Fortunately, thanks to a quick contact, I was able to get my phone repaired quickly.
However, perhaps because the screen was repaired in a hurry, two screens appear and a lot of buffering occurs.
Perhaps the motherboard is damaged, but it doesn't seem to be a big problem, but now I won't be able to create my work continuously and will have to cool down my phone in between.
Also, the screen is hard to see, so the ratio can be weird.
