T-Mobile - horrible reception? (Time without a signal)

I've got the T-Mobile SGS3, and am getting horrible reception.. time without a signal hovers around 30% at home on this phone, where as both my Nexus One and Sensation had no problems whatsoever with signal. Going for WCDMA preferred instead of GSM auto (default out of the box setting) didn't help.. fwiw, I'm getting 3-4 bars of signal on the statusbar.
is anyone else having this issue, or is my phone just a lemon?
Thanks!

bump.. no one else is seeing bad reception?

I think a lot of people are having this problem in one way or another, including myself.

Im on sprint, and my signal is piss poor also. Take forever to logon to pandora and forget about watching any videos, impossible. I'm thinking the modern needs an update. What's the sense in having this bad ass phone if we can't even listen to internet radio in peace. I'm going back to my SSG2, and getting my HBO back for lunch

I'm still getting 25-30% time without a signal, just sitting at home.. why is the signal strength for the SGS3 so bad?! Is it a Samsung issue? I've only had HTC android phones before this one.

Note 2 lte firmware help N7105

Hey folks what firmware did your sim free UK only please lte note 2 come with and three UK customers also.
Having some troubles here if I'm browsing the Web and my signal icon is H+ everything fine but if it drops to H/3G my data just crashes, tried a few different radios so far but still same thing happening wanna try all possibilities before having to send back really, this is what I got so far and you can see my speeds are insane but it's just annoying now.

The phone will drop to 3G to conserve battery when data is not in use. I believe there's a way to force HSPA only, you're going to have to search for it. Your phone and its radio firmware are fine though.

Currently on giffgaff and was thinking about switching to Three to take advantage of DC-HSDPA and eventually 4G, but it's worrying if the data connection is that flakey.
Sorry I can't offer any help but will be keeping a close eye on this thread and hopefully will give some insight about the Three network. The lack of 2G fallback for calls also bothers me.

I understand it will drop when not in use but this is when I'm on a website browsing it will drop and If I click a link it won't do anything it's weird

4.1.1 7105 on t-mobile does not do that, works fine.

I'm having okay data connection using the modem in your screenshot. N7105 on Three.
3G H H+ all working fine but there are some dark spots where I can't get data even with H+ on full strength.

That is what you can expect from T-Mobile service. Its the reason I left.

This does not seem like a phone/software issue, but more of a carrier issue.
it is also worth noting to make sure that the phone is in fact completely sim unlocked (or else you wont get the correct bands for your radio), although I would not expect you to get service if it was not unlocked.
I am not sure if there is a different radio file for the GSM version of the device.
Anyone else have knowledge on the radio files?

Ive posted screenshots of my apn an connection thru signal checker. I know some phones are one lte 4g all day. I would love to figure this out. I am unrooted with no mods at all.

Tmobile uses 3 LTE Bands.
1900 - Phone supports it
1700 - NO PHONE SUPPORT
700 - Phone supports it
it is very possible that the area you are in is mostly 1700, and the phone is hopping around to find a strong signal.
~~~~~
Actually, from this page,
http://www.phonearena.com/news/Chea...on-T-Mobile-and-Sprint-use-in-the-USA_id77933
It shows that the 1700 band is one of tmobile's primary LTE Bands

Yes i saw that as well. But is there a way set band priorty or change the priorty settings??
Sent from my SM-G920P using XDA-Developers mobile app

That is a good question, which I do not know the answer to. I would imagine that the settings for that are in the carrier settings, which get downloaded when your phone connects to their network.
as for changing that, your guess is as good as mine

Best AT&T Radio / Modem

I am on AT&T and currently Viper ROM ... I have pretty much been a little disappointed in the overall cellular reception of my HTC10 since I got it (compared to my Nexus 6 - which I wasn't thrilled with it's reception -- but the HTC10 is worse!) The N6 reception was pretty modem or radio dependant.
I'm currently on the 1.53 firmware --- has anyone else had a better experience in a different radio or modem (on AT&T) ?
Does the 1.55 ROM have a different firmware and especially radio ??

I am on stock 1.53, use AT&T and have no complaints about service at all. It has been better than my S6 Active was.
Until people start a radio collection (They always have), you are kind stuck with whatever ones come with the ROMs. When they start posting them, then you can flash away until you find one that works better for you.

I guess, more importantly than the Rom, what is your baseband?
I know I live in a somewhat remote area but 90% of the time I've got good LTE service. But I have about a fifteen minute stretch of road that I drive where reception is really marginal (I even have a signal booster and external antenna for my car)
Pretty much most of this area with my HTC I have no service, where I rarely lost completely with the N6

This is my baseband. Stock 1.53 on unlocked US edition.
Area does play a big part. In Phoenix, I haven't had any issues.

Thanks
With that said, thinking that I had flashed both bootloader and radio to 1.53, I looked here (see screenshot) and saw this number for my baseband..... The same number was listed in the download mode info screen (along with 1.53.....OS)
What do you have?

I am not having any issues like that on T-Mobile US. I just got the phone a week ago. I did have to go and change APN settings as well as enable VoLTE. I did have to call T-Mobile and they did a refresh of the device on the network. Call quality has been great and speeds have gotten over 80Mbps down with almost 30Mbps up. Check and use the T-Mobile US LTE IPv6 APN. Do you have any other T-Mobile devices near where this is occurring?
