I've found changing your kernel makes more of a difference for me, since I tend to do most modding on my own anyway.
[Galaxy S II Q&A, Help & Troubleshooting] pileot:
Where can i learn about modding roms? Usually i find im doing the same things to the roms i download, remove bloatware, install apex, install my own calendar and other widgets... If im already removing the differences then why bother changing roms since they are the same?

Where in Canada are you located?
[Galaxy S II Q&A, Help & Troubleshooting] pileot:
Alberta, why?
[Galaxy S II Q&A, Help & Troubleshooting] ctomgee:
Just searching the forums, dude. I had to do all my own legwork learning how to decompile .apk files, how to then tweak/edit them, then recompile them... Along with how to use smali/baksmali. There are a bunch of tutorials out there in the Theme/App section, as well as the development sections.

Just start somewhat small; do some searches for "APK Edit" or "APK Manager". That should give you something to start with. Once you have a grasp of that, you'll find other stuff just ends up in your lap as a result.

Edit to add: as a result of what I've picked up, I've found I prefer Samsung stock firmwares that I tweak to my own liking over other ROMs.
[Galaxy S II Q&A, Help & Troubleshooting] pileot:
Well back to the root question: Main difference between the many, many different versions of stock ICS. What kind of stuff do they change? Whats so different between WXLP7 and LPDFG, for instance?
[Galaxy S II Q&A, Help & Troubleshooting] kilometers4:
I'm on the same device and live in bc and i'm on mugld3 modem, and it's pretty good for me
[Galaxy S II Q&A, Help & Troubleshooting] ctomgee:
Unfortunately, Samsung doesn't publish changelogs. So the only way to know is to try them both out yourself...

Or I guess you could wait until someone who already has tried them both out and noted all the changes reads this post and responds.
[Galaxy S II Q&A, Help & Troubleshooting] ctomgee:
I think he was asking about the overall firmwares, and not specifically the modem.
[Galaxy S II Q&A, Help & Troubleshooting] pileot:
I was kinda hoping for the latter since my unexperienced eye didnt notice anything doing the former.

Didnt know sammy didnt provide changelogs, that kind of sucks. Oh well, was worth a shot i guess.

Guess this thread wont go anywhere since theres no tangeable proof one way or the other of any differences. Thanks for the patience with me anyways XD

Hello Dear Xda Community ^_^

finally im able to upgrade my phone from a HTC Desire to something better... But i can´t decide what to get : HTC 1 S or the Sony Xperia S

i need a phone with good cam so:

first of all the software is not important for me i will run MIUI on it so HTC Sense is not important for me

pro Xperia S:

-dedicated camera button

- RGB Led

-Design

-720p Display

-highest dpi

-Normal LCD+Bravia Engine

-Hdmi output

-USB OTG

-32 GB Storage

negative Points:

- much thicker then the One S

-"only" a S3 processor

- smaller community

- cam software not that good

now the One S:

PRO

- Newest S4 processor

- better cam software (sense based miui roms)

- much thinner then the Xperia S

- its from HTC ( i never had ANY problem with my Desire and the Desire is still an awesome phone with the greatest community on the block after 2 years!)

Negativ

- LED Only 2 colours

- Pentile Matrix ( not that good i heard... )

- lower resolution

- only 16 gb storage ...

- i read that the one s has some build issues that the case has some problems

- no USB Otg

- no HDMI (yes with an adapter but then you can´t plugin a keyboard or something like on xperia s only with bluetooth @ one s... )

i really don´t know what phone to get ...

bot cost about the same here in Austria 360- 370 €

no fanboy comments pls

htc one s

hi,

the decision is very simple if you want a more faster procesor which is beating even the quad-core htc one x and gs3 in benchmarks go for the HTC One S....

it has the best processor in the market

and as for the pixel.... seriously anything above 200ppi is not visible to the naked eye(even less i guess)

even i own the HTC one s.... and it is amazing thought the camera is above par nothing wonderous.....
[Android Q&A, Help & Troubleshooting] sharik2009:
Go for Xperia S...

Hi,

Take the Xperia S because I had both devices in hand and I've now decided for the Xperia S .. S4 processor or not with ICS is the Xperia S Simply Perfect!

Display for me the best display on the market .. (the HTC One X: also has the best display)

Processor comes with ICS until full speed.

Design is class .. Well the HTC S is one small but when I think that in hand, I do not have a wow effect!

Take the Xperia S.

Best Camera..

Best display

Processor is very good.

:good: :good: ;)
[Galaxy S I9000 General] TVwithParents:
Please help:

I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.

The problem: My signal keeps on going out at regular intervals.

I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.

Tried all of the modems I could lay my hands on. Nothing works.

But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.

It has turned into an OCD where I keep checking my signal.

This does not happen when I'm back home and then I'm back to getting good signal.

Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?

Question: What could have made this mess to my signal reception? How can I solve this?

No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.

Also, sometimes the 3G would work even without the signal.

Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.

As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.

I'm on Vodafone India.

Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?
[Galaxy S I9000 General] kkipsy:
maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.
[Galaxy S I9000 General] DD-Ripper:
When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Sent from my GT-i9100 equipped with Grenade Launcher and Remote Explosives :D
[Galaxy S I9000 General] TVwithParents:
Thanks, let me try it out.

Where is the network changing option to GSM only in ICS?

Okay, I guess it's the 2G mode.

Is going to 2G mode my ONLY option? :(

How can I fix this and get back to using 3G?
[Galaxy S I9000 General] TVwithParents:
Update:

Changing to 2G mode fixed the problem. BUT...

I have a few questions now:

I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?

I remember reading somewhere that going to recovery and changing permission helps this.

Anyone knows how to change the permissions so the signal fluctuations stop?

I have done a lot of reading on XDA but I haven't noticed an issue like this.

CM9 guys, anything please...
[Galaxy S I9000 General] DD-Ripper:
I have the same issue mate...using 2G is the only option to get signal without any problem.

The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).

You got two options to fix this issue:

1. Change your Network Operator

Or

2. Settle to another location where 3G signal is fully available

Sent from my GT-i9100 equipped with Grenade Launcher and Remote Explosives :D
[Galaxy S I9000 General] TVwithParents:
Both the options look impossible for me at the moment. :(

I will start living with the hope that the operator brings us some decent 3G signal here.

Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:
[Galaxy S I9000 General] slaphead20:
Complain to your provider, very loud!
[Galaxy S I9000 General] Apurv24:
:good:Ditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..

Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location
[Galaxy S I9000 General] TVwithParents:
I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.

Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".
[Galaxy S I9000 General] hencke:
I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).
[Galaxy S I9000 General] thatdefault:
If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.

[fix] An easy way to solve the screen flicker with just a scotch tape

Pictures are dead but the claim is that scotch tape on the WiFi antenna solves the flicker (some disassembly required). This claim is refuted, but seems to work for many.

[Nexus 7 General] _dan:
Can you take a video? I haven't heard anything like that. If anything it sounds like a hardware problem.
[Nexus 7 General] soccerwuedo5:
My wife and son are asleep in the room so I can't do a video. I found another thread about the One X getting an immediate update to cure screen flicker. I'll probably talk to the Googlers about it tomorrow, but I wanted to post a thread to be available for future queries.
[Nexus 7 General] Brac20:
It seems to be a common issue with Tegra 3 devices. HTC fixed it pretty promptly so I expect Google/Asus will get it fixed even soon if it does turn out to be a common problem.
[Nexus 7 General] sulfobus:
This is an issue with Transformer Prime as well, maybe Nvidia still hasn't fixed their drivers. It has come and gone with different firmware updates, most recently it's back again... Seach for "transformer prime screen tearing" for videos of it. Does it look similar to what you saw?
[Nexus 7 General] soccerwuedo5:
So the connection is the Tegra 3, then. Good to know.

My issue is not like the screen tear. Mine is the entire display flickers like it was backlit by a candle. I'm using Thomas Edison's tablet from the 19th century.

Also, it ONLY happens on page load in Chrome and with brightness below about 10% on the slider. I'll talk to Google today and relay what comes from that.
[Nexus 7 General] qoncept:
Why don't you just exchange it?
[Nexus 7 General] dlwoodjr:
Sounds like a possibly defective backlighting module... I'd exchange it.

Don
[Nexus 7 General] Brac20:
It sounds very similar to the HTC One X issues which were fixed by a software update. It's hard to say without seeing the screen flicker though as there seem to be various screen issues that people refer to as "flicker".
[Nexus 7 General] rushless:
While you are at it, test if USB storage works on your N7 :)
[Nexus 7 General] AndroidInsanity:
The HTC One X had the same problem.if not worse. Flickered on any brightness level on a grey background.but HTC fixed it so it is a very good chance it is software issue with yours. Give it a few months first?
[Nexus 7 General] Multisaft7:
Is that really a Software issue? Because i am Order the nexus 7 from germany and think that There is the Support to Google Not good Because of no official release there

I think its problem with ICS/Jelly Bean for tablets

[Nexus 7 General] sahaskatta:
Does your Nexus 7 from google io take an extremely long time for screen rotation? I picked one up at the conference and did not open until today after the event ended. My unit sometimes takes as long as 30 seconds to rotate from landscape to portrait or vice versa.

FYI I have not tweaked or modified this tablet in any way. Just performed the software update after I was prompted to do so after setting it up for the first time.
[Nexus 7 General] adamhlj:
Lets hope thats all it takes.
[Nexus 7 General] Masssy:
I personally do not own a Nexus 7 yet. However is it really 100% it is a hardware error? Sure it does affect the screen only when WiFi is on but that shouldn't mean that it has to be the signal etc. that disturbs the screen.

It may be a driver conflict or some other things that makes this occur when the WiFi chip is working. I'm no proffessional at this stuff but from what I've been reported it seems like it could be either a hardware or a software problem.

On the other hand people have reported that friends units etc. are working. Bad eyes or perfect conditions could make the problem seem less harmless when you take a look at another device which means every unit may have the problem and not just a certain batch.

What do I know, however that's my thoughts on the problem.
[Nexus 7 General] kenyee:
You mean this?

http://www.youtube.com/watch?v=W8wWCAkjZHA

If so, that looks like flickering from the Tegra GPU being used to scroll the screen.

The wifi flicker we see doesn't require any movement at all. It's simply reproduced with:

- low brightness screen setting (I think high would do it to, but don't like mine that bright)

- you have a *LOW* wifi signal (one or two bars in the icon up top). The higher it is, the less the flicker. I'd actually say if you have a strong wifi signal or don't download much (e.g., you play games a lot, read books, etc.), it'll be a non-issue for you.

Still feels like a hardware issue to me...they can probably work around it in software at the expense of wifi speed or range (tell the chip to use less power or cut it back to 802.11b speeds instead of 802.11n)...

I'm wondering whether I should return mine too...this one has a good screen so I'm hesitant...
[Nexus 7 General] qwerty123321:
What is with you people thinking that it is hardware related!? If an app on Play store (Screen Filter) could fix the problem what makes you think google cant?
[Nexus 7 General] potentiality:
Anyone try the 0% workaround to see if hypothesis correct? (Why some say they don't see it)

Why return it if it is indeed hardware. It wont be fixed until a newer revision. Which will take a few weeks. A few weeks after our exchange policies at most places. :(

Will someone at Google are Asus please just admit what it is publically?
[Nexus 7 General] Nascar Dog:
That Screen Filter app does not fix the problem it just masks it by darkening the screen.

It's like applying tint to the windows of your car. The brightness level does not change but the screen appears darker.

The app also causes other issues like banding and APK file installation problems.
[Nexus 7 General] adamhlj:
The problem with that app is that it doesn't affect the soft keys, so they are super bright if you turn the app on. At least, that is what I have noticed. It does reduce the darkness of the screen, so that part is successful. Just the soft keys at the bottom of the screen are unaffected.
[Nexus 7 General] kenyee:
Only about 10yrs of hardware/firmware experience doing modems/network routers/data loggers, etc. :rolleyes:

Hardware problem can sometimes be worked around w/ software...doesn't make them not hardware problems...
[Nexus 7 General] xceleration:
Is there any acknowledgement about this issue from Google yet? Also, has anyone with this problem actually returned their unit and received a unit that doesn't have this problem? I'm on the fence about exchanging mines at the moment, unless it's confirmed to be a software issue. Everything else about mines is fine.
[Nexus 7 General] Henrock11:

Is this the flicker issue in question that everyone here is experiencing?

I have an issue where I see horizontal lines on white backgrounds like the old t.v. screens when trying to load a webpage or when loading a thread on the xda app. Its subtle and will only do it for a half a second or so.
[Nexus 7 General] sm0kincamel:
Noticed the screen flicker last night while I was reading a book....thought maybe it was just an issue with auto brightness settings. :confused:

---------- Post added at 09:21 PM ---------- Previous post was at 09:16 PM ----------

exactly, except mine wasn't that constant....only every few minutes it would flicker once or twice.
[Nexus 7 General] qwerty123321:
No it darken the screen in a different way than the default brightness control . I truly believe that Google could use a similar method darkening the screen thus eliminatiring the problem

---------- Post added at 02:31 AM ---------- Previous post was at 02:22 AM ----------

Very true .. but that's what I meant Google musb be able to work around it if an app on play store could .
[Nexus 7 General] SDO1000:
It's not fixing it. It's masking it. I'm assuming people are turning off their auto brightness, cranking it up a bit, then turning on the filter. That'll run the battery down faster when we really shouldn't have to.
[Nexus 7 General] wynand32:
I think many of the LCD issues like colors washing out after watching video, screen flicker, and those sorts of things might very well be related to the Tegra 3 power-saving screen technology that screws with color and brightness depending on what's being displayed. I saw many of the same kinds of issues on the Transformer Prime, Toshiba Excite 10, and Toshiba Excite 7.7, all of which of course use the Tegra 3 (and all have different screens).

Here's Nvidia's description:

If it's related, it's definitely software and fixable via a firmware update. I think everyone with a Twitter account should send a note to @NVIDIATegra and ask if this PRISM tech might be screwing with the performance of the Nexus 7's screen.
[Nexus 7 General] potentiality:
Its the back light. Not the screen. So I'm pretty sure its not related to the Tegra 3. Has anyone turned theirs to the lowest setting_ ? Again, I'm not experiencing any issues when its like this (it won't flicker because it already is the lowest). This still would backup it a hardware issue. Like a misused cap or something that is sensitive to the power draw of the wireless at lower setting.

This is why I HNK its all current units.

Again to truly test your unit.

1. Poor/far wireless connection. Like 80 dbm or higher.

2. Brightness setting under 30%. NOT AT 0%.

3. App that accesses the Net a great amount. Easier to see with lighter backgrounds.
[Nexus 7 General] kenyee:
Nope...it's a pulsing of the entire display (aka, the backlight), and more obvious if you have *low* wifi signal so the wifi antenna power is higher. That's why it seems like it's a hardware issue...

It's actually a droop in power (dimming) then brightening (surge) so that's another reason it seems like a hardware issue.

I think it needs extra capacitors on the backlight power circuit as well...just wish they'd say if they fixed this and what serial# the fix is in so we can stop playing exchange russian roulette:eek:
[Nexus 7 General] akiootsuka:
Seems to becoming worse.

For the past few days I've been running my nexus 7 at 50% brightness.

Last night, However I was in bed reading and my wife decided to be a grump and demanded I turn down the brightness, So I did.

Then I realized why I had set it at 50% the flicker was terrible, so bad that I stopped reading and tried other applications.

I can't believe google has yet to release an update for this or a patch of some sort.

Has anyone else contacted Google CS?
[Nexus 7 General] threi_:
Tried it and i can't reproduce the problem....*shrug*
[Nexus 7 General] Nascar Dog:
You need to have a weak Wi-Fi signal to get it to flicker.
[Nexus 7 General] threi_:
Well i wasn't in an area that had a very strong signal, but i will try again.
[Nexus 7 General] boneskid1:
Well I just got off the Phone with a Google rep and he said that there is actually a loose solder joint on the back of the LCD and the Wi-Fi antenna is connected through that circuit and the joint is not properly insulated so when we use the Wi-Fi some of the power from the circuitry escapes to the LCD. I plan on taking my n7 back as it does display the screen flicker. He also said there is no way to identify the faulty tabs by then/n or the check number. But I would think that the production line would be numbered so they could tell which devices had the bad joint.
[Nexus 7 General] SDO1000:
Guess I'll be making a trip back to Sams club. :(
[Nexus 7 General] boneskid1:
Sorry man didn't Mean to Disappoint but most of us here Want a flawless quick device and so far only the quick part has been displayed
[Nexus 7 General] SDO1000:
No problem! At least we know now that it's hardware. This was the major issue with mine. I still have a week or so before it has to be returned. Once I do that, I won't be re purchasing unless I hear that the issue has been resolved.
[Nexus 7 General] boneskid1:
Yeah I might wait a week or two after returning mine' but the guy I talked to claimed that a devices shipping out from Google right now are the fixed version and that he could send me one but since I ordered from office depot I have to go though them, which I kind of back wards because it is Asus, and google,'s device and I can't even send it to them to get it replaced
[Nexus 7 General] just lou:
Me neither. I've tried every theory posted. I ran Maps with almost no wifi signal by removing my router antenna. I used various brightness settings from 5-100%, including Auto. My screen is fine. I got my N7 10 days ago from GP Store, so it's an early one too.
[Nexus 7 General] scootle74:
