in short: STAY AWAY FROM IT!

all in all this mp3 player is a waste of resources and the user’s time

(unless someone comes along and fixes the firmware X-D (but the playback problem could also be “in hardware”))

what is great about the player:

  • massive amounts of internal storage 16GBytes for 20€ bucks!
    • plus: Micro SD Card extension slot available
  • mounts like an USB Stick, works with GNU Debian Linux 10
  • has FM Radio
  • button controls make more sense, after firmware upgrade (v1.1)
  • design is okay
  • case/housing is okay
  • display is okay
  • charges via default USB Micro-B 5x PIN (aka old Samsung Android SmartPhone power supplies)

why this player?

yes could user SmartPhone as mp3 player, but should not keep SmartPhone in pocket with LTE, Wifi and Bluetooth all turned on (not healthy)

so wanted something that has does not emit electromagnetic signals at all X-D (no antennas, no modems)

the problems:

the software on the RUIZU X02 (Made in China) has MANY bugs and flaws that render it almost unusable

The MP3 player RUIZU X02 is of course a Chinese, provides with 16GByte internal memory (!!!) + Expansion possibility via MicroSD card enormous storage space, also the FM Radio works and even has an automatic transmitter search, but one of the most important functions of an MP3 player, to play clean MP3s without stuttering, this device unfortunately does not manage.

Unfortunately, the extremely annoying MP3 decoding error sounds again and again kill all the fun in music.

other even chepaer MP3 players for 7€, while catastrophic in casing/housing quality, manage to provide flawless mp3 playback
