[Android Software/Hacking General [Developers Only]] chiraag:
when the HELL will this be fixed...

i have 2 phones ACER stream and HTC Desire, both have the problem....

my desire was working fine.. but the acer was not, and i tried to play around with the my google account... Now i cant use MARKETPLACE on either one..!!!!
[Android Software/Hacking General [Developers Only]] strazzere:
Have you looked at the logcat? Anything of interest in there? Maybe try posting this...

I've owned two Android phones and been to several Verizon, att and sprint stores to test different phones.

It feels like only HTC Android phones are smooth. Other phones like Droid, Droid X, Droid 2 or Galaxy S, they all feel laggy and awkward. Even though HTC's hardware is probably the weakest. Motorola and Samsung have great screen and CPU in the phone, but they feel laggier than HTC's small Aria.

Is it just me?
[General Topics] tolis626:
No pal,you're not alone. :D

Both Motorola and Samsung must hire better software engineers for their UIs.Samsung's TouchWiz is crap and Motorola didn't even bother bringing a custom UI to their flagship device(the Droid X).It's not only the lag.Sense is also much more user friendly and nicer to work with.I was between the Galaxy S and the Desire and finally got the Desire because of it's software.I haven't even rooted it and am extremely happy with it.Now I'll wait for the next-gen of smartphones! ;)
[General Topics] Ricparr:
My captivate doesn't lag, not sure what you mean? As far as UI goes, you can replace them at any time so why let that be a deciding factor, unless you just love sense that is.

I will say however that I am stuck with att and had a hard time choosing between the captivate (samsung) and the aria (htc), but in the end I had to go with the bigger phone/processor. I guess the fact that I had any kind of hesitation picking between the two shows you just how good htc phones are, as the aria is not nearly as powerful as galaxy s, but it's still very VERY appealing!
[General Topics] mwxiao:
Well, I am using Captivate now and it is laggy. And I am sure I am not alone if you look at some of the forum posts.

If you try any of the HTC phones, you'll definitely feel it's much smoother than the powerful Galaxy S.
[General Topics] Ricparr:
Not arguing here, just curious what you mean by lag? I don't doubt your word at all, and I've read many lag complaints for sure but mine simply doesn't, or I'm not looking at it right.

This would also seem to fit right in with all the other issues on galaxy s devices that seem to vary by user. It makes me nervous about this phone and wonder if I shouldn't think about a different device...but I already have a backflip, this captivate, so that leaves me with the aria. Hmmmmmm...
[General Topics] Mithent:
The Aria is considerably below the Galaxy S hardware-wise.

I could have chosen a Desire from my carrier, but went for the Galaxy S and am not really regretting it (admittedly I might have been unhappier if I was a heavy user of GPS).

The lag is, as far as I know, the phone pausing (at a black screen, often) for a while, usually when loading programs. I've not found it to be a major problem myself, and there are now one-click lag-fixes available for Galaxy S devices as workarounds if you do find it to be one.

Hopefully both will be resolved by the time we get Froyo!
[General Topics] mwxiao:
It's the response time of your press. It's the transition between screens. Even though Galaxy S or Droid X is powerful, you will still have the delayed response every now and then. Or you will have some delayed transition animation.

It's not bad to use. It's just not as good as HTC's smooth experience. For me, iPhone still has the smoothest UI transitions and responses. HTC is the second. Sadly, Samsung and Motorola, with the best hardware, have the worst UI experience. Something is wrong with their software development.
[General Topics] mwxiao:
Yet Aria has never had lag issue. I've used Aria for a month and it was as smooth as you can expect from any big phone!

But I immediately feel laggy in galaxy s and Droid series. The screen becomes unresponsive when market is downloading and installing an app. Delayed response when pressing a button... Slow transition animation...

I think HTC is more committed to Android than other manufacturers. HTC has the most Android phones (right?) and they might have the most experience working with Google. Motorola and Samsung just started their series of Android. I think they rush themselves into this fast-growing market after seeing the success of HTC.
[General Topics] Ricparr:
ah, yes I see. Indeed it does seem unresponsive during a market install, and since I don't keep many apps installed, that may be why I haven't seen any home-screen sluggishness. I think what may be afoot here, is that since I have only owned 2 android devices, the first being the backflip (...), then I simply didn't even know that the sluggishness was there. Seriously. The speed/smoothness/experience on my captivate is so much better than my backflip that I was immune. lol. I really am considering going for the aria instead though, if samsung doesn't hurry up and fix the gps issue and other minor annoyances. Anyone think I have lost my mind to trade a captivate for the aria considering I don't really game on my device or demand the potential power it has?
[General Topics] htc fan89:
That's false x10 has a nice UI even though I admire HTC sense, its better than LG or Samsung's UI

[General Topics] snwagner:
Try autokiller from the market to help w/ lag, it's really great!!!!!!!
[General Topics] mwxiao:
It's just impossible to go back to Aria after Captivate's huge and beautiful screen...
[General Topics] fuinhu:
HTC will be the apple on the Android market...

Everyone will get a Galaxy Super S or a Droid XXX (because of the superior hardware), but at the end they will be all dreaming with a desire :D

Seriously, i think that has something to do with the developers, the G1 was the first android cellphone, and yes, it was a HTC
[General Topics] cyberchuck9000:
To me, the only way to enjoy Android is with a vanilla ROM (best performance) with Launcher Pro. Can't stand Sense, Blur, or Wiz.
[General Topics] gtg465x:
Part of the reason the Aria feels smoother than some of these higher end phones is because it doesn't have to render anywhere close to as many pixels. The Aria is pushing 154 thousand pixels (320x480) while the high end phones are pushing 384-410 thousand pixels. Even the Incredible and Evo don't feel as smooth as the Aria. The iPhone is smooth because its entire UI is GPU accelerated. Once GPU acceleration is enabled for the Android UI (think Gingerbread, 3.0) everything will be much smoother, especially on high end phones with nice GPUs like the Droid X and Galaxy S. The Aria won't even be getting Android 3.0, so its days of feeling smoother than the high end phones are limited.

For what it's worth, I have LauncherPro installed on my Captivate and live wallpapers disabled and everything is very smooth and snappy. The GPS issues are my only complaint right now, but I think it's a software problem and Samsung will come through within the next month or two. After playing with my Captivate for a week, I picked up the Aria and its screen seemed dull and extremely TINY. Web browsing, gaming, and watching videos are all a million times better on the Captivate. Basically, things that tax the CPU or GPU a lot are where the Aria chokes.
[Galaxy S I9000 General] jakers:
Hey guys. Got an aftermarket charger after my original gave up on day one and i didnt want to have to send everything back. When i plug the phone in the scren becomes un responise, but the hardware buttons stil work. Can anyone explain this? obviously i ned to try a diferant charger, specificaly for the galaxy but how can the charger stop the screen working? Many thanks.
[Galaxy S I9000 General] nandihno:
Yes the same thing happened to me,,i took the charger back..and got a proper one
[Galaxy S I9000 General] AllGamer:
just for reference, the Black Berry 9600 chargers are compatible with SGS 9000

i bough one for car use
[Galaxy S I9000 General] JaY_III:
So are the moto chargers.

My car charger is an old razor v3 mini-usb with a mini-usb adapter.

My wall charger is an old Razor v9m charger.

Never tested a BB charger as i have always charged mine with the moto ones that were already plugged in
[Galaxy S I9000 General] AllGamer:
yup i also purchased a mini usb to micro usb adapter to use my old Moto chargers with my SGS
[Galaxy S I9000 General] ssj4Gogeta1:
The same happened with me while using the stock charger in a train. The capacitive touch buttons and the screen stopped working, but the hardware buttons were working. So I plugged in my laptop and used a USB cable for charging it.
[Galaxy S I9000 General] Beards:
Never heard of this before....

I've not come across a charger that does not work.
[Galaxy S I9000 General] jakers:
The chatger works but the phone doesnt while its plugged in! my back button and menu button still work along with hardware buttons...... Weird... Allready ordered an official replacement
[Galaxy S I9000 General] Beards:
That will be the cable that has issues.

Pity you couldn't have tried another cable.
[Galaxy S I9000 General] Tim182:
I am using a nokia car charger, also works fine. Blackberry didn't work for me
[Galaxy S I9000 General] jakers:
Yeah i know the cable causes the issue but does anyone know how? obviously other after market chargers are ok... Phone charges fine too, just cant use it when charging...
[Galaxy S I9000 General] AllGamer:
i'm using After market chargers too, but i have no problem

my car charger is using a BlackBerry 9500 charger (2A)

an in my PC i use a Motorola sync/charge USB mini + micro USB adapter to make it compatible with SGS 9000

they all work fine

i have not even unpacked my SGS usb cable that came in the box
[Galaxy S I9000 General] TDO:
Is any of this chargers really recognized as charger (charging with more than 500mA)?

You can easily verify this with the app "OSmonitor".

IF you see this: "USB Power: Online and at AC Power: Online" everything is working as it should. But if you see "AC power: Offline" your phone thinks the charger is a pc and it will only charge with 500mA.
[Galaxy S I9000 General] Beards:
The only problem with software informers here though is for those that have the problem and the screen locks up whilst being charged the software is of little use.
[Galaxy S I9000 General] TDO:
This question was not for people having a faulty charger but for the ones claiming that they have a functioning charger!

If the charger is not really recognized as charger it is useless for navigation. As the Galaxy S need more than the 500mA while navigating (with GPS).
[Galaxy S I9000 General] AllGamer:
yeah, minimum you need a 1A (1000mAh) charger

that's why i prefer the 2A chargers, it gives just enough juice to actually charge the battery, and use GPS+3G+WiFi+Bluetooth

else the car charger will not even be enough to power all those, and it will still consume the battery power.

that's from experience from my HTC phones
[Galaxy S I9000 General] rod90:
I bought a Sharper Image Retractable USB kit that has adapters for most of the USB sockets out there. But the Micro USB that came with the kit fails to work with the SGS, the retractable USB cable is set up like an extension cable which works fine as an extension cable but putting on the adapters dont work.

How can i test the front camera?

Installed Fring already, but cannot find the setting to switch to front camera.

Any other free app can let me test the front camera?>

Thanks
[Galaxy S I9000 General] andreas_k:
Yes, standard camera app. On shooting mode select "Self shot" :)
[Galaxy S I9000 General] wang1chung:
I noticed the same issue with fring. I am assuming they are going to release an update for it with an option to switch between cameras.
[Galaxy S I9000 General] brunes:
Yeah I actually contacted Fring support about it, they were not aware of the bug until I told them, they are supposedly working on a fix.

Wow, that was really well written. Bookmarked for future reference, and to share in other forums or blog posts/comments :)
[EVO 4G General] afazel:
WiMax carriers wouldn't necessarily have to carry dual-mode for voice. Why couldn't they just use a VoIP technology? Latency on WiMax in good coverage is low enough to sustain a stable and high-quality VoIP call. Even SIP traffic through a carrier-specific VPN tunnel would probably be sufficient to handle any voice demand.
[EVO 4G General] Geniusdog254:
That's true, but like I said, there's no STANDARD for voice on WiMax. Carriers can implement their own, but it could vary between networks. As far as the IEEE standards are concerned there is no voice. On the other hand, LTE has a standard across networks.
[EVO 4G General] Aridon:
Spectrum doesn't mean **** if you can't get connected inside. Many, many places this will be a huge issue. Even if you can get connected the signal loss will hamper bandwidth so again whats the point?

LTE is going to be the clear winner. Clear will eventually switch and the only losers will be handsets like the EVO and Eipc for anyone that is still using them with 4g in mind because inside of a couple of years I doubt they will continue to work (4g).
[EVO 4G General] Geniusdog254:
Youre spectrum point is only valid in the US since in other regions LTE is on a higher freq. Plus my spectrum points were all about LTE. WiMax is currently using 10Mhz channels too. I was saying that Clear's FDD-LTE trials will use 40Mhz channels. Their TD-LTE trials will be using paired 10Mhz channels for 20Mhz total.

Also, if Sprint builds the network properly (ie densely enough) then you won't have connection problems. That's the catch here in the US & why LTE will win here, but in other regions its still a fair fight.
[EVO 4G General] edtate:
While it's nice knowing our phones are just that little bit more "future proof",by the time any carrier has respectable lte /wimax2 networks, the majority of us would have already been upgraded to the next big thing which would have those capabilities out of the box.
[EVO 4G General] cLOUDFAn:
from what i remember

almost all the carriers in the world (80+%) are planning to use LTE

sprint seems like the only major one that uses wimax (and planning to convert to LTE )
[EVO 4G General] Geniusdog254:
Actually Yota in Russia is a major WiMax/GSM carrier & several telcos in Japan (can't remember names) are both behind WiMax. There are also several in India, which is one of the larger markets in the world.

Both will coexist happily I think. A major part of Clear's LTE trials this year are to test performance of providing both LTE & WiMax over the same channel. Another thing to consider is topography. I don't remember where I saw it but I saw a graphic that showed the range of 2.5 WiMax vs 700 LTE. Obviously the LTE provided better range, but depending on the topography WiMax can be a better option because it provides better service in dense urban areas if the network is planned right (less than 15dBm of loss from structures is a good level, 19 or 20 is the norm)
[EVO 4G General] crakerjaks:
wimax in ugunda as well cool story, anyways I have a Q, the dual voice data thing, are you saying wimax wont support making calls and surfing net at the same time in the future and LTE will?
[EVO 4G General] Geniusdog254:
No, WiMax & LTE both support simultaneous voice & data. LTE supports it the right way, just like WCDMA/HSPA support it now.

WiMax supports it but only because it requires a dual mode radio (one for voice/EvDo, one for WiMax)

What I said means that if you have JUST an LTE connection (IE no 2G/3G/etc fallback network at all) you can make a phone call. If you have JUST a WiMax connection with no fallback network you can't make a call.

IE: WiMax is currently a data only network, like when T-Mobile launched their 3G network there was no voice coverage. Sprint could add it down the road (and probably will, if they don't switch to LTE) by using as the other poster said one of several possible VoIP options to deliver calls. LTE also uses VoIP as their call standard, since its a completely IP based backbone network like WiMax.
[EVO 4G General] pflatlyne:
Thats true. Wimax has rolled out in Salt Lake City and its pretty much useless. It works on the main streets but as soon as you go off those,it fades fast. Inside buildings,you can rarely get a signal. It may get better,but right now the line of sight characteristics of the 2.5ghz signals are really a problem and Im not yet convinced that they can put in enough towers to overcome it.
[EVO 4G General] rori~:
Great OP !

...as an european, I am waiting for a nice LTE device :)
[EVO 4G General] werxen:
Great post so far - enjoying it very much.

What are your thoughts on the current Sprint WiMAX? Do you guys think the cities that are live will be kept the way they are? I remember reading somewhere when most cities are live Sprint will go back and improve the older cities so people can get more of a consistent signal. Its not WiMAX perse, its Sprint ATM.
[EVO 4G General] Award Tour:
Anybody know the energy efficiency (on the users end) of LTE, WiMax, and even HSPA+? WiMax is great even in it's US infancy, ~100 ping + 6-10Mbps down for me, but it's so much more energy inefficient compared to 3G that it's only something that I turn on if I want to tether and can connect my EVO to a power source.

Now compare that to the iPhone 4 which I also have. I don't think it's a HSPA+ phone but it can still take advantage (albeit not fully) of it if the signal is there. So I end up getting around the same ping and 4 Mbps and change on the down link. Now the thing that interests me the most is that it doesn't seem to effect the battery life as much if at all. So I actually get to enjoy the increased speed. Of course, I don't know by how much, if at all, this is effected if the phone is HSPA+ capable (20Mps+).

I know WiMax is very similar to WiFi, and we all know that WiFi is a lot nicer to the battery than 3G. So is WiMax's battery hogging maybe related to the poor coverage and can possibly be significantly improved when there's more coverage? Is anybody really, really near a tower and feel a difference?

What about LTE? Anybody from Sweden (or any other place that has LTE rolled out) here?

Edit: Now that I think of it, wouldn't LTE be better in this regard since it only has to power one radio for both voice/data?
[EVO 4G General] werxen:
Its the phone not the network, really. ****ty battery life only gets ****tier when you are searching for a weak signal.
[EVO 4G General] Award Tour:
Yeah, but you have imagine that there are battery differences between LTE, WiMax, and HSPA+; just as there is between "2G", "3G", and WiFi
[EVO 4G General] benoitb85:
In Europe at least, LTE is pushed by a much stronger lobby and will be THE 4G standard.

It's already being deployed in Japan as well and will be in the USA. I think this is the next worldwide standard, so the prices will go down and that will leave only minor networks to Wimax as a mobility technology.

Wimax is already used in some places as a fixed internet acces (no mobility, only fixed wireless).

In France, I don't see LTE happening before 2013 because there have been many investments in the WCDMA networks so they will use HSPA+ to push and perfect the 3G network before eventually switching to LTE.
[EVO 4G General] Fightspit:
I found in the International Telecommunication Union (ITU) website a diagram about different telecom generations:

From: http://www.itu.int/ITU-D/imt-2000/Revised_JV/IntroducingIMT_item3.html

So the WiMAX IEEE 802.16e (and f) and LTE (3GPP Release 9) can be considered as "3.9G".

The ITU has selected two technologies for the 4G (IMT-Advanced) which are the

WiMAX IEEE 802.16m

and

LTE-Advanced (3GPP Release 10)

[url=http://www.3gpp.org/ftp/Specs/archive/27_series/27.007/27007-a00.zip](1st Rev. zip file)[/url].

I would add also that Qualcomm who is the inventor of the CDMA technology may prefer LTE-Advanced (3GPP Release 10) over WiMAX IEEE 802.16m.

Here, a pdf presentation about the benefits of the LTE-Advanced from his website:

http://www.qualcomm.de/documents/files/lte-advanced-benefits.pdf

[EVO 4G General] TeknoJnky:
I think the worst part of 4g-wimax/lte is the dual radio/dual networks.

It really sucks in an area where you get partial coverage and it bounces back and forth between 3g and 4g (getting different ips and interupting any data connections in the process).

I think eventually I will switch back to att or whoever has the best hspa+ at that time, simply due because of dual radio/network annoyances of sprint/wimax etc.

Recently, Qualcomm wins LTE spectrum in India.

From: http://www.techeye.net/mobile/qualcomm-wins-lte-spectrum-in-india
[EVO 4G General] dallashigh:
The voice standard is a really small point. As others have mentioned, WiMax can use VoIP just as LTE will. The most significant benefit of One Voice will be phone portability (using an AT&T handset on Verizon, for example). This will be good for consumers, but I'm sure the carriers will find a way to lock this down. The only other benefit is cheaper equipment.

Verizon has already stated, although I can't find the source ATM, that they will keep their CDMA network operational for a long time to come (until at least 2020 from what I remember). So again, in that sense they won't see a benefit anytime soon. I'm sure AT&T will also keep their GSM network up for a long time. I mean, look at how paultry their 3G coverage is. You think their LTE build-out is going to be much faster?

And let's not forget T-Mobile. They are pretty much set on HSPA+ for the foreseeable future. They probably won't make another upgrade until 5G :p

In the end, though, none of this really matters. Because no matter which technology is superior, be it technically or financially, no one really knows which one will 'win'. Only time will tell.

[EVO 4G General] willhang:
some questions after reading the post

Great article, both well-written and informative. Got some questions based on my limited knowledge on both technologies:

1) Intel, a big backer for WiMax has decided to drop their support for WiMax development in many markets earlier this year, how will this affect the adoption of WiMax as well as competing with LTE?

2) As mentioned in the article, WiMax is a near perfect technology for back-haul applications, however, I believe WiMax used to has line-of-sight and base-station hand-off issues on mobile devices. Have these been resolved in newer WiMax standard revisions?
[EVO 4G General] Geniusdog254:
Possibly it could affect adoption in new markets, but in places where it's already build out that won't have much of an affect IMO. Sprint is clearly dedicated on building out WiMax even if it does go to LTE as well. For instance YOTA, Sprint, and I forget the name of the big Japanese WiMax carrier aren't going to be switching right off just because Intel dropped backing in some markets.

That is only with the first commercial WiMax revision mostly (I think its 802.16d, but I'm not totally sure on that one). 802.16e is the revised mobile standard that Sprint uses. It resolves the station hand-off issues, however there are still some line of site issues in some setups. 802.16m (WiMax2) should totally resolve all those issues, I think.
