My N900T has much worse signal than my previous Note II - between 15 and 20 dBm worse, so essentially unusable out in the fringe area I live in.
I'm running SlimKat 9.0 (4.4.4) baseband is N900T UVUENK3 (which I think might be the most recent modem).
I'm using a StraightTalk ATT SIM (phone is unlocked) but that shouldn't matter for signal strength
I've got Preferred network type: LTE
And in service mode / phone info, I have preferred network type: LTE/GSM auto (PRL) - unchanged from standard.
I've removed the back cover (the one under the battery door) and made sure all the "fingers" make good contact with the contact pads that are built into that cover (fixed my GPS but not baseband)
Anything else I can check? Should I try some ATT radios to see if signal improves?
Or is this just the nature of the beast? Move to the city or get a different phone?
Thanks for any input!
Had this problem but hopefully the fix I used will work better. I flashed pac rom from nightly and resulted in no signal even though showed 3 bars(never higher or lower) but no connection in reality. Tried this and got signal kinda ( very slow and missed calls and sms)
Anyway
On tmobile network but might help either way idk never had att.
First goto
Settings/More Networks/...
Then first try the lte if not heard using 3g can fix signal connection with custom roms.
Check your apn settings and verify with att/simple talk
And if needed hit the mobile operators and let it do its thing.
Still not working can try fixing another way let me know.
Screens attached and can't post link ig but quick Google search should net you the setting. I did keywords "att apn settings"
Let me know how it goes. Flashing pac rom see how update goes this time for me lol
The signal got a good bit better when I replaced the antenna signal cable. Cost a whole $3.
I'm still 5 or 6 dBi down from my old note 2, but, from my forum reading, that might be the nature of this beast.
I have same problem, poor network, and sometimes when I go to some club or cafe I dont have network and on S2 same network I have full signal 3G, H+

I have noticed in the past few weeks that my signal reception has gotten worse. Places where I usually get 3G and HSPDA, now I only get Edge. It's seldom I get 3G anymore anywhere.
I am currently using K's ROM v1.30b. I tried a bunch of different radios as well, but no affect.
I am wondering is there something that can cause the signal to drop like that? Is it ROM dependent?
BTW, I'm on at&t in the midwest.
No one knows what can cause this?
Unless you have handled your device badly then it sounds like a transmitter issue. What radio version are you using? Also go into: start>system>phone>band
tell us what settings are selected.
The reception and etc....is attributed to the radio stack version, nothing else.

Thank you for your reply. I've used the following radios:
1.47, 1.48, 1.50, 1.54 all with approximately the same results. Meaning mostly Edge network everywhere and very very rarely 3G. Whereas it was 3G mostly before.
My settings are :
Select your network type: GSM (Should this be Auto?)
Select your GSM/UTMS band: Auto
Dont forget that sometimes the problem can be on AT&T's end...
The tower by my work has occasionally gone screwey for a day and all I can get is EDGE, or sometimes 3G with only 1 or 2 bars before switching to another tower on EDGE (normally full bars).
It's happened 4 times in the last year, each lasting only one day.
Go to a friends house or somewhere else and see if 3G comes back. If so then it might just be your local tower, esp. since you have tried so many radios without a difference.
EDIT: just read the above post..
Network type MUST be Auto or WCMDA for 3G to function!!

Your troubles as shown in the post above this one....your mode is set to GSM....hence why your device will not work on UMTS/3G unless the mode is set to WCDMA or auto.
Ive recently attained a captivate glide and unlocked it to use on t mobile. Like you would assume at first glance i had an edge connection. Although after messing around with it i realized by going to
Wireless and network > Mobile networks > Network operators >Default setup > Manual it gives me the option to choose to connect to att/ tmobile and when i chose tmobile and it registers on the network i get H+ speeds for a few minutes then it just defaults back to edge
is there a way i can keep my phone on H+ at all times because its capable

I have this problem too, but only into my house. Outdoor that´s right. I´ve tested with all modems, and I think the best for me is i927UCLH2.
Which rom, kernel and baseband do you use??
I´ve done some tests with my glide and my mother´s galaxy chat, in different places. In the street I have H+ and she H, but when we are into any house, under any roof, she still has H, and I only have E.
Does it happen to you?

Doesn't this just sound like a basic signal issue? When the signal gets worse (indoor vs. outdoor) it will drop down to a lower signal.
Also, are you sure Tmo has fully rolled out the 1900mhz band in your area? They may not have complete coverage yet.

i'm sure that it is a phone or a software phone problem, cause i've put my sim card in my last phone (xperia pro) and it has H signal too
i've tested all rogers and att modems, and still have the problem..
Hi, I have a similar prob, I'm in the uk and need it to stay on H+, as it'll drop off to 2g in the house, I've always used miui roms in the past and they have the option to force 3g etc. The only way round this I could find is to use 'pimp my rom' which allows you to select which network you want manually, such as gsm, edge, wcdma etc. Download it, go to tools, device hidden menu, turn off radio, wait, turn radio back on, then quickly select from the drop down box what signal you want, I select wcdma only. If the radio does not come back on, put on flight mode then off again, and will work.. bit annoying but works..
That happen to me too, but not for t mobile, for a operator that use 1900mhz in my country.
hey gang i'm running the latest aokp task650 build on my S3 I747m. Everything works awesome, except i occasionally lose my data connection. I'll notice my connection status bars are gray, and typically a reboot will fix it. I'm sure going into airplane mode and back out from that would re-establish the connection too.
my APN is set correctly, i compared it to a friends nexus which is not rooted.
Right now i'm set as pda.bell.ca
I've flashed the latest bell modem file (that i'm aware of).
Anyone have any suggestions? i'm pretty new to all of this.. not sure what to do to troubleshoot.

I've been having problems lately when I have poor 4G (LTE) signal. My phone would rather hang around on the LTE network with little to no signal before it switches over to 3G. It's been doing this for a while on the Rogers network for me. I can see when I check the battery stats just how much time is spent without signal which is a lot. At work I get full bars 3G when at my desk but very poor 4G. The only thing causing me to loose signal is the poor transition back and forth between the two networks. Changing modems has absolutely no affect on this matter and I've put the APN's and network modes through the ringer with no change either. I've tried it all and nothing improved it. When I walk outside I immediately hit full bars 4G. Just when I'm inside my work and at home, I get poor lingering 4G. I wish the thresholds for when it switches over were better. I usually just turn off LTE all together which sucks but oh well.
I don't think we are the only people with this either. I've read grumblings about others noticing the same thing.
If curious, I'm running the latest CM10.1 nightly with Ktoonsez kernel on the Rogers network in Ottawa.
Interesting, that could very well cooincide with what i'm seeing. I tend to bounce from 4G to H+ or 3G, i wonder if it's trying to hang onto 4G.
Is there a way to force it to stay on 3G? that might be a good test
I was getting the same issue.
I did a factory reset and reinstalled my ROM plus GAPPs and the issue resolved itself.
I am using the latest modern right now and not my bell one. I think it's from a south American carrier, but bit 100% sure of the top of my head. But it is in the current modern thread
Sent from my SGH-I747 using xda app-developers app
I bought and unlocked galaxy s3 att in India,I live in apartments,I'm getting 3-4 bars when I sit near the windows and when I come to room I loose signal,And the strange things is When I hold my mobile with left hand signal drops like crazy leaving only 1 bar,I tried Carbon,quantum,Slimrom still none resolved the issue
I updated my modem to UCDMG2 running 4.1.1,still same problem,And another things is 4g icon it shows still connects to 2g networks,I mean speed is worse like 2g still it shows 4g,custom roms too have that problem,when i select LTE it shows H+ only and I get 2g speeds,I'm using airtel network,they have good coverage and network speeds
Did you check your APN settings to see if they are correct? There is an option sometimes that will push for 2g. Also if you are using multiple apns there are APN types that can be put in that will make it choose that APN as a priority over others. I am not certain without looking it up but I think it may be "hipri" don't quote me though.
For example if u had multiple apns and that type was liatedbon one of them other than the correct one for say proper late connection.. It could perhaps use the one you are not wanting
This is just me reaching and it may not be The cause but doblook at your APN settings.
First I'd research what the current correct APN setup for your carrier is
Good luck
If you want to see your true connection, go to Settings > About Device > Status > Network Type
Have you checked to make sure your carrier uses the bands/frequencies supported by the device?
Thanks fo r your quick response guys, But I'm using quantum rom now, Even If I select 3g or Lte it shows As if it is using EDGE,
3g and 4g are not currently available in our area ,and that Grip problem persists too, I loose signal if I hold both sides of my device with on e hand , and it gains signal bars if I release the left side of my device(I heard the antenna is situated at the bottom of device )!
So, i'm in the UK with my nice shiny OP3 (on Three UK) - I am rooted with twrp, but same applies on stock.
The radio in this phone seems to prefer H+/3G to 4G, even though where i live, i have full bars on both. My nexus 5 always prefered 4G, and the OP3 is set to prefer 4G but 90% of the time drops to 3G/H+
Another interesting thing, if i use the testing menu to force LTE only, even if it's on 4G already, completely stops any signal getting through for a number of minutes until it decides to connect sometime later. I have full LTE signal in my room too.
Is this a radio problem that could be solved in the future with a software update? not seen anyone else with this issue!
FYI, when it is on 4G, it's super fast and stays connected until a reboot, where the whole process starts again

APN Is exactly the same as my nexus 5, and i even added a new one. Same deal.
I'm an IT Professional, just not a developer. i've done everything i can think of. 4G does work, but only when it wants to. My phone is also registered with my carrier correctly.
Bump on this anyone?
I am having a similar problem I guess. I have the dual sims installed and one sim randomly shows no range. Further, the network preference is not the way it is supposed to be - Chose it as 4G and if 4G is not detected it falls back to 2G.

Same as you. Anyone know how to fix the network priority to lock onto LTE first and then drop to 3G for calls?

I did notice when I do have LTE it's fine but it won't re lock onto LTE after a call on Three where it has to drop to H
I'm having a problem where the phone catches 4G+ "carrier aggregation" and it'll jump from to 4g+ to 4g and back to 4g+ really fast like almost flashing . And speed test are showing low numbers. T-Mobile USA.

Same here. Sometimes it just locked to 3g/h+ in a strong LTE area for no reason. I'm on stock oos with one sim and 1 apn. Sometimes I need to reboot the phone to get LTE back.
Sent from my Pixel C using XDA-Developers mobile app
I first put my sim into slot 1 when I first got the device, I was having the exact same issue. I found that the data priority sim, or if you only have one sim needs to be in sim slot 2.

Yes exactly. And even then it doesn't show up straight away despite 3/4 and usually full signal. Sometimes just putting it into standby mode and leaving it 20mins can sort it... Until I get another call lol. Wondering if it's just a software or firmware issue that could be patched. Lte is fine it's just never preferred despite the options being set

APN is not the universal response. Here he faces a problem of inaccurate network type choice, APN is only to have acces to internet through the provider's proxies. It's a radio problem clearly, the baseband is probably to be corrected by OnePlus.
It's really a strange thing to see those network type issues, MMS issues are still present after all those years.

This is what I thought. It's probably an easy fix for oneplus or rom developers. Custom radios are nothing new. Let's hope so anyway!
This is happening to me as well. I'm on three in a strong 4G area but it always prefers 3G it's so annoying hope it gets fixed soon.

same problem here.
i tested op3 with 3 different carriers
on two of them - lte no problem, instant connect...
on third sim - slow connection, frequent out of range. almost no lte.
tested third sim on iphone - instant lte connect, no problem.
seems like a incompatibility with an selected cellular operators.

Could be but I'm doubting it. OP3 Has full support at least for my carrier on both bands they use (3 & 20).. Never know, the devs here will figure it out if oneplus don't

Same issue here, have never got it to say 'LTE' for me since I got the phone, best it does is 4G whilst my Galaxy S5 would happily pickup LTE. Just wondering what UK users have there preferred network type set to? Mine is on GSM/WCDMA/LTE I assume that is right as that is what it went to itself and have tried LTE or LTE/WCDMA too.
