Problem Problema casti P 20 lite


Hello. Today there seemed to be a problem with the phone. I have a P 20 lite and today it stopped reading the pair of headphones. I have Sony MDR-XB50APL and I have been using this phone for 2 months. They have gone well so far, I have not had any problems. Now every time I insert them into the phone, they don't work. I left them, tried them again, nothing. I tested about 2 pairs of headphones in an Altex and they worked on the phone. I tried the original headphones of the phone and these work. I tested the Sony ones on a J5 and they work very well. I don't understand where the problem comes from. Both objects work, but they no longer go together. Any idea? Thanks
