[Motorola Photon 4G] daddymikey1975:
although i wonder if it keeps the phone from deep sleeping to keep the capacitive soft touch buttons 'awake' to detect the swyping motion..

just curious
[Motorola Photon 4G] KTT16:
Good point...i wonder if that will drain battery faster..definitely a cool mood though
[G2 and Desire Z General] noneedforvtec:
Hey guys and girls,

I own a HTC Desire Z, which works pretty well (at least the SMS application doesn't lock up like on my Donut-powered Magic), except when I make a call, the person on the other end doesn't hear me, unless I'm shouting directly into the microphone.

I originally thought it was the microphone, but the same thing happened with a wired headset. I've tried wiping the data and calibrating the microphone, but it fix the problem

One of my friends got it working properly last night by muting and unmuting the handset, but it stopped working after about 12 hours, and the muting/unmuting trick didn't work.

Unfortunately, my warranty has expired, and would be void anyway, because I replaced the front panel a few months ago.

Does anyone know what the problem is, or even better, how to fix it?

Thank you.
[G2 and Desire Z General] noneedforvtec:
Can anyone help?
[G2 and Desire Z General] xT4Z1N4TRx:
Try flashing a different Rom?
[G2 and Desire Z General] noneedforvtec:
I tried it with CM7, but it didn't do anything at all.
[HD2 General] nushuth:
Hi all!

i just have this problem:

i'm in italy with an operator called "TIM". you can call the service support by number "119".

i'm using radio version 2.15.50.14 from TMOUS device, in order to enable 576MB ram and magldr/android.

if i try to call my service support "119" the phone start an "emergency call" to another number, "112" wich is our universal emergency number.

anyone with same problem? i think this problem was concerned to radio firmware, but i'm not sure...
[HD2 General] samsamuel:
More likely to be the rom than the radio.
[HD2 General] nushuth:
i have same problem with different ROM, WP7 and android, android MIUI, android with SENSE; android CM7, gingerbread base and froyo base.
[HTC Vivid, Raider, Velocity] brucegil:
Now Asking the Second Part of the Question

Thanks for the expanded explanation. Now to the second part of the question:

Why do some people have great speeds and other people have poor speeds?

Here are some reasons I have tried to glean from the posts here. Please add, correct or clarify as needed.

1. LTE or lack thereof - Obviously only a few people have it now.

2. HSPA+ or lack thereof - The enhanced features of AT&T's 3G may not be in all places.

3. Bandwidth or lack thereof - I saw an article (sorry for no URL) noting that AT&T has more and better capacity in some cities than it does in others. This discrepancy between cities seems to be less of a problem for Verizon.

4. Load on the system - All those iPhones eating up what bandwidth there is.

5. Location - If you live in a hilly area like I do, there are going to be holes. Also, when I moved from a top floor office with a window to a 1st floor interior office (no, it was not a demotion), my phone service dropped.

6. AT&T System issues - Not sure what these might be, but a few posts have alluded to such.

7. Phone hardware and firmware - A couple of reviews I read noted that performance for the Vivid was somewhat less than other phones with the same or similar processor.
[HTC Vivid, Raider, Velocity] ClippinWings:
Great post!

and no worries, I just reformatted the list I got from your original post ;)

(I totally would have forgot UMTS lol)

Teamwork!
[HTC Vivid, Raider, Velocity] travisxcore:
From what I've read up, 4G qualifies for up to 56mps down (thats no load, perfect signal) and is just an upgrade to the Hspa+ protocol. I believe the reason AT&T doesn't show 3G, 3G+, and 4G as different symbols is because they believe it would 1. Confuse the mass population and 2. The mass population would be outraged wondering why if they have a 4G phone it was only picking up 3G (people not understanding the work and money involved in upgrading towers and such). I've heard people complaining about not ever picking up LTE around here and I just facepalm myself so hard considering Charlotte isn't supposed to get it till the 20th and even then we still wouldn't get it here out in bfe.

Good article though, I'm sure the clarification will help some of the newer people here.
[HTC Vivid, Raider, Velocity] mariol90:
all phones will probably end up using one radio after the next gen LTE phones come out: http://www.anandtech.com/show/5118/qualcomm-announces-a-bunch-of-krait-based-snapdragon-s4-socs

this includes CDMA-based phones.

also, the thunderbolt and rezound allow simultaneous voice and data when on 3G, i believe it's because of the way the radios are set up in those phones.

definitely a great post. it's too bad marketing took over the meaning of all the "4G" terms. thanks, t-mobile.
[HTC Vivid, Raider, Velocity] Aus_Azn:
I hope someone makes a ROM that fixes the service bar so that it shows "3G", "H", "H+" and "LTE" properly. That's a total farce.
[HTC Vivid, Raider, Velocity] travisxcore:
Most cooked Roms have it like that although I know on like winmo and wp7 there was regedit to do it.

[HTC Vivid, Raider, Velocity] vhjc:
This is a question for Canadian people or people that owns a Raider version:

Do you have actually seen the H+ icon when you are on a HSPA+ network?

Or is it just showing the H icon but you know you are on a HSPA+ network because of the speed?

This is because my network operator claims to be HSPA+ but I can't see the H+ icon only the H one.

My speed on speedtest app is about 6Mbps/3Mbps. Is this HSPA+ speed?

Thanks for your answers.

Cheers!!!
[HTC Vivid, Raider, Velocity] dizzyraider:
Can't speak for the Raider people but from your speed it looks like you do have HSPA+
[T-Mobile LG G2x] substanceneil:
Is anyone else having issues with their Wifi-Calling on T-mobile?

I find that the wifi-calling app gets stuck at the stage there the app reads: "Enabling..."

* This is on either stock unrooted GB ROM or Xboarder's tweaked GB.

* Happening on two different routers in two different homes, different ISPs. Both

were working previously.

* I noticed this recently upon returned home from a long trip. During the trip, I had good cell coverage and didn't need the wifi-calling function anyway.

* T-mobile CSR reports an outage:

_Irina M: Ok, we are experiencing an issue with the G2X not able to establish a WIFI connection.

_Irina M: I will post the outage for you.

_Irina M: EFFECTIVE DATE: 11/7/11 OUTAGE TYPE: UMA...................................

MARKET AFFECTED: All

...................................

CUSTOMER IMPACT: G2X Cannot Activate Wifi Calling

T-Mobile subscribers may be reporting issues with the G2X encountering errors when attempting to activate Wifi calling. The device may show "enabling" but never connects.

Please Note: This issue is pending a software update but until this is released customers can upgrade to an UICC SIM card to resolve this issue.

MARKET/SERVICE IMPACTS TO: Global / Wifi Calling

CAUSE: n/a

* Despite this answer from t-mobile, I think it might be related to my recent change of a SIM card. I was having another unrelated issue and CS suggested I get a new SIM. The new SIM did not solve my issue. But now I have a new one. I did get a new SIM today, but this did not solve my problem. For the life of me, I cannot find my old SIM to reactivate.

Any one having the same issue? Can anyone test their phones to see what is what? Thanks.

11/18/11... I tested using a sim card from an Sgs4g with working 4g and wifi-calling. With this SIM in my g2x, wifi-calling was working again. It appears to me that my newer SIM cards x 2 break wifi calling.

If only I had my old card. Ironic that there was nothing wrong with that card in the first place.
[T-Mobile LG G2x] Reallist:
I don't use wifi calling but my wifi does cut out and stop working randomly. Right now I'm only showing one bar even though I'm Lees than 10 ft from my router. This phone seems to have random wifi issues and I remember reading something online conforming it, but I don't remember where.

Sent from my G2X
[T-Mobile LG G2x] wmm:
I have that problem (stuck at "enabling") a couple of times a month. I generally take that as an indication that it's time for a reboot, and so far a reboot has always fixed the problem for me.
[T-Mobile LG G2x] player911:
No I'm experiencing it too. It was working last night I know (at home) and it was working this morning.

My GF just called me at work, which was odd... and this makes sense. My WiFi Calling is stuck at "Enabling" also.

Tmobile has gotten rid of WiFi Calling on the newer phones because they are moving to a "new" standard. The new standard requires a new SIM card. WiFi Tethering is also not working out of the box.

Something is strange.

I even went into Apps and did a Force Stop and cleared cache and tried to launch it again... it just closes and never enables.

*UPDATE*

Now its working.
[T-Mobile LG G2x] matrix0886:
I never have connection problems, but the sound quality is terrible. The person on the other end sounds real robotic and choppy. It was like this even on my blackberry.
[T-Mobile LG G2x] player911:
Now its saying invalid SIM. Sweet.

[T-Mobile LG G2x] garrychau:
No problem here just try it one minute ago.
[T-Mobile LG G2x] substanceneil:
See my update above. I think T-Mobile has changed the sim cards but not yet updated the software. If anyone is using wifi calling, then hold on to your cards until they fix this.
[T-Mobile LG G2x] jcbofkc:
I have never used it but decided to test it because of this thread. Works great on weapon 3.0.
[T-Mobile LG G2x] player911:
I bought an old sim card off eBay but haven't activated. May try it out. I'm on CM7 and it hasn't worked in days.

I am using an old similar card, wifi calling working fine, but I can't use Bluetooth.

Nightly 199, faux cm kernel.
[T-Mobile LG G2x] JaiaV:
Bluetooth and Wi-Fi calling should not be affected by your SIM card in any way on the G2x.
[T-Mobile LG G2x] Ninosmaxima:
You need a gsa sim. These sim cards are made in the usa. Yea America!!!! **** yeah.

No but on some real talk the sim cards made in America are good quality.

India, China, and Mexico made ones do not support wifi calling. Plus they go out every month
[T-Mobile LG G2x] Ninosmaxima:
Gba sim*** check your apn settings. Or try clearing the wifi calling app data
[T-Mobile LG G2x] substanceneil:
I swapped my wife's sim card (about one year old) with my newer one. I asked customer care to reprogram our phone numbers. Either card supports wifi calling in the Galaxy S 4g. The old card supports wifi calling in my g2x.

When I get to an area of known good coverage, I will run a speedtest to see if I lose any speed using the older card.
[T-Mobile LG G2x] alpharetta:
Where and how to find old simcard?

I called Tmobile service yesterday. 3 different rep told me that I need newer sim which support 4G and wifi calling and offered to upgrade the new sim card for 20 bucks. I got mad and asked to talk with mananger. Finally a tech rep honestly told me that there is issue with wifi calling for G2X and their engineers are working on the fix, but no date of completion yet.

She sent me to a tmobile store to get a new sim card, and said it might solve the problem, but not sure 100%.

I went to the store, change new sim card at no charge. but the wifi calling still not working.

now, I saw people put the comment in this forum that we need old sim card. How do I indenfify the old sim card? what number? or serial number ect???

Can I get it from ebay?

Thanks

Alpharetta.
[T-Mobile LG G2x] e4e5nf3nc6:
The newer SIM will say TM9073. You gotta take it out and look at it.
[T-Mobile LG G2x] alpharetta:
OK.. I resolved the problem. I had TM9073 and it did not work with MUI ROM.. so I changed to newer sim card TM9102, and it still not work for wifi calling. I then read about the issue with MUI ROM. the wifi calling only work with CM7 ROM. So I reflash G2x with CM7, and still use TM9102 sim..

It takes 5 minutes to enable the wifi calling feature.. but it works now... so first thing first.. you need to make sure you have the correct ROM... and then sim.
[T-Mobile LG G2x] rew106ia:
Wifi calling on MIUI has only worked for me 3 times. That was on the first boot. I had the newer sim card. Just recently bought a older sim card and now wifi calling works for MIUI every time!!
[T-Mobile LG G2x] GTWalling:
It is the TM9073 Sim that is working properly on all other roms. The TM9102 is the Sim having problems with WiFi.

Same Cpu, resolution, screen and ram!!!
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
For one a stock Hercules usually runs around 3,200+ in quadrants. Secondly quadrant scores are never consistent. If the scores you've posted above were consistent numbers based on both the Skyrocket and Hercules then I'd say that the Skyrocket's software is more optimized than ours, which I don't believe that it is.
[T-Mobile Samsung Galaxy S II SGH-T989] jasonqw1:
When i just bought the phone i tested for like 3-4 times and the results range from 2300-2700...
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
I remember mines doing 3,200+ in quadrant on stock non rooted rom. Every user will have a different number. Check YouTube videos and you will see different numbers in Quadrant. Quadrant is always to be taken with a grain of salt. It is fun to see those numbers, but what do those numbers actually mean? It does not translate into what your actually day to day performance will be. I've never played with the Skyrocket but I can bet my last dollar that the performance will be the same as what we have now, unless Samsung optimized the software a little more on that phone vs ours. The Quadrant numbers are very similar to what I've seen on the Hercules.
[T-Mobile Samsung Galaxy S II SGH-T989] movieaddict:
Quadrants don't mean anything anyway
[T-Mobile Samsung Galaxy S II SGH-T989] TheSeanTeam:
Does having a phone with a higher quadrant score keep you warm at night? Does it make you smarter? Does it make you better looking? Will it make you more wealthy? Does it flex and tower and laugh at phones with lower scores? Do you cower and run from your friends with phones who's quadrant scores are higher than your phone's?

People seem way too focused on an irrelevant number that fluctuates quite a bit.

Is your phone smooth? Is it lag free? Can it play the newest and hottest games? How's the battery life?

I pitty (not to mention laugh at) those that feel like their phone is terrible if some number that doesn't really matter in real life performance isn't higher than the phone from their neighbors, the Joneses.
[T-Mobile Samsung Galaxy S II SGH-T989] ThC23:
Here you go, happy?

By the way stock numbers were between 3200-3600 for me.

[T-Mobile Samsung Galaxy S II SGH-T989] nitra:
Pull your SD card out and rerun Quadrant, run it 3-4 times in a row.

On my Telus S2x I hit 3800 usually after the 3rd test.

With the SD card in hits 2800~3100

Quadrant is a POS, it's not accurate with recent phones.

Check out Vellamo
[T-Mobile Samsung Galaxy S II SGH-T989] jasontx:
It was helpful with diagnosing an issue on an evo last night but the numbers don't mean anything. The guy didn't know how bad his problem was until he ran quadrant and saw how it performed. He removed his script and the performance was better.

It was fun for me to run the side by side with him to see the differences and he did end up calling me dirty names. :)
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
it's also possible the source code from the skyrocket might be more optimized than ours

remember the difference between the Telus version release of the source code vs Tmo version of the source release?

the Telus one was cleaner and optimized than the Tmo one.
[T-Mobile Samsung Galaxy S II SGH-T989] cashyftw:
Duh, its a sky rocket, what did you expect..
[T-Mobile Samsung Galaxy S II SGH-T989] kikiodead:
The question was why was there a difference when they have the same specs. Don't be rude :P Don't you feel this is a bit personalized and maybe a tad too much?
[T-Mobile Samsung Galaxy S II SGH-T989] Darmokk:
[Q]Tmobile Galaxy S II vs. AT&T Skyrocket Benchmarks: Whats up?

So the new Skyrocket from AT&T is basically just like our phones (same processor, screen size, ram, gpu, etc) but it has an LTE radio for AT&T's '4g' service.

So from what I would understand the phones, they should perform on benchmarks the same right? They even have the same android version number (2.3.5), BUT the skyrocket is killing it on benchmarks! Seemingly very superior to our phones, here is the engadget review

http://www.engadget.com/2011/11/11/samsung-galaxy-s-ii-skyrocket-review/

Anyone have any idea why there would be so much of a difference?
[T-Mobile Samsung Galaxy S II SGH-T989] jasonqw1:
Pathetic
[T-Mobile Samsung Galaxy S II SGH-T989] mbernusg:
Did u do your own quadrant?? Lol out of the box I was 500 points higher on the first try than what engadget posted.

Who cares man I love my phone!!!

Double post
[T-Mobile Samsung Galaxy S II SGH-T989] Enzopreme:
dude, not for nothing, bone stock i absolutely demolished all those scores listed for all the phones listed, i dunno if they got a bunk device, or what, but i think the phone is/does perform exactly the same.
[T-Mobile Samsung Galaxy S II SGH-T989] Darmokk:
Yeah i've done my own quadrant and my results are usually higher than what engagdet got but still not as high as the skyrocket.

I love my phone so this isn't a flame starter, but my friends skyrocket seems really fast and buttery smooth, whereas occasionally my phone has some very Slight lag.

I'm just curious if the skyrocket maybe has better optimization or something? Has to be software since the hardware is the same right?
[T-Mobile Samsung Galaxy S II SGH-T989] Killbynature:
Engadget is like the least reliable source sometimes the reviews are really biased. They have gotten better though. You would know this if you read the mytouch 4g review you'll think engadget hated anything that came from t-mobile. Quadrants don't mean much anyway.
[T-Mobile Samsung Galaxy S II SGH-T989] tigerz0202:
its obviously just a biased article toward the att version , i was getting 3700 on my stock scores, just ignore and be happy with your phone ,hell OC'ed ive gotten 4700 scores
[T-Mobile Samsung Galaxy S II SGH-T989] :
T-mobile has CiQ app that bogs down the system and performance on the stock rom. Let's not mention how much bloat is on the device.
[T-Mobile Samsung Galaxy S II SGH-T989] Darmokk:
This is more along the lines of what I was thinking, thanks. I am still on the stock rom, but I should have time to remedy that over thanksgiving vacation lol.

I hope after ditching the stock rom the Hercules will feel more like the Skyrocket, because it was BUTTERY smooth like the exynos Galaxy S II's are out of the box
[T-Mobile Samsung Galaxy S II SGH-T989] Darmokk:
Now it looks like people who have the skyrocket are using our custom ROMs as they seem to work lol. I read an article that said the Skyrocket is using a different snapdragon but I couldn't confirm that anywhere else. Does anyone know off hand if that's true or not?
[T-Mobile Samsung Galaxy S II SGH-T989] :
No the Qualcomm processor is the same as the amaze 4g etc. Just with Lte enabled radio.
[T-Mobile Samsung Galaxy S II SGH-T989] ryan562:
we all need to quit basing our phone's CPU performance on quadrant benchmarks alone.

my nexus s can hit the 4000s on quadrant at 1.5Ghz overclocked yet it feels laggy as hell v my sgs2 unrooted and out the box getting 2800-3000 on quadrant.

Sent from my T989 Samsung Galaxy S2
[T-Mobile Samsung Galaxy S II SGH-T989] killer_roach:
Yeah, not sure where they're getting those numbers from. Was getting out of the box about 3400 on Quadrant and about 85Mflops on the multi-threaded Linpack... wondering if their testing methodology is off somehow.

Also note that apparently the TMO SGS2 also pretty well smokes the Skyrocket on Sunspider, which makes me think somebody is just incompetent at benchmarking.
[T-Mobile Samsung Galaxy S II SGH-T989] Darmokk:
We aren't bashing it, just trying to wring the best performance out of our phones. If the skyrocket was appreciably better for some reason I think we'd all like to know.

I only started this thread because stock vs. Stock the skyrocket 'seemed' to be a little smoother on GUI and rolling thru home screens, etc. Maybe it's just all the crappy bloatware and tmo crap on our phones as stated above?
[T-Mobile Samsung Galaxy S II SGH-T989] mikeb85:
Phonedogs review of the skyrocket showed that it gets 2200 on stock. I don't see the wow factor in comparing the two I'm glad I'm on tmo. And not att
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
Quadrant scores can not be trusted, it's too easy to foul :D
[T-Mobile Samsung Galaxy S II SGH-T989] mikeyinid:
The 2 phones are nearly identical. I don't think the person doing the review was competant enough to give both phones the 3x test rule(which i just made up). And, as AllGamer said, quadrant scores can be misleading
[T-Mobile Samsung Galaxy S II SGH-T989] Mitallust:
lol, an Engadget review. What do you expect?

Thank god for The Verge.
[T-Mobile Samsung Galaxy S II SGH-T989] Darmokk:
Lol, to be fair as I've said after using the skyrocket for a little while, it felt every so SLIGHTLY faster and smoother than my Hercules. The engadget review just made me want to start an XDA thread just to be certain there wasn't something I was missing.

I think it must just be the Tmo crapware that leads to the "micro-lag/choppiness" on the Hercules sometimes. I am still on the stock ROM but from what I understand that goes away once I am on a kickass custom Rom yes?
[T-Mobile Samsung Galaxy S II SGH-T989] Mitallust:
Very much so. Simply getting the stock Telus ROM will greatly improve your experience. Running Bullet 2.7b and Jugs 3.1 is just crazy. Undervolting and Underclocking the phone makes it last forever, overclocking it to 1.8 lets me get 4600+ scores on quadrant. Not that quadrant is a great benchmark for a dual core phone.
[T-Mobile Samsung Galaxy S II SGH-T989] dan.follett:
I think the increase in smoothness on the skyrocket is entirely due to the ROM. The processor is exactly the same in terms of what matters. Flash a skyrocket ROM and you'll see the same buttery goodness on your SGSII.
[T-Mobile Samsung Galaxy S II SGH-T989] mikeyinid:
i agree. after flashing a skyrocket rom on my hercules, it defintely ran a little more smoothly. we shall all know shortly, whitehawkx has the 2.3.6 ota working on the hercules :D
