monika_nimmagadda , Jan 29, 2020 : Hey guys, My mobile fell down on a beach (not in water but in wet sand) and since then it slowed my USB performance.. It is getting unplugged easily and it charges correctly when I use dash adapter but then,when I use power bank it completely slows the charge and takes 6 hrs to charge 50%. ( What I observed is, it just don't say it's charging or there will be no power symbol when it's charging, I only see an LED light glowing when connected to a powerbank. When tested with other OnePlus 5 it's working perfectly) Do you think I need to go to there service center? also how much it would charge?
