I'm using it without any particular problems. If the signal is good, you can also watch full-segment TV. The reasons for the junk condition are as follows: * The matte paint on the back was sticky due to hydrolysis, so I wiped it with alcohol, etc., and it's quite damaged (still slightly sticky). * The Android version is old (Android 5), and many apps are no longer usable. The main unit only. Please prepare a charger and cable (charging port: MicroUSB) separately. Shipping is planned via Nekopos (mail slot delivery). Please be aware of this beforehand.
