My Huawei P9 recognizes inserted headphones only rarely, often only minutes after plugging in or not at all. Once they are recognized everything works smoothly, even for hours. When unplugging is also immediately switched back to internal speakers. Just plugging is an act again… What's wrong? Socket is cleaned. Super annoying. Is there an app where you can switch between internal and external speakers to "trick" the smartphone? Other solutions? On an expensive professional check I have little desire, where the hardware does not seem broken…
Believe the cheapest option is to try new headphones, or which of his friends.
You buy a better cell phone, for example, Nokia p3000 I have is super 👍 a lot of success
Aha… Do you have a Nokia P3000? What fantasy world did you come from?
