The upper part of my screen does not respond mostly, in addition to the option button and the button to customize the notification bar.
I discovered that there is a bounding box where the screen does not respond, however, I do not know if there is a way to see what application it belongs to.
I also installed a lot of applications to personalize my phone, including Substrate, Fluid n.g., Rounded Corners, and many more that may have caused all this.
Here is also a photo so you can see what I'm talking about:
So the area I'm talking about is the purple rectangle that stops right above the text (wifi, bluetooth, …)
