Android has a secret place where you can see all the activities , logs , activities of your phone . You can see even after removing the recent apps of the phone . To do this, follow the following activities: Go to the Phone Dialer app. Enter * # * # 4636 # * # * on the dialing keypad . Here you will see all the activities of the WiFi and phone network , including the phone information , name and IP address. Go straight to Usage Statistics without going anywhere else . Now click on Usage Time and select Last Time Used option. From here you can see which apps have been used recently. (If you don't understand or can't send message to me) Thank you!
