Because almost all smartphones don't have SD card slots manufacturers don't prefer to be used now. There are many reasons why it is for them not to add in smartphones. Because they can be expensive for extra storage SD cards can charge up to 100$ for them to get some extra storage and they are slow.
Manufacturers can charge more for the actual device for the SD card slot. SD cards cannot be reliable for more time they can get corrupted or they can get damaged easily they are not the most reliable source of storage plus they can slow down the device and make apps crash unwanted. It can be a bad experience for the smartphone user because it can lag the device and make apps crash. This point can be the main reason for smartphone manufacturers to remove SD card slots from the devices. Slots can take up the extra space for manufacturers to add a larger battery or camera system. And SD cards don't have much longer lifespan after a certain period they have to be changed and can be pretty expensive for the user. This can be the main reason to remove the slot from the smartphone and make users don't use sdcard anymore. This is a good thing and a bad thing at the time because now users don't have extra storage to store the data they want they have to use an external storage device or cloud storage to store the data. This can be a plus point for the smartphone manufacturers because if the device storage is full the user only has two options either they have to delete some of the data from their device or they have to buy a new device with more storage.
These are some points that can be proved:-
Ingress protection (fewer openings for water to enter through/seal).Storage Speed: SD cards are slower than the internal storage on most high-end phones.SD card variability: (so many various speeds and specifications that most people don't pay attention to, therefore the manufacturer would prefer not to deal with those who try one with the wrong rating and report they're having problems).Sell additional cloud storage.Profits (fewer things = lower costs).People don't care (we all love to gripe about not having SD cards, but most of us still buy phones without them, so they have little reason to do so).
