✔ Support portable and adoptable storage as well
✔ Show storage details: free space, total space, mount options, device name

Supported memory cards:
* Basically any sd cards: Micro SD, SDHC and SDXC
* built-in memory (card)

Good to know:
✔ If the sd card is formatted as adoptable storage, the app may unable to access it directly. In that case either move the app to the adoptable storage (change the install storage), or format the storage as portable storage.

How to use it:
First select the storage type you want to test it. You can choose between internal or external storage.
If the app could not detect any SD card, then it will display a "Storage cannot be detected" message, but you are still able to browse it manually (if there is sd card in your device).
After you selected the storage type, choose between write and read test, but firstly always run a write test.
On the first tab (Dashboard), you can see the speed on the speedometer while on the Visualization tab, you can check the current and average speed on the graph.

After the test is finished, on the Results tab you can check the details like processed data, storage path, runtime or speed.
Furthermore, here the app will detect the type of your internal storage (like eMMC or UFS version) and will detect the class for the SD card (like Class 10, UHS-I U1, V10).
Important thing that the app will do these calculation based on the speed, thus it needs at least 4 GB of read or written data and at least 10 seconds of run time, otherwise the result can be misleading.
Finally, you can share the results easily with one-button method.

For professional people:
In the Settings panel, you can adjust the size of the file(s) to read/write, you can change the number of the files (between 1-10).

Good to know:
✔ if the sd card uses FAT/FAT32 file system, the maximum file size can be 4 GB, don't set it higher instead use more files. If you want to use bigger files, format the sd card to exFAT (mostly you can do it using a computer, and don't forget older mobiles do not support it).
✔ If the sd card is formatted as adoptable storage, the app may unable to access it directly. In that case either move the app to the adoptable storage (change the install storage), or format the storage as portable storage.

☹️ I know that the dev did great with all the other features BUT I bought this app specifically for the "test+verify" feature which does NOT seem to work as accurate as "H2testw" on Windows. ❌ 🤔 Idk if this is an Android limitation/issue or if this could be resolved by the dev on their end.

Excellent application! Detailed, with thorough explanations. Love your work, Zoltán!
