Galaxy note 4 Android 5.0 POOR Signal - Galaxy Note 4 Q&A, Help & Troubleshooting

Hey Guys,
I Bought my Galaxy Note 4 a few days ago " In Kuwait - Arabian Region " and I updated it to the new Samsung release Android 5.0 for Note 4, and I have been having POOR/SLOW Signal on my note 4 compared to my old Xperia Z1.
I get low signal and slow data internet I have checked with my coworker and he have the same issue on his phone, but an old Mobile Phone such as the Xperia Z1 with lolipop doesn't have this issue :'(
Does anyone have this issue or know how to fix it
I tried to :
Hard Reset x2 times
Format Phone x2 Time
Cleared Cache 3x Times
Kies firmware recovery tool ( One Time )
And all of them didn't do anything or improve my Signal

Having the same problem here with BOE1, 2 & 3.. it's modem related i suppose.. if you're still on BOC something don't update to any of the BOE versions.. try flashing the BOC5 UAE firmware.. had the best reception with it

I have the same problem in uk. My iphone 6+ was great everywhere.

This has been my experience with the Note 4 as well (I've had it for over 6mo). Whenever I use it I miss/drop calls frequently and data connectivity is spotty at best. Unfortunately if it weren't for the continuously weak signal, this would be a perfect device for me. Even my Nexus 5 has a significantly better antenna/radio.

Agreed. Last week I was on a picnic in the mountains and all of my friends had signal/reception on their phones (moto g first gen, htc 8x...), except for my note 4; not to mention, we have the same carrier... Was quite disappointed tbh. Oh, and I am still on BOC3, as it's the latest official software here.

it's modem related i suppose..

Same issue after upgrading my 910f to lollipop, though I had the same issue with a LG G3 after upgrading that.
I'm in a weak signal area most of the time, and have gone from ~1% time without signal to ~15% without.

That is strange? Have you tried restoring your Note 4 to it's base factory settings?

Same here although if I switch off 4G it's better.

Hi, i change my S5 to the note 4 and doesn't notice better performance, battery last the same.
But i notice reception is worst than the S5.
Because im all day data on and today i see only have 2 bars at home when S5 is always full.
Really don't know what to do.
Top phone S5.

It happens to me too. At first, I thought it was a new feature of the Note to save battery or something like that, but now I see perhaps is a bug, and a common one.

Im now changing for a new one in the store and if it does the same i will change for the s6 or lg g4.

has anyone who has updated to 5.1.1, and was having this issue, seen an improvement?

GPS and mobile died after 10 hours of nonstop use

I have a stock Galaxy S4 google edition.
I drove from Chicago to Philadelphia and used the phone as GPS via Google navigation. I was connected to LTE from T-Mobile.
After I arrived and reboot the phone it stopped getting mobile network (no bars), cannot make any calls and GPS cannot fix the location anymore (in fact gps icon doesn't appear anymore when I run google maps).
The sim card works fine, as I checked it at T-Mobile office and I do have a valid plan and etc.
I tried factory reset, via settings and via boot menu, but nothing changed.
Luckily google agreed to send a replacement.
Did anyone have this kind of issue before?

Although im a samsung owner but I believe that its not a quality devices, I owned 5 HTC devices before the S4 and I can tell you that compared to samsung htc seems like a real genuine device, I just bought the S4 for the smart/air stuff as a change, its a good device but no quality whatsoever

Not sure why you think that Samsung devices are low quality, if you are thinking because its plastic feels cheap then I disagree with you. I had many friends using Samsung devices such as the S3 and Note 2 and fewer friends owning HTC devices. However, my Samsung friends except for one whose phone cannot switch on for no reason had no problems with their phones. However for my HTC friends, one of them who just used his phone barely 1/2 year is having problems with his power button. The other also had problems with his power button and recently his LCD just refused to switch on.
As for me myself, I owned S1, S3 and now S4 and I had no problems with any of the devices. All of them are still working perfectly. I also owned a LG Nexus 4. That device feels more "expensive" than any Samsung devices. It feels more solid but however just using it like 2 months. The power button spoilt. Then I fixed it myself and about 6 months later, the touchscreen's digitizer starts to spoilt and due me giving up that phone for an S4.
This is my second Galaxy S4 GE btw. The first one had a malfunctioning proximity sensor. Basically when you make a phone call holding a phone on a distance, the screen goes black immediately. I returned it to google for a replacement too.

[Q] Do you Have A second Phone?

Just a bit of fun as we are getting near Christmas...
Now we have got our Note 4's & enjoying, I wondered how many of you have a second phone that they switch to now & again?
Do you use a second phone?
If so, What do you use?
I have the Moto X 2014.
Have SM-P605 Tablet and iPhone 3GS and iPhone 4 ass well, sold my iPhone 5 and use now my Note 4
I have a HTC One M7 as the contract still has a couple of months to run and a Nokia Lumia 820 for my work phone
I have note 4 now but i would like a note edge for my second phone
Also have and iPhone 5s. Use it for all my music.
When it comes to output from 3.5mm jack note 4 is no where close to iPhone.
Also I am having issues with camera. The pics from note 4 are blurry and not as sharp as iPhone.
Have tried all troubleshooting tips for camera but no luck.

Well getting used to the Note 4 but I still have my iPhone 5 for the odd thing or two. It's pretty much been downgraded to an iPod.
I have an old LG P925, the big old 3d can phone that I got from aunt years ago. It's quite laggy and the battery life is awful, plus it hangs up while texting or receiving calls once in a while (the microphone turns off once in a while during calls).
I only keep it because it's on the network my family uses, while my note 4 uses the network most of my contacts use. I also bring out the LG when I take public transportation, the Philippines isn't a safe place for fancy phones out in the public
I have a OnePlus One on it's way.

Note signal issues resolved (for me anyway)

I have been a vociferous critic of the Note 3's shortcomings as a communication device. Verizon replaced my first one and signal still sucked. I was skeptical of another Samsung product but, with a business account, I have 30 days to return my new Note 4. It will NOT be going back. My biggest problem was an area where I hunt and since I often hunt alone being able to communicate can be critical. In this particular area the Note 3 had ZERO signal. No 1x, no voice, no text. I checked yesterday with my new Note 4 in the exact same spot and I had -103db of 4G. Not only was there perfect reception for voice and text but also I easily, and quickly, could check email and go on line.
The range of bluetooth connectivity was somewhat better with the Note 3 but I am still experimenting with that. As far as the core function of being first a communication device, the Note 4, so far (and in my experience) is light years ahead of the Note 3.
Now lets get it rooted and start having some fun!
I have a s4 and the note 4 has way better reception than it

[Q] Note 3 with bad signal, any way to work around?

So, I have my old galaxy nexus getting full bars with the same sim card in the same place as my note 3 gets like 1 bar or almost goes off network. Even old Nokia and my mom's G2 have full bars so the problem is with my note 3.
I had a problem with my usb port so I replaced it with this one: http://www.aliexpress.com/item/For-...Charging-USB-Flex-Cable-Dock/32270903770.html
But the problem persists, same weak signal.
I am using SmokkieRom v5 (Note 5 port) but I renember I had bad signal with DarkLord S6 and his Note5 port too. I never used stock so I can't tell because I hate ugly samsung stock theme enough to want to stay away from it.
Tbh I don't think the rom affects the signal strength so I believe it is a hardware fault, how can I fix it?

TMO folks, how does the signal strength compare with GS6?

I live out in the sticks, I rely on wifi calling. I am hoping there is some improvement with the modem. Both my GS6 and Note4 cannot make a reliable call here without WIFI.
Curious to know about this as well..

I have better service so far with the S7E on T-Mobile than my S6E. That's for sure. Noticed last night
I'll be back in my office with less-than-stellar coverage on Friday. My Note 5 used to struggle for LTE until recent radio updates allowed it to pull 3-4 bars fairly easily (not in an active Band 12 area for this office). Hoping the S7 Edge can do this too.
Has anyone figured out how to tell the phone to prefer Band 12 over others? I used the same Samsung Service Mode from the Note 5, but the options are laid out completely differently.
My Note 5 had much better reception inside the building that I work. Hopefully an update will make it better.

My Note 5 & S7E has about the same signal strength. But, from speed wise, Note 5 is pulling about 10Mbps faster than S7E (35 vs 25). Also, another strange thing is that Note 5 is LTE towers while S7E is using GSM towers. I couldn't find any switch to fix that...
Side by side with my s6 I'm getting an extra bar on the s7
For some reason the signal is been pretty spotty compare to my Note 5. Hopefully, Tmobile has an update in the works.
Better signal but more important then that is faster connect. A lot of times on my s6 there would be long pauses before ringing. The s7e is much faster.

I've noticed that my LTE signal in the office is slightly weaker than my Note 5, but it still works.
Noticed my LTE signal is weaker in the office as well (Coming from note 5). Hope a update fixes the issue.
