After upgrading A10, 429 sound quality very degrade via headphones and also have video recording problem. When I record a video 1st sound came and then reaction came. Battery back up lightly decrease.
Sound quality performance is under investigation. Could you help us describe which part is not as expected? Do you have a video link for example?
Does the video problem appear every time? Does it appear on third party apps?
Could you tell us more about the battery back up problem?
