Use microSD Cards On Flagship Phones With A SmartCase

January 26, 2022

Internal memory on Android and iOS devices is very important, especially on those running newer versions of operating systems. Internal memory has been significantly improved, and there are no problems when installing applications. Besides, most modern phones, such as iPhone 13, Samsung Galaxy S22, and others, have over 128 GB and up to 512 GB storage memory, which can be more than enough for many. In addition, various online storage spaces (also known as Clouds) are also available.

Be that as it may, some devices have huge problems with a lack of memory. Users are often confused when the phone warns them that the memory is almost full, and in the category "Memory," it says that there is perhaps over 1 GB of free memory, even though they bought a phone with lots of storage space.

To make things worse, newer phones don't have external memory possibilities ā€“ yes, we are talking about SD cards. And no matter how much you delete photos, music files, or videos, it will not help relieve the memory and install some additional applications.

Oh, how I wish I had my old SD card here! There is a possibility of using SD cards with phones that don't have SD card slots. How? The i-Blades SmartCase.

Why do you have less memory than advertised?

When buying a computer, a console, or any electronic device with specific storage, you will realize that the available free storage doesnā€™t correspond to whatā€™s listed in the specs list. Mobile phones are no exception.

But why does a phone have less free space than advertised? The operating system, the applications that the manufacturer puts in it by default, and even the operator settings take up your space. The problem is that in advertising and when talking about the phone's technical specifications, this amount of storage is included as "available" and as if it were one more functionality when the actual free space, in the end, is significantly lower (tens of gigabytes lower).

The fall of SD card slots in smartphones

From the Chinese company Xiaomi, we get a definite answer from its vice president, Hugo Barra, who clearly says that if you want to make a terminal as high performance, you have to do without microSD card slots. The reason is because of the microSD cards that these users buy later. Many of them opt for a cheap model with inefficient performance. A good range Kingston or Sandisk is not the same as a cheap one that you can buy for less than 5 dollars in a supermarket. Choosing these cheaper microSDs affects the device's performance, thus giving the manufacturer a bad image.

Even microSD cards from the manufacturers named above are still not capable of performing on par with today's internal storage. So we are facing a 'bottleneck' generated by a microSD card. If we did without it, everything would go at the speed of flash storage.

If we do not have a slot for external cards with which to expand the storage, there are several versions of the same phone but with different capacities. Devices that vary in capacity and price ā€“ more storage, higher price. An excellent way to increase revenue.

This is why more and more top-of-the-range terminals do without a microSD card slot, and mid-range or low-end smartphones continue to opt for them. When a user buys a high-end terminal, it is because he wants that 'plus' of speed and performance that he would not have with an SD card.

Clouds are not perfect either

Using the cloud infrastructure, the client necessarily leaves control to the cloud provider regarding several contentious issues that may affect security. At the same time, the Service Level Agreement (SLA) may commit to providing such a service in the cloud area, thus leaving a security hole.


There is currently a weak supply of tools, procedures, data formats, or services that can guarantee the mobility of data, services, and applications. This creates a special dependency for the cloud service provider, especially if the basic aspect (data transfer) is not enabled.

Error isolation

Multiple leases and shared resources are the defining characteristics of Cloud Computing. This category of risk includes the failure of mechanisms for sharing space, memory, routing, and even reputation among different tenants.

Management interface compromise

The user interface for managing the benefits, risks, and recommendations of the public cloud provider for information security is available online and has access to larger sets of resources (than traditional providers) and is therefore exposed to increased risk, especially when combined with remote access and Web browser vulnerabilities.

Data protection

Cloud Computing poses several data retention risks for cloud users and providers. In some cases, it can be difficult for a cloud user to effectively verify how the cloud interface relates to data and thus ensure that data has been handled legally.

Malicious intrusions

Although they rarely happen, the damage that can be done by malicious intrusions is often very great. Cloud architecture requires certain roles that are extremely risky - for example, system administrators and security management providers.

The solution to SD cards in smartphones? The i-Blades SmartCase

A company called i-Blades produces high-end smartphone utilities, mainly protective cases that also improve the phone's performance. How?

The SmartBlade is a small rectangular piece of technology that is magnetically snapped onto the SmartCase, a protective case for flagship phones. When the SmartBlade is connected to the SmartCase, the phone will automatically receive additional storage memory (from 16 to 128 GB, depending on which one you choose). The battery will be wirelessly charged for up to 20 hours.

These SmartBlades, apart from adding more memory and battery life, also include microSD card slots! So if you have your favorite microSD card that you wish to use with new flagship phones, or you simply want more memory, visit and buy a protective case for your favorite Samsung Galaxy, Samsung Note, or Google Pixel phone.
