I was wondering if this was an issue with any roms or hardware. I have had my mytouch 1.2 since march and have noticed poor signal in areas that i should have 3g based off the coverage map (ex. at my tmobile store i should have 3g and periodically edge but I teeter between edge, gsm and no signal) Im not sure if it is a sim card issue or a phone issue. basically im just looking for some advice to resolve this.
thanks in advance
The reception signal shows 4 to 5 bars, it is changing, there is no simcard installed on the phone. What are the bars for?
I actually get fewer bars when I have a SIM card in it (sad state of AT&T)
911 emergency calling I would guess
Yes, when you have no card inserted, it latches to the strongest signals for 911.

Thanks guys, all other phones I had displayed no bars or had X on reception but still allowed 911.
I see LG G2 displays the signal strength even with no SIM.

Hey guys just wondering if there are any exynos users who have T-Mobile in the USA (Atlanta for me). Im using the n910U and i get a 4G signal pretty much everywhere but out of nowhere it will drop to 1 bar, and then drop signal all together. Its getting quite annoying as it was said that the unlocked version was supposed to work with T-Mobiles LTE bands. It also happens when using the download booster which is also a pain. Any suggestions on improving the signal? thanks in advance.
Bump. Anyone have any advice to remedy this?
Im planning on buying the sm-n910u aswell but I want to use it with metro pcs which should be using the same network as tmobile, I dunno if ur problem is the phone or network hiccups but im hoping it will work here in nyc

A few things to look at
Try 3g only awhile, you may have a marginal 4g signal and the phone keeps switching back and forth
Try to find out which bands are coming off each tower in your area as well as tower location
You are one of the first to use the new intel modem in the usa for this phone
Keep us posted
Back in the HSPA days I had nothing but international devices and frequently experienced what you described. All the carriers have different networking h/w and topology because they all grew through acquisitions. If I left my home town where I had decent coverage when my flight would land in another region I'd have to reboot my phone to get it to connect to the network. When doing speed tests with friends using "real" AT&T phones their phones were always faster and more reliable. It was only an issue less than 10% of the time so it wasn't a big deal (to me). For better or worse the carrier's optimize the radios in their phone for their specific networks. So, at least in theory, a carrier phone (used on the carrier that provided it) is always going to deliver the best performance.
I got my N910U from Hong Kong, and my 4G signal is as weak as hell, though i'm a China Unicom user.
My iPhone 5s has much better signal than it, same SIM same network.:crying:
There must be something very wrong with the Exynos version of Note 4.
Hope Samsung could fix this ASAP.
Yea it happens pretty randomly in my house and when i leave to drive around town. The signal will be 4 bars on 4G then suddenly just drop connection all together for about 10 seconds. its a real drain on the battery when it does it so often. Im wondering if its a software issue with the radio in the n910u? Since we have root already we can load a different radio on it and see if it improves?
Got the same thing going on with my 910U on Fido Network in Canada. I must note it seems like it doesn't affect performance except for a network speed, no issues during the calls but 4G signal is at 1 bar most of the time unless I'm outside in downtown or something. I must note 3G signal was almost always at full strength. Not sure what is going on here but I thing we really could use some modem update here lol

I also have hongkong N910U model and facing signal issue on regular basis. When Problem appear I can not receive calls anymore and when try to make call , signal disappear altogether. After I retry a couple of times then it works fine but only solution is a restart to get the full strength. it feels like it is a software issue rather hardware but still keeping my device in observation. I feel when I enable power save mode only after that this problem appears. trying not to enable power save mode and test the issue for few days.
Kindly also share your own experiences to solve this issue temporarily.

If have exactly the same issue !!!!
Start with full signal strength and going down to the lowest strength and minutes later no signal !!!
Reboot or Airplane mode can undo this, but the cycle starts allover: Full strength, less strength and no signal.
Tried with 3 different carriers !!
And 2 Note 4's !!
I have the Snapdragon version SM-N910F
What is going on ??

Swapped the note 4 again.
The third one and a new simcard fixed the issue !!
3 to 4 bars signal strength/
I have this problem since yesterday, it seem like the Note 4 is dropping the Sim card. In panama we have a provider that will need to register the sim card with names and stuff but i never did and every time i turn off the phone it will pop out that menu from the sim card.
Yesterday it was popping out every 20mins so i assume that the note 4 is dropping the Sim card. i didn't have that problem when i started using it. its been only a week and this problem came out. I got no signal, with the circle and a dash to full signal and drop signal back... all day, I can't even play online or watch youtube or other things. But it work fine with wifi!
I changed providers no more issues for me. Gonna change back next week and a new simcard also
I am in Colombia and my phone always is with one bar of signal, but when I am making or receiving a call it get full bars of signal. Do your phone do that? (I have the N910U)

Have this device on Bell in Canada. Not having these issues at all, but haven't rooted.
I got my lg g6 G600k and there are couple issue which is really drive me nuts! First one is "hd voice roaming is unavailable" keeps showing on my screen frequently. Second, the phone can only do 3G instead of Lte and I am an att user. I really like the phone and the hifi. Plz someone help!
You bought a foreign model phone for use with ATT in USA? Sounds like it's not 100% compatible. Q

I also use the Korean model and I also have the HD Roaming message. But I'm currently using the phone in an area with REALLY lousy ATT coverage. I'm taking 1 bar and 3g service only. A short drive away from here I get full coverage and LTE speed. Never get the message when I have good signal strength.

Ya and I don't know what I did and the message disappeared and the signal switched to lte
I get this problem with my 600S with Fido in Canada. I have strong LTE signals at where i live and it is funny that when I set my phone to LTE only via the KR service menu trying to eliminate this problem, I would get no signal instead of GSM/3G/LTE(from time to time).

u mind sharing what u did or do u not remember... i have lg v20 and have this problem.
So not sure how long it's been doing it but the Sim 1 slot on my phone gets god awful signal, 1-2 bars best, but it still registers as 4g LTE (speed about 70-100Kb/s). if i put my sim card into slot 2, i get great signal but it locks into 3g and the speed only just exceeds 10mbps. anyone had similar behaviour on the dual sim? on Telstra network in Aus if that means anything
thanks
Do u get 1 or 2 bars across all areas or only at a certain place. That could relate to operator network issue and not a phone issue.
