I just got my new Samsung Galaxy S5, original ROM with version 4.4.2. It uses a new Toshiba 64GB speed U3 micro SD card.
When I transfer my WhatsApp folder from PC to GS5, it took me more than 24 hours!!!
The WhatsApp folder has about 3GB in size, and thousands of received/sent images.
At the first time, I transfer them from PC to the (fast) SD card in the phone. It really took me more than 24 hours. At the second time, I tried transfer them from PC to the phone internal memory. It seems to be a little bit faster. I did not wait it to complete. But I assume it will take 20+ hours also.
When I use the file manager in GS5 to copy the entire 3GB folder from SD card to phone internal, it takes only 5 minutes or less. (It's a U3 card afterall)
I did a small test. I transfer only the database files from PC to the SD card (in the phone). There are 7 files, in total 1 GB in size. It takes only 1 minute.
So my guess is, the transfer speed will be ultra slow when it contains many small files.
- The same issue happens in different fast computers.
- I used the original USB cable, and tried on other short and average quality cables.
- I prefer not to pull my SD card out every time. Even if i do, transfer from PC to phone also have the ultra slow speed issue.
- I know there are threads suggesting to transfer file by other methods. But my concern is: Why is it so unreasonable slow? And I prefer using the USB method.
Is my phone a defect?
