After restoring my original IMEIs on my infinix Note7, I flashed a GSI based ROM which implemented a mac address on my wifi and BT as well. But now under wifi connections, an open network named "NVRAM warning" is showing which actually doesn't exist in my surroundings. Look at the screenshot and guide me what's this?
Moreover, My phone's battery consumption during standby is dramatically increases. If it's wifi card is constantly broadcasting a wireless network (as shown in the screenshot), it may be a cause of extra battery drain when phone is on sleeping state.
