced by now on the phone. See his old detective work here Recurring Problem Pears Every Late Summer - #12 by MES111. I’m asking for a lot from a phone because effectively they are not really a phone they have became a lightweight computer I use for most of my business.
