Hello. I have the latest OOS build on my Oneplus 6. Since last few days, my Wi-Fi and Bluetooth are not turning on. This problem first started with Bluetooth. When this problem began, Bluetooth used to get disconnected from my paired devices and then again got connected on its own. Later Bluetooth stopped turning on and this problem started with Wi-Fi, but Wi-Fi never turned on a single time after the issue. I also tried resetting the Network settings but nothing worked. Before this problem started, I saw my battery cover was a little open. Water can easily sip through and dirt. Please help.
