DC-HSPA+ on 1900 is beginning to show up in some markets (notably Chicago) where AWS spectrum is scarce and PCS is plentiful.
[Galaxy S 4 Developer Discussion [Developers-Only]] Product F(RED):
That's odd. I always though DC-HSPA+ was possible because AWS is a combination of 2 (hence the Dual Carrier/Channel) frequencies. It'll take a long time, but I can't wait until this is done country wide. Tired of being limited to T-Mobile devices if I want AWS HSPA+. Where I live is refarmed and has LTE, but my campus for example isn't and also doesn't have LTE coverage.
[Galaxy S 4 Developer Discussion [Developers-Only]] Alttwo:
I got T-Mobile LTE on my Verizon s4 i545 today. 2 speed tests 2 different times 2 different places. Detroit metro
[Galaxy S 4 Developer Discussion [Developers-Only]] lynyrd65:
Here's how FDD spectrum works.

There is a separate downlink spectrum band and a separate up link Spectrum band.

For AWS, 1700-1790ish mhz is the up link band and 2100-2190ish mhz is the downlink band

For PCS, 1900-1950 is the uplink band

And 1950-2000 is the downlink band

(I fudged the actual frequencies a bit but you can see the point)

For all FDD spectrum bands, (which is all T-Mobile and Vzw use), there is an uplink band and a downlink band.

DC-HSPA+ is dual carrier HSDPA which is to say it pairs two downlink carriers of HSPA to get double the speed.

Each HSPA or GSM carrier takes up 5mhz uplink and 5mhz downlink.

So if T-Mobile has 15mhz downlink and 15mhz uplink available to use in a market they can run 2 HSPA carriers and 1 GSM carrier.

Can u walk me through how u get "LTE" working on t-mobile?

Im on hyperdrive 10.2 with MJ7 baseband.
[Galaxy S 4 Developer Discussion [Developers-Only]] Alttwo:
Once you have the T-Mobile lte APN setup, it should connect automatically
[Galaxy S 4 Developer Discussion [Developers-Only]] Product F(RED):
There's no hacking/rooting required to get T-Mobile LTE working on Verizon devices:

- All AT&T LTE devices support T-Mobile LTE

- All T-Mobile LTE devices (obviously) support T-Mobile LTE

- All Verizon LTE devices from the Galaxy S4 onwards support T-Mobile LTE (but may need an update to enable it)

However if you're using an AT&T or Verizon device and you're not in an area that has 1900 MHz (refarmed) HSPA+ ("4G"), you'll bounce between EDGE and LTE. Though most LTE areas are refarmed.

Do this phone model need to be unlocked if I'm buying from Swappa? I'm thinking to cancel my contract with sprint and buy a verizon device to activate on t-mobile.. I am a total noob here..

[Galaxy S 4 Developer Discussion [Developers-Only]] Product F(RED):
All Verizon devices starting with the iPhone 5 (basically any LTE device) is factory unlocked.
[Galaxy S 4 Developer Discussion [Developers-Only]] justda:
Every Verizon LTE device is 100% SIM unlocked.

They are SIM unlocked for LTE use. The US is the only country that uses Verizon's LTE Band, so while that LTE unlocked sounds nice it is kind of pointless. All of the phones that have working GSM radios are also GSM unlocked for use ""outside of the U.S."" but with the APN information they will work in the states.

This was done in part because Verizon is required to have unlocked devices due to the agreement that was in place when they purchased some of their LTE spectrum. Also why T-Mobile gets to play piggy back on the 1900 band of LTE.

Verizon phones are still IMEI locked, Verizon can shut your phone off if you don't pay your bill or leave your contract early without paying the fee's but only If you are using it as a verizon prepaid phone, or if you were to buy a Verizon phone off craigslist or whatever and try to use it on your verizon account. If you use AT&T or T-mobile they cant do anything to you because they don't have access to your phone through the sim.
[Galaxy S 4 Developer Discussion [Developers-Only]] Product F(RED):
You're right in some places and wrong in a lot of others. I've worked for Verizon and Sprint, and am generally pretty knowledgeable in the area of cell phones.

Factory unlocked means SIM unlocked from the factory. Same thing.

They're SIM unlocked, period. They'll work on CDMA (authenticated with the LTE SIM card), LTE, GSM, EDGE, HSPA+, and LTE. No features are locked down. There are certain phones that, like you said, have the APN menu disabled or hidden, but are perfectly usable with root and/or a custom ROM (e.g. Galaxy Note 2). The Galaxy S4 and later support AWS (1700/2100 MHz) LTE, which is what T-Mobile uses for LTE, and what every Canadian carrier that has LTE uses (e.g. Rogers). So no, not totally useless. On T-Mobile you would get EDGE, refarmed HSPA+, and LTE. If you took it to Canada, it would work perfectly on Rogers, for example, which uses 850/1900 MHz HSPA+ (same as AT&T) and AWS LTE (same as T-Mobile). On AT&T it would get EDGE and HSPA+.

Yes and no. The FCC approved Verizon's 700 MHz Upper-C Block spectrum usage (really more like 750 MHz) under (one of many) conditions being that they leave their LTE devices SIM unlocked. This is why, for example, the iPhone 4S won't work in the US due to rejecting US SIM cards. It has no LTE, so it's no obligated be fully unlocked. An iPhone 5, however is. Also some devices support LTE but don't have a GSM radio in them, such as the Verizon Galaxy Nexus.

T-Mobile doesn't use 1900 MHz for LTE. They use AWS (1700/2100 MHz). They use 1900 MHz for EDGE (2G), which they are refarming to HSPA+ (3G, aka "4G"). Currently, most of their "4G" is AWS, but since that's what LTE uses, they want to use most of the EDGE frequency for 4G, and most of the 4G frequency for LTE.

The MEID/ESN can be blacklisted, true. But that only affects usage on Verizon. You can easily buy a blacklisted iPhone 5, or Galaxy S4, or HTC One, and use it on any GSM carrier. The CDMA blacklist doesn't apply to GSM carriers and vice versa. They cannot "shut your phone off." They can blacklist it so it can't be used on their network, or they can turn off your service. That's all.

[Galaxy S 4 Developer Discussion [Developers-Only]] dcacklam:
Verizon started releasing 'world phones' with both CDMA and GSM voice support a few years back... Like the 'Droid Global'...

The S4 (and many of their other phones now) is such a phone, and it will work on GSM networks with a GSM SIM, if properly configured...

The issue is that LTE is more carrier-specific in terms of what radio-frequencies each carrier has licensed, and many phones LTE support will only work on the LTE bands that the selling carrier owns...

Guys, not sure if anyone verified, but i was able to find all bands and change them, on MJ7 with the Service Menu:

Here are the steps:

Goto phone dailer, and enter *#27663368378# for the debug service menu.

In "ServiceMode", select [1] UMTS

In "UMTS MAIN MENU", select [1] DEBUG SCREEN

In "DEBUG SCREEN", select [6] PHONE CONTROL

In "PHONE CONTROL", select [7] NETWORK CONTROL

In "NETWORK CONTROL", select [2] BAND SELECTION

Here under [4]LTE BAND PREFERENCE you can change the band.
[Galaxy S 4 Developer Discussion [Developers-Only]] dennis5pia:
I guess that's a default menu. I remember I entered that menu on a galaxy exhibit II, that phone doesn't support WCDMA 900, but in that menu WCDMA 900 was listed, so I tried with a WCDMA 900 carrier sim card and set that band and got no signal.

So not all bands listed in that menu are supported.

Verizon Galaxy S3 with T-Mobile SIM card, Data only "E"???? Why??

I have Verizon wireless galaxy s3 and it is completely flashed with "Omni" ROM. Today, I switched from Verizon service to T-mobile service. It is working with Calls, But data always in "E" edge network. How can I get LTE or 4G network on Verizon galaxy s3 with T-Mobile SIM card?

I think I have right APN settings?
[Galaxy S 4 Developer Discussion [Developers-Only]] Product F(RED):
You can't. The Verizon Galaxy S3 only has 900/2100 HSPA+ (3G/"4G") and only supports Band 13 LTE (T-Mobile is Band 4). Nothing you can do about it. The Verizon S3 is useless on any other network in North America.
[Galaxy S 4 Developer Discussion [Developers-Only]] spirodave:
Yeah alot of times it will show a band that doesnt exist in the menu.. Most likely because the phone shares a device tree with another phone that does have that band .. On my tmobile GS2 i had it showed LTE bands in the menu because it shared a device tree with the very similiar Att SkyRocket LTE

---------- Post added at 06:33 PM ---------- Previous post was at 06:31 PM ----------

What might work is to turn on Data Roaming .. I unlocked my Att Gs4 and use it with Tmobile and the only way to get LTE to work was to turn Data Roaming onn.. Give it a try and let me know if it helps
[Galaxy S 4 Developer Discussion [Developers-Only]] Mystique:
Hspa+ is still very good.. Not sure about T-Mobile.. But HSPA+ is better than (vzw) 3G.. And some vzw LTE..
[Galaxy S 4 Developer Discussion [Developers-Only]] Product F(RED):
No. You don't understand. The Verizon S3, unlike the Verizon S4 and newer, PHYSICALLY (on a hardware level) does not support AT&T or T-Mobile's bands beyond EDGE. There's nothing he can do about it.

It only does 900/2100 3G ("4G") and 700-C LTE (Band 13).

AT&T uses 850/1900 MHz for 3G and 700-B / 1700+2100 for LTE (Band 17 and Band 4)

T-Mobile uses 1700+2100 / 1900 for 3G and 1700+2100 LTE (Band 4).

There's absolutely no way around it. It's the phone itself. He has to get himself a Verizon S4 or newer or any AT&T or T-Mobile LTE device.

Yes flash a custom recovery (cwm etc) and backup from within there. If you ever need to reinstall, restore it also from cwm recovery and flash stock recovery and that's it. Burn to fully stock.
[Galaxy S 4 Q&A, Help & Troubleshooting] marc_ecko28:
I think yes.. you can back up.. (maybe Im not sure with this one)

But before restoring your back up from stock and you are coming from aokp make sure that you flash first stock rom in odin to avoid problems..
[Galaxy S 4 Q&A, Help & Troubleshooting] ultramag69:
The answer is No, you can't back up your stock unrooted rom.

You can however root it, install a custom recovery and backup the rooted rom on your phone. You will need to check if it was backed up on your internal drive 1st before flashing as you will loose it if you wipe the data on your phone.

You can also go to Sammobile.com and see if they have your rom there. Go to the firmware part then check your firmware at the top . It will ask you for you device (I9500) and country then give you the latest firmware available. You will need to register to download these roms...
[Galaxy S 4 Q&A, Help & Troubleshooting] sxi200:
You don't have to be rooted to flash / use a custom recovery. Therefore he can backup without rooting his device.

I did it myself before I rooted / customised my stock rom.

After rooting, I backup my stock rom to a external card before I start messing around. Just restore using CWM when u have a corrupted S4.

[Ubuntu Touch Apps and Games] 5m0k3:
I wanted to share a few screenshots highlighting the progress of the Ubuntu Blackjack app. The app has seen a number of significant improvements since I last provided an update here:

When I began, I intended to include several card games in one app, but somebody suggested that I focus on one game and try to make it really enjoyable to play. The idea was that the game would be the experience that other developers see and want to emulate. I heeded this advice, and focused on blackjack. Initially, the game was very simple. A deck was generated, and the player simply drew cards, but there was no real motivation to continue playing. I implemented additional gameplay features so the game would involve a fair amount of strategy, rather than sheer luck. Still, the game needed an objective, so I devised a system for keeping score, with increased stakes as the rounds progress. Naturally, I had to add a database to store the top 10 scores! Later, I realized it would be nice to share high scores with friends, so I utilized the Online Accounts and Friends APIs to allow sharing of scores on social media networks. Hopefully this publicity will draw more users to the Ubuntu Touch platform.

Next, I focused on audio/visual improvements. I incorporated feedback from the Ubuntu community, including an Ubuntu design clinic, to implement designs that are simple and functional, yet visually appealing. I included realistic animations and textures. It was important that the design be convergent so it will look good on all screen sizes and take advantage of the available screen real estate as it scales up. Consequently, blackjack is a great way to pass a few minutes on phone, tablet, or desktop! Next, I packaged a rich set of free audio and added a toggle to the settings page, so the user can choose to play with sound for a more immersive experience.

I want the user experience to be pleasant from start to finish, not just while the game is loaded. To balance all these new features, I had to make changes to improve load time. I also decided to add a splash screen, so the user has visual feedback while loading is in progress. A splash screen is much more pleasant to look at than a blank white screen.

Download the app today from the click store on your Ubuntu Touch device and let me know what can be improved!
