Hello everyone!
A few days ago my buzzer stopped working properly - it worked only when i squizzed upper part of my phone. I've disassembled the phone to check what's going on.
Without housing buzzer started to work and then stopped during assembling. I tried to find out what the hell, but buzzer stopped working even without the housing :crying:
Things were getting serious so i took my voltage guage...
[i can't upload photos, so let's imagine antenna board - you can see three golden badges below the buzzer. Small: left side lower[1] and left side upper[2] and big one directly below the buzzer[3]. ]
...and i found ~2V on badge(not sure if i can call it badge) number 2.
I've apllied buzzer between badges 2 and 3 and it started to play music - i thought it was over, but it didn't work properly - it wasn't loud enough and i could hear hum for 2-5 seconds after every played sound.
I've changed buzzer and antenna board for original brand new stuff and... nothing new happened.
Does anyone know where should i look for fault? Any ideas?
PS i've already tested it on a stock 4.3, on CM12 and resurrection remix.
