SD card slot? Do today's devices need that?
Along with their various advantages, SD cards also have some shortcomings which encourage OEMs to replace SD card slots with USB ports and internal memory in portable devices.
But what if you lose valuable data from such devices which do not have SD card slots e.g like an iPhone?
In that case, you can recover lost or deleted data from iOS devices, iCloud backup and iTunes backup with the help of iPhone data recovery software. The software can recover lost or deleted data due to Jailbreaking iOS device, Damaged/broken/lost/stolen iPhone, Water damage, iPhone stuck in recovery mode, stuck at Apple logo screen, factory reset loop, virus attack, black screen/white screen of death, iOS upgrade etc. Moreover, if you have difficulty extracting information from iTunes and iCloud backup or iTunes/iCloud backup is corrupt or not compatible, you can easily choose the selective information and retrieve them in a simple and secure way.
It is all about business in the first place, as manufacturers want to reduce the complexity of portable devices by removing the detachable battery and replacing the SD card slot with more internal memory. This change not only reduces the multiple things attached to the portable devices but also increases the hardware price. Limited internal storage does not decrease the use of mobile data, but increase the use of cloud storage and online services, etc. where non-removable battery makes the devices disposable.
