Reverse Polish Notation Financial Calculator App

i have had quite a few thermal phones, and let me say, this is the BEST to date (feb 2023). The PX1 is layers ahead of BLACKVIEW, CAT,DOOGEE,AGM,etc... (its funny because the PX1 is AGM-but the upper brand version) Infiray refined the camera and software to great sucess. Your paying for the details, and its worth it. Yes their is a lot of options and even more comming for thermal phones, but this device Stands out to me in so many ways. The size is perfect to me. (think how a premium flagship feels, and then one-up it) its got built-in bumpers that feel well, and inspire how you hold it. Cameras are great (both), and its not a top-teir samsung/iphone class, its plenty amazing for myself. (i am not chasing DLSR). Software side, this device has much more polish and finish than most. its only android 11, and i doubt it will be upgraded because thats the nature of oddity devices. Still, once you start diging into the ROM, its refind in ways , very few other companies do. will i root/hack it?? yes, but not right away. its a pure android experience, and to compare this to a major brand is foolish, because it has ZERO bloatware! AGM has been slowly building quality and INFIRAY picked a real gem to polish/tune. important- if you get this, make sure to upgrade the thermal software (its inside the IR app itself, under about/settings) it adds a few more tweaks and features. The macro cam works great but i also use a premium camera app from PLAY store. (not stock app) If Infiray continues to repeat this, by doing another phone, i can say with geeky-ness , i will be watching very close. closing- i really hope, the other companies watching this , learn and can strive for this kind of polish and finish. (ps: this device can handle a 1TB micro SDXC card)

I've been using this for work for a few months now and it's been working great. I set a programmable key for the calculator app which I use frequently. With use of 8 - 10 hours a day the batteries have not needed to be changed. The mechanical keys are much more accurate that the standard I've been used to using. Much easier to type on.

This replacement seems just as good as the original. Be careful on sizing. The lens itself will have a notation as to what size it is. Order the same size lens cap. Always appreciate the good prices and prompt service from B&H.

The 10 stop filter is simple to use with the long exposure calculator.

Photography in a dark room. Love the calculator being available at all times

Love the reverse stand.

I decided to try this unique paper out,,great way to try new paper without a large financial commitment.

Very nice to polish and wipe clean your cameras and lenses

This calculator is beautiful, stylish and perfect. Item exceeded my expectations. I would purchase again.
