I recently switched from an iphone 4s to the new galaxy s5 and the side by side comparrison for signal is terrible ( same network with rogers) my old iphone never had a problem and the s5 is ****e! i have taken the s5 off searching for the lte network because i dont have it where i live with no improvements. is there anything internal i can do or get done to the phone to improve signal? Rogers has absolutely no answers for me!
thanks in advance
I don't think it's because it is s5 necessarily ) I have full all the time with 3g and 2 lines all the time with 4g/lte
Maybe u have aluminium case? Or give it a try with software update... Flash newer bootloader and radio... Or factory reset

Hi, I live in the UK near London. I've just upgrade my Nokia N8 to a Samsung Galaxy S4 (GT-I9505). I was on the Vodafone network with my N8 and I am still on Vodafone with my S4. I never had a problem with the network signal strength with my N8, but the signal strength is very poor to non-existent on my S4. I have seen on other threads in this forum that you can flash the modem on the Galaxy S3 to improve signal strength. Please can someone advise me on the possibility of improving my S4 in the same way, or could I just have a defective phone or SIM card? Thank you.
Bump. I take it that nobody has had an issue with poor signal strength with the S4?
Should I presume that my phone or SIM is at fault?
Hi I have noticed it is a little weaker then s3 but not sure if that is software or hardware issue

Has anyone tried flashing the modem on the S4 yet?
Does anyone else consider their signal to be weaker than their previous phone?
I love my S4, but if I am unable to reliably make and receive calls I will have to consider getting something else.
OK so here is the story. I was recently helping my mother move, about 2 hours away from where I live. I have 5 phones on my ATT plan. 3 of these were there with me (mother, brother and mine). The other 2 phones are Galaxy S III's. They both had 4G and I had R ( i assume that's roaming). I am currently running stock 4.3 rooted with .84 radio. Before my N4 I had a SGS II and I never saw roaming there. So why am I roaming and they are not? I am going back there this Sunday, anything I should try so that I am not roaming? Any input is appreciated.
The N⁴ doesn't have the best antenna. My wife's Note 2 gets better reception than my Nexus 4.
You've got a SIM card, bro. Switch to your old phone when you go out in the sticks. That is, if you still have it.
Hi, I bought my note 3 in UAE and I am using it in the UK. I am on Vodafone. I always get rubbish signal in my house. It is on "emergency calls only" nearly all the time. Also the LTE/4G has NEVER worked since I got it on launch (Sep). Whenever I turn the 4G on the H+ sign never comes up. Some people may argue that Vodafone is a rubbish network. I agree too but I think I may need to flash a different modem? My model is a SM-9005. Do I need to flash a different modem to get the 4G to work? Thanks

You can actually try a different ROM or maybe a custom ROM? At the same time, reception might just be poor in your house. So you might need to make do with regular 3G or EDGE. I no for a fact that in my friend's house i ALWAYS have to switch to 2G because 3G reception is never available, I have SM-N900 tho.

And how about when you set it to HSPA only?

what if i flash a different rom/modem?
I just checked and vodafone operates 4G/LTE at 800MHz. On the samsung uae website it says that the note 3 supports 800MHz 4G/LTE
ROM's won't make a difference as it's the hardware on the device itself.
I also noticed the note 3 doesnt have a superb signal reception... For example in my house my moms s3 and dads s4 have full bars where i on my note have one bar less than they do. Little dissapointed

Check phone status in settings and compare it with the S3 and S4 - you'll see it's just the bar's that show different the dBm's are what counts. You'll see it'll be identical to the S3/4

Good point didnt thought of that
I have the same uae version in Kuwait and also had 1 signal bar at home. Flashed Polish KK after root and now I get 3 bats at all times.

Didn't that trip knox?
Bump... can anyone help me on which modem i need to flash? I checked and the UAE note 3 supports my UK carrier LTE band. Apart from this I always get crap signal.

The device itself has the bands. But you cannot access them by changing the modem. The N9005 supports many many bands but different MPN Codes on each device limit it to specific countries.
It's all a legal thing. Radio frequencies are controlled, unless the UAE version supports the exact same frequency that your UK carrier runs on it won't work. Upgrade to kitkat and test it.

does anyone have this problem? i have a friend in the same room with lg g3 on his hand connected with the 4g lte. i have my note 4 with lte capable sim but i got only h+. i really hate this feeling that the g3 beats my note 4 in connectivity issues.. any help will be much appreciated. btw im from philippines and my carrier is smart. tia.
I thought the Exynos CPU wasn't LTE capable? I thought that's the whole reason why the US (which is where I live and LTE is abundant and a big selling point) variant's all use the Snapdragon CPU.
If I'm right, then your phone can't use LTE because it doesn't have the proper hardware. It wouldn't matter if you put in a sim capable of LTE. It would be like having a WiFi router that's capable of a/b/g/n/ac and trying to use a phone only capable of seeing a/b/g signals. The router (the cell tower) would be putting out all signals, yet the phone would not be able to see the n or ac signals.
Another thing is that you may need to have your provider register the phone's IMEI. I had this happen with my old phone, which was LTE capable, but it only got H+. Turns out that the ATT guy didn't register the IMEI, so ATT thought I was still using the phone prior, which was an S2 and wasn't LTE capable. The was basically a cap on the account preventing me from getting lte.
no sir.. Exynos variants are also LTE capable.. I have my LTE in some open roads when i ride the bus.. but my confusion is that my friend and i was in the same room but he has lte in his g3 (he also have the ip5s but sell it which also have lte in that room) while my note 4 only reached the h+.. it hurts actually.
Well I am on 910C, and I have a pretty good coverage in 4G. I didn't notice any difference when I transit from my Note 2 to Note 4, it is the same reception I have been getting..
well, its hard to accept things in here but I think I cant do anything about it. Thanks btw.

Oh ok. I misunderstood your initial post and I thought I read somewhere that the Exynos version couldn't work with lte.
Stupid question, but are you both on the same carrier? If so then I have no clue why one phone would get lte and the other not. Unless the G3 has a better antenna or something.

Yes we have the same carrier which is SMART. All the difference I know is that his sim came from a smart plan while mine does not. I just bought it from a smart store. I think it wasn't the problem anyway but i cant think of any differences. He has iphone5s before he got the g3 and also got 4g in that room.
I got the same problem as you, and Samsung confirmed that my device has radio defects. And soon I will get the replacement.

Maybe I should go to my carrier because it is a part of my carrier plan. Thanks.
i check my friend's signal and i found out that it has -93dbm and 49asu and having lte(his phone was an lg g3) and mine has -63dbm and 25asu (galaxy note 4) but doesnt have lte. which signal is better? i dont have any idea in here.. thanks.

If possible swap sim card with your friends sim card, easiest way to isolate problem.
i never tried to swap sim card with him but i already tried another LTE sim card but the result is the same. did you think my note has a problem.? im going to attach pictures. mine is the ss and the picture from camera is the g3. we are in the same room as well.
Can you post this two screen shot,this is mine.
no problem. this is mine. I already checked if the LTE is enabled but got no luck. :crying:
Buddy, I sent you a pm.
Your device is defect, i've returned a 910C with a problem like this, no calls possible in 4g3g2g and 3g2g auto mode, extremely unstable lte and umts data connection, etc. unusable. They swapped the motherboard, i think, because of a better asv group for cpu now and a resetted knox and custom counter. IMEI is still the same. Well, now everything works, i've stable lte and umts and i calls work.

i am really going to report this to them because it gives me too much inconvenience.
Hi guys... i'm actually brand new to the forums. I read threads on here a lot since I will google a phone question & this website usually comes up in some of the 1st results. I never made an account though.. I have now because I haven't been able to find a clear answer on this one..
Just a little back story ; I had StraightTalk with an AT&T simcard from like 2013-2016 on straight talk with an iPhone 5, 5S, and 6 but they were all either AT&T models, or, for example, the iPhone 6 I had was an unlocked model. They worked regardless. & I never had any issues with coverage. I got signal practically everywhere, and had LTE coverage always. It was literally a clone of the coverage you'd get if you actually had AT&T, the coverage maps matched and data speeds weren't even capped, I was getting about 20 or so megs around here in the area, which would have been the same even if I was actually with AT&T.
I went to Verizon postpaid when I turned 18, and wanted to get a new phone, so I was on postpaid from May of 2016 with Verizon until about 2 days ago because they were just getting too expensive to afford. I assumed my experience with straight talk was gonna be exactly the same as it always was when I had them with all my iPhone's. & just to let you guys know, I did much research beforehand & I knew that all of Verizon's smartphone being released these days are already carrier unlocked, & are world/global phone's right out of the box. Not only this, but the model of my Verizon S8 is SM-G950U, which is the same model number as the unlocked galaxy S8 that's not sold from any carrier.
So with all of that in mind, for some reason, my coverage is terrible on StraightTalk. I am only getting HSPA+ ( faux 4g, i'm acting as if you guys don't know what i'm talking about :laugh: ) & when I leave my house, very RARELY LTE. Signal strength is not as good either. I've searched google for hours..... & i've tried multiple different APN's on the phone... but I can't seem to do anything. & I couldn't find many threads on here about it either. I'm just so confused and lost because it is a known fact that the Verizon S8 is a world phone. & the bands that AT&T runs it's LTE on is also the exact same bands that the G950U supports. So is there something i'm doing wrong here? Or something you guys might be able to help me with? I know that with all my iPhone's on ST I was getting LTE no matter what and signal strength was much better. It's just very dissapointing that I spent $60+ on an activation kit, and get absolutely ****ty coverage, and I have no clue what to do at this point. I've given up. For anyone who took the time to read all of this, thank you. Lol.
