Hello Guys

I have a samsung galaxy S5 clone (MTK6582), it has very poor cellular signal reception (from -99 to - 110db) and sometime it says "only Emergency", I know its not the sim card because when I put it on another phone it works correctly and has good signal intensity (-70, -80 db).
I found some repair manual for similar smartphones (MT6582) and it says that to correct poor IQ signal, it has to be calibrated with META tools and RF mode.
I ve got the MAUI Meta tool but I cant connect my smartphone with it.
I am also not sure if this is the real solution to my problem.

Can some one help me with this?

Best Regards,
Enrique

So far I have not been able to fix this problem I tryied to replace RF PA which is an AHORIA AP6693, my next guess is the transiever IC which is an MT6616V.

any sugetions are welcome

Sorry to hear about the problems. The first thing I would do is try to identify where the physical antenna is and firmly press against any contact points to make sure it's properly attached.

I hope you get it figured out. Good luck!
