I don’t know if this is the right place to post about it, but I have experienced a bug on my Samsung Galaxy S9+ while trying different settings from the Developer options menu.
I have been able to reproduce the bug a second time, and both times it resulted in my screen freezing, but the phone still operating.
My steps taken were:
- Select from “Simulate display with cutout” the option “Corner cutout”
- Select from “Simulate display with cutout” the option “Tall cutout”
- Screen is now frozen, but the phone is working. The screen just stops updating the image and the cutout is misplaced.
I did not test if the timing between step 1 and step 2 is relevant, because every time I reproduce the bug, I have to hard restart my phone, as I did not succeed in restarting it the normal way.
I have seen that the phone is still operational through the screenshot I took while pressing the buttons to force a restart.
I will be happy to attach a reply with any logs or details you might deem useful, provided that you instruct me how to obtain them. As for some general ones, I have Galaxy S9+ (model number SM-G965F) and I recently installed the latest software update available, the one that brings One UI 2.0 (I am unsure if the bug exists on other versions of software).
I hope to obtain an answer and that this bug will be solved, as it renders the device almost unusable after the steps are reproduced.
