Fake sdcard checker
This application do writing test to judge whether it is fake.
Note: SD card adopted as internal storage not supported.
It writes data to the SD card until there is no more free space.
And, read the data once written from the SD card and check that the value matches the written data.
When the test is over, the capacity which could confirm the correctness is displayed.
If the displayed capacity is clearly smaller than the capacity of the purchased SD card, it may be counterfeited.
However, if you check against the SD card where data is originally stored, only the remaining capacity will be checked.
In this case, please judge by adding the amount of stored data originally.

Fully checked my 256Gb NM card inside the Mate20Pro. Only issue was the phone stops the app progress and I have to click to continue many times. Great it does both write and read verify.
Thanks god someone created this app, MY SDCARD IS REAL i was doughting (wrong spelling) it was real because it was bought at a night market. Btw the sdcard took a long time to verify even tho it was only 16gb but idc bc it's real.
I just bought SanDisk MicroSDXC 256GB A1 yesterday and still trying "write 100%/read 100%/slow" right now, the progress is really take too long and still going on, but i think it's fine.
It did an extensive test of my newly delivered 128 Gb micro SD, that it was legit. The test results were simple and easy to read.
This app was hiding 194GB on my sd-card. Wasted half a day trying to locate the problem of my card being full, despite having no apps showing any usage. Only after mounting the card in a card reader, was I able to locate the sinner.
This makes my phone shutdown twice while testing/verifying my 16gb sd card without any notice . It makes me panic because i thought my phone was overheated by this app. I'm using poco f1.
I am really impressed!! It is so easy to use and takes minutes to get results! I hope that you create more apps I would use them!!
This map is so amazing you gave me the full accuracy of my SD card this app definitely works 100% I've tested it already I gave the most accurate of all apps so this thing definitely thank you for this app it's so easy and so reliable thank you
A great app to check your sd card, the process is a lil bit slow because it checks your sd card by actually using the storage but very very effective.
It will take over 3 hours to do the fastest test! Maybe this works but I can simply write the copy files over myself to test it 100x quicker than this!
Works exactly as described, great for testing free/remaining space on sd card. Read description before use.
Once installed, all I got was a white and black screen. no good for use with model Zte z980
This can do what you need. But it will take more time to do that (32gb sd card - 10min)
Does the job and suprisingly fast. Took 33 minutes to verify my new 128gb sd card.
after using the process i cancelled and my sd card which i have been using for years is no longer accessible and cannot format
straight forward useful for checking my sd card
Got an sd card and had to see if it was real, this app worked better then 3 others I tried before
Very bad app it shows no sd card but I have sd card on my device
Doesn't give option for external SD through otg
created a test file that filled my sd card with no way to remove it or locate it.
says no sd card and its definitely there lol waste of time
Could do with a better design, but does what it needs to just fine... Verified SD ok, app got to 100% and immediately asked to rate before showing results, great but not perfect so gave 4*, went back to app, but it's now forgotten all the test details! So now back here to downgrade to 2*!!!
