I replaced my Note 5's motherboard. After replacement, I seem to be getting a very low cellular signal. When I connect the old motherboard back, the signal is still low. The blue and white antenna cables seem to be connected properly.
What could the issue causing the degraded signal reception.

I have two weeks old o2x and o2 carrier, and i have very often signal dropping.
It drops signal during phone call or i can see red X above signal bar from time to time. I have to hit automatic search for network to connect again...
Anybody with same problem? Is it software or hardware based?
I have V10C, it is latest for my country...
thx
Mayb your holding it the wrong way.
The antenna is located on the bottom of the phone.
So keeping your phone tight during call can drop signal.
I live in a weak signal area, my power meter (found at: setting,wireless, mobile network settings, networks type and strength) rarely if ever goes below -90 dbm. I often monitor the VZ network by using it. I use my phone for Internet (even with a weak signal my phone has provided me better service than my other options).
I have often observed an odd behavior reported by the power meter, the meter will jump from its current reading to -1 dbm. This occurs only on the 3G network tower. There is also a 1X tower at 4 miles away that I have not observed this very unlikely power reading.
Anybody else have this experience?
Could there be a front end amplifier/attenuator on the radio? If so I would think my phone has a defect.
Thanks

Update: I took the lack of folks having the same problem and another issue this phone's hotspot/tether process to mean this phone had a defect. I was able to replaced it today with a new phone.
I observed that the new phone has the same issue.
Does anyone have schematic for the front end of these radios?
(I wouldn't think this to be possible that LG would give out this information, but I thought I would as)
My understanding is that the radios have not been released, giving us so much trouble getting ICS and other things to work. as far as signal issues... i think it's the phone it self. not yours, but all of ours. I know in a small town out where i live, i have to use a different carriers tower, Verizon doesn't reach well... and my friend still has 4G. he's using thunderbolt, other friend has 3g through at&t... so i think our radios may be underpowered.
hi, i have very weak signal on my n7000 note.
wifi isnt 100% and im only 3 meters from my router.
gsm is poor and most often only 1 stripe signal.
other devices /same provider doesnt showing any problems.
is this a known thing for the note?
any ideas what i can do?
im using xxlsc modem and supernexus rom
(tried different roms and modems but no luck,....)
any ideas?
was the phone dropped? there might be physical damage with the radio circuit or the antenna thus affecting your signal quality.. *at least, that's what i think*
Used my wifes Z1 to test my Z1 motherboard as I was having touch screen issues and a new screen didnt resolve it so wanted to test and see if it was a board issue which it was. Put wifes phone back together and now having signal issues.
Basically all signal reception strength seems to be reduced on all modes, data on 3G and HSPA+ is ok when signal strength is strong enough but on 4g I have very strange problems. On uk EE Although signal strength is reduced data transfer is still ok with 4g. On O2 however even with 4 bars i get zero data transfer. Have a Z3 tablet also on O2 that works perfectly on 4g. Tried swapping sims with the z3 still same result. Tried them both side by side tonight Z1 -95dbm 4g Z3 -89dbm on speed test z1 showed connection issues while Z3 showed download of 16Mbps. Have replaced aerial coax lead and aerial board without any change.
Apn settings all correct.
Any ideas what could be the issue?
Thanks

After i repaired my screen the second time my cellular signal was very low or completely gone. I searched forums to find the parts that are responsible for cellular signal.
So i replaced the following parts:
- blue antenna cable
- gray antenna cable
- flex-platine cellular sub
Now i have a bit more signal but mostly NO signal
2 clips from the middle frame are broken (where the antenna cables snapped in) ... could this be the reason why i have nearly no signal?
I have no idea which parts i could replace to get my cellular signal ok. Please help!
