Allow me to fix your claims for you to make them factual.
Android sales are high, simply because the devices are almost as good as the iPhones and never better, and in the last few years, Android phones have been setting the pace for new features and latest-and-greatest gimmicks and off-the-shelf generic hardware. Apple has been trailing leading the Android market when it comes to “new useful” features that actually work, and in fact, Apple is behind lagging by about about 2-3 years 1-2 years when it comes to adding actually functional and useful features rather than buggy gimmicks if they actually add utility to iPhones. Apple is not the tech leader anymore when it comes to smartphones when it comes to tech that actually is useful and matters to users.
In fact, I got my wife a $285 Android smartphone, with the latest technology available in December 2016, and at that time, that phone had technology that Apple is just now integrating into their iPhone 8/8s and iPhone X. In fact, that $285 phone came with 6 GB of main memory, and 128 GB storage, and a 5.7 high resolution screen and the Snapdragon 821 processor, which is still considered latest technology processor (only the 835 is newer). Apple’s expensive iP8 and iPX come with less main memory and less storage, and its screens are no better than what my wife’s phone already had from about a year ago. And, she still has no clue about what to do with the many features that she has available on her phone. It’s overkill, just like most smartphone tech.
Your Android phone REQUIRED 6GB of RAM to accomplish what the iPhone was capable of BESTING in performing with only 2GBs of RAM because of sheer inefficiency. Your Android has 128GB of SLOW Flash storage compared to the higher quality FASTER Flash storage used in Apple devices. That "high resolution screen" in your Android was overkill for the distances anyone uses a smartphone.
Here are the facts:
The human eye with 20/20 vision cannot see granular detail less than about 300 PPI at 12 inches (Actually 286 PPI). The average person is defined to have a resolution of 1º arc minute of resolution, which can only resolve a dot of 0.0035 inches at 12 inches. Apple's (previous) Retina display on the iPhone is 40 PPI greater than that limit at 326 PPI, which when calculated (1"/326) results in a dot of 0.0031 inches, below that limit.I will grant you that a person with 20/10 vision, so called "perfect" vision, can actually resolve a dot that is 0.6º arc minutes, which is a dot of 0.0021 inch at 12 inches, which is a resolution of 477 PPI. Only 1% of the population has 20/10 vision. Most of those people are under 4 years old and unlikely to be concerned with using the highest quality of smartphone screens available.
A very rare portion of the population has 20/5 vision. . . above perfect vision, who can resolve a dot of around 0.3 arc minutes. Only those could possibly use the 515 PPI or the really ridiculous 577 of the Samsung Galaxy S6, which has a dot pitch of 0.0017 inch, half of what can be discerned by a human eye and requires the hard ware to push around FOUR TIMES THE PIXELS really necessary for clear images. Ridiculous, especially if they are moving images!
Apple provides just exactly what is needed in screens to animate them most efficiently, not hyped overkill that slows down the function of the screen so that Android users like you can brag about super-high pixel counts.
Your definition of "better" is, to say the least, simplistic when there are far more important specifications that go into the quality of a screen than the excess number of pixels which are indiscernible by the human eye that slow down the screen. For example, such things as color gamut, accuracy of color to reality, etc., of which Apple's iPhones have consistently been rated as the best, are far more indicative of the quality of a screen on a smartphone and for seeing the quality of the photo and video work you may be doing and editing.
Your claim about how the "Snapdragon 821 processor, which is still considered latest technology processor (only the 835 is newer)" is actually false. The Snapdragon is only the latest technology if you are talking about processors which are only available for Android phones. The A series of processors designed by Apple have been consistently blowing the contemporaneous Snapdragons out of the water in all Geekbench speed tests and functions. . . with fewer cores and offer more functions on their SoC designs. The best and latest processors are only available on the Apple devices. That is a fact attested to by the numerous reviews of their performance and capabilities.
For example, the new A11 has something not a single Snapdragon has, a Neural Engine processor which can turn in 600 billion calculations per second. All A series processors since the A8 have had something else that NO Snapdragon or any other ARM based processor has: the Secure Enclave and a dedicated Encryption Engine, designed to provide 256 bit AES end-to-end data encryption on the fly, something no Android device offers, opting instead to provide bolted-on third-party encryption, which, by definition, cannot be end-to-end.
Here are comparison scores for Apple and Android GeekBench tests. Pay attention to the Scores, not the relative lengths of the bar graphs within the graphs as they are relative only within themselves. The scores tell the actual data.
The iPhone 8, 8 Plus were released in September 2017, the iPhone X will be released November 2017. The iPhone 7, 7 Plus and SE were released in September 2016. The various Android models were released in the months and years in the bars.
