Has anyone else had an issue with having the phone drop out of 3G coverage, and not want to reconnect by itself?
It seems to me as if when there is no 3G coverage it falls back onto GPRS and doesnt check if 3G is available.
I've set it to WCDMA (3G) only mode just to get on 3G, but it sucks cause I have no fallback and am out out of coverage often enough to take some advantage of GPRS.
Also 3G signal seems pretty weak compared to my HTC Magic in same locations...
Any ideas?
Might be something about your area, I haven't lost 3G once since I got my phone.
Once I put it on 3G only mode it seems to be alright but the odd building I wont have anything cause I have no GPRS to go to unless I manually switch it back and forth.
Maybe I'll call up rogers tech support and see if theres any known issues, but usually Im more informed then they are. :S
I have had this problem, for the first week or so the 3G was rock solid and i was getting pretty good speeds. Then things started playing up and Orange in the UK told me to switch to GSM only, data speeds sucked big time, timescape would fail to update etc etc. So i called up and they are sending a replacement handset out.
The 3G coverage where i live and work is excellent according to the Orange website, so there shouldn't be any issues there.
I could not put up with the slower internet speeds, so i hope it was just a duff handset.
i drove across the US and i had 3g where there were 3g and it was on edge where there weren't any 3g. it went back to 3g once i reached 3g area.
my setting is on gsm/wcdma preferred.
i dunno why yours isn't going back up to 3g in a strong 3g area ??
which carrier are you with?
Rogers in Canada
i would check with your carrier and see a map of coverage. did you get the phone from them?
the only other way is to repair the phone. but losing 3G in a 3G covered area is the first i've heard from the X10. i've heard that the NEXUS ONE has somewhat of the same issue....
Well I know the coverage is there because when the phone is set to WCDMA (3G) only mode, I will have coverage. But when it is set to dual mode, as soon as it drops to GSM it seems like it doesn't even bother checking or reverting back to 3G, even though I am back in 3G coverage.
i'd probably talk to the carrier about it and troubleshoot it. maybe you can see if the phone is defective or not by doing that. and hopefully get a new device.

lol troubleshooting with rogers is like putting a sawed off 12 guage in your mouth and pulling the trigger...
wow rogers service is that bad?
yup sadly. I have dealt with all the majors in North america (even worked for att) and rogers is THE WORST.
"power concedes nothing without a demand. it never did. it never will."
They have been the premier carrier in canada for many years, only recently has telus been catching up. So now they're changing... but they still hire idiots for tech support.
Case in point, instead of giving me apn settings they said my x1 was defective. Found the apn settings and x1 worked perfectly.
Ive had pretty good luck with rogers so far, and I've worked for all the big carriers.
I think with tech support its really hit and miss but id have to say bell is probably the worst for issues, account and phone related...
IMO ...

Funny you said that, I just was toying with my X10 (running on AT&T in Bay area, bought from Rogers Wireless) and its doing the same. Once it goes to Edge, doesnt bother to check for the 3G.. hmmmm.... let me play a bit more.. if i find something .. i will update !!
I lost 3G while in a tunnel today, lots my radio stream and it went Edge, once I was back in the clear it recovered properly.
The program Power Manager, has a 2G / 3G toggle on it, maybe you can use that to force switch it back if its not auto switching.
Ya that would probably work, I'll try it out. Thanks
I was just hoping for fix rather than a work around, lol :S

my rogers on us atnt switches back to 3g. is it because the 3g signal where you are is weak so it just stays on the stronger edge signal ?
cause i swear i drove from somewhere with 3g though many many parts without 3g and now i have 3g again. strange.....
I can go to a location where i know there is full 3G coverage (by switching to 3G only mode) but it wont switch back after being dropped (down to EDGE in low coverage) but it doesn't want go back to 3G by itself for whatever reason?

HSPA+ Upgrades going on in Red Deer/Lacombe
I currently have the the G2 on the T-mobile network. I frequently switch back and forth between 3G and Edge which is driving me nuts. Is this a phone issue or a network issue? Do people with the Desire Z on the ATT network have the same issue?
Its a network issue with your location, It happens on any phone including the iPhone. Its if the carrier has that service available where you are.
I am located in Minneapolis which supposedly has very good T-mobile 3G coverage. A friend of mine who has a G1 on T-mobile here in Minneapolis always sees solid 3G. This makes me wonder whether this is a phone issue. Flashing the 17 radio did improve reception, but not satisfactorily. Could any ATT users share their experience?
I mean, the phone and radio and rom will play a factor somewhat in it but not that much. To be fair, edge and 3G dont have too much a difference in speed or at least not here in Florida, but i run 4G almost everywhere anyways.

For the MOST part, this is a network issue. The phone Radio will have an impact on the quality of cell signal you get but the network carries the most weight. Not all phones are created equal as far as reception goes. My DZ is average. Its not great like my previous BB Bold was but doesn't drop calls like my gf's phone.
I do on occasion drop from 3G to Edge but only when I'm in rural areas. I work in a jail on occasion and of course the concrete walls aren't great for cell signal. I usually switch from 3G to Edge when I'm there because Edge just holds the signal better rather than the phone killing itself trying to find a solid 3G signal.
Also, like the other user mentioned, 3G and Edge aren't night and day per-say. For example, sometimes Edge can be FASTER depending on how much traffic is on the network at that time. I experienced this on a day trip to San Francisco. With 3 gazillion Iphones in the city, I couldn't get my phone to connect to anything with 3G. When I switched to Edge, it was moving steady no problem...
Just my 2 cents.
Is Negri Electronics still the cheapest place to buy the Desire Z NAM or are there other sites with better offers? I checked ebay and all the phones there are more expensive when you calculate in shipping.
Possible Fix
Here is one thing that may fix the problem, as it has for me. Set your phone to WCDMA only by dialing *#*#4636#*#* . A menu will then appear. Select Phone Information. Change Set Preferred Network Type to WCDMA Only.
Hope this helps!

Yes, already tried that as well, but then I lose connection completely intermittently instead of switching between edge and 3G.

I feel very sorry for you then. EDGE makes me want to claw my eyes out versus 3G. Everywhere in New England on AT&T, the difference in speed between EDGE and 3G is like the difference between throwing a bullet and shooting it. Even more so with the "4G" HSPA+ backhaul recently done by AT&T in many areas. But even before that, it was a big difference.
My Desire Z very seldom switches from 3G to EDGE. When it does, its in areas of very weak 3G coverage. As others have mentioned, its likely a network issue. Flashing a new radio is pretty easy (and you can always flash back to stock), so it may be worth a try. But it may or may not have any significant impact.
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

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.
Received the phone today. It keeps switching between 4G and LTE in my home. When I walk around the house, it changes constantly. It might be LTE in the living room one minute, and when I circle around and go back there, its on 4G. Does this all over the house. I am two blocks away from a TMobile tower. My Samsung Galaxy S6 stays on LTE. Wonder what the problem is? As of now, its a deal breaker for me and the phone might go back unless there is a satisfactory solution.
I also have the same problem. It always switches in SIM card status between HSPA and UMTS like it has some kind of a bug. Wifi connections works fine, can make calls and SMS, but the big problem is that I can't connect to the Mobile internet. Please can someone help because this is really disappointing.

Also this constantly switching and searching for network is draining my battery very fast. So I need to switch to 2G to stop the consumption.
I have the 6gb Version and the Chinese Stock Rom and with Tmobile i got 4g and in a City area i get 4g+ but it always works. Do you have a Shop Rom installed.

I don't know which Rom is in my phone, but I think it's Shop Rom because I received it from Honorbuy.com. My phone model is LEX720 6GB ram & 64GB storage.
mine ( dual sim, 6g/64g) was initially from the shop and it had customer rom. but the 4g was very stable. however, i still flashed the factory rom 017s . but with either rom, the phone have been working fine on 4g network.
Mine does 4G and Let switching too. Seems to prefer 4G and kicks up to LTE if needed based on demand. 4G has a theoretical speed that no provider even dishes out that I know of so I wouldn't worry about that. Battery drain could be an issue, but doesn't seem to hurt mine at all (US version on T-Mobile in Dallas). In fact I suspect it does that to save battery, trying to go with whichever is strongest. Total guess though.

How do u get the real APN number. I am on T-Mobile
LeEco Pro3
When you guys see LTE go to 4G, do you see a little + sign behind the 4G icon? If so, that's normal. It's indicating that you're getting TWO simultaneous LTE connections at once (or in other words, Carrier Aggregation is active). Try doing a speedtest and you'll see pretty quick speeds. It's one of the first things I noticed when I got mine.

You should ask on T-Mobile to give you APN number. I got it from my own operator.
I might be wrong here, but isn't LTE and 4g the same thing?
or is it like HSPA+ and 3g (which is not the same thing)
i get 4g everywhere i go, it never changes to 3g or HSPA+ i can't really complain about that, i do however also live in denmark with GSM
I had to change the APN on mine too. Kept going between 3g 4g and no service.
The new ipdate fix this problem. The switch between 4g and lte. Now its lte every time.
I love my 6t it is blazing, The problem I'm having is my signals and data speeds since upgrade from op3. Normally I would average -55 to -80 Max, that's with cloudy sky's bad weather. I live in between the 2 largest cities in the state of Louisiana, Signals are blazing fast normally. I don't know if it's just the radio of the 6t but it's horrible these are my screenshots standing outside in my driveway.

No dropped calls it hangs for about a second when dialing. the problem is data, at&t and TMobile says I'm not throttled an no bad network congestion. According to them my speeds should be above 20mbps and higher but I'm lucky to get 1.2mbps.

Never had issues with at&t or my TMobile service before, what is strange is the data speeds being identical. That has never happened my TMobile service always been faster than my at&t service. I'll have time this weekend to root and play around with network guru to lock bands see if that's helps.

Or try to go to a different carrier shop and ask if you can test out their speeds. See if it makes a difference. Compare it to the employees that work there. If yours is still slow, maybe you have a faulty device.

Im thinking the bands could be locked to one instead of connecting to multiple bands. I hope it's not faulty device but it is worth a shot, I have TMobile service and at&t and they are the same speed for some reason. My TMobile speeds range from 50-70Mbps and at&t 30-45Mbps, Both are locked at 1.2Mbps. I use at&t service for work and TMobile for Personal use. I have the 13 Model so I could test with Verizon.

Let's say it isn't the network. The next step would be to get a new sim card. If that doesn't work, ask your provider to set up your OP6T as a LTE only device.
Well I managed to fix my problem with my network, rooted check network guru everything was fine all bands worked. So I googled stock files flash via fastboot all is good now. Both my networks are back to normal, guess it was just something with the radio. :good:
