[Thunderbolt Q&A, Help & Troubleshooting] allquixotic:
Using a Verizon / HTC Thunderbolt, final retail model.

Not even tethering, just holding the phone in my hand, I'm getting 4 bars of signal and a signal strength of -77 dBm.

Seems to work fine most of the time, with good downstream, well within acceptable limits of the "5 to 12 Mbps" advertised, though it's extremely variable (it tends to regularly oscillate between these speeds, occasionally dropping down to EvDO speeds).

But the speeds aren't important, just an indication of the good signal strength.

Maybe it's just my cell tower, but I am very frequently seeing no network activity at all; can't even get to google or check for software updates. It's about as unreliable as Verizon's crap DSL. This is the polar opposite of the rock-solid stability I used to get with EvDO in the exact same place (in my house). Is it the 4G network being unreliable, or the Thunderbolt? Anyone else have this problem?

Edit: In terms of the patterns of the total downtime, it seems to go down for periods of 5 to 10 minutes per hour. Sometimes the downtime only lasts 15 or 30 seconds, other times I am completely out for 10 minutes, even though it says "4G LTE" in the dock and I am still getting good signal strength. My data usage for the month is under 5GB but above 2GB. I tend not to make very bursty traffic; except for app downloads, most of my traffic is of the low throughput, consistent variety (loading webpages, listening to MP3 streams at 128Kbps, etc). I use it very often but the bandwidth usage at any given time is probably lower than the speed of an EvDO connection (unless you count webpages that are downloaded at faster-than-EvDO speeds for a split-second to load them). I'll be using it and then it's just *down*. I can still make phone calls during the outage.
[Thunderbolt Q&A, Help & Troubleshooting] brandnewsimmy:
I noticed the same thing. I was all over the place cycling through no data, 1x, 3G, and 4G in like a minute in the same spot. I rebooted and got a much more stable 4G connection.
[Thunderbolt Q&A, Help & Troubleshooting] fillyo:
I'm thinking your expectations are a little too much. There are many areas I don't get a good 3g, let alone a 4g signal. I live in a suburb of Chicago and am in 4g 95% of the time, I don't always pay attention, because, after all, it's a phone first, but 4g seems to be there whenever I need it.

Also, in regards to unacceptable, what are you comparing it to? Is there more acceptable 4g signals in your area?
[Thunderbolt Q&A, Help & Troubleshooting] allquixotic:
I'm comparing it to Verizon EvDO / 3G. While speeds on EvDO were only about 20-25% of the max speed of LTE / 4G, it was completely reliable -- at least in my area.

Keeping the phone almost completely stationary sitting at my desk, connected to the same cell tower, and with my roaming data programmed to the latest version, my EvDO phone (a Droid 2) would have the connection available whenever I asked for it.

With the same exact usage pattern but with LTE, my Thunderbolt often has no connection, and it spontaneously comes back by simply waiting around for it to become available.

I expect the 4G channel to be "open" 24/7/365, not ever completely down -- especially while stationary in a standard building with a very high signal strength (always 4 bars). I have no unusual EMF like microwaves or bluetooth going on, just a laptop and a desktop and 2 LCDs. Wooden house, and I'm on the top floor.

If they can make EvDO stable 24/7, and EvDO is based on the same CDMA technology as LTE, why can't they make LTE stable 24/7 also? And I also don't understand why my phone does not fall back to EvDO if and when the LTE drops out. I recall a few times over the years of using it that my EvDO would fall back to 1x/RTT in the event of an EvDO downtime. But the MTBF of EvDO downtimes in my area was around 1 year. Now, the MTBF of LTE is about 50 to 120 minutes.
[Thunderbolt Q&A, Help & Troubleshooting] allquixotic:
I rebooted my phone and am getting a more stable 4G connection now, too :) I wonder if the phone itself has a stability problem with its 4G transceiver after a certain period of uptime? I will test this theory over the next couple days by rebooting my phone whenever I have a problem, and see if it helps.

Edit: I usually keep my phone "up" 24/7, and just leave it on the charger when I'm not on the go. I power it off only rarely, because I want to receive phone calls and text messages. When I just rebooted it, it had 2.5 days of uptime (hard to have too much uptime considering launch day was just a few days ago!)
[Thunderbolt Q&A, Help & Troubleshooting] Thrillhouse847:
Out of curiosity, what suburb are you in that you're getting 4G 95% of the time? I live in Highland Park (about 20 miles up the north shore) and I don't have nearly as good of coverage (still decent though and I'm not complaining).
[Thunderbolt Q&A, Help & Troubleshooting] rajuabju:
I'm guessing it has to be your area. I am getting amazing 4G coverage in LA. I going to assume its going to take VZW some time before their 4G coverage truly blankets areas. I remember when 3G came out.. it was totally spotty for a long time until they had enough towers.
[Thunderbolt Q&A, Help & Troubleshooting] distortedloop:
Kind of like what I recorded on my phone this afternoon....?

http://www.youtube.com/watch?v=qRTOCFoGFmU

5 min clip showing me cycling through web and map but getting no data, despite cycling airplane mode on and off. This has happened almost daily since getting the phone last Thursday, in multiple locations that are supposedly full 4G areas. Pretty annoying.

Double annoying since I got the Verizon phone because they're network's so much better (allegedly)...and yet my Nexus S on T-Mobile had full bars and fast "4G" data in the same location. I'd also had a reboot, and the 1tx symbols flashing but wasn't recording at the time. I'd been screwing around with this for at least 10 minutes before activating ShootMe to record it.
[Thunderbolt Q&A, Help & Troubleshooting] RafficaX:
Well im in Gurnee area with 4g 99% of the time. Only time without is in my GF's brothers house. no 3g there either though lol. otherwise i never loose 4g. Even driving to vernon hills and around i always have 4g. not sure y in HP u dont always have it.
[Thunderbolt Q&A, Help & Troubleshooting] lorijuan1024:
i am complete opposite i have 2-1 bars inside a building getting 12mbps
[Thunderbolt Q&A, Help & Troubleshooting] two_cents:
I notice it has an issue where it just randomly drops all my signals to search for 4g even though its not in my area... I think the only way to get reliable signal would be to set the radio to whatever you are using mostly... *#*#4636#*#* will get you into diagnostics and select phone infotmation and then choose CDMA auto for 3g or lte mode..... I'm thinking in the near future there will be a update that allows for easier lte turn off like 4g on the evo... the automatic thing is nice but it wastes battery and seems to cause some problem
[Thunderbolt Q&A, Help & Troubleshooting] Thrillhouse847:
Hm. Not sure either, Gurnee/Vernon Hills is pretty close, maybe I just need more testing time (I'm also indoors most of the time).
[Thunderbolt Q&A, Help & Troubleshooting] RafficaX:
i mean i never saw 4 bars on 4g but 2-3 always and hit 30 on the down and 50 on the up while in the antioch walmart lol but never with out 4g expect in that one house lol.
[Thunderbolt Q&A, Help & Troubleshooting] itzjonjon69:
I just set mine to LTE only let's see if its more stable than the auto mode
[Thunderbolt Q&A, Help & Troubleshooting] RafficaX:
let me know, i should try that too. never thought of that when looking at it. wonder if ill save a bit of battery not trying to also find 3g, im sure i lose very lil hunting for 3g but still. saving some battery may give me another in on 4g lol
[Thunderbolt Q&A, Help & Troubleshooting] distortedloop:
You realize that the phone is incapable of 50 up, don't you? Those kinds of speeds are a known bug in the Speedtest.net and other similar speed tests that don't deal with the Thunderbolt's large transmit buffer properly.
[Thunderbolt Q&A, Help & Troubleshooting] intangibleDroid:
Anyone else seeing any errors in the logcat that look similar to this?

D/DATA ( 1779):[QCTMM] DataNetStatistics sent == 0 && received == 0 newActivity=NONE

D/DATA ( 1779): sentSinceLastRecv=0,watchdogTrigger=10,maxindex=0

There is an entry like this every few seconds when I'm on mobile data.
[Thunderbolt Q&A, Help & Troubleshooting] ajftl:
verizon towers fallowing u now? from 95% now 99% lol ...that 1% its your gfs house damn it.... probably a bridge on the way and tower to tall to go under ...****...otherwise u would it have 100% wooohoooo
[Thunderbolt Q&A, Help & Troubleshooting] rotorocker:
I'm at my desk at work in times square, nyc. Yesterday I had 1-2 bars of 4g at my desk. Today, my phone has yet to switch out of 1x mode my entire 2 hour commute here and so far today. I tried rebooting and can't get 3g or 4g to come on. I'm pretty annoyed

Port G2 Rom IceandFire to HD2? That's all I'm asking, he has such great status bar icons that I love if someone could do it, it would be much appreciated! Thanks
[Atrix 4G General] rex-tc:
I am sick of everyone thinking the upcoming dual-core devices will blow away tegra 2.

Tegra 2 vs Dual Core A5 (Ipad 2)

A lot of talk about Andntech OpenGL benchmark trumping Tegra 2, but what about Stockfish and Benchit Pi where A5 got slaughtered (PC Magazine)? With half the RAM and lower clock I don't see this thing smoking Tegra 2 in all benchmarks, or real life CPU situations.

Tegra 2 vs Exynos (Some Galaxy S2)

Lower benchmarks in Smartbench Gaming. Plus there is early benchmarks of Quadrant scores of 2100 tablets running the Exynos 4210. There is a reason why Samsung Galaxy S2 is including Tegra 2 in some regions.

Androidevolution.."One negative surprise on the S2 so far has been the level of GPU performance. So far, most of the early benchmark shows that Exynos 4210 isn’t up to par when it comes to the GPU performance. This is strange given that Samsung was leading the market when they introduced the previous generation SoC ...... Smartbench 2011 GPU numbers are once again, very disappointing"

Tegra 2 vs Dual Core-Snapdragon (HTC Pyramid)

This thing got smoked in Smartbench with gaming and productivity.

" Their tests confirm that the Pyramid indeed houses a dual-core chip, but the popular Smarbench 2011 shows a CPU and GPU that simply don’t hold up to the Tegra 2 chip found in the LG Optimus 2X and Motorola Atrix 4G"
[Atrix 4G General] dinan:
Yea you're comparing pre-release builds of phones (S2 and Pyramid) with a Tegra 2 which has been out for months? Also, it's sad how poor the Tegra 2 platforms perform compared to the SGX540 which has been out for half a year already and still gets outscored in most benchmarks.

Oh and if you look at the most recent GLBenchmark 2.0 Egypt... Samsung's Exynos scores around 4000 compared to the Xoom's 1300 and Atrix's 2000. Even the original Galaxy S scores higher... around 2400.

Odroid-A Tablet which runs Exynos: http://www.glbenchmark.com/result.j...version=all&certified_only=2&brand=Hardkernel

Xoom and Atrix: http://www.glbenchmark.com/result.j...4&version=all&certified_only=2&brand=Motorola

Original Galaxy S: http://www.glbenchmark.com/result.j...=0&version=all&certified_only=2&brand=Samsung

And don't even bring up the Ipad 2. That thing has a dual core SGX543 which even in the single core version outperforms the SGX540, which the Tegra 2 can't even beat.
[Atrix 4G General] ChongoDroid:
****ty deal... I wonder how much software it will take to make it speedy gonzales
[Atrix 4G General] lorijuan1024:
ouch well put??? lol
[Atrix 4G General] Nado85:
Are you freaking kidding me?! You're an idiot mate.

All these devices have different resolutions so obviously your devices with **** resolutions (ie ipad) will have awesome scores.

Dude seriously poor effort.
[Atrix 4G General] tadjiik:
Both the Ipad2 and the Odroid run at higher resolutions than the Atrix, that should make them worse, not better off.

The Xoom is ~30% larger than the ipad2, but that is not enough to explain why the ipad2 is 4 times better

The Odroid is again larger than the Xoom, and that performes 3 times better than the Xoom.
[Atrix 4G General] Mafisometal:
you know what this points out? That people are VERY stupid and care too much about upcoming technology! Everything people buy ends up being obsolete in about a week or two. Its REALLY sad to see this because these software developers put a lot of time for something that will only be hot for a few weeks and then its yesterdays news. That's why software is getting choppier, and there is no quality backing anymore.

Aside from my *****ing...i do like how that Samsung platform works..quite impressive, i'd like to see what Nvidia will do next. These new technologies have been pushed mad crazy this last year. I think quality and reliability will take a hit quite hard due to the silicon being pushed to the limit of its threshold...we're not too far from that.
[Atrix 4G General] cheetah2k:
Silicone has a long way to go before it max'es out. The good news is Nvidia has years of quality GPU fabbing and they've got loads of tricks up their sleeves yet.

What Samsung and Qualcomm dont have right now is games & software optimised for their chipsets. This is where the Tegra II is a step a head of the rest..

So don't stress peoples!
[Atrix 4G General] cheetah2k:
Also, the Atrix is also running Android 2.2, where as the Odroid is on 2.3 which is optimised for dual core CPU's.....

We will all see a big difference when Moto release 2.3 / 2.4 for the Atrix.
[Atrix 4G General] twistedneck:
I can confirm the SGX540 (iphone 4 graphics processor) beast tegra 2. i know the resolution is lower, however the smoothness and especially quick scrolling on jam packed websites like non moble youtube for example show its smoother.

i have not done a bench yet. i am more than happy with my atrix. actaully i just got an amd zacate fusion e350 and its on part with my atrix dual core yet eats 18watts. actaully, the atrix plays less choppy than the zacate.

however, its not as fast 'yet' as the sxg540 and OMG i bet the SGX543 is awesome.
[Atrix 4G General] Techcruncher:
The iPhone 5 had a higher resolution then the atrix, yet scored 15-16 fps in tests where the atrix gets 48-50. The tegra 2 I'd very future proof for s few.months especially considering that man manufacturers are still making single core phones.

To see what optimization can do. Download fruit slice, and compare it to fruit ninja tegra HD.
[Atrix 4G General] tadjiik:
Are you refering to the iphone4 here? That has a SGX535, which is worse than Tegra2, that is correct. But it is still not beating SGX540 (Samsung galaxy s), they seem to be about on par, according to glbenchmark.com. If you were refering to the ipad2, that beats tegra2 in just about anything.

And what proof do you have that those games are not able to play on non-tegra phones or (more likely) could be optimized just as well or better for non-tegra phones? Throwing up a game that has not really been tested on non-tegra phones does not prove anything.

To throw the ball back, if you want to see what optimizations can do for Exynos do a search for "engadget exynos gdc", which has a 1080p 3D demo @60 fps (I am unable to post links...)
[Atrix 4G General] dinan:
lol nice try.

oh and "your devices"? I like how you assume I'm an apple fanboy when I'm actually a die-hard android user... i HAVE an atrix, a nexus S, a nexus one. What phones do you have? and the benchmark scores I posted were all between android devices so I'm not sure where you're seeing these "awesome scores" for the ipad?

come back when you actually have something to contribute.
[Atrix 4G General] SlimJ87D:
You really need to wait for benchmarks on the EVO 3D to come out.

And you really need to see a finalized and optimized (Driver wise) S2.

To make a fair comparison.
[Atrix 4G General] rex-tc:
Again more OpenGL benchmarks that prove nothing, nothing more than a fillrate test at best. The Tegra 2 has already proven to be better at productivity and a has twice the RAM as the ipad 2. Which means higher res textures and with the better CPU better physics with PhysX. SGX is nothing but a tile renderer that fakes what a true T&L engine produces. When you start having more CPU centric games with high res textures we will see who will prevail. Plus the toolset of NVIDIA is MULTIPLE times better and we are already seeing straight PC ports.
[Atrix 4G General] vista1984:
in the paper,,tegra 2 should be the weakest among them..

in fact, on the test, tegra 2 is not fall behind.

i still think exynos, a5, c2 snapdragon's performance will be better than tegra2, just the matter of time.

well, tegra2 is good enough. but tegra3 and tegra4 are the ones that take the lead.
[Atrix 4G General] dinan:
Well until those "CPU centric" games you're talking about actually come out, the only thing we can compare it to is what's out there right now. If you want to see the Tegra 2 get shamed by the iPad 2's SGX543... http://www.anandtech.com/show/4216/...rmance-explored-powervr-sgx543mp2-benchmarked
[Atrix 4G General] tadjiik:
The tests are comprehensive and test different parts of the chip/driver. There is a few "real-life" tests, as well as a bunch of synthetic tests.

Wait, so the "productivity" tests do prove something :) Well, I belive the ipad is clocked somewhat lower than T2, so no real surprise there. Trying to differentiate between different Dual-A9 cores might be hard, though, since they are all based on the same design. The only thing I could see Tegra2 had donewas the inclusion of a hardware JPEG decoder on the Tegra2, that might skew the productivity tests a little. On the other hand, they are not including NEON, so for tests that include that, they might be at a loss.

Do you even know what a tile renderer is? It is not "faking" what a true "T&L engine" produces, it is about not doing rasterization and fragment processing until frames are swapped, thus enabling the use of only a small render buffer (a tile). The only thing it "fakes" is that overdrawn pixels are not fragment processed - but this is also done on non-tilebased to a lesser degree (with early-Z).

By the way, "T&L engine"? There is no hardware "T&L engine" anymore - all is done through shaders nowadays.

If we are talking CPU centric, then Tegra2 will be at a loss because of its lack of NEON (which I belive Exynos supports). I am not sure if the Apple has it, but that is still comparing apples and oranges (different OS) when it comes to benchmarks.

Could you point me to the toolset? When I googled "tegra2 toolset", this post was the first...

Are we seeing PC ports? Could you mention some names/examples? Any reason why they will not run on non-tegra2?
[Atrix 4G General] haloimplant:
No no no it's important to cherry-pick and declare victory as soon as possible. ;)
[Atrix 4G General] Brumble:
I think people need to wait for release of the actual phones before comparing, I mean htc havnt even announced the pyramid an people think its crap because of its in development benchmark, of course scores are going to be crap if its still in development?

Sent from my thumbs
[Atrix 4G General] hotadef:
Yeah im waiting it out im getting the g2 or pyramid if i stay with tmobile or something similar on sprint as i dont like at&t and verizon is to expensive even with my 25% discount
[Atrix 4G General] MarcMaiden:
Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software Software

Benchmarks are useless...sure they give us an idea of what our graphics "can" do, but you have to remember developers still have to make the software to take advantage of that. The samsung galaxy series is a year old, but im pretty sure there arent many things that take advantage of the graphics processor in them. That being said, I have a lot of faith in Tegra 2 because nvidia has a tastey set up for developers IE the tegra zone which helps market tegra games better which = more sales for developers = better products
[Atrix 4G General] nickgto:
Tegra 2 is the first dual core A9 soc in the market so eventually the newer A9 based socs should eclipse it's performance. It's just a matter of time. Ti's OMAP 4430 with Neon support and higher clocked SGX540 should provide better performance.
[Atrix 4G General] hotadef:
hardare is part of the equation and so is resolution for some bench marks. as the optimus beats the atrix in many benchmarks and has less memory. and the other part is plan ole software. As you can see apple i hate but they sure can have a silky smooth experience with lower specs due to it the software being optimized for the hardware. that being said the phones with superior hardware if optimized completely the skys the limit
[Atrix 4G General] Clienterror:
You hit the nail on the head. I'm sorry but I doubt any android device will be as smooth as an idevice. Reason being is they are developing their software to only run on a hand full of devices (maybe 4?) so they can optimize it almost perfect. Where as any android release will be running on possible 50+ different handsets with varying levels of ram/CPU speed/screen resolution/GPU chips AND also the carriers are messing with the original code as well which throws optimization out the window even farther. This is just the price you will pay for living in a non walled garden. The only way I can see an android device being as smooth as a idevice is if the hardware can make up for the unoptimized software IE have crazy specs.

Just my .02
[Atrix 4G General] paravorheim:
You say non-walled garden, but that Atrix is far from the open garden I had dreamed of when making the jump from iOS to Android. I'm not giving up hope on that unlocked bootloader, however, so I'm stuck with it, for better or for worse.
[Atrix 4G General] Clienterror:
I understand, it does have a locked boot loader (and I'm also hoping theres a method around this) but even a locked boot loader android device is WAY WAY more customizable. I think it took like what 3 years for iphone users to get an option to change their background (Non jail broken, it's pretty sad you need to hack your phone just to change the background or icons or ANYTHING)? You can still do quite a few things with a locked boot loader, just no OCing or playing with the kernel. You can theme, change your launcher, deodex your files ect. and you can do all this without even rooting. You'll also notice that when people jail break their iphones they tend to go slower, once again because they are deviating from the one flavor fits all iphone template.
[Atrix 4G General] paravorheim:
I completely agree with you, and it is way more customizable. However, if you're on this forum, and you own(ed) an iOS device, it's probably jailbroken, and either customized and/or removed of bloatware (unneeded languages, launchDaemons, etc.) to your heart's content. But the Atrix is a beautiful phone, and nobody is going to take it from me.
