boneksl · 04-15-2015, 11:14

I have problem with note sm-n9005.
Phone have very poor 3g-lte signal.
I put another board and everything is ok( antenna cable, antena flex ). Trying flash device-OK but still same.

On 2g - 4 bars
On 3g - 1-2 bars
On lte -1 bars

How solve problem? Phone has android 5.0, there is no 3g/4g repair on octopus Why?

Try to write different QCNs and after writing each QCN, check network. Also, check HW.
