Samsung S3 common problems
 

Hi everyone,

I have here two Samsung S3, each with a very common problem upon Google search, but I haven't found a solution for any. Maybe you can help..

1st I have a i9300 with the very common problem of people not listening well during calls. Already replaced mic without success. Works fine with viber, etc, also, if during call I press a bit harder at bottom of the battery people listen better.

2nd I have a i9305 with a dead lcd. No falls, no cracks, nothing, just went dead! Tried the i9300 lcd and works fine. Already cleaned contacts, lcd pcb and still persists. I want to try a light reflow on the lcd pcb chips but I'm afraid to melt the plastic..

Can anyone help me with either or both these issues?

Thanks in advance.

Up.

Can't anyone help me solve or diagnose these issues?

TIA.

Thanks d-artigo,

Will try to re-heat mic ICs when I get home.

Regarding lcd, could it be a bad chip instead of whole lcd module? Can I apply voltage somwhere in lcd module to see if it works?

Thanks.
