Poor audio quality & and bootloop with "speed" button

[Phoeny]

hello i bought this unit

https://www.amazon.de/gp/product/B01B16 ... UTF8&psc=1

I noticed poor audio quality. there are almost no mid and low frerquency audio.

Is there a fix for that ?

Also in the notification bar there is a "speed" button when i touch that my unit gets stuck in a boot loop. until i remove power and connect it again.


If those 2 issues are fixed its the perfect car radio



Also i have noticed it picks up audio with the internal mic instead of the external. But thats a minior problem

Hi, about the audio quality, sometime it have relation with your car, could you please tell us what kind of your car?
Cause this unit is just an universal unit, it does not support the factory amplifier and output some special low frequency audio, you can enter the EQ to adjust the Effect to Jazz or Rock, then you will get the mid and low frequency audio.
About the "Speed" button, when you touch it, the unit will automatically erase some trace and clear up large occupation memory of some apps, this makes the unit run more smooth and fast.
With respect of your issue, it maybe the system error, could you please tell us your current system version?
If we have the new firmware, we can send it to you, then you can try to install it to check.
Regards
