Usually it works normal. But after I update it, the sound volume is reduced by 30% something. Usually, I listened it on my phone with 40% level of volume, but now I have to set it up to 100%, and for other station the volume is still too low. The last year version seems ok & normal. The apps sometimes stop suddenly and crashed. I believe the issues is on the software & hardware compatibility. Do not assume people are changing phone every year ! Better to use the last 3 year technology !
