I just have really one question on this hspa+ <> 4G etc. I read that t-mobile is working on bringing HSPA+ .84, which I guess is 84mbps (theoretical limit). So if a 3G speed actually is the same speed as the current 4G speeds does it really matter what they call it? I would prefer they advertise the speed, because for me it is the speed not the tech behind the scenes.
[G2 and Desire Z General] skinien:
I feel the same way.

They downgraded the definition of 4G just so carriers could advertise it. But recently, the ITU has come out and said that LTE-Advanced (100+Mbps) is "True 4G".

http://www.extremetech.com/mobile/114953-itu-designates-lte-advanced-as-true-4g

---------- Post added at 09:18 AM ---------- Previous post was at 09:15 AM ----------

You are correct. If T-Mobile does deploy a 84 Mbps market, and users can actually utilize that speed, that would be much faster than Verizon's speeds. However, the terms "3G" and "4G" are based on technology infrastructure, not actual speeds. It's confusing to the consumer.

---------- Post added at 09:25 AM ---------- Previous post was at 09:18 AM ----------

HSPA+ Advantages:

- Better power efficiency (battery life)

- Ubiquitous

- Can achieve speeds just as fast as current 4G

LTE Advantages:

- Better technology (easier to upgrade/maintain for carriers)

- Theoretically, can achieve speeds faster than HSPA+

- LTE bands being used by at&t and Verizon are in the 700 MHz range.

I bolded the item that I feel is most important. The battery life issue will be a draw when LTE is more mature and chipsets become more efficient. However, the only comparable HSPA+ network to LTE is T-Mobile and they operate in the 1700/2100 MHz bands. The lower the frequency, the farther the signal can travel and the better the building penetration. The fact that the signal can travel farther means that carriers can upgrade/enhance networks faster and cheaper (less tower maintenance).

If battery life and speeds are equal, I want the best signal.
[G2 and Desire Z General] dhkr234:
I think, OP, that your analysis is based on certain bad assumptions regarding the availability and use of LTE.

This "activation" thing really doesn't follow, except in this weird transitional phase, where the LTE carriers don't have a voice-over-LTE system in place. The problem is that LTE is only currently being used for data communications, with voice remaining over the older 3G networks (HSPA+, CDMA, whatever). It is because of the requirement of keeping both radios alight, that (1) battery consumption increases, and (2) it becomes necessary to DEACTIVATE LTE in order to preserve battery life.

Advantages of LTE:

-LTE is much more efficient in the handling of spectrum. You can cram a lot more bits into a time slot than you can with HSPA+.

-LTE eliminates the dual-protocol nonsense required for carrying a voice channel simultaneously with a data channel. A properly implemented LTE network will rely on VoIP services to deliver voice communications, maintaining ONLY a data network connection.

-LTE eliminates (at least it can...) the link between voice services and network provider. A proper LTE implementation will allow you to select your voice carrier separately from your data network, so you could rely 100% on, for example, google voice or voip.ms, the network provider is turned into a simple data channel.

Regarding the signal drop you mentioned in LTE, this isn't a problem with LTE, but rather a problem in the DEPLOYMENT. It does take time and money to put up the equipment and get a properly balanced network. There can also be issues regarding the utilization and availability of spectrum -- are those signal drops by chance associated with running LTE over AWS? Or are they running it on much more robust 700 MHz?

HSPA is a dated technology rigged up with life support. In CURRENT implementations of LTE, there may be some glitches, but these aren't inherent in the protocol, but in the incomplete or incompetent deployment. Continuing to advance an HSPA network is definitely cheaper in the short term than deploying a new LTE network, but eventually, the limits of that technology will be reached and you will be faced with a dated network and no convenient way to upgrade it to the new technology. IMO, its better to begin slow deployment now than to wait until its too late and be faced with the need to upgrade everything simultaneously.
[G2 and Desire Z General] captainreynolds:
Hey, thanks for raising some really good points here! You make a lot of sense, and in fact I think you and several others have kinda convinced me that in the maybe distant/maybe not-so-distant future, LTE will be the way to go.

Could you elaborate more on the bolded text in the quote above? How does LTE fit more data in a single time slot? Simply because it is faster, or does it tend to less latency between tower processing and phone processing?
[G2 and Desire Z General] tvdang7:
I wish t mobile was going lte for future reasons. We will be the only non lte carrier in the next year or so
[G2 and Desire Z General] mputtr:
that is... if tmo will survive in the next few years considering that they wanted to merge with AT&T. I read something about their sales not really doing well at all therefore they wanted to merge with AT&T and get out of the US market. If Tmo happens to stay for more than 4 years, I actually would want to switch over to them from AT&T. I'm getting sick of the price hikes and bull**** "streamlining" that they've been forcing on the customers.
[G2 and Desire Z General] craiglay:
Setspeed - I fully agree, I just wonder what will happen when GSM is switched off. In the Windows Mobile 6.5 days, I used to switch off HSPA altogether and use UTMS for extra battery life and 3G.

bradley_e_smith - I think anything above HSPA+ 21 Mbit is using MIMO (multiple antennas) and channels which I'm not sure we'll see in many phones. Its more suited to mobile broadband

They use different transmission techniques. As production technologies get better, more complex radios can be produced within the constraints of a mobile device.

Below is a VERY basic description of each technology. I'm not a radio engineer, but have studied radio transmission techniques. If I've got anything wrong, please shout. For more information, goto Wikipedia.

2G - GSM uses Frequency Division Multiple Access AND Time Division Multiple Access. The data is transmitted using Gaussian Minimum Shift Keying

Essentially it has to tune into a frequency and wait for its allocated time slot. From what I understand, GMSK encodes data by changing the frequency and phase of the signal.
​

3G - UTMS uses Code Division Multiple Access.

This is a spread spectrum technology. The data is encoded by combining a code and data together and transmits over a shared channel. The receiver combines the code with the input signal to extract the data. Without the code, only noise is heard. Devices transmit using different codes which is perceived as noise and discarded. For HSPA, Data is transmitted using higher order Quadrature Amplitude Modulation. As the order gets higher, the signal gets less robust and prone to interference.
​

4G - LTE uses Orthagonal Frequency Division Multiple Access.

Essentially, the data is encoded and simultaneously transmitted over many sub channels. Each channel has a slightly different frequency with data transmitted using Quadrature Amplitude Modulation (I believe). This means the rate of transmission for each sub channel can be slower which improves signal quality while maintaining a high data rate (many sub channels). This is a very efficient and flexible method of data transmission.

In my opinion HSPA+ is better than LTE for now. The battery life issues with current LTE devices are a deal breaker for me.
[HTC Amaze 4G] adslee:
Hey guys, I think I might've bricked my Amaze :(

I was flashing a new ROM with CWM, used the superwipe script that X posted and formatted /cache, /data, /system. After the superwipe script, it reboots back into recovery, but when it tried to, it just gave me the green htc logo.

So I went into the bootloader and tried to get back into recovery through there, but it still just gave me the green htc logo. I then tried to install CWM again through the fastboot flash recovery method which was "successful" according to this:

c:\Android>fastboot flash recovery recovery-cwm-ruby-5.5.0.4.img

sending 'recovery' (5740 KB)...

OKAY [ 1.238s]

writing 'recovery'...

OKAY [ 8.469s]

finished. total time: 9.708s

However, everytime I try to get into recovery, it's the same green htc logo!

I formatted /system and /data, I don't think I have a ROM to normally boot to.

I tried to use every other method to reinstall CWM, but it just isn't getting past that htc logo screen.

I've tried using fastboot erase recovery to see if I could clean that partition, but it gave me this:

c:\Android>fastboot erase recovery

erasing 'recovery'...

FAILED (remote: not allowed)

finished. total time: 0.003s

I've also tried relocking my bootloader and unlocking again, after re-unlocking, nothing changed :(

Lastly, I tried "fastboot boot recovery-cwm-ruby-5.5.0.4.img", which supposedly downloads the image file and boots right into it, but that also didn't work.

I'm pretty screwed if I can't get this device to work again since I'll be left with a $500+ brick and no phone to use, so if anyone can shed some light as to what I can try to get this thing working again, please do!

Edit: not sure if this will help, but this is my "fastboot getvar all":

c:\Android>fastboot getvar all

[HTC Amaze 4G] Binary100100:
Hate to suggest it but the same thing happened to me as well.

I didn't feel like messing around so I just used a PH85IMG.zip file and started over from scratch. I think it might be an issue with the wipe script but can't be sure.
[HTC Amaze 4G] adslee:
I'm downloading the Globalive RUU (since I'm with WIND) right now and it's going really slow... Hoping this will resurrect my Amaze
[HTC Amaze 4G] Binary100100:
As long as you have access to fastboot you're phone isn't dead 99% of the time.
[HTC Amaze 4G] adslee:
And you're absolutely right!

I relocked my bootloader, finished downloading that stock firmware, and it booted back up to stock, phew!

Thanks a bunch for the suggestion there Binary, I was hoping for a more elegant solution than to revert back to stock, but I'm just thankful that I'm not sitting at home right now with a $500 brick :D

In case this happens to anyone else, I guess the surefire way to get things back up and running again is to relock the bootloader and go back to stock :)
[HTC Amaze 4G] Binary100100:
Glad to help.

ALWAYS make backups. Preferably on your external storage space becomes sometimes those RUU files wipe your internal storage.
[HTC Amaze 4G] lazypc:
Seems like if two people have had this problem it might be safer to just use recovery to wipe the phone, then flash the Rom. That way there is no reboot and less of a chance of a soft brick.
[Samsung Infuse 4G] namloki18:
the tittle.....plz help me:D
[Samsung Infuse 4G] Dani897:
needs to be in a supported codec. that's all. if its a hellraised rom then maybe it has the wrong video app and libs. the galaxy s only supports 720.. also try diceplayer, if the video can be hardware accelerated diceplayer works a little better than the stock one sometimes. they can't sell it right now but after the trial you can delete it and redownload it.
[Samsung Infuse 4G] threi_:
i don't think diceplayer is a trial anymore...they changed it to ad-supported, which is great IMO.
[Samsung Infuse 4G] aly_hosny:
Try MX video Player

and Download its codecs
[Samsung Infuse 4G] GGXtreme:
DicePlayer. I've yet to find an alternative. All other players rely on software decoding for video that the stock player doesn't support, which is unfeasible with 1080p/high-profile. And it will hardware decode videos even if the stock player can't play them (ie. 1080p high profile on a Captivate).
[Acer Iconia A500] cheddaface:
I'm new to this tablet, only had it a week and relized people cant hear me when i Skype with them. So before i purchase a head phone set with a mic on it i wanted to ask here to find out what is the best solution ??
[Acer Iconia A500] castafiore:
I use a stereo headphone (make Wesc - more or less 50 €) with a little microphone which is located on the cable (close to the headphone). The sound is crystal clear.

I didn't find any other solution for using voip (skype, google) with this tablet.
[Acer Iconia A500] tabasco22:
I use it in three ways.

1- like castafiore do.

2- using only a headphone, no mic. (use the internal mic)

3- using speakers conect to heatphone plug. (use the internal mic)

I think that the "plug" disconect something internal in reference with the "cancel noise system."

Please excuse my bad english.
[Acer Iconia A500] cheddaface:
So are you saying that all I need is head phones no mic?
[Acer Iconia A500] tabasco22:
Yes.

If you want better results, you can install: "volume control"

market.android.com/details?id=com.revsodev.volumecontrol&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5yZXZzb2Rldi52b2x1bWVjb250cm9sIl0.

and high the "in-call volume".

Try skype test.

I talk with my son every night and he hear me wery well.
[Acer Iconia A500] bullyspud:
Unlike tabasco22 even though the noise is reduced when there is something plugged into the headphone jack, the internal mic is not usable for skype.

it seems that there are many headphone/mic sets that work, though i have tried 2 iphone sets that do not .
[Acer Iconia A500] tabasco22:
I use SONY headphones ,speakers.
[Acer Iconia A500] ronkoni:
using a $1.50 headset with mic i got from ebay. works great. actually it works way better then it should for that price. :)
[Acer Iconia A500] cheddaface:
yo all have been thanked
[Acer Iconia A500] dincdoes.me:
I was gonna just drill a bigger hole in mine lol I guess I could be more logical ill try volume control + see if it helps any :rolleyes:
[Acer Iconia A500] castafiore:
Making a hole?

There is another solution: take off the back cover of the tablet. If you do a test with the two microphones totally uncovered (as I've done myself), you will notice that there is NO improvement at all.

Evidently, the problem doesn't come from there...
[Acer Iconia A500] dincdoes.me:
Yea figured thanks for the info:thumbup:
[Acer Iconia A500] deepdelete:
Anybody tried remove second mic? I mean sound canceling mic. Or maybe just cover it with tape.
[Acer Iconia A500] tabasco22:
I think it's a software problem, between the level of the microphone and cancel noise system level

This problem disappears when you insert any kind of plug into the speaker output., which cancels the "noise canceling system".

deepdelete, you phisicaly disconect the "sound cancelling mic" when you insert a plug.
[Acer Iconia A500] deepdelete:
I think sensitivity of sound canceling mic must be lower, or it must be placed somewhere else.

Sure there is also possibility to correct things with software mod.

http://en.wikipedia.org/wiki/Noise-canceling_microphone
[Acer Iconia A500] castafiore:
Yes, I did try that as well. But it doesn't make any difference neither.

I think you could be right, deepdelete. The second microphone on the a500 faces the back of the tablet (opposit the user).

But the 2 microphones are so closed to each other that the desired effect (as explained on the link you give), the "noise-cancelling", doesn't work properly. It's just a guess but it sounds logical (to me, anyway :) ).
[Acer Iconia A500] Moscow Desire:
Surprised nobody mentioned, removing the tab from the cover if you use one.

Found this out the hard way. Tab's cover, actually covered the mic! And, if I held it in my hands, it actually picked up the residual sound my fingers made when holding it. Resulted in a "garbled" sound on the other end.

I found with skype, the best thing, was to remove it from the cover, and place it on the covers "stand".
[Acer Iconia A500] masbret:
Where is the microphone located? I can't even use the voice search function with mine.
[Acer Iconia A500] erica_renee:
STUPID MIC locations... AGAIN AGAIN AGAIN AGAIN AGAIN AGAIN

There are two mics..

ONE is dead center in the grove between the glass and case at the top of screen. you will see a tiny slot..

the second one.. on the right of the sd card door you will see a tiny hole.. Its right under there.. This one is for background noise canceling. Like from the a500s own speaker.. and does not work well.. The mic works ok with yahoo messenger.. if YOU HAVE NO BACKGROUND NOISE AROUND or you cover that back mic..on not well BUT BETTER THEN IT DOES WITH GTALK OR skype ..

it just sucks is all there is to it.. I tried replacing the mic with a high end known to work well mic . NO LUCK So its either a hardware chip.. or software issue.. Do not think this will ever be fixed .. USE HEADPHONES

[Atrix 4G Q&A, Help & Troubleshooting] 95rr900:
IMO, you can't go wrong with Nottach's Wet dream rom. He has 4 or 5 themes for it, and the rom itself has a lot of tweaks so you can personalize it to your liking Best rom around for a fully functional atrix!

I personally run his 1.3 version with the ics redux theme (I did tweak the theme a little in spots that had unreadable text)....but this rom is an excellent daily driver!

If you know how, it's pretty easy to make a decent theme in the UOT kitchen!
[Atrix 4G Q&A, Help & Troubleshooting] Skenzin:
I second wetdream. I've been running it for a day now and it is a very very clean rom. I think it may be daily runner until more final cm9 comes along.

Alien v4 is also a good rom. It is old but it is a great take on official at&t GB, it is very stable. At my lowest times during a bad case of flashitis I curse myself for ever leaving it.

honestly, As far a blur roms go I havent ran too many I liked.

In my opinion whatever rom you run stick to stock at&t kernel. Personally I find too much flakiness when I run a third party kernel. Others have no problems though so take it for what it's worth.

I used Aura before darkside but the dev ran out of time to make updates to that rom.
