Frequently Asked Questions
What SD Card Do I Need for HiBy R4?
The HiBy R4 takes a microSD / microSDXC card rated Class 10 / U1 or faster. 512GB or 1TB covers most owners, and the maximum is 2TB. Buy SanDisk, Lexar, Samsung or Kingston from a reputable seller: counterfeit cards are the most common cause of lost files.
Is the HiBy R4 better than the R3 II?
They are different categories. The R4 runs Android, allowing you to install Spotify/Apple Music, but it is larger and heavier. The R3 II is a pure music player (no apps) that is much smaller. Both need SD cards.
Is Class 10 / U1 required for HiBy R4?
Yes. Class 10 / U1 guarantees 10 MB/s of sustained write, which keeps the HiBy R4 free of slow loads, stutter, or write errors. For load times, the A2 (Recommended) app rating matters more.
What size SD card should I get for HiBy R4?
512GB covers light use; 1TB suits heavy use. The maximum is 2TB.
Can I use older or slower cards with HiBy R4?
Not below Class 10 / U1. Slower cards cause slow loads, stutter, or write errors. Check the card label for the Class 10 / U1 mark.
Does the brand matter for HiBy R4?
Yes. SanDisk, Lexar, Samsung and Kingston cards meet their rated speeds. Buy from the brand's store or a major retailer: counterfeit cards sold under those names are common on marketplaces.
What happens if I use the wrong card with HiBy R4?
A card slower than Class 10 / U1 causes slow loads, stutter, or write errors. A card over the maximum capacity or in the wrong format may not be recognized.
How long will an SD card last in HiBy R4?
Several years in normal use. Cards usually fail from wear or counterfeit flash, not age. Replace yours at the first write error, corrupted file or "card not recognized" message.
