My iPhone 4s’ touchscreen is not working properly when I am on the transportation. It does crazy stuff by itself, e.g. if I want to click on app A it clicks on the app B, instead. If I want to open the browser it opens the Message or Call Contacts, etc. Basically, the touchscreen goes crazy when I’m on the moving transportation vehicle. It clicks on the places where I don’t click. I just am not able to use it on a mobile vehicle. iOS 9.3.5, 16 GB iPhone 4s. Thanks.
