Hi, I just noticed that in the charging socket (usb c) of my Huawei p20 is a bit of sand. When I put the charging cable in, I hear a crackle from the sand. Moreover, it is not quite pure and you notice a resistance. Iwi does not blow and shake iwi.
Keep the vacuum cleaner on it
Once carefully with a needle try to remove sand. If that does not help, the expansion of the charging socket helps.
Attention in this case you need the necessary equipment, if you have any questions leave a comment.
I would try using compressed air first. Either you have access to a compressor or you buy somewhere compressed air from the can.
If that does not help, then you could take a toothpick or other sharp object (preferably non-conductive) and try to loosen the grains of sand that way. (best use additional compressed air)
If that does not help, then you would have to replace the USB port, but you have to open the smartphone…
