    Hi all, last night i got a problem with my S8. It started to drain my battery and stay open and i didnt knew why. I open it i saw that on the notice bar it says that "Android System USB connected after that dissconected" and it did it very fast and it had no USB cable on it. Any ideea wich my by the problem ? Today i had the same problem, at the moment it stoped. But i dont know for how long time. Last night after a few resets it stoped. But today it started again. It dose this even in safe mode and i dont understand way it says that the USB si connected after that disconnected if i have no cable pluged on the phone ? Ty and sorry for my bed english.

    Welcome to Android Central! Check the microUSB port to make sure it's not dirty. Use a can of compressed air to blow it out, and a Q-tip dipped in rubbing alcohol to clean the contacts.

    Strange, because the phone is pretty new and i didnt had that problem with other phone like S4 (that had at least 2 years) But i will give it a try. Ty anyway.

    Another consideration would be moisture -- any chance water got into the port?
