No, there is no purpose for a blood oximeter on a phone. I work in a medical field and I can assure you no medical professional or even itinerant medical purpose can be served by a blood oximeter on a phone. It is a gimmick to add to the spec list.
Where I see android excelling against iPhone is on basic functionality. For example, android is near perfect in voice command (calling up apps, dictating and sending emails all with voice). iPhone just does not do these things nearly as good - if at all.
If at all??? As I said you do not know what you are talking about, not at all. I just told you that Apple devices work fine for voice command and dictation. . . and even from the AppleWatch. . . Yet you claim I don’t do what I and over a billion other people do. My girlfriend uses it in a professional environment for medical work on a daily basis for reports and email. I’ve been using it to write two novels. Apple has had dictation and voice command for almost thirty years. That’s what I meant when you are listening to propaganda pushed by Apple’s competitors.
As for speed? The A12 processor in the Apple iPhones in 2018 were geekbench 4 tested in single core score at 4,701, while the 2019 Snapdragon 855 scored only 3,552, It was a bit better for the Snapdragon’s eight cores against the A12’s six cores, with a score of Snapdragon: 11,196 to Apple’s A11,420, but Apple’s has already been on the market for a year. Apple’s latest A13 is due in September and is apparently due to be on a 5 nanometer scale.
The Apple A12X was even faster than what was tested above and is the equivalent of a desktop processor in a portable device.
Then everyone I do a side by said with must just be using the old iPhone x.
I’ll stand by it does nothing better and you don’t know what you are talking about.
All the Best!
