[Android Software Development] EQUANCY:
I have a tablet named Wits A81-E C version,

but I have problem with firmware.

WitsTech puplished an android 2.2 firmware for A81 oldversions.

There is two version:

a81_a(android2.2) and a81_c(android2.2)

Mine is C but with that firmware you don't have sound and GPS,

and A version has very quiet sound ( without 3.5 mm jack support ) and no gps.

C version faster than A version.

Then I've installed Android 2.1 version from witstech page.

Everything works fine also sound.

So,

My question is:

Is that possible to extract sound driver from 2.1 firmware an inject to 2.2 and recompile.

New A81E series has screen adjustment problem with my device, which I mean is screen is not centered and I think it's not possible to fix.

But importing driver from 2.1 image is very possible I think.

But,

I have no experience about Android or linux systems.

Need helpful people's support.

Thanks,

Regards.

I mean WTF? I have almost full bars and 4g symbol but I can't get online or the market will say data connectivity is fuked. Or sometimes it's just insanely slow.

What gives?

I will try it a few times and it works perfect and it's like this everywhere in town.

You are not the only one.
[T-Mobile LG G2x] samson_420:
Good to know:rolleyes:

This blows, WTF. . . . My HD2 flies when this thing just croaks. It just hangs and waits for who knows what.
[T-Mobile LG G2x] dalepa:
Welcome to 4G.... The G stands for Gullible.

Seems that when the 4G icon is displayed means that you have a 4G signal, however I don't think means you have a connection.

When I do get a 4G connection, life is great.

It appears to me that there are several bugs switching back and forth between wifi/4g/2g that is causing many issues.
[T-Mobile LG G2x] samson_420:
This is horse crap. The connectivity rotts, I meat rotts. . . . .The best speed I got so far was 3,000bps. But my other phone is at a constants 28.

And the worst part is not the speed, it's just spotty. Sometimes I get like 700, this is not cool.
[T-Mobile LG G2x] diablos991:
I have never had this issue.

I rarely ever lose 4g and I constantly have fantastic speedy connections.

I have never had a phone hold a connection as well as this phone.

(iPhone, BB, Nexus One, HTC HD7, etc..)
[T-Mobile LG G2x] samson_420:
Word, I never lose the 4G symbol. Yet, there is no connectivity.
[T-Mobile LG G2x] dj75728:
Did any of you guys happen to skip the initial setup for your phones? That has been found to cause a lot of problems relating to signal and connectivity. Try factory resetting and NOT skipping the initial setup if you skipped it before.

Edit: My phone is running great now, but once I did skip the initial setup and it was being really wonky.
[T-Mobile LG G2x] samson_420:
Initial settup:/

I strongly doubt it. . . Just what I think.
[T-Mobile LG G2x] los0325:
Make sure T-Mobile is using the right internet for 2days they had blackberry web I noticed that while looking into the myaccount app
[T-Mobile LG G2x] lilbuddhaman:
I had an issue as well.

T-mobile had set up my device wrong, they put me under a "unlimited text / talk" plan with a "mobile wifi data only" option, ie: zero data on 3g/4g.

After a 15min phone call to support it was corrected but as some people know already, the promotion I'm under (and what is being advertised), which is the $79.99 unlimited text/data/talk plan, the data limit is 2 gigs a month.

Its 2011 ffs. 2 gig's is stupid low.
[T-Mobile LG G2x] piztol44pete:
I was using my G2X with no issues until today. everything that uses data connection is slow and times out. when i connect to a wireless connection it is blazing fast. I don't think i skipped the initial set up i don't see why i would but i am going to reset and do it again and see if it helps, Battery life is also terrible i have not been using my phone for much today and its is already at 20% and i unplugged it at 9am , my HD2 at this point is looking good.
[T-Mobile LG G2x] samson_420:
So strange, today the connectivity is real good(2k down) I also have SPB 3D installed and the battery is awesome so far. 6 hours and I am @ 69% with a lot of use.
[T-Mobile LG G2x] j0hnee:
I'm having this same problem and I'm pissed. Calling tmobile is a pain in the ass nowadays and I'm about to tell them to shove this phone up their ass!!!!
[T-Mobile LG G2x] samson_420:
My question is this: Will a new ROM(when it comes out) fix this BS?
[Vibrant General] jwleonhart:
So why is it that gps works on 2.2 bland 2.2.1 but not 2.3? Just wonderibg
[Vibrant General] brulee:
I believed this is because the devs don't have actual source code yet.
[Vibrant General] cpittman:
we need drivers and the only way to come about hose would be an official vibrant gb kernel.
[Vibrant General] jwleonhart:
Im no expert but... wouldn't a person like eugene be able to make the drivers it would work?

Honestly, how much smarter are the people at samsung than the people on this forum???
[Vibrant General] allthrottle:
I hope that was a joke.. the effort required to develop drivers for GPS without source code is immense for anyone that wasn't directly involved in the software development for the phone, hence no GPS working with 2.3 on the vibrant. The GPS in the i9000 galaxy s isn't the same as the vibrant, and there isn't a 2.3 rom leaked or released for the vibrant. That's why our 2.3 roms don't have GPS functioning.
[Vibrant General] xsteven77x:
Eugene told the vibrant community to proverbially suck it if I recall correctly.
[Vibrant General] reuthermonkey:
That's like me asking you to build an engine from scratch. I mean, you've probably been in a car. You may even know how to drive it. Maybe change out the washer fluid? Fill it up with gas? Maybe even change the oil!

So if you can do all of that, you should be able to design, fabricate, and build a fully functional, great engine from scratch... Right? It's a pretty important piece of a car - sure - but you work with cars every day!

Not trying to be (too much of) an ass here, but really. Coding drivers is a difficult, very time-consuming task. There's a bit of a difference between coding to directly interact with the hardware, and hooking into existing APIs and modifying existing code. Has nothing to do with smarts. It has to do with resources. Easy testing access to the direct hardware. Money. Time.
[Vibrant General] brulee:
I don't really know what's involve in the GPS drivers but I would think that if we get the source for 2.2.1 and make it work, it shouldn't be that that to make it work in 2.3. I am missing something here? I wrote up some linux drivers before, it's not exactly a sacred thing.
[Vibrant General] explodingboy70:
You're missing the point because you're not even seeing what your typing. No we don't have source for 2.2.1 but do you not see those first two numbers. This means that because 2.2.1 is still Froyo we didn't need to update the GPS drivers because they didn't change. Now we are talking about Gingerbread which is 2.3 and a completely new build.

Think of it in terms of windows. When Vista SP1 was released it meant very little when it came to hardware for those already running Vista. Now when Win 7 came out some of you drivers had to be updated. Some things didn't work right off and if you've purchased any hardware in the last 5 years such as a mouse or keyboard you've likely seen the sticker saying Vista compatible or Win 7 compatible.

Does any of this make sense?
[Vibrant General] mattb3:
How about this for a related and potentially dumb question. What's the technical reason why a vibrant 2.2 kernel couldn't be used with a 2.3 system. In the Linux desktop arena, a huge variety of kernels can be used with a huge variety of userland.
[Vibrant General] funeralthirst:
then you should have no problem getting us gps on 2.3...
[Vibrant General] STiGLOGiC:
I would just like to say that you have made my morning. Thank you. ===================================================
[Vibrant General] brulee:
Thank you for your answer @explodingboy. I know when there is a new version of OS, most if not all drivers have to be ported over. You actually answer my question though -- you don't even have source for 2.2.1!

P.S. I am new on this forum and there is some rule here that I have to wait 5 minutes to edit my post. :-(
[Vibrant General] dcontrol:
Captivate must've gotten their leak because their GPS works
[Vibrant General] compuguy1088:
On 2.3? Can you post a link to this as proof?
[Vibrant General] geoffcorey:
The captivate users are lucky in that their GPS works with the i9k files. Its been that way for most if not all of the i9k 2.2.1 roms from Samsung.
[Vibrant General] compuguy1088:
I honestly don't get this. Hardware wise (excluding supported bands) the captivate and the vibrant have the same gps chip. The only difference is software wise: the vibrant uses one software/driver implementation, the captivate another (Which honestly makes no sense.....). In *theory*, the drivers/software implementation should work with our gps chip. Correct me if I'm wrong (Note: I've used the plumbob gps fix for the captivate with some success on the vibrant).
[Vibrant General] dligon:
its probably because the north korean samsung made the vibrant and the south korean samsung made the captivate and you already know they dont get along.
[Vibrant General] jwkj101401:
Re

Here's the confusing thing for me, we had gps for 2.2 after eugene made it work with the leak from the i9k. So now that we have a 2.3 release from Samsung what makes it different. Did gingerbread somehow make gps different. My point is that when we were first getting 2.2 roms gps came quick.

edit: Im not complaining just curious.
[Vibrant General] brulee:
Totally agreed with your assessment! There must be some hardcoded data for the Asian built version vs. North American. Would a binary diff give us some hints? But then if you don't have the source, you can't rebuild the damn thing!
[Vibrant General] VibrantThemer:
I'm not sure what the different is, but I found that I the gps xml files were stored in different directory.
[Vibrant General] VICosPhi:
Eugene used t959 froyo leak to extract 2.2 gps drivers and not the i9k
[Vibrant General] compuguy1088:
There are several ways this could be accomplished. One way would be to develop a clean room implementation, through a sort of "black box". Basically you would feed input into the box (AKA gpsd) and use the results to write your own implementation.

I seriously doubt this :P.
[Vibrant General] brulee:
Well, how do you get to this thing from the processor? i2c, local bus, memory map? A schematic would help.

BTW, can someone point me to how to set up a build environment for to start with?

[Vibrant General] jRi0T68:
Are you sure you don't have wifi enabled and it's not just using wifi? Nobody has gotten gps to work on any 2.3 vibrant rom yet, so you'd be the first, and a hero. I doubt it, though. No offense.
[Vibrant General] brulee:
That's a Europe based firmware. If you get it to work, at least, the map data must have changed out. And if it's that easy, you could just find the right map data for it. Sorta like the Europe map vs. North America map for Garmin.
[Xoom General] jiwengang:
My newly purchased wifi xoom.

Is it just my problem in hareware or there is some software update about it?

Basically everytime I switch to front facing camera, it freezes and black screen it shows.

Back camera is working fine, both video and picture.

Front is not, neither video nor picture.

Stock camera app.

If yours had similar issue and fixed it in some adb update on lib or other files. Please point me the way~
[Xoom General] kkwus74:
Mines working fine on the wifi version. Both the camera and videochat using gtalk. Hmmm... sounds like a hardware issue? Did it ever work?

[Xoom General] bballer71418:
^^ How good is the quality of your front facing camera
[Xoom General] kkwus74:
Obviously it's not as good as the back camera but it's OK for video chats. What do you consider bad or good?
[Xoom General] bballer71418:
I'm not.comparing it to the back just wondering if everyone's is a bit fuzzy
[Xoom General] kkwus74:
Yeah mine is alittle fuzzy too but maybe it's because of the pixels. It's the same on my gtab too with the front camera.
[Xoom General] Stone 13:
you need really good light for the front facing cam, it's only adequate in decent or low light.
[Xoom General] jiwengang:
thanks for info

I exchanged one. Previous one was hardware issue, even best buy geek square has to admit
[Xoom General] intensus:
Hi, thats happening to my right now, my front facing camera frezes and give me so me diagonal stripes with out working. Yours was a hardware problem? Or a SO library problem? Please need some light im getting crazy trying ti figure out what is the problem.

Hope u can se this and answer maybe by Direct Message.

Thanx
[Xoom General] wang1404:
Most likely the hardware issue. Front facing camera broken = nothing showing up. This should have never been a software issue. If it was a software issue, everybody would have noticed it by now. Thus, assuming your xoom is stock, theres nothing you can do to accessing the library without root.

[Desire Q&A, Help & Troubleshooting] sga101:
Hi all,

Have been having problems with my desire rebooting itself for a while now.

A few months ago, this resulted in the phone getting stuck at the first HTC screen. At the time, after searching the forums for an answer, I downloaded the HTC WWE ruu, and installed it with no problems, which brought the phone back to life.

So when the same thing happened yesterday, I thought I'd do the same thing again. I didn't have the RUU I used last time to hand, so I downloaded the latest one from shipped roms -

(RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00.32U_5.11.05.27_release_159811_signed.exe).

The update process started OK, but failed with error 152: Image Update Error

So I clicked on Recover, and followed the steps. When I unplugged the usb cable, I was presented with the white RUU screen, which showed:

BRAVO PVT3 SHIP S-ON

HBOOT-0.93.0001

MICROP-051d

TOUCH PANEL-SYNW0101

[7] USERDATA - OK

[8] SPLASH1 - OK

[9] SPLASH2 - OK
​

Partition update fail!

Update Fail!

I thought it might be a corrupt download, so I hunted down a few other downloads of the same file, but they all had the same MD5 - bae5f3e1bf9f7e2e7d47d5e51254103b.

Now I am at a loss, and any help you can provide would be appreciated.

If I could just get it back to sticking at the HTC screen, I could return it for a replacement (its still under warranty).

More information in case it helps:

Unbranded desire purchased from play.com last year

I dont have a gold card

Previous working android install was 2.29.405.5, installed by OTA update.

Phone is not rooted - have never attempted this.

Running RUU from Vista as an administrator
[Desire Q&A, Help & Troubleshooting] sga101:
SOLVED

Believe it or not, I managed to flash the stock RUU after placing the phone in a plastic bag in the freezer for five minutes.

The inspiration came from this post.

[EVO 4G Q&A, Help & Troubleshooting] nelce:
is anyone using CM7 having a problem with "news & weather"? my phone doesn't seem able to acquire my location to update the weather. whenever i refresh the weather, it'll say "acquiring location"...then "loading..." and then it says "no weather location available". i am also using an app called "minimalistic text" to display the weather on a widget and it can't seem to acquire a location to display either...anyone know what's going on here? if i specify a city (i.e., a "custom location"), then it will display the weather...otherwise it doesn't. my gps is working fine as well so i'm not sure why it can't seem to detect my location for the weather

any help would be appreciated! thanks!
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
I'm not having any issues with it. You have you location set?

Its working for me on nightly 40, just switched to 51 and still working.

Also using the minimalistic text widget, and it has my location and weather as well. Do you have it set in settings to acquire location by mobile

data, otherwise you'll have to have gps on.
[EVO 4G Q&A, Help & Troubleshooting] nelce:
no i don't have the location set. if i have it set to a specific location, then it works. if i want it to update depending on which city i'm in, then it doesn't work and says "no weather location available..."

back when i had the sense stock, i didn't have to have gps on..and every few hours, the weather would update on its own depending on which city i was in...
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:

No special settings under minimalist. Hit globals settings, and try checking define location. Mine isn't checked, but it still picks up my location.

yea currently i have "define location" checked...but then it makes me specify a location...so i did...and it works. but if i leave it unchecked, it doesn't pick up my location...and this is precisely the problem...cuz i want it to update depending on where i am...vs. specifying only one location...

weird that i seem to be the only one with this problem..cuz i didn't find anyone else with posts regarding this matter

[Droid Incredible Q&A, Help & Troubleshooting] hightech316:
I know after 2.2 Android completely handles task processing and task killers have no real affect, since the apps start right back up.

Does this differ with gingerbread? When I have task running in the background and my memory is only 144mb free, I hit the kill all on my task manager and I get 270mb. That 270mb slowly returns back to the 140's without me doing anything.

What is the best way to manage memory with gingerbread? Does Auto Killer Memory optimizer have any impact?

Ideas and Suggestions?

I have my phone and specs on my signature.
[Droid Incredible Q&A, Help & Troubleshooting] Deleted member 2776902:
I recommend not using a task killer unless you absolutely have to. Android runs different than windows. And having full RAM is actually ok. It kills off process to make room for the new anyway. Android 2.3 is much better about handling processes than previous versions too.
[Droid Incredible Q&A, Help & Troubleshooting] CBankord:
Don't use a task killer unless you have a misbehaving app. Android handles everything else just fine by itself.
[Droid Incredible Q&A, Help & Troubleshooting] brando56894:
There's no reason to use a task killer, especially with an Incredible since it has a lot of RAM. I used to use MinFreeManager with 2.3 on my OG Droid but that was because it had half the ram of the Inc and would kill off something as soon as it got pushed to the background. In Android (and linux/unix) free ram != good

[Droid Incredible Q&A, Help & Troubleshooting] k_nivesout:
There's not really any reason too, with gingerbread and froyo, android will automatically end tasks to free up memory if its needed. And since you're running cm7, you don't have any bloatware (which is usually what people are trying to deal with with task killers).
