Samsung Galaxy S21 5G Battery replacement screen dead
Hello, yesterday I replaced the battery for my Samsung Galaxy S21 5g and everything worked well over the evening and night. The second day I connected the charger and it charged from 15% like until 85% and I observed that during charging the battery was heating but mildly. Next time when I wanted to look at the phone the screen wasn't working anymore, started to display rainbow colors like a flicker when I was pressing the power button. then I disassembled the phone again because I thought I didn't connect the LCD flex right. I disconnected from both ends the flex and blow with the hair dryer to remove any impurities from the connectors. when I turned on again the phone the display wasn't showing anything anymore, it was all black. what do you advise me to do and what do you think happened?

@philippe71167 does it vibrate when you turn it on? Does it ring when somebody calls your phone? Based on this "display rainbow colors like a flicker" it is possible that you have a bad LCD.
