PA changing is not a correct solution
you just need to change battery[crapy duplicate chinease]
just test it with your test battery [battery from phone with is working well]

just open the battery shield cover in duplicate battery to adjust the weight small rod is inside then it is crapy duplicate chinese battery

post your result

@ARC

If the audio is crackling (distorted) and calls drops, try resoldering COBBA IC !!

All Nokia 3210 and 8210/8850 have a lot of problems on COBBA solder balls!

@ARC

Ok ARC, you changed PA and phone "work" but what is reason his ****n?

- Probably diplexer is bad.

I have few 8210 which in 3 minutes creckling and disconnect call,
also your ear can sense heat at phone.
After change diplexer problem is solved.

Also resold COBBA and CCONT.

Diplexer is small metal box, right from PA. Like a 26MHz oscilator.
So called "antena switch"
You can use shematic diagram.
