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?

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
tried to edit build.prop and patch it but signal when i am on custom fw is at maximum but when i put any stock fw signal goes to the minimum stenth.my question is what should i do to get full signal even if i am on a stock rom...
- the signal i am talking about is gsm frequencies in europe
any help would be appreciated as i need to keep stock fw with a good signal quality
Is the signal strength (dBm) different for each? I'll have full bars on cyanogenmod and only two using stock. But in the status settings my strength in dBm will be the same.
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.
I have tried plenty of roms here.They all have this problem.
And I'm sure it's not my phone's problem,cause LTE is very fine with Miui 7.3.11.
I tried *#*#4636#*#*.
When I used Miui,the LTE signal was stable at -101dBm 39asu or -102 dBm.The worst was -103dBm.
When I used other roms,the LTE signal sometimes got to -112dbm 255asu.
Even if i change the type of network im facing signal lost but on stock works great.
