1. The video format does not support AVI, but only 3GP and mp4.The resolution does not support 320x240, but only 177x144. Unfortunately.It's extremely depressing for me. 2. The audio frequency is adjusted to the maximum, with broken sound.Radio FM is good, it supports external playback, but you need to plug in headphones, chicken ribs. 3. The interface is faulty. There is only one interface, charging and headset.All in one mouth.inconvenient.
summary
It's just that I regret buying it. It's not as good as Tianyu E60
