[Q] Galaxy S3 Reception issues. (Rogers/Telus)

hey guys
im in the pickering-scarborough area and my reception sucks. my wifi drops a lot and my signal is weak
i would have returned it but i got this phone second hand and it was originally telus but i unlocked it
when im downtown i get pretty good reception but it still depends on the area that im in.
when i had my iphone 3g i had good reception at home but now i dont
does anyone have any suggestions on apps to help with signal reception. i dont care about wifi, just reception.
I have fresh network but its not that great.
also, are other galaxy s3 users in the gta experiencing reception issues?

im currently running cm10 nightlies (also any suggestions on better roms are appreciated)
i just updated my modem to the rogers basband one. i dont know which one it was before but im testing it out now.

So are you on Rogers or Telus? Because with Rogers, running stock LH1, inside my house I get 3bars on 4G if lucky, my room is the only place at home where I get LTE if at all.

LH1 for Telus is your best bet... Others modems don't connect... Well it depends.. Won't connect with the I747 without the LH1 modem here in Quebec.

Oddly enough, he's in the Scarborough area too. Could be a combination of phone + network.

Look into changing your settings under Mobile Network. Network Mode should be LTE/GSM/WCDMA. Also check your APN's for Rogers LTE. Lastly check your Phone Information by dialing *#*#4636#*#*, select Phone Information and change the setting to LTE/GSM auto (PRL).
I was having similar issues when i first installed CM10. It seemed to work after i played around with these settings. I also live in Scarborough and almost always have LTE.

LTE version vs 3G version, what's the difference?

Hi all,
I know Samsung are making a 3g version of the note 2, and they will also release a 4G lte version. The isn't any good 4G networks where I live right now, but i was thinking if future proofing my phone, and I also might be moving back to England soon. my questions are this:
If I buy a 4G model (n7105 I think), will I be able to flash the international version roms?, I know I might not get the 4G network if I do that, but would I still get the 3g networks if i flashed a different modem?.
If I get the 4G version, I would get worse battery life cos of the need for a extra modem to be running, but will I be able to disable 4G in settings (like I can disable 3g on my s2)..?
And if I can disable 4g, then would I still get the same battery life as on a 3g version of the phone?.
Thanks in advance for any help.
Cheers Corey

yes you are able to disable the LTE network, and choose the GSM/WCDMA instead.
But without disabling it, the network will auto choose the available network. If you current telco doesn't provide any LTE connection, the phone will auto change to 3G.
Like here the telco I'm using, even provides the 4G connection, but, in facts, it is not yet island-wide. So, when I reach my home, it turns directly to 3G. Battery wise, as I notice, is the same. Not much different when you are in 4G or in 3G. But yes, speed is different when you are in 4G.
The only lack of this 4G (N7105), .....
we still don't have specific forum for N7105 (dunno why we don't have... LOL) nor custom ROM. So, I just have to bear with the stock ROM rooted. :fingers-crossed:

Future proof?
Well depends on how long you are intending to keep it. These days people change phone very frequently and LTE is no loss for most general usage of data use.

There is already a 3G and LTE version out in Australian market with a price difference of $200+ with the latter being more expensive.
If you are moving back to England very soon (1 or 2 months), do check out the price and review of the LTE plans and services with the various mobile providers before deciding which version to purchase. Have read online that LTE charges in Europe is a killer and data speed of LTE will be greatly affected by the amount of users at the same time, within the same WAN.
As for future-proofing your phone, it will depends on how long you are using it since nowadays, majority of the ppl does not use the same phone for more than 2 years, which is directly affected by the various 'annual contract plans' which the providers has to offer.
Flashing the International version Rom to my N7105 was not very successful as I lost WIFI/Data/Mobile receiption and I have since unrooted my device..
Waiting for the official Home for N7105 as well.. :fingers-crossed:

[Q] LTE Clarification please

I've been seeing a lot of LTE buzz going around in the tmo GN2 forums and I want to get some clarification.
My understanding is that there are two versions of the T-Mobile Galaxy Note II: SGH-T889 and the SGH-T889V, with the latter being LTE-enabled. I have the SGH-T889. The buzz leads me to believe that the regular SGH-T889 does have dormant LTE capabilities which can be activated by flashing the newest radio. Is this true? Or is it only the SGH-T889V that has LTE?
I purchased this phone fully expecting zero LTE capability. All I really wanted was ~15Mbps, and HSPA+ typically delivers between 13-18Mbps depending on recenption in my area, so I'm pretty satisfied. However, I believe T-Mobile does have LTE in my area, so if my phone does have LTE capabilities that can be activated, that would be a nice bonus.

Reviving my own thread here, but I need some LTE clarification, part 2.
So, I'm in San Jose, which is suppose to be one of T-Mobile's LTE markets, and I have the latest modem (UVBMB4) running Sons of Android build 4. My network mode is set to "LTE/GSM/WCDMA", but I don't see any indication that I'm connected to LTE. My status icon is still H/H+, but one of the known issues is that the icon can be "wonky". Is there anyway to confirm wether or not I am connected to LTE?

I find that hard to believe. Again, San Jose is suppose to have LTE, and it has been reported to reach Fremont, which is 20 minutes from where I live in (North) San Jose.
One thing I've noticed, if I have the LTE option enabled, I'll lose all data connection after the phone sleeps a while. In order to restore data, I have disable LTE, and reset the radio (enable then disable Airplane mode).
I'm fairly convinced it's a software bug or configuration issue, but I suppose I could be in an LTE dead-zone. I also doubt that, since I live in a fairly open area, and cell phone reception has never been an issue for me, not CDMA, GSM, HSPA, or WiMAX, which was notorious for spotty reception. Not to mention, according to OpenSignal, it works down the street from where I live.

Just because they say you have LTE in your area doesn't mean it's fully up and operational just yet. T-mobile is still working on getting ALL the towers upgraded for LTE. Give it time and you'll probably see LTE start popping up more and more.
And before you make comments about how they should have been prepared blah blah blah; go check the LTE thread because it's been done MANY times.

[Q] Signal issues i747 on T-mobile. Any help or suggestions appreciated!

I have an unlocked AT&T i747 on T-mobile's $30 100 min unlimited text, and 5GB 4G data plan.
It is running a fitsnugly nightly build of CM 10.1 for d2att
Was previously running Leankernel and now i'm running Ktoonsez's kernel
I unlocked using this method.
The Issue: My signal switches between H+, 3G, E, and rarely G. All while being in the same spot. It spends 90% of the time on E.
This happens in areas of great reception, indoors and out.
Rarely will H+ happen and 3G is very sporadic too.
I live in the heart of a major city (Boston) where T-mobile is prepping LTE so I can get their 3G/4G on the refarmed 1900MHz and without AWS.
My IMEI is listed in the status section.
What I've tried:
Before doing any modding of my phone, I previously backed up my EFS/IMEI with Andromizer (XDA link). Restoring it hasn't changed anything.
Changing network modes (LTE/WCDMA, LTE/GSM/WCDMA, GSM/WDCMA preferred)
Enabling/disenabling data roaming
Changing APN settings (The choices were T-Mobile US and T-Mobile US LTE)
So would flashing Tmobile radios help? Tmobile/d2tmo ROMs?
TL;DR: MY ATT I747 ON TMOBILE WONT KEEP THE H+ OR 3G SIGNAL AND IT SUCKS AND MAKES ME WANT TO CRY. PLZ HELP PLZ PLZ PLZ
Seriously though, any help would be appreciated. Thanks everyone! If you need anymore info Just let me know.

This is pretty frustrating. I changed my modems to an older ATT one, and now I only get 3G sporadically and 90% of the time its on G. So odd...
Also I'm pretty sure I'm specifically not supposed to flash a T-mobile modem....

Thanks for the advice but I read through the thread already and it doesn't seem like it will improve drastically. So I rather not attempt to flash a modem that may cause a soft brick. My brother has a N900a and gets almost triple the speed of my lte. What gives?

I dont always get fast speeds. I'm guessing at&t phones get higher priority than other phones. There is a build.prop that you can flash/edit that may or may not work. I, myself, haven't made any mods because I get higher speeds usually. Not always. I am on a 900T but using an international 9005 rom with T-Mobile modem still. It really boils down to is the risk flashing a modem or build.prop worth it. In downtown houston I rarely dip below 10mb/s on LTE and occasionally see over 20mb/s. The congestion is real bad here so it is very often I get bumped back down to hspa. Like I said, you have to weigh the risks. I am fine with how it is working now. My post probably hasn't helped you get you where you want to go but it may help you to be content with what you have or may consider flashing an international rom minus modem and see if that helps.

From I walk into building calls and signal dropped dead . It truly sucks. I'm switching back to tmobile as soon as this month is over . I hate paying that extra 30 dollars but a phone is no good in one room .

I as well am on Straight Talk At&t micro sim and I get pretty decent speeds I believe Straight Talk cap's their LTE speeds at 15 down and I think around 8-9 up which ain't bad for the Chicago area. But there are times where I barely get 2 down and 4 up. I also have a Tmobile Note 3 stock/rooted using a ST sim.

Tmobile Note 3 on ATT Network
I have a Tmobile unlocked phone on ATT and I can't find out anyway to speed up the LTE. I get LTE it seems, but it cuts the speed in half compared to my girlfriend ATT variant Note 3. I tried to flash an AT&T modem to it, but then it would soft brick the device and wouldn't boot. I have tried every APN I can think of, but still no success. I have tried the build.prop, like adding the lines for faster data tweak, but still nothing is getting better. I have full bars, but speed is slow. Do you have any suggestions on what to do, b/c I am out of options. Thanks.

Add me to the list. Just switched over to AT&T from T-mobile, but get very bad speeds. The only reason why I switched over was because with T-mobile, I was getting poor quality signal almost EVERYWHERE, so I had no choice.
I'm curious; if the bands in our phones support the proper AT&T bands and we actually get LTE, it's gotta be a software issue. Modem most likely.

Yeah im sure it has to do with the way the modem is optimized for ATT's 1700 band. I'm also in the same boat and have flashed ATT's modem but it doesn't work. Others have flashed ATT modems but I dont think anyone has been able to successfully see their baseband change in the settings so no one can say whether it worked for sure. I can tell you that the bars have nothing to do with your call signal though, its just your LTE signal strength. If you really want higher signal in your house if LTE seems to drop or be super slow, you should manually switch over to use HSPA+ in your house. Its a pain...i know.
I'm hoping eventually the newer modems fix the 1700 mhz frequency optimization or some devs figure out how to successfully flash N900A modems on the N900T.

LTE speeds
I have great signal almost always it seems like. I have full bars on LTE or 4G/HSPA+, but if I put my sim card in my AT&T variant note I get at least twice as much throughput than with the note 3 tmobile. It has to be a software issue, I have tried to flash att modems with no success. Just got to wait for a tweaked modem. I have even tried tweaking build.prop file and it works a little bit but not much. It is just weird I have full bars with LTE, but I won't be able to get data sometimes, which is really weird. I think there has to be something with the signal bars showing higher dbm that it actually is receiving. Probably another software glitch. Well if anyone has any insight on this issue let us know, please been looking everywhere.

LTE speeds
I think also that the modem is not the only issue. I flashed a kernel today after being on the stock kernel on the T-Mobile and I did a speedtest and the speeds were really low. Flashed another kernel and boom faster speeds back to where I was, maybe higher, but I will monitor to see what happens. But I read that Kernels do affect data speeds sometimes. I am just going to keep looking around to see if any kernels work.

Is there any tweaks that can be done to kinda help the LTE or at least fix my signal bars showing full all the time. I am thinking it is not switching towers when it is supposed to and giving a false signal strength. Is there anything on modifying like you can on Sprint phones with dbm on wimax, where it will switch antennas.

I upgraded the modem and bootloader to the new NE6 version. I'm on Temasek CM11. My observations:
Signal strength is slightly better. Speeds are definitely much better. Prior to the upgrade, I'd get around 6-15/down, 3/up. Now I consistently get 25/down, 10/up.

How did you get the new modem to stick? Did you do the triangle away method? If so, did you have to revert to a stock kernel first? I'm trying to upgrade only the modem and leave the bootloader as is. Is that a bad idea?
