What's the deal with Mhz? And different bands??? - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

I've read and seen about it for a while flying through these forums. What's the big deal with MHZ and changing the band to a better one. My question is as follows...
I get horrible speeds here in Colorado. also what is the code you put in. #*0011* dosent work.
ROLL THAT SHT, LIGHT THAT SHT. SMOKKKKE THAT SHT

I believe the service menu is *#0011#.

UK T-Mobile users

Is anyone else on the UK T-Mobile network experiencing incredibly slow download speeds lately? For the past week or so my speed has been pathetic at best and just plain not there the rest of the time. I've gone through various speed tests and get varying results but the Speedtest.net app (the Ookla one) is showing consistently that I'm getting around 5KB/s at BEST download with the average being about 2KB/s. Upload speed is poor at about 50KB/s but compared to the download speed it's motoring. I'd be fine even with 50KB/s download but the only way I'll see that is using WiFi.
Before anyone says it might be the time of day, server used, website, phase of the moon etc I was already noticing very slow speeds when pulling down apps and simple Twitter updates. These tests just confirm it to me. I just want to know if anyone else is having similar problems before I complain. If nobody else is having issues I might try reflashing the radio because the ROM used makes no difference and if nobody else has issues it's all I have left to check.
Just tested with the same app from my front room (where my signal is pretty weak) and I got 1901 down and 280 up. Could be congestion on the network in your area, but I wouldn't imagine that would get noticably worse over a few weeks..

Not sure what constitutes good or bad on this page but can you tell me what you have under Settings > About Phone > Status > Signal Strength ?
Right now mine is showing..... -63 dBm 25 asu (fluctuates to -89 dBm and 12 asu)

Right now, -69dBm 22asu to -75dBm 19asu.. So your signal is fluctuating more than mine, your best is slightly stronger than mine but your worst is quite a lot weaker.
A 26dB swing is quite drastic.. Possibly interference from something? Are you sat next to the LHC by any chance?
What area are you in?
Im in kent and havent had any issues or noticed anything.

Only if LHC stands for Large Hairy Cat
I'm in the North East, joners. I don't remember it being this way when I first got the phone six months ago and it didn't feel this slow a week or so ago either. I initially thought it was using a custom ROM or some tweaking I might have done but I've counted that out now. It seems like it's going to be a mix of congestion and... (pun warning!) my electrical personality.

Is there a Doctor in the house?! (radiation)

I've never been one to buy into the cancer causing aspect of mobile phones, but after recently seeing the City of San Francisco pass a law requiring cell phones show there radiation output it got me thinking .
How much radiation does the N1 put out? How is that in comparison to other phones? Do smart phones put out higher amounts of radiation?
My biggest concern, and what got me thinking was the fact that until 6 mos. or so ago, I only had the phone near my head on the occasional phone call (duh).
But now I have a Nexus dock that I use as my alarm/bedside clock. This thing sits near my head 7-8 hrs every single night running bluetooth, etc.
Is there legitimate reason for concern?
I realize this should prolly go in the overall General thread, but I'm never up there and I'm mostly curious about the N1's radiation while using the desktop dock.

If you're so worried. Move to a cave dude. Do you know how many "wireless" signals and radio transmissions there are in a city?
23548723958723985729837652983572 to be precise.
Why don't you get a Geiger Counter if you're that paranoid?
wait, every phone goes thru FCC testing and given a SAR's rating, and this info is available for every phone on the market. the nexus was rather low at around 0.7 if i remember. what is this radiation thing that san francisco is asking for? i thought it would be the same thing.
for more info on radiation: http://en.wikipedia.org/wiki/Mobile_phone_radiation_and_health
list of highest radiation phones:
http://reviews.cnet.com/4520-6602_7-5020357-1.html
FCC says SAR is 0.37 head / 0.74 Body W/Kg for 1gram on GSM.
international standards use 2grams which would make it max at 1.39. The US max is 1.6
geiger meter isnt going to help -_-

Easy Tiger, I'm not paranoid, just asking a question that I'm sure others have more knowledge about than I do.
And thanks to flybyme's helpful cnet link I found this piece of information:
If you're concerned about limiting your SAR exposure, you can take a few easy steps beyond purchasing a handset with a low SAR. You can text instead placing a voice call, use a speakerphone whenever possible, and carry your phone at least one inch from your body. Some researchers also caution against using your phone in areas with poor coverage since phones emit more radiation when searching for a signal. Children, which have smaller and thinner skulls, should limit cell phone use, and all users, children and adults, should not sleep with an active phone next to their bedside or under their pillow.

Yeah, and the fact that using a handphone also makes you smarter compared to those who don't use one.

X2 compared to GX2

I am really wanting the T-Mobile GX2 and I have read through a lot of posts. I am coming from the Vibrant which has tons of pro's and a few crappy Cons but over all it is a great phone. Even reading through a lot of posts I am still not seeing a few answer's that I have.
One is the Vibrant has 2gigs for app installs. I love this compared to the N1's wimpy 192k. So how much does the 2X have for application storage? By that I mean without Apps2SD.
The screen? Is it a standard LCD? AMOLED? I love the Vibrants screen, but it can be annoying for TXT on some websites.
HDMI output? Is it just a standard cable? and is it a true 1080p on the big screen or a scaled 840x480 that the phone puts out? And is it true mirroring, meaning anything on the phone is displayed on the TV and I mean anything?
WIFI? is it N? Bluetooth? I hear the Wiimote is not working, but I am wondering if the T-Mobile version with the AOSP setup will make a difference.
Speaker internal and ear piece. I am really bad on hearing and I love the Vibrants ear piece as there is an option for HAC mode which CRANKS up the earpiece volume so I can hear in a noisy environment. And is the external speaker loud? Again hearing a game is important and a nice clear loud speaker is not a requirement but a plus.
size and weight? is it a super heavy device? and how does it fit in large hands? Do you feel like it is constantly trying to jump out of your hand? My Vibrant is a bit slick and sometimes I feel like it could just fly out of my hand.
I think that is all I had for now.
Thanks for any of those Q's that you guys can answer. I'm really looking forward to this phone!!
Since I dont have the international version of this phone, I am not sure on some of these things that you mentioned but I will share what I have read so far. I am on the same boat and I am starting to not like my Vibrant due to lack of support from Samsung and also faulty gps. I am considering to buy this phone when it comes out and I don’t think I will ever go with a Samsung phone again.
As far as memory goes, G2X will come with 2gb memory for apps and android system. And it will also come with 8gb storage on board.
The screen is an IPS LCD, I am not sure what exactly it will be called. Since iphone retina displays are made by LG, I am expecting to see similar type of screen. The blacks might not be as good as the AMOLED but it will probably be better dpi, less pixilation. So better text reading compare to vibrant screen.
The phone will will have other similar specs, such as the HDMI output, 512 ROM, 8mp camera and 1.3mo font facing camera, NVidia tegra 2, same wifi chip, same Bluetooth chip and same battery. The HDMI connection will be a micro HDMI to standard hdmi, there wont be any tweaks or adaptors and you should be able to have 1080p signal.
I am not sure on the speakers, others who has this phone will have better input on this.
Size will be almost the same to international version, it will be a little larger than vibrant but same screen size. The weight will be slightly more. Almost the same weight as iphone 4. I believe about 139grams.
Above all this phone will have quad-band data. In other word it will be able connect ATT's 3g network if there is a merge in the future. Also this phone will have a hdspa+ capability, which should be 21mb/s data speeds. But the main reason that I think I want this phone is because it will run on stock android. It will be free of the bloatware and It should look clean and presumably a lot faster. For that reason I am assuming it will take more attention by XDA-devs, and hopefully more custom roms and support.
App install partition is 1.45gb
Screen is a beautiful IPS LCD, as used on the Iphone 4 (LG produce the screen for the Iphone 4) - sharp, very bright, with vibrant colors and good viewing angles
Being an LCD blacks are not as solid black as on Amoled, but blacks are still very good for an LCD and color reproduction is good - it is a very high class LCD screen, pictures look stunning, easily as good as my HTC Desires Amoled screen. Looking at it you wont feel you miss out.
HDMI output is a standard HDMI cable but with micro HDMI in the phone end off cource. The cable comes with the phone. It is true mirroring, what you see on the phone you also see on the screen. Since android itself only support screen resolution op to 854x480 all Android screens (desktop, games etc.) are in this resolution being scaled to selected output resolution of either 720p or 1080p, but when you play video it switch from mirroring to only outputting video in native video resolution, and you can then only see video controls on the phone screen and the video overlay itself in 1080p on the flatscreen.
Wifi is N
Speaker is mediocre - both internal and external - not bad but nothing really special either. No HAC mode to my knowledge
It is not heavy at all, despite its size, which actually doesnt feel that big either, it feels light but solid. The feeling in the hand when holding it is excellent - better than almost anything else. Edges are rounded, even the glass front has rounded sides, backplate are "rubbery" feeling - you dont feel like you are going to drop and its very comfortable to hold and comfortable towards the ear also. I have tried most phones on the market the last 10 years or so and I cant think of anything with a better feel when holding it. Some (who dont own the phone) complaints about the buttom space for softbuttons being to big, but its actually just perfect. The sice means that the softbuttons are comfortable to reach when using the phone with one hand, and it means you dont make accidental touches. My Iphone 4 feel like barbwire in comparison. Sharp, slippery and uncomfortable to hold and to put next to your ear.

missed the topic or something?
Thanks guys for the compares! The 1.5Gb install is a win as I really don't want to go back to the limit app space. And I cannot wait to see the screen in person as the Iphone 4 screen does look nice. The micro HDMI is cool, was hoping it wasn't that special USB plug that requires strange adapters. As for the feel I finally pulled up some pics that shows sizes between the Vibrant and the x2 and they look about the same with the x2 being just a bit thicker, so that would work.
The missing HAC is going to suck as my hearing is horrible and I need that extra sound boost. Guess I'll have to wait and see.. er.. hear it.
again thanks guys for the info especially the app space that is a big one!

Good catch - thought they would list under manufacturer and assumed that it only showed current phone - it actually has the G2x US device. In shows the extra 3G/4G frequencies (the only reason I may get it).
In the list of other software, it does not show WiFi calling - really hope that can be installed.
...furthermore, why is a T-Mobile phone using the 850MHz HSPA band and not the usual 900MHz one? Even if it goes through, the AT&T/T-Mobile merger deal isn't going to take effect until well after everybody's moved on from the "G2X"
Kind of annoying, as pretty much the rest of the world uses 900MHz HSPA

I have posted in a couple other forums and the threads lost all meaning because no-one understood what I was asking so I made sure this time by listing some things about the Vibrant as a reference. All I am asking is for 2x info, detailed better then specs sheets tell, so I can see if the G2x is going to be worth getting since both devices will be very similar.
Sorry for the confusion.

There are several phone companies that are finding it easier to make a base phone that supports more then one carrier and pass it through the FCC. Every FCC filing costs the phone manufacture money and anything to alleviate that cost helps. There are a couple sprint phones coming from manufactures that carry Verizon freq's as well. I think this will be a trend amongst all phone manufactures sooner or later.
Also the 850 to 900 issue, I have no idea, maybe it's because of a spectrum issue here in the states. Or maybe ATT just wants to be different.

850 is an AT&T US band - not 900. TMo has a problem here (US) already with selling possible dead-end devices. And since offering "discounted' devices for new or extended contracts is the primary way of signing up and keeping customers in the US, this could be a real problem to them down the road.
Even though many will move up to a different device by then (AT&T) anyway, it still is a worry point, and according to a few local TMo stores - they are noticing it already.
I looked at the network frequencies on t-mobile.com & on phonearena.com and i say this definately my next phone. It has both at&t 3g/hspa and t-mobile 3g/hspa. I'm glad t-mobile brings this out so AT&T won't cripple it like they do their android phones. Its sad that AT&T customers have to go 5 miles to be able to sideload apps, find out that HSUPA is disabled, and deal with capped data speeds. Phuck that. I like AT&T's service but I never bought an AT&T locked android phone. Hence my rant. I will be buying one and unlocking it to use with AT&T. It might help me out if the merger goes through. Having all the bands would totally kick butt!
Looks like release date of the 15th

That is just enabling HSUPA, which many ROMs do.
If you want it to work for data and not degrade call quality considerably, you must either be on a I9000 ROM or using CM7/MIUI

Upon further review... it looks like the OP of that thread got some positive results tweaking those settings in build.prop
However others got mixed results.
I tested it out quickly and got a slight improvement in download speed but slight decrease in upload speed. I will try it again in a different area this evening, though, because I am testing it in a building with a metal roof and spotty coverage...
I've played around with this the last few months. I've had mixed results. Sometimes it seemed like it got me an increase sometimes not so much. I'm in a rural area and as such I have never seen 5Mbps down. I have seen as high as 4.30 Mbps once in a blue moon mostly after midnight. Its certainly a plausible idea but I cannot say with definite certainty that this will give a speed increase.
I tried it out too but it seems like it is depended on the time and traffic of the server...
Ive seen from .5 to 2.9 on my cappy...
edit: any other results or test to see if there might be a better setting?
Also just updated mine to mosaic.
trickery
I tried putting them in my Nostalgia 1.4 build.prop. See if it makes difference.

I'm in frisco and just hit 3 mbs. Get that in both Denton and here. Have seen as much as 4.5 in both.
I'm on the border of Dallas/Richardson and I get terrible speeds on my Cap. At home I get around 200KBPS if I am lucky. On Monday I was in Frisco with a friend who has an HTC Thunderbolt on Verizon, his 3G speeds were 7000KBPS down while his 4G was 1.7MBPS down. In Frisco I did receive 400KBPS down - wonderful right?
I just tested again at work here in Richardson and out of three test I had network failures. The one test that worked was 67kbps down. This is using HSDPA and a signal strength of -75 dBm 19 asu.
I'm using the newest version of Cognition on my phone. Calls have good clarity and when I am using wifi I get 1.5MBPS down. I don't know why my data service is so bad.
Update: So after typing this post and tested again and got 643kbps down 76 up. I haven't moved from my desk.
That's wild. Metropcs speeds is what you got.
Worst area for me is Rockwall. But at&t is kinda non existent out there.
i'm also on andromeda but got same results on other roms as well.
This is my first smartphone on AT&T and because of where I work I was allowed to get a unlimited data package.
I might try another kernel and modem. Its pretty frustrating that my speeds are so slow.
I'm in Fort Worth and I usually average 4mb down 1.2mb up. I'm also running Phoenix Unleashed 8 with JK4
What is your settings at?
if you did the mod.
I am running stock 2.2 and don't use 3g a whole lot (usually attached to Wifi one way or another), but reading this post I figured I would try running a few tests. With 3 bars of signal strength I got a download speed varying between .86 mbps and 2.07 mbps down over six tests. Upload was never much more than about .40 mbps though. At home my Wifi runs around 9 mbps to just over about 17 mbps for download on the Captivate. The is in north GA, not near a major metropolis or anything.
Im curious about rpicaso's setting for this. Im gettin about the same speed as you bytheme.... i want to be faster!!! haha
Wish it worked.
Rockwall has pretty bad 3G coverage. I have better 2G coverage than 3G at home, so I usually stick to 2G+WiFi. 3G seemed to draining my battery.
I usually pickup towers from across the lake in Rowlett.

4g signal strength health issues

Hey guys yesterday i upgrade to 4g sim card and got 4g signal for the first time in my life lol. However after using for a few minutes using phone i start to feel nausea tired dizzy. Dont kniw why. I guess the reason is the signal from the phone is too strong. My tel service provider use 1800mhz band. Does anyone experience similar issues or is it just my imagination lol
Probably just your imagination! Lol. The SAR values of these phones are within the acceptable levels and aren't harmful in majority of cases. People who set these guidelines and standards go through a lot of research so that we end consumers don't have to. So it is safe to say that it is just your imagination that 4G is the cause. Your mind is just trying to associate two different events; getting 4G for the first time and a random episode of fatigue or a headache. Considering you also mention that 4G signal is quite strong in your area, your phone only requires very less power to lock to the network, meaning very low or negligible radiation.
But it would be best to visit a doctor who may be able to help you with the symptoms.
