I got this iPhone as a shattered one from my friend. I replaced the screen, battery, and did the glowing Apple logo mod. But, the right corner of the screen can dim and brighten, but the rest of the screen is on full blast all the time. It is also worth mentioning that after just 10 minutes of use, the phone heats up quite a bit. Here is the video: https://youtu.be/0yO2vigR3mo
The backlight circuit of the phone is unable to provide power to one side of the backlight. Try getting the Apple logo mod removed as it can damage the phone. The mod takes power from the backlight circuit which can overload it.
