Sony a7 iv touch focus problem

[husnu]

Hello people. I have a weird problem which is about touch focus. The thing is my touch focus was working flawlessly. However when i was shooting suddenly it stopped touch focusing. I tried track focusing or focus and shutter. They work without problem. But when i tried to touch focus, screen is responsive to my touches but it does not focus. I can move focus point on screen but it is red. Also another thing is on the right top corner, before i touch the screen, the icon is ok but whenever i touch the screen, the icon turns into x position. Any help will be appriciated.

hi back guys, i solved the problem i wanted to share it with u all - just in case anyone needs it. I went to sony experience center. here is the solution: Pre-AF should be ON + use the camera in shutter/aperture priority mode. (in manual mode still touch focus does not work. But track focus and touch shutter work)
