Recently out of nowhere after charging my phone when I removed the plug the notification is saying that phone is connected to usb (computer) and its not going away.....what should I do..... even the phone is not charging fast....plz provide solution.
Then do one thing.... take all the backup of your personal data from the phone.... then perform a security wipe (format) to your phone. After that restore the backup..... in this way all the residue data will be removed.
It may be the data of the apps you are using...... for example, Telegram, WhatsApp, YouTube (Downloads within the app), Games..... remove the apps that you don't use frequently.
