Click to expand...
Click to collapse
try another modem, use ICS or JB modem , when ROM is ICS or JB , from My Android Collections
nevermind it wasnt a phone problem, just this phone doesnt like vodafone. i switched over to another carrier and now it works great

Verry strange signal... Stock versus Aosp

I found a verry strange signal problem on my SM-N9005.
On stock rom or on custom rom based on stock my signal is verry poor.
On Cyanogen 12.1 signal is strong.
This using same modem.
For example: When I'm home on stock rom i have 1 maxim 2 bars of 3g signal and sometimes i have only 2g and not a chance to have 4g. On Cyanogen i have 3 bars 4g signal most of time or sometimes full 3g.
I have a friend that have same phone like me and he has stock rom. Sometimes he canot initiate call and I i have full signal with CM 12.1.
Can someone explain this? Why Stock rom has poor signal than Aosp using same modem?

[Q] How can I fix my note 3's signal reception?

So... my Note 3 is like new, no exterior damage at all, I've taken well care of it, but I'm having some problems with signal reception.
Using LTE/GSM/WCDMA mode (or LTE preff with CM based roms) where the phone prefers 4G signal, I have 1 or 0 bars of signal, I miss calls and texts and web browsing using data is really slow!
Using GSM/WCDMA (3G mode in CM based roms) I have like full bars but slow internet using data, I don't miss any calls or texts (at least I didn't notice it) but when I am in the train and I pass through a tunnel, the signal is lost and it never recovers, I have to remove my battery and reboot the phone to regain signal (my other phone, a Galaxy Nexus, loses signal only inside the tunnel, then in seconds it reconnects again like it should, I also have full bars everywhere and no problems with the same SIM card, I also have an LG G2 at home and LTE works very well with the same SIM on that phone, it's just Note 3 that has really poor or no reception at all).
I don't think this is normal and I don't renember having problems like this in the past, how can I fix it? Please help me since I can't find any info by browsing and everyone knows Samsung isn't cheap when it comes to fixing things with knox 0x1, and I am fine fixing it myself if I know what to do.
Do phones use different antennas for LTE and 3G/2G? Is it an antenna problem? How can I pinpoint the problem? How can I repair it?
Thanks in advance.
EDIT: forgot to mention, I've tested this on many custom roms (CM13, CM12.1, RR, N5 ports, S6 ports, Aryamod, Stock Samsung Lollipop, Stock Kitkat) the problem is the same everywhere so I think it is hardware problem.
