great question. the difference between att talk and surf with sprint talk and no surf is due to the difference in radio technology.
sprint & verizon use cdma, att and tmo use gsm. gsm allows data and voice to travel over their radio at the same time while cdma does not.
the work arounds for this are to use one of the other radios in the device, either wifi or 4G (wimax on sprint) will allow the user to talk and surf at the same time.
not sure there is anything a developer can due to remedy this issue since the root cause is due to hardware/technology limitations.
hope that helps!
Right now you can do it if you're on WiFi...but you will not see it without being on WiFi any time soon bud...Problem is the radio...

Edit: seems I was 1 minute too late...
well at least we can do this with 4g and WiFi ill try it out right now thanks for help guys.
Yup only way to do it is on 4G or WiFi. I don't think devs cab do anything about it.

I was Also wondering about this issue, I would say that's about the Only thing the IPhone has over us!
That would be awesome if a Dev can do this mod for us I get sad when i see that iPhone commercial with those guys using the internet and tlking on the phone at the same time. Iphone Bastards LOL

Its not just iPhone. Its T-Mobile and att. Their android phones do it also. Its a GSM thing. Sprint is cdma rev a. And use the same frequency for data and voice so its not possible yet but with the introduction of rev b it opens up the possibilities of it becoming true. No mod can be done unfortunately to fix this. The only way it would work right now is if u were using either wifi or wimax then u could talk and surf. So if that diner had free wifi then u to could sit down with ur evo 3d andbdo exactly the same thing as that iPhone ur envying.
free the dirk
Depending on what Sprint has to say October 7th it may not be an issue for us anymore. Hopefully that will be the case.

I was able to do this on the MyTouch 4G on T-Mobile, they use GSM just like ATT.

That's sorta correct.. But not completely...
Actually GSM doesn't support simultaneous voice and data, UMTS does. And the way UMTS supports SVDO is because BOTH voice and data travel in the same channel and is separated by code.
CDMA and EVDO are actually two different networks altogether technically. Voice travels over 1xRTT while data can travel over 1X or EVDO.
Seeing as there are two different networks, the phone's chipset must be able to talk to both networks at the same time.
Verizon has 1 handset that supports Simultaneous Voice and Data on 3G EVDO Rev. B, the HTC Thunderbolt because of the chipset in the phone and it works great.
Sprint doesn't have any SVDO capable phone's so therefore you can't talk and surf unless on WiMax or WiFi. Its all handset based, not network dependent.
during some testing i have been doing on the 3d - i have had an active data connection and voice connection at the same time.
our chipset: Qualcomm Snapdragon MSM8660 RISC Multi-core microprocessor with embedded DSP
2x Qualcomm Scorpion Harvard Superscalar processor core, 266MHz LPDDR2 memory interface, Embedded DSP (GSM, GPRS, EDGE, UMTS/WCDMA, HSDPA 7.2Mbps, HSUPA 5.76Mbps, HSPA+ 28Mbps/11Mbps, MBMS, CDMA2000 1xRTT, CDMA2000 1xEV-DO, CDMA2000 1xEV-DO Rev. 1, CDMA2000 1xEV-DO Rev. B baseband), Embedded Seventh-generation gpsOne GPS module, gpsOneXTRA Assistance, Adreno 220 GPU
the catch: it was on HSPA+.
What was happening: look up our cpu/radio on qualcomm's site, and you will see it is a cdma, evdo a, evdo b, umts, gsm, hspa, and hspa+ radio. - if u see TrevE's notes on his download mode thread, you can see he connected directly to the radio, and it is a GOBI2000 radio, a global universal radio.
REF: page 11 --> http://www.scribd.com/doc/57334033/1XAdvanced-Web-02092011-NA-EXT
REF: page 18 --> http://www.qualcomm.com/documents/files/what-is-next-for-cdma-presentation.pdf
problem: these is no firmware or software on a stock 3d cdma phone for gsm. nor is there a sim slot.
using some firmware from the gsm phone, and some parts of the gsm rom and kernel - i was able to activate the gsm radio (gsm includes umts, hspa, hspa+)
since i had no sim card, the only phone call i was able to make was to 611 (and good old AT&T answered). the only web page i was able to see (no matter what address i entered) was a while page w/ an AT&T logo that said 'unauthorized device'
TrevE has some info on the partition structure of this phone in his download mode thread. there are some [EMPTY] partitions on the cdma phone that are used on the GSM phone.
i think once TrevE gets download mode done, we can use a 'esim' (or softsim) of some sort to use AT&Ts 14.4mbps hspa+ network
i did pull the 'unauthorized device page' will on the phone w/ 611.
the PCB used in the EU/ASIA phone is the same as the US phone (per HTC's service manual dated 6/2011). the EU/ASIA is short the wimax chip. under the wimax chip, are solder points for a sim card.
since they dont use wimax, but use a sim - and we use wimax w/ no sim - this makes sense. its also cheaper for HTC to have 1 PCB for multiple phones.

Yeah, sprint will be changing over to cdma rev b. this is a rumor, but I consider it a fact. It's an EASY update to their existing network. Our phone is completely compatible.

it would be a very easy - just a firmware update - no hardware needed
might need more bandwidth backhaul at the tower though...

I actually have an asus rt-n58u router (which is SUPER fast and strong), yet I could only get like 5 mbs on my prime! Great signal, but no speed for some reason.
I had the 2.4ghz N-only on channel 11 originally. When I moved it down to 1 or 3 in the 20/40mhz range, it upped the connection speed 5x from where it was so my transformer is connecting at 54-72 mbs instead of the 19 before.
Odd, but give it a try on your router and see what works!
That kind of makes sense - lower frequencies are better able to penetrate solid substances, so it might make the signal strength better.
It's very odd, however, that a drop of only 40 MHz would have such a huge influence if that was the reason. Are you in a highly-populated area? I think it's more likely that there was interference on the other channel. Do you have any other wireless devices to test with? Did you try putting it back to the original channel and seeing if the speeds went back down? Also, were you holding the tablet in the same position during both tests?
I live in a small condo complex, but I used wifi analyzer to see what channels the other networks were in... At my old 11 channel, there were zero, while at 3 there are 2 others to contend with. My laptop works at 300 mpbs at either channel but the prime seems to perform much much better at the lower frequencies.
Odd part is that the signal strength was the same between channels 3 and 11, the only thing that changes was the speed thoroughput. Suddenly the speed listed in Android went from 5mpbs to 65 ish by just changing the channel, yet the db- signal strength remained very good.
If anyone can explain this, I would be all ears.
I recently used Wifi Analyzer to change to channel 11 from 1. Why? Farther away from my router 11 was stronger than 1. So maybe speed is sacrificed by distance & vice versa? Wifi Analyzer also tells which channel is "better" but is it using "better" as determined by???
Interesting, I am playing around with the channels as well, and there seem to be differences in speed of each channel.
I live alone in the woods, where definitely no intereferences from other WiFi Networks appears.
Channel 11 works slightliy faster than channel 1, but I have not tested many configs yet.
The signal strength is not the issue because I am sitting right next to the router, but the speed behaves odd.
I cannot connect to my DLINK DIR 655 on channels 6 and 13, no problems on others.
The Prime WiFi wierdness continues

It determines better based on the channel of other networks in range. So the higher the channel rating, the fewer other networks there are in that frequency range.

looking at this from a physics standpoint, this makes sense. lower frequencies use more energy and so at a higher energy, you're able to pump out more speed. I'm guessing it's the prime that's using more energy since the router is not the device in question...
interesting though...you would think that it wouldn't make such a big difference!
FWIW, I've always gotten much better performance on my wireless network in both terms of speed and connectivity, using channel 1.
what app are you guy suing to test speeds? Speedtest.net

Yup. That seems to be the standard app for speed testing. If you really want to be accurate, the best thing you can do is transfer a large file locally over your WiFi network.

Interference. Other Overlapping wireless routers.
I'm a little skeptical of the OPs findings, as the difference in channels (in the tens of Mhz range) shouldn't make a significant (and definitely not a factor of five) difference in bandwidth. It is interesting though. Can you do some controlled test runs and provide the specific data?
I am just as confused as everyone else...but trust me it makes a big difference.
The DB rating at channel 11 was -40 (lower better), while the DB rating at channel 1 was -38. Again, channel 1 is crowded with other routers, yet 11 or even 14 is empty (no one knows how to properly use their router here!)
I would have full bars (according to android) at the higher wifi channels, yet the prime would only show 5 mbs, sometimes 19, but most of the time around 13-19mbs (per android menu, speedtest around 7 mbs). When I moved to channel 1, the prime (and my droid charge) would go to 52-65mbs (android, 13-15 using speedtest)...but my computer would go to 144mbs only because of no channel bonding.
Moving to 3, a 40mhz channel, my charge would get 52 mbs and my computer bonded to a full 300mbs. Channel 11 is a 40mhz channel too so not sure why 3 is any different than 11 that is also 40mhz, but the speed rates in android is consistently higher.
The test is through one wall, about 20 feet from the router. Could be just my router, but who knows! I have an Asus rt-n56u router, with dual bands. I would be curious to see what the tests would be at the 5ghz band if that was ever enabled in android.
My tests were in a controlled place, same spot for laptop, droid charge and my prime. All i did was change the wifi channels from 11 to 7 to 3 to 1 and see how it changed the speeds.
I measured the rates speed provided in android from the wifi interface and also used speedtest on all 3 to rate actual speeds. speedtest results went from 6-7mbs at channels 11, to around 15-16 at 1. Just checked again this morning and still faster.
Here is a wiki article picture on the bands:
http://en.wikipedia.org/wiki/File:NonOverlappingChannels2.4GHzWLAN-en.svg
I also got a significant speed boost from moving off channel 11 onto 1. Went from 3mbit to 14mbit
I am about to conduct my own channel 1 versus channel 11 tests right now...
I've just tried it on mine and Channel 1 and 11 were near identical and 3 halved my DL speed.
Did the most scientific test I could. Never moved tablet, same environment, same location, 10 feet from router, Los Angeles server, ran 5 tests as quick as possible on each channel - with 3 minutes in between to change channels and let the change settle - and then spent 3 minutes watching dbm strengths on each after all tests complete
CHANNEL 11 =2462mhz
0. ping ms/ down mbps / up mbps
1. 24 / 20.15 / 1.15
2. 22 / 20.44 / 1.16
3. 21 / 19.92 / 1.16
4. 18 / 21.81 / 1.17
5. 24 / 21.26 / 1.17
*high and low dbm over 3 minutes -36 to -47
CHANNEL 1 = 2412mhz
0. ping ms/ down mbps / up mbps
1. 21 / 19.84 / 1.16
2. 22 / 20.57 / 1.15
3. 23 / 21 / 1.13
4. 21 / 20.79 / 1.16
5. 23 / 20.34 / 1.15
*high and low dbm over 3 minutes -39 to -43
Results = Negligible differences with 1 real benefit to channel 11 shown by Wifi Analyzer is that it reachs around my home farther. Channel 11 seemed to stick to better dbm ratings but had wider range in high to low but stayed mostly in 30's. Channel 11 got the best average up speeds barely. Channel 11 got the best average down speeds barely. Channel 1 barley had best average png. As well, of the other neighbors signals I pick up, most are in 1 and 6 - no one on 11 but me. Thus, I will stay on channel 11 for all obvious reasons.

Looks like maybe you conducted your tests close enough to the router that the bottleneck is in your internet connection, rather than the wireless connection. Try again far enough away that the connection drops to like half of that speed on channel 11. If the speeds are still the same then, that will be strong evidence that it's local conditions causing the speed boost for those who report it.
This may be related to your routers and not the TF.

Easy enough.. will do maybe tomorrow at same time of day to try to best mimic and remove confounding variables best as possible (though saturday may have more congestion as people are home). Either way, will do in my living room, farthest point from my router. Will be interesting to see how distance changes results.
Hello.
I'm curious about the value of HSDPA as shown in my phone's status (I'm running Resurrection Remix JB v3.0.6).
No matter what I do, it always shows as HSDPA:8.
I set it on Build.Prop as:
ro.ril.hsdpa.category=14
which is what the GSII is supposed to support.
a. Network Info II claims my wifi link speed is 5 Mbps (just below the :8 limit of 7.2 Mbps).
b. My wi-fi speed, as per Speed Test, is close to 14 Mbps (my laptop gets around 17 Mbps) and that's what I'd expect.
So where does the :8 come from?
Is it the state at rest and changes as I download? Shouldn't it show the maximum supported category?
How can I see what its value is during download?
Thanks in advance.

u can check with play store for some third party apps that do speed test for u
I'm not sure I understood the question, but you can test your connection speed w/ this app https://play.google.com/store/apps/...DMsIm9yZy56d2Fub28uYW5kcm9pZC5zcGVlZHRlc3QiXQ..
Sorry for the mixup.
I know my connection speed as far as downloads are concerned.
I use 'Speed Test' as I mentioned and it clocks at around 14 Mbps.
My question is about the meaning of: HSDPA:8
As far as I can tell, it defines a network limit of 7.2 Mbps.
So how come I get 14 Mbps?
The only thing that crosses my mind is that maybe HSDPA refers to network speed limit, IF I download through the phone provider.
Maybe it doesn't apply to wifi connections?
I think it refers to the mobile network, I never heard of limiting the wifi connection through a setting xD sorry for my bad English!

Hi,
I have received my Beelink i68 from Banggood. On the site, the description says that it's a 100 mbps Lan, but on my router the orange led is on ( green and orange) that means gigabyte lan.
If I check the ethernet tvbox with app "Wifi speed test" which be able to test lan network, I can't get any speed measurement but app says : "link speed: ethernet mode 100 mbps (estimated)"
Then, the model number is i68G. I guess G means Gigabyte.
So, how to know if it's the 100 mbps or 1000 mbps device?
Is there an app to test speed lan network on android device.?
