T-Mobile fits my needs, I live in suburban Atlanta, and I get really good data speeds. Have had NO issues with call drops. Customer support has been pretty good to me. My only issue is when I go some where rural. In those situations I get 2g or no bars. In my opinion, I'm satisfied with T-Mobile. I'm on a shared line with my brother and we pay 130 together for 1000 minute, unlimited text and unlimited data.

Edit: Added speed test photos

I switched from Verizon to T-Mobile 2 years ago and im loving it, much cheaper and the signal and data is just as good as verizon minus LTE is a tad faster but T-Mobile is selling a couple thousand towers and getting 4G LTE ones in 2013
[T-Mobile, Samsung Galaxy SIII] DroidOnRoids:
Damn. Just did research on data/signal coverage in the Grand Forks, ND area and sadly Tmobile has no coverage. All the other 3 carriers do. What a bummer. Guess I have to stick with VZW :(
[T-Mobile, Samsung Galaxy SIII] nnowak1103:
Yea T Mobile is not a widespread carrier compared to Verizon but if t mobile supports your area then its great
[T-Mobile, Samsung Galaxy SIII] TechieGeek:
It doesn't even matter if your internet connection is that great, the phone just wants a strong WiFi signal. A Wireless N router works well, and if you have a large property to cover you could purchase some repeaters to put around the house. As long as the phone has a strong WiFi connection you shouldn't have any problems with WiFi calling :)
[T-Mobile, Samsung Galaxy SIII] sleevasteve:
I just made the switch to Verizon after prob 15 years, and I honestly couldn't be happier. I still love T-Mobile for their customer service and I seemed to always have voice services no matter where I was, but I would definitely find myself in areas were I didn't get s*** for data services..which especially sucks if you're off the beaten path and trying to look for an address and/or navigate somewhere...not to mention you can kiss Facebook and xda goodbye in those areas as well(that is IF you run into places like that in your area). After testing in several locations, I've found that everywhere I would pretty much lose all data on T-Mobile(I'd be on Edge, which is pretty much dial-up), I have great 3G coverage now on Verizon, if not 4G LTE. If the network didn't make as much of a difference as it did in my surrounding areas, I'd still be with T-Mobile, no doubt.
[T-Mobile, Samsung Galaxy SIII] psykhotic:
I didn't want to thread Jack by replying to the other people but I have a 300mbps dual band N router and have full WiFi signal and WiFi calling still drops dozens of times a day. I think it may be because I have zero service in my house and for whatever reason it won't work without cell reception. I do notice that whenever it connects again after trying 3-4 times the location thing will pop on. I thought having GPS on helped.

It dropped service while typing this.......

I can sit on the router and it doesn't make a difference.
[T-Mobile, Samsung Galaxy SIII] Pennycake:
Well, if they do end up kicking you off eventually and you don't want to pay for your own Verizon contract, you could look at something like Straight Talk or Virgin Mobile. It's not a huge amount of full-speed data, but it's pretty cheap - just check out whose networks they run on and who has coverage in your area.

I wonder if it's because it keeps trying to connect and trying to switch back and forth ? Would it help to turn off mobile data ? I have zero cell signal (no bars, just the crossed-out circle) and no GPS signal, either, here in my basement - but it doesn't present a problem.

I wonder if it's the 911 issue ? I have my address registered on T-Mobile, so I think they use that if they can't otherwise determine my location.

[T-Mobile, Samsung Galaxy SIII] Orical:
I've been with T-Mobile since the beginning and I've never had a bad experience, I'm in Boston though so coverage is awesome but the customer service is part of the reason I won't go anywhere, Verizon laughed at me for asking about unlimited data which was so over priced to begin with but they might as well be Apple with the amount of control they demand over their services. T-Mobile is solid though, the people that complain about their customer service are usually the ones that are paying their bill late, I get awesome deals being a platinum customer.

Question

I have a couple questions regarding your switch, I hope you can help me out.

How easy was the switch from Verizon to T-Mobile?

Did you need to install new firmware from T-Mobile or just install their new sim card?

Were you rooted at the time and with a custom rom?

I have the Samsung Galaxy Note 2 and it is rooted with a custom rom ... I am worried if they try to install, my phone may brick.

Thank you in advance ... any help would be greatly appreciated!

[Nexus 10 Q&A, Help & Troubleshooting] orellius:
Hello!

Just curious if there is an issue with using my new Nexus 10 2A charger with other phones, such as my HTC Sensation or Blackberry Torch?

The Sensation uses a 1A charger, but I assume the phones are smart enough to only draw the current necessary, so they won't be damaged by drawing too much?

I'd like to just use the Nexus 10 charger and not have to carry other ones.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
yes it is fine
[Nexus 10 Q&A, Help & Troubleshooting] orellius:
Cool thanks
[Nexus 10 Q&A, Help & Troubleshooting] nutnub:
I heard though that

*first it creates unnecessary heat because the current drawn by circuitry on lower amperage device has to be dissipated as heat

*second, this is less science/engineering but someone said that the specific pins are created by companies and the pins themselves can vary in terms of impedance, thus change the overall circuitry of the device in the long run

*third Li-Ion can pull more current than the default charger and it tends to do so to charge faster, albeit at the cost of the battery overall life deteriorates because higher charging rates also leads to faster breakdown of cells?

I wish I had sources, but this is what I pulled off the Internet when I was younger... can you please assist and advise? Would greatly appreciate (even if we start new thread from this (:
[Nexus 10 Q&A, Help & Troubleshooting] orellius:
Wish I knew for sure too. REally I don't care a lot about my HTC Sensation as I plan on getting a Nexus 4 LTE when it eventually comes out. Hopefully those come with 2A chargers! :P

Sure I could get a Nexus 4 and use LTE right now on Bell, but I'd rather wait for an official one.
[Nexus 10 Q&A, Help & Troubleshooting] skally:
Everybody seems to misunderstand LiPo charging, as it is different than previous battery technologies

For general LiPo Information, you should look here. Charging information is about halfway down the page

[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
Ill quote the important part:

Pretty much all phones are right around 2000mAh capacity now days so even going by the "old" golden charging rule a 2A charger would be safe to use. My Galaxy Nexus came with (I think) a 1A charger, but ever since I got my tablet shortly thereafter I have just used the tablets 2A charger for both devices and never once had an issue. It has been 8 months now of using the 2A charger on my phone. Idle life can still reach a little over 3 days on a single charge and I still get one of the best screen on time's of most people I know around the forums. So yes from personal experience a 2A tablet charger is completely fine to use on a phone.
[Nexus 10 Q&A, Help & Troubleshooting] ShadowVlican:
Charging circuitry is built into the device, not the "charger"

Nothing to worry about
[Nexus 10 Q&A, Help & Troubleshooting] nutnub:
Is it safe to assume that all chargers come default at 1C charging for their device? Because if that's the case, I figure most electronics we own can just be replaced with 10w chargers (which would make life much more convenient).

This is slightly related/unrelated, but how do you know whether a charger is "high quality" or will only provide "constant current / constant voltage"? It seems strange to me that these days, you can't find the circuitry of many devices we own publicly available so you can't check if the design is good (let alone how they chose the components in their design?). Do you (and other veterans) have any thoughts on this?

Thanks for teaching me lots!

[Nexus 10 Q&A, Help & Troubleshooting] sonicfishcake:
I bought one of those 2amp double chargers from a seller on Amazon. It wasn't really cheap either (in cost anyway- I spent a bit more hoping it would be higher quality). After plugging in my MotoRAZR and the wife's lumia the charger popped and some plastic from the housing of the charger flew across the room! Thankfully both phones were fine.

I wondered whether both phones tried to pull more than the charger could handle and the charger had poor quality circuitry.

Since then, I've only ever bought branded official replacement chargers (Motorola, Samsung etc). I'd happily mix and match them to the phones but I'd be wary of buying a no name Chinese jobby from Ebay or Amazon marketplace.
[Nexus 10 Q&A, Help & Troubleshooting] skally:
Most batteries can discharge a lot faster than they can recharge, but with LiPo, the difference is getting smaller.

Batteries used to need trickle charging as if you charge fast they would get hot, which causes the chemicals inside to expand(think like a fizzy drink, pour it fast and it will overflow) causing the battery to burst, exposing nasty chemicals.

New technology means the charger can accurately monitor how fast we fill the battery, without letting it get too hot, and also the way it is filled(as with the fizzy drink, pour down the side of a glass rather than straight to the bottom and you will fill the glass faster, with less chance of it over-spilling)

Unfortunately, industry is full of products made to a budget, usually by using cheaper components/designs(the charger for the ASUS TF101 was renowned for failing), so there is no foolproof way of determining 'quality' apart from word of mouth, looking at quantities sold, feedback in reviews/forums.

Basically, it boils down to 'consumer testing'

Here's a bit more related information found buried deep in documents here: http://www.usb.org/developers/devclass_docs

The USB2.0 specifications for current output say the maximum current is limited to 1.8A, while USB3.0 has a maximum current limit of 5A

Hopefully, USB3.0 will quickly become a new standard for portable devices.
[Nexus 10 Q&A, Help & Troubleshooting] nutnub:
more questions!

First of all, let me please thank you for responding and being so thorough with your answers! There is so much information out there, and in my 22 years of existence, I cannot for the life of me sort through the sheer amount of data. I do greatly enjoy reading every little thing that is posted, especially in this thread because I think it's super important to understand the electronics that we interact with.

My concern with this is that if Motorola or Samsung does put out a product less than optimal, would we all know? Another way of asking this is how do we know that Apple/Motorola/Samsung/Lenovo does produce superior products and it's not merely a matter of advertisement or brand image? Do you think there is a way to know, as a consumer, that even third party products are becoming more competitive, given that smaller companies have much harder time advertising and building a name/brand for themselves? (if you can't tell, I am rooting for the little guys because I may one day work for the little guys)

Thank you for clarifying for us. Would you happen to know if there are specifics to recharge specs, short of finding me published papers on the technology? What you said is definitely what I've been reading from the Internet and I do trust you, just would help me have greater peace of mind with my nice and shiny devices,,,

A quick question, just because USB3.0 should allow up to 25W, that doesn't mean that it's the standard for devices, does it? As in Nexus 10 probably can only draw 10W, even if my computer (which although stated is USB3.0) may not have the circuitry behind it to allow for such a draw? I'm a little iffy on the whole implementation of USB standards. Because if USB2.0 has draw of up to 9W, I haven't seen this from my laptop or any devices claiming to have USB2.0 ports,,,

but then again, I may be paranoid. Just trying to line up my experience with theory!

Thank you all for so much support and enthusiasm. Any chance we'll see this on a top thread somewhere?
[Nexus 10 Q&A, Help & Troubleshooting] Olaeli:
If the Nexus kernel says the limit is 2A then that's it. It cant use more power.

Have you seen the internal USB 3.0 cable?

It's at least twice as thick as a USB 2.0 cable, I got a new chassi for my computer last week, with a couple 2.0 and a 3.0 USB front port.

And if your motherboard's built for USB 3.0, I'm pretty sure it can take the current. Otherwise there would be no meaning of adding 3.0 support.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
If something is listed as a USB3 port, it must be up to USB3 certifications. Otherwise the manufacturer of the device is liable for a huge lawsuit if issues arise. If something says USB3 that doesnt mean it IS drawing 25w though, just that the port is capable of having 25w pulled through it over the USB connector. Same with USB2 and its 9w limit on the spec. Also, plugging a tablet such as this into a computer's USB3 port does not mean it will charge faster or get faster data transfers, since the cable being used and the device are still of the older specification.
[Nexus 10 Q&A, Help & Troubleshooting] skally:
Have a look here for info on the recharging process for Lithium based cells.

https://sites.google.com/site/tjinguytech/charging-how-tos/the-charging-process

It is worth noting the level of precautions taken while charging the cells aggressively. You really don't need a bucket of sand on standby when you plug your phone in to it's charger;)

There are actually 2 different current limits for each USB specification: USB2.0 has 0.5A and 1.8A, while USB3.0 has 1.5A and 5.0A

The lower of the current limits is what I would expect to get from a USB port on a computer, while the higher one I would expect to get from a dedicated charger.

I believe the higher current specification was added purely for charging mobile devices, as it is only achieved by adding a resistance across D+ and D-, removing the data transmission capabilities of the port. I don't know if that's practical, or possible with a computer USB port.

I do remember seeing motherboards with ports specifically designed for fast charging, but I haven't got any info on them as yet.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
There are also kernels which enable "fast charging" on a PC. Basically it removes the data connection in software and treats any USB connection as if it were plugged into AC. You can charge just as fast on a computer as you can on a wall charger when this feature is enabled in the kernel.

I am using the N10 charger for my Note 2 and it charges bloody fast using this charger. Charging is noticeably faster on Note 2 than the stock 1A charger that came with the Note.

Battery is not getting warm and battery temps are similar to those on 1A charger. Basically its cutting the charging time in almost half.

Agreed. Note 2 charger is awesome. Bought a powergen 3.1 amp car charger for the note 2 also after watching videos and reading up on proper car chargers for the phone. Guess I can use it for my nexus 10 too.
[Nexus 10 Q&A, Help & Troubleshooting] aznmode:
I own RC cars with lipo batteries and rule of thumb is total mah divide by 1000 = the Max amp charger you can use. So a 2100mah battery can be charged with a 2.1A charger.

[Galaxy S III General] KarimSalloum:
Hello,

The battery on my S3 is driving me crazy. I originally had an S3 and went to the Note II, but reverted back to another S3 because I couldn't stand the size of the Note. Anyway, this S3's battery is really bad - I barely use it and it drains 5% an hour, sometimes more. I've tried everything, location is turned off, social media is all turned off I just update it manually... I've attached some screenshots. it was 50% and dropped to 34% in just 2 hours and a half, I only used it for 2 minutes during that time according to the Screen data.

Any thoughts, suggestions or miracle solutions are appreciated.

Try this. Im using Sotmax as well but with perseus kernel. In stweaks I under volted the CPU by -75mv and gpu by -50mv. Super smooth and completely stable.

I tried other kernels and I just couldn't get good battery life. I'm getting about 14 hours of solid use. Screen on of about 3.5 hours. I used to only get 7-8 hours.

The other thing I did was freeze the following which constantly run in background.

Video Hub

Software Update

SSuggest

Samsung Push Service (for Sammy app updates)

Make sure you remove your Samsung account. It constantly runs in background.

Wifi advanced settings change Wifi policy to only when charging. I find Wifi drains this phone fast.

I highly recommend resetting the battery levels by typing *#0228#

Then choose quick start. Unlock the phone and your battery will show the actual levels. Charge to 100%

Finally, I matched the ril with the modem included with this rom. Install the app getril and download the proper ril and install.

Hope this helps!

Hi I have made this Tasker app for controlling the roaming pattern of my phone. It is based on Tasker. You can get the trial version from the play store.

It basically checks whether the cell ID shows roaming as on. Then it turns on the aeroplane mode. The checks are based on three loops while in aeroplane mode during roaming:

1) Checks every 10 min. for the first 20 minutes.

2) Checks every 15 min. for the next 40 minutes.

3) Check every 30 min. after 1 hr. (means you are away for long)

It will be helpful to those who don't have sufficient coverage of their carrier in either work/ school. It prevent the phone from going into roaming, it rather goes into aeroplane mode to prevent extra charges. You can also change the variable for these loops suiting your needs.

Import this project directly in your tasker. Nothing is needed just enable the profiles.

Let me know if anything else is needed, I would try my best to help ;) If it helps you hit the thanks button :good:

[Android Apps and Games] lionel_messi1:
I don't think there is a way to lookup the cell_id with some database online (if there is any). To stop the GPS from draining the battery, you can make a profile which enables the GPS at intervals of around 1hr where it will turn it on, get the location and turn it off. Thats the best solution that comes to my mind :good:
