Hi, I have a near 4 year old iphone 6 plus 64gb. My problem is; Power button physically clicks, and looks like working but its not. Sometimes when i push home button, it takes screenshots, or sometimes phone tries to close itself. Button clicks, but not working. I use assistive touch. Interesting part is; I know that i need to change the power-volume flex. I took the phone to a local repair shop. 3 days. Everytime he changed the flex, or he said like that. I use the phone perfectly till night. After sleep, when i wake up, i see that again button failed. This is the 3rd new flex, 3rd morning and again power button failed in the morning again. Ps: i dont leave the phone on charging at last two nights, first night phone was charging. Ps:I tried reset setting, didnt work. Ps: At first, i had also another problem: my ear speaker sound was very low, he changed it, now its ok.
It started to work again by doing nothing.
Does home button work at all? It should never screenshot the screen unless the home button is pressed at the same time.
