[Galaxy S II Q&A, Help & Troubleshooting] EarlZ:
Wifi - Yes its weaker compared to the Iphone4 or any of the Netbooks I have at home, In a spot here the netbook can still hold and maintain the signal the SGS2 doesnt even see the router to be in range anymore.

GPS issues - I dont use the GPS that much so its a non-issue for me.

Display yellow tint - Biggest downside of this product, its supposed to feature a great screen (not perfect but great) lots of other quality control related issues on the screen.

wake up lag - I think all andriod phones have this wake up lag, but someone correct me on this. The S1 also had this after the 2.2 update.

overheating playing 3D games - I've been with 3 units and my first 2 phones barely heated up when playing games, this 3rd phone runs significantly warmer.

sound quality issues - S2 uses a lower end sound chip so this must be the main culprit.

battery life problems - totally subjective to the usage and expectations, Im getting great battery life my self, nothing extra ordinary.

Dont forget about the pink spot on the camera and video stutter/frame drop issues too :p
[Galaxy S II Q&A, Help & Troubleshooting] lynzoid:
Nothing subjective about weak battery - it's WEAK....

Only + point i can think about is a decent camera. But on mine it broke 2 weeks after purchase.

Korean trash.
[Galaxy S II Q&A, Help & Troubleshooting] Rytkonen:
My experience:

Wifi weak = Good enough for my use

GPS issues = nope

Display yellow tint = nope

wake up lag = You got to be kidding me

overheating playing 3D games = True it gets pretty warm

sound quality issues = Good enough for my use

battery life problems = Battery life is good

I have 4 friends with the same phone, and they are not experiencing these issues.

Positives:

- It is fast. It laughs at your iPhone 4 and Sensation.

- It has a big beautiful screen but it is still thin and lightweight

- Enough RAM (1 GB)

- Touchwiz 4 is super smooth and it is in my opinion better than Sense

- Very smooth web browser

- Good camera

Overall:

Best phone on the market at the moment.
[Galaxy S II Q&A, Help & Troubleshooting] ithehappy:
Well for me it is mainly the Web Browser (Stock only), I don't even turn my PC on for normal browsing anymore. Full Flash support is awesome. Hardware acceleration is great too.

Besides,

Video Playback

capacity is great too, it can even play 1080P MKV's, and that with subtitles, nice. We shouldn't forget the awesome 4.27" S-AMOLED Plus screen.

Having a

Noise Cancellation Mic

is very nice too, especially when you are in noisy areas.

What else? Can't remember atm, will edit post if I do remember.

Regards.

Ill-informed and racist - good work.

Pity you didn't manage a spot of sexism or you'd have had the hat trick.
[Galaxy S II Q&A, Help & Troubleshooting] Jimbojib:
The yellow tint was just a manufacturing problem, and if you bought a device now (new) it wouldn't have it.
[Galaxy S II Q&A, Help & Troubleshooting] EarlZ:
Ok if its not subjective to usage then anyone who cant reach 6days of battery life has a defective phone since I can get 6days with well over 40% of battery left. This is ofcourse taken from what you said.

See how others would comment about the battery life or screen, they have different feedbacks according to what their usage is.

Ex.

Someone who just uses the phone for call/sms will have insanely awesome battery life but someone who has wifi/bt/gps/HSPDA enabled 24/7 might with regular push and updates and uses this phone as an alternative to a netbook will only get between 6-10hrs of battery life.

Same goes for the people who dont see the yellow tint as an issue because they bought the phone not for its screen but for its phone features or just plainly accept the defects thus causing a low quality product.

Everything is almost subjective to the user.

Not being anal here but Id like for you to prove that with pictures that the new batches dont have yellow tinting, so that those who bought the initial batches that came out can send it so the service center and have it replaced.

Thats the problem, a lot of us assume that the 6 million figure released by sites is 100% accurate and even if it is we dont really know how much the return rates are but if they are indeed pretty low how come a few folks ( regardless of how few this ppl are ) have exchanged the phone more than twice..

Also a lot of people have been getting misinformation from forums claiming these issues to be "normal", with enough returns samsung will surely rectify some of it.

Think about it if samsung will silently introduce a new revised hardware with a significantly higher screen quality control ( including the total elimination of the yellow tinting, darker spots, white blotches and vertical banding ) and a fixed camera w/o frame drops and pink spots, a better GPS antenna configuration.. for sure those who claimed that they dont see the issue suddenly will see the issue if they know about revised hardware. Just saying but its gonna be a fact when this happens, not asking for perfection just asking for better quality =)

Then again the issues we see (aside from quality and manufacturing issues) are pretty much subjective to the user experience.

The positive thing about this phone is that its blazing fast! No other phone can compare but it also has a lot of issues and down sides especially the AOS bug when you have wifi and IM apps running, compared it to a 2.1 / 2.2 or 2.3.5 nexus reference device the N1 and NS outlasts the battery on this phone, heck even the iphone4 outlasts it when the AOS bug kicks in.
[Galaxy S II Q&A, Help & Troubleshooting] ithehappy:
LOL, Negative. Prove what you say.

If you are trying to spoil the mind of the old buyers, then that won't happen. :cool:

[Galaxy S II Q&A, Help & Troubleshooting] ghost77:
My SGS2 is only couple of weeks old , no yellow tint on it, can post pictures compared to my captivate later.
[Galaxy S II Q&A, Help & Troubleshooting] angelomaldito:
+1.

Battery life is proportional to use. Wi-Fi+sync = battery drain. Have been using Juice Defender Ultimate for a few days and it help to solve this as it turns Wi-Fi and sync on only then the screen is on and when it is scheduled to do so (for 15 seconds every 15 minutes in my case) in order to receive e-mails, updates, etc.

About the rest, well, no issues at all! Just perfect. :)
[Galaxy S II Q&A, Help & Troubleshooting] EarlZ:
Please post pictures as it will be a great news for those who are still waiting for a fix on this before sending it to the service center. Also post the kernels used after you guys post the pictures.. hopefully its still a 2.3.3 kernel :)
[Galaxy S II Q&A, Help & Troubleshooting] rockky:
I love web browsing on here but NOT with the Samsung-modified browser. Main issue is it doesn't offer a desktop display options! With a screen this nice and we get dumbed down to the mobile displays? Whatthe?

Don't want the useragent browser workaround either? Doesn't stick.

FORTUNATELY I found the slim uberfast boat browser or this would've been returned.

Yeah, I browse a lot...much of it for work actually.
[Galaxy S II Q&A, Help & Troubleshooting] angelomaldito:
Yes, sir! Here you are, with browser brightness at about 20% ;)

I can't see any yellow tint or any other issue with my display. I'm currently on XXKG3 stock ROM, but I have used KE1 and KE7 stock before and I haven't noticed any issue either.

[EDIT] Before I used to use stock KE1 and KE7 Kernels (2.3.3). Now I use CF-Root 4.1 XXKG3 (2.3.4) and I have to say that it rocks. (Deserved donations to CF made!)
[Galaxy S II Q&A, Help & Troubleshooting] BarryH_GEG:
The SGS2 doesn't like certain routers. Those of us with Netgear routers are getting terrific performance. Mine's better than any phone I've used. Traveling, the SGS2 isn't consistently better or worse than other phones I've used.

I haven't had any problems and I've used it with Co-Pilot in both the U.S. and Europe. It locks fairly quick and stays locked. Accuracy is as good as my G2 (Desire Z)

The screen temperature varies from device to device. Some have had a yellow tint but it doesn't appear to be the majority. There's a production/design issue that shows as a darkening on the left 1/4 of the display. The majority can't see it unless they take pics of their phones in dark rooms at 10% brightness. Screens with a yellow bias seem to exaggerate it.

Doesn't bother me.

Some games aren't optimized for the phone and cause it to run hot. Same thing for every other dual-core phone.

I use Shure 530's, a Yamaha YSP4000, and A2DP in my car and don't have a problem with the sound. If you're an audiophile stick with your SGS1 because it has a Wolfson (vs. Yamaha) DAC.

I'm running stock and get 14-18 hours of moderate-heavy use including all the syncs synching every three hours, using Wi-Fi heavilly, and using Exchange push. Load your phone up with a bunch of questionable apps and use battery monitors, task killers, and other crap and you too will have ****ty battery life.

And what phone's better? If you look at the Sensation, O2X/G2X, and Atrix forums there's a list of comparable issues. Many people that have issues have an expectation of perfection that's not realistic for a mass-produced electronic device. If you're one of them, and are seeking perfection, don't buy a dual-core phone. The vast majority on this forum are thrilled with their purchase and would recommend the phone to a friend.
[Galaxy S II Q&A, Help & Troubleshooting] angelomaldito:
Yeah, I agree. The Samsung browser definitely could offer easily a decent desktop view. Messing with user agent doesn't provide a long term fix. For this reason, I have Opera mobile on my phone, which is great for that purpose. Nevertheless, I only use Opera when I want a desktop view, 98% of the time I stick with the Samsung browser, which for mobile view is good in my opinion.
[Galaxy S II Q&A, Help & Troubleshooting] BarryH_GEG:
You realize screen shots are what's being sent to the display, not what's being shown by it...
[Galaxy S II Q&A, Help & Troubleshooting] angelomaldito:
:D yes, you're right. Anyway, if some of you guys can't trust me, I'll post some pictures latter at night in the dark. Just let me know if you wish any specific brightness, colour background, web page, etc.

By the mean time, I can only say that I've never had such issue with any ROM or kernel I had in my device.
[Galaxy S II Q&A, Help & Troubleshooting] ryandi7:
It probably is there, you just can't see it. Try loading up google with as low brightness as possible. Then cover up the center of the screen with something, look at left side and right side. That's how I convinced myself it's there.
[Galaxy S II Q&A, Help & Troubleshooting] OryZ:
Very happy SGS2 owner here... It's not perfect, but all the issues are neglibale imo, and besides there is no better phone in the market.

Would easily (and have) recommend it to a friend.

I reckon people should stop knit picking and start enjoying it, it's definitely better than anything you owned last year lol
[Galaxy S II Q&A, Help & Troubleshooting] OryZ:
Why do you need to look so hard and then convince yourself? I'm a preorder customer (which means I must have the tint issue) but never noticed it, prob because I never looked for it...
[Galaxy S II Q&A, Help & Troubleshooting] cwepruk:
My only real negative is the battery leak. Life is pretty good when the phone is being used, it's the dormancy drain that seems to be a glitch.

I've had a few different rome on another Android phone, including stock and the dormancy drain was pretty minimal (10-15% overnight). This one is at least twice that.
[Galaxy S II Q&A, Help & Troubleshooting] angelomaldito:
There is at least one sgs2 with no yellow tint on the screen(w/ pictures)

Ok guys, I hope now you'll believe me. If you say that you see any yellow tint here, please check the mirror to see if there is any, and if there is, go see a doctor. :D

I know there are many devices with screen problems, like a round marks near the top right corner, yellow stripes, and yes, yellow tint and possibly others.However, there are also many devices without any issue (probably the vast majority of them). If someone says that their device doesn't have an specific issue that yours has, it might be true and probably is. You have no reason to distrust them. :rolleyes:

If your screen has any manufacturing problem, you have the right (in most countries at least) to have either an effective repair or a replacement. In my case I was lucky, as I got my phone as soon as it became available in UK and I bought it from eBay with no warranty from a person who got it as an upgrade but decided to stick with their iphone. :cool:

I repeat that I'm currently using KG3 ROM with CF-Root 4.1 KG3 Kernel, but I have used stock KE1 and KE7 without such problem, or any other problem at all apart from the colour banding issue, which doesn't bother me at all. With a spare battery and a charger for that, I can say that I'm, indeed, very happy with my device :D

PS.: Once again, leaving Wi-Fi + Sync on all the time will drain your battery, this is a fact. If you like to leave it on all the time and even so complain about your device's battery life, instead of using a battery made in South Korea, try getting one from North Korea (with nuclear power). :D
[Galaxy S II Q&A, Help & Troubleshooting] Disfected:
All I see on your phone is blue tinting around the corners from those photos. Wonder if it's noticeable in person though lol, still waiting for my delivery.
[Galaxy S II Q&A, Help & Troubleshooting] BarryH_GEG:
Your phone's like mine - tending toward a cool/blue bias. In your pics you can see the left side's a bit darker. Screens with a warm/yellow bias make what appears as shading on yours to look yellow, especially on whites. I can only see the banding on mine when I take pics of it, not with the naked eye in every day use. I think most screens are cool/blue otherwise more people would be bothered by it. There are pics of my phone in the left side banding thread if you want to compare.
[Galaxy S II Q&A, Help & Troubleshooting] angelomaldito:
Exactly! It only appears on the picture, my naked eye cannot see it. Nonetheless, have you tried taking pictures from your TV or your computer? I bet that you'll see something similar.
[Galaxy S II Q&A, Help & Troubleshooting] ghost77:
Ignore the rainbow moire , its from my digital camera.

As far as i can see its no different then my Captivate , except for brightness.
[Galaxy S II Q&A, Help & Troubleshooting] EarlZ:
The misinformation that people are getting about this type of issue is probably the reason why Samsung will never rectify this quality control issue. Doesnt matter if only 0.00001% out of 6Million phones are affected.

I cant fully blame others as they are/either just 1.) Misinformed 2.)Visually Impaired 3.) Denial or 4.) Got lucky with the screen even on the first purchase.

I would also speculate that some batches just have better quality control than others since the majority that I have seen has the yellow tint (pre 2.3.4 kernel), out of 6 Million phones what are the chances of personally checking 30+ phones that wont have this banding?

But I guess nobody uses their phones in a dark area or never go bellow 50% brightness anyway so its a non issue for them.

Whats bothering me right now is that some shades of grey dont look remotely grey.. even the test image that was on a the website shows something more of a

Because not all screens are affected the same way, as what barry said the color temperature affects the entire visibility of this issue and yes having a cool/warm display negates a huge % of the visibility, the neutral colored screens ( best color balance IMHO ) shows the highest visibility even the visually impaired can immediately see it.

Its clearly visible on your photos left side is darker than the right side = Yellow banding, but if you cant see it in real life then thats 100% fine, what matters is what you see and not what others see in your photos. This is a big deal for some because if there IS a screen out there that shows no hint of yellow tinting or what so ever, it means that theres been a manufacturing/quality control change in Samsung and it should be about time for those who are bothered by the issue to send the phone back, take note ALL phones are affected but a difference in degree, Unless someone can totally prove it otherwise.

Not the best comparison image or scenario but as long as you dont see it, its 100% fine. I also dont see/have any yellow banding while looking at google results.
[Galaxy S II Q&A, Help & Troubleshooting] EarlZ:
This might not be a big deal for others but the biggest positive I've found with the S2 is the massive speed bump of the andriod.process.media ( on the that runs AFTER media scanning is done, responsible for pre caching some stuff), during the S1 days I had to keep the screen on for 7mins for it to finish scanning the thousands of images on my phone, with the S2 its so blazingly fast that Its not even more than 1min.
[Galaxy S II Q&A, Help & Troubleshooting] MS.:
Now i have second SGS2 (SGS2->Sensation->SGS2), so my experience of both:

The bad:

- Very annoying home button lag (i'm not talking about wakeup lag, that's different story).

- Some games crashing.

- Too addictive, can't live without it any more.

Bad but i can live with:

- Overheating while playing 3D games. Setting up proper SetCPU profiles helps a bit for me.

- Sound quality isn't THAT bad as some people says. With decent earphones and player that has an equalizer, sound quality is acceptable for me.

- WiFi reception isn't the best but still better than my previous HTC "Sensation".

- Color banding is a bit annoying too, but not too much. Depends on app i use.

- Pink spot on camera.

- Takes very long time to re-charge the battery.

The good :

- GPS is perfectly fine for me.

- Screen quality is amazing.

- Probably the best battery life i ever had on my smartphones.

- Phone is very thin and sits nicely in my hand.

- Much louder if compared to Sensation.

- Extra 11,5GB of storage (internal phone memory).

- I simply love "Smart alarm" feature!

- Can be played any 1080p video clip on the web.

- HW accelerated video playback and web browser

- 1GB of RAM.

- Blazing fast.

Overall, this is the best mobile device on market today, IMO. Yes, it's not perfect but so are it's competitors too. Would i recommend it to my friends? YES!
[Galaxy S II Q&A, Help & Troubleshooting] stoney73:
The main problem I have with the sgs2 is the people that whine, and then can't accept that they are in the minority.

They think that because they have convinced themselves that there is a life-altering problem with the phone, that anyone who says otherwise is lying or stupid.

Its quite often the same people in every whine thread aswell.

Enough already. Please take the phone back,get a refund and go buy two cans and piece of string.
[Galaxy S II Q&A, Help & Troubleshooting] Archer:
YOUR PHONE HAS A YELLOW TINT - YOU ARE WRONGGGGG!!!

:rolleyes:

My favourite thing is the fact that it's the smoothest and fastest Android phone I've had the pleasure to use. I used a lot of different Android ROMs on my HD2 and found that Nexus 1 builds were the best for me, as I really like the stock Android experience. You can keep your TouchWiz and Sense (ugh!) - I'm much happier with a launcher of MY choosing, thank you!

So yeah, basically it's fast as anything - best phone I've ever had.
[Galaxy S II Q&A, Help & Troubleshooting] EarlZ:
Because not everyone has the same low level of expectations, degree of fanboism, extent of denial and of course usage. I not pointing to you specifically.

Coming from a Samsung Wave , Galaxy S1 and several other Galaxy S2's due to exchanges and phone scouting, heres what I can say:

The BAD

- Screen "quality control" issues

* A good summary of the quality control issues can be found here

- A little bit to hard to let go of the phone despite having to go through 4 exchanges with different screen QC issues :(

- WiFi power management (24/7 usage) with IM apps running is still ages away from the iOS devices.

- A few of my favorite games dont run too well

- GPU loves to stay at 167Mhz causing slow downs in some games

- Browser has only has autofit, no reflow or the stuff that Safari adjusts to make mobile browsing better

- Quality gaming is really far behind from iOS

- Slow recharge rate unless using a modded kernel

The MINOR issues

- Wifi range is not as good as other devices not the worse either.

- Power button needs a little more elevation

- Home and back button "hit boxes" could have been made a little bigger, 20-33% bigger.

- Reduced touch screen sensitivity compared to Samsung Wave and Galaxy S1 (pre 2.2)

- Wake up lag

- Despite the powerful hardware, micro lags and jitters are present on the UI

The GREAT

- Despite having said that there are micro jitters on the UI, over all the phone is VERY fast!

- Extremely light weight

- Extremely great build quality, far superior than ANY metal based phones I've ever held.

- Putting aside the quality control issues on the screen, its great. Id have to say the best on the mobile market, not even the retina display comes remotely close!

- Plays movies w/o the need to re-encode unless it hits over 4.0GB

- Great GSM reception

- Great battery life, 9hrs of HD movie viewing or even upto 7days of standby

Misc issues that I've read from others, I probably have this on my phone but its a TOTAL non issue.

- Pink spot on camera, I see it but its a non issue get a DSLR!

- Video stuttering,frame drops, scan/wave lines, non-issue its a mobile phone not a RED videocamera.

- Bad battery life, your phone / battery is probably defective.. I've been with several Galaxy S2's and not a single one had bad battery life. Have your battery/phone replaced.

- AOS bug, mostly caused by rogue apps or user error. Non issue, very minor.

- Home button lag, just something to white about :p

- Overheating, again this issue at the extreme minority, get your phone replaced.

This should be it for now, Ill repost whatever merits I can find.
[Galaxy S II Q&A, Help & Troubleshooting] holyguyz:
After struggled for plenty replacement due to various problems on my SGS2, now it's better on my 5th replacement unit.

My Rating (Worst :mad::(:);):D Best)

:D 4.3" SAmoled screen - Gorgeous!

;) Sound - Not bad at all. Just tweak around for better sound.

:D Design - Outlook absolutely slim, light and pro.

:( WiFi - very bad (mostly weak)

:) GPS - ok (sometimes take too long for detecting satelite)

:mad: Pink Spot Camera - hopeless (official issue, nothing to say)

;) Overall - Satisfy with my current SGS2. Performance pretty smooth and faster as well. Nothing can stop me now.

HI first of all. I'm noob at this forum so it's ok to hate me :)

So.. i have sgs2 for a week and i'm piss-off at some point from a high end phone like SGS2.

I have all above issue except GPS, witch working well.

So what should i do? My Wi Fi is weak as $hit. and yes annoying yellow stuff on the left side of the phone when is on low brightness.

DO I RETURN MY PHONE because it's under warranty on contract with t-mobile or there gonna be update that will fix yellownes thing and wifi.

Comming from a HTC Desire, I must say that the SGS2 is the best buy I have ever done.

Everything is faster. The screen is the best I have ever seen on a mobile phone.

The battery last as you would suspect. More then long enough to suit my needs.

I can charge everyday if needed.

So far I have nothing negative to say about it.

Btw, I am running XXKI3 and CW-root. Almost the first thing I did when I bought the phone.
