Dualshock 4 problem

Guys, hello. Surely something like this was discussed somewhere, but to be honest, the search did not help me very much: (I recently acquired a Dualshock 4, especially for connecting a gamepad with a PC, I studied everything and blah blah blah, but at the initial level there were difficulties with connecting to Bluetooth In order for the gamepad to start looking for the device's bluetooth, in theory, it is necessary to simultaneously press the PS + Share button on it and hold it for a few seconds, but the problem is that it does not search, or, how to say, does not go into pairing mode. as if I just press one PS button. I don’t know how to explain it, it just doesn’t go into this mode, that is, because of this, neither the PC nor the smartphone stupidly sees it. That is, I press both buttons, somewhere in a second he immediately starts blinking white, but not as it should, quickly and in a certain order (seen on YouTube) but just blinks, as if he is looking for something to which he should connect to the already paired one, in general, as if I just press the PS button, without the Share button. I hope I explained it clearly ... I thought, maybe my Share button is broken, but no, when I connected it via a cord and pushing it, I made sure that all the buttons work. trying to connect. I pressed it in all possible orders - it does not work. If you keep it for a long time, the flashing stops, but then it also flashes again. Maybe I'm doing something wrong? Thank you in advance) maybe my Share button is broken, but no, when I connected via a cord and pushed, I was convinced that all the buttons work. I connected it by wire, everything works fine, installed the drivers, everything works, but it still doesn’t try to connect to the boutus. I pressed it in all possible orders - it does not work. If you keep it for a long time, the flashing stops, but then it also flashes again. Maybe I'm doing something wrong?
