So we have to do real scientific research on this issue. Reminds me of the same discussion we had when HD2 came out. Mine (like SGS2 prordered at expansys) worked flawless from the beginning (except the heat issue in summer).

Now my SGS2 runs for 1 full week with no single freeze, not rooted, no unusual batt drain (1% per hour in idle both with 3G/HSDPA and Wifi), 100+ apps installed, some 5star rated system tools, simply the best phone I ever had, capable of more than my expensive Vaio TT 92.

We have to collect infos on:

Which country

Which language

Branded or unbranded

Carrier

OS version

Settings !!!

It can't be that a few have so much troubles and (I believe) the majority not. There must be something else behind it ......

With HD2 it turned out that a lot of probs were caused by Vodafone, T-Mobile etc.

When SGS2 drains batt by constantly trying to sleep and waking up it is not necessarily SGS2 or Android, maybe the cause is external

Wifi - mine seems OK - although my router does have dual antennae so maybe that is why?

Screen - Never noticed a blue tint. Only thing I've noticed is the "16-bit" colour effect, but even that isn't enough to bother me; compared to an iphone 4 the screen is not as sharp with small text in the web browser, but more than makes up for it with its vibrancy and huge size... after looking again at an iphone 4 the other day, the screen frankly seemed PATHETICALLY small.

GPS - Maybe not quite as good as the iphone 4, but that is subjective at best, but it is no worse than my Incredible S (directly compared on the same route); the SGS1 I had was frankly as much use as a chocolate fire guard.

Random Reboots - Never had that yet... unlike the SGS1.

Poor sound output - So far, the biggest disappointment with this phone for me, it sounds very weak next to the iphone 4. About the same as the Incredible S. That is NOT a compliment. Not loud enough, and lacks punch, and really doesn't sound very good. Good job I've got a Sony MP3 player.

Other issues - battery - I had a couple of occasions where I suffered SERIOUS drain, but since flashed KE1 its not been too bad, but the problem is definitely not 100% solved, with high Android OS usage and occasional high Wifi Sharing usage (but I do occassionally use Kies Air which is an excellent app IMO). I'll be charging this every day and the battery life is about equivalent of the Incredible S but not as good as the iphone 4.

Overall, pretty pleased so far... and the original SGS pissed me off so much.

this phone was released 2 weeks ago and in a majority of countries, this phone is not even released. So keep cool, the problems you have listed seem to be software issues and can be fixed by firmware updates. Either by roms or by samsung... samsung already showed their effort by fixing the auto-brightness issue last week.

However, I never had a single reboot, don't have any GPS issues, tested it more than one hour today (without a-gps!!!). But I have to admit that wifi range is not the best, but lets see how samsung gonna fix this.
[Galaxy S II General] mikeDCMDVA:
Is this phone 4G capable? Is it going to be when it arrives in the US?
[Galaxy S II General] JJEgan:
Troed .

some 5star rated system tools care to name those tools for us .

MY phone is O2 UK with KE2 firmware XEU CSC rooted with Chainfire and reflashed KE2 kernel .

GPS Excellent

Battery life

dont really know how good it is as its been flashed a number of times and needs time now to settle down .

WiFi at least the same as SGS 1

Sound via headphones on 50% sound level and tested against standalone MP3 player same music no complaints .

Think we need a separate post topic if we are to carry your scientific tests through .

it supports 21Mbps download. call that whatever you want, 3g or 4g, but that's the speed it supports.
[Galaxy S II General] bilboa1:
wifi on my sgs2 is the same as on the sgs1. i live in an apartment, i can go outside and still get a weak signal, then it cuts if i start walking away. my laptop goes a bit further, but not so much. i'd say its average wifi. <5m range is obviously an issue or the wifi bandwidth being saturated. When its saturated if other devices emit stronger than the sgs, then your signal will be crap. Not sure what power the sgs outputs, on the sgs1 the driver power report is all broken

the blue is normal (amoled blue diminush faster over time than the other colors so it's stronger from factory) but if you don't like it you can change the color profile.. (/etc/mdnie_... or use the presets)

the sound is not worse, its different. I don't especially like it either but it's not horrible. less warm. Sharper and more high pitches.

You can fix with the 9 (!!) band equalizer from the samsung player, but not eradicate it. Even with bass to max its still a bit weak. I'm being picky tho.

The GPS.. I don't know what problem people have with it. Works much better than most phones i've ever used.
[Galaxy S II General] RADLOUNI:
Could it be HARDWARE Quality

Hi Guys

its amazing the fact that a fairly considerable number of people are reporting problems, and then equally considerable number negating those problems.

I dont believe anyone is lying, and most people here are techy enough not to be doing something seriously wrong to cause those problems.

IMHO, i believe that it might have to do with different Samsung manufacturing facilities leading to different manufacturing quality, or even ICs (chipsets) not tested enough before being used to produce the phone leading to some handsets with a lower quality than others because of a randomly low quality IC. Samsung is under a lot of pressure to produce large numbers of SGS II to meet demand, and this leads to such kinds of problems

Maybe that is the reason the quality of the mobile is fluctuating from person to the other.

were i come from, the problems encountered by most people are not enough to convince the dealer to replace the phone as you cannot provide him with a solid proof that GPS IS NOT ACCURATE, or WIFI RECEPTION IS POOR, or screen is a bit BLUISH. They replace the phone only if it is not working at all or if there is something extremely obvious:-)

So i am gonna sit-out this phone and wait for phones that provide a more stable overall build quality

Dont flame at me guys, just giving an opinion, you can stick to your SGS II, it is a great phone
[Galaxy S II General] JJEgan:
Its always user choice but do the same checks on your next phone is what i say .

cancelling you order

By all means cancel you orders people if you are worried about getting this phone, however be sure to read up on all the other phones available as you will find people moaning about their phone and every aspect of it on every forum. The only time you wont really see this is where the phone has matured and people have got used to its idiosyncrasies and stopped bothering to chelp about what are essentially minor issues and just start enjoying it - who wants a phone thats 12 months old though???

Granted this might take a little longer for some handsets, the HD2 took a real bashing before things settled down but it turned out to be one of the best handsets made to date and with the help of XDA dev is still rocking.

I think we will find that when ROM dev gets moving this will wipe the floor with anything out there.

Give it time people, its barely out of the womb.
[Galaxy S II General] bilboa1:
i don't believe much in hardware differences

it's usually usage differences or simply pure crazyness eg when you expect something not to work very much, you might think it doesnt work very well, while it works just as average as the other devices

^^

for the wifi, i noticed if you have the phone in your left hand you can actually decrease the wifi signal by a lot (yeah, grip of death for wifi, etc lol)

aka covering complete left side and lower right side at the same time

in the right hand, np

(noticed that by playing around 10min ago :P)

still at 5-10m ive 30signal with that grip, but if your wifi access point isn't as good as mine, and maybe your area is full of other wifi users, it can be bad
[Galaxy S II General] JJEgan:
Same bottom half of screen drops Wifi. one bar

jje
[Galaxy S II General] RADLOUNI:
partially disagree

I agree that all phones have some problems OUT OF THE WOMB, but in all honesty i find that other vendors have less serious problems OUT OF THE WOMB.

Samsung software/hardware developers have made good strides since the SGS I, and this shows in SGS II, but i have to say that they still need more experience to catch up with the maturity of other vendors

dont forget that their first attempt on a high end mobile phone was only one year ago

please dont be so dramatic in saying that it will wipe the floor with other phones. No phone is going to do that, every phone will have its cons and pros

At the end of the day its a matter of personal preference, i.e. what problems you think are deal breakers, and what are not
[Galaxy S II General] intruda119:
The HTC desire, DHD, HD2(best of all), HD7(pathetic) had horrible audio. headphones or not it was the worst compared to my vibrant. I work with animals(mostly dogs barking) 10-12hrs a day and listen with the included headphones while at work. The sound is great compared to the recent hd2 and desire hd i just recently owned. Might want to check the quality of music your using/downloading. I also plug the sgs2/fiances iphone 4 to my car and output is great coming thru my subs/amp. Hear me coming from a block away.

Wifi is excellent in my house. Im getting 2 bars where my vibrant, atrix and hd2 got 0-1.

GPS has locked on quickly with no issues. Driving from Tallahassee fl, to Atlanta, Jacksonville, Orlando, Tampa, Alabama with no issues on directions.

Screen issues are non existent on my handset.

Im coming to the conclusion that some of these problems are user error.
[Galaxy S II General] mistxx:
Had my sgs2 for 2 weeks now and not a single issue.. Updated using Odin to the latest firmware KE2.. Working fine.. Dowloading torrent files.. Recording 1080p movies the works.. Wifi is no different to my original sgs.. No reboots period.. Gps works fast.. Phone is rooted using Chainfires excellent fix.. And back on KE2 KERNAL since rooting..

Cannot fault the phone and Gingerbread.. Even got gtalk video calling going altho the person can't see me but I see them.. Probably config issue.

Anyway works well for me.. Best phone out there.. Now to see my original sgs!
[Galaxy S II General] intruda119:
+1, hopefully the sensation is the perfect phone for the poeple with problems.
[Galaxy S II General] Jabbypants:
Best phone i owned my Iphone 4 sits un-used now, can't say I get wifi issues works fine, not had one re boot/lockup at all. The 1080p recording is the best out there, no need to say any more leaves the competition for dead.

The Optimus X2 is one of my worst buys so far if some of the doubters think this phone isn't there cup of tea don't get that phone mine went on the bay with in a few weeks of owning it, crap video recording, no focus on video recording which is poor, just a bad phone imo.
[Galaxy S II General] mcreego:
Thank You for your answer Bilboa. A very good one! I hope that developers like You could inproove our beast.

good night
[Galaxy S II General] jimsey:
If your having issues, upgrade to latest firmware and be patient, the hardware has lots of potential, and android is improving all the time.

My gps is great if not a little power hungry,

my reboots were solved by a full wipe and reflash,

Wifi depends on how you hold it ( try not to cup it in both hands - lol)

As with all smartphones, the battery gets better after a few weeks of use.

I've no complaints really, its brighter and faster than my old nexus s

Sent from my GT-I9100
[Galaxy S II General] Uncledeewz:
I'm very sad hearing all the problems people are having. Got sgs 2 last saturday and I havent had any issues. The first thing I checked for when I got the phone was the issues people were reporting and except for a little bit weak wifi signal the phone has been perfect in any way. Best phone I've had tbh. But as someone else said there are many conflicting reports about these issues so maybe there are some faulty devices out there because of huge demand... Anyways hope the issues get fixed so we can all enjoy this amazing phone:)
[Galaxy S II General] Raymond77:
Rubbish.

I am two floors away from the router and have no problem with the wifi lock or throughput. Less bars than my pc? Yes, but the conenction is strong and I'm able to get a good 10mbps without a problem.

I have not noticed any blue tinge to my screen.

I took my SGS2 on a 20 mile bike ride with My Tracks and it kept a pretty good lock on the entire journey, never off by more than a few metres from what I can tell by looking at the route on Google Maps. And that was with it in my rucksack.

Random reboots are really common eh? I've not had a single one, and I've had mine since launch day, on and with me 24/7.

My only gripe is battery life, but that has improved markedly over the past few weeks, and I'm now happy as Larry...
[Galaxy S II General] poloboogie:
just got mine and im in aww, best phone ive owed so far camera is my favorite feature so far, but i really do hate the lockscreen hell i would have preferred the puzzle peice over that crap every other point he pointed out works great for me. can some one please point me in the right direction on rooting, and all the goodies
[Galaxy S II General] stoolzo:
its already wiping the floor and pissing in the Kettle of all other phones and the IPAD 2 with video performance, I stand by that claim.
[Galaxy S II General] uskr:
I have my SGS2 for two weeks now.

My past phones:

- iPhone 4

- Captivate

- Nexus S

- Inspire -4g (the minus signal is to donate how much it sucks)

- Atrix

That been said, I had/have none of the issues the original poster posted. The Wifi is a little on the weak side, but nothing bad. Never lost connection while using it.

This is by far the best phone I've owned so far. Once you have it, all other current phones seams like a 1year+ old phone. Samsung did a HUGE leap in hardware and software quality.
[Galaxy S II General] awesome-member:
you may have a faulty one.but for your problem regarding tint. try changing the screen to movie mode. it is slightly warmer so there are not blue tints. if you don't know where it is it is under setting > dispaly > background .....

if you could mention what headphones or earphones you are using.
[Galaxy S II General] jonrwg:
Just wondering where did he (thread starter) went?
[Galaxy S II General] shabs52:
Uh what do you mean "whoever is saying wifi is fine is lying?" I did speed tests and my d/l is about 15mbps. not as fast as it should be but definitely not weak either. i don't notice the blue tint or maybe am just not looking hard enough. this phone has restarted 4 times... but thats cause it was me that restarted it. and once after firmware update. so no... no random reboots. im using shure earphones... sounds amazing, can hear every single thing ... even from streaming tv shows (which isn't HQ but still sounds great). so no... not everyone is having these problems.
[Galaxy S II General] leedavis:
What random reboots? Not rebooted once in 2 weeks. I have no issues with this phone, just Android which still needs a lot of work.
[Galaxy S II General] Intratech:
I've had mine since launch day at P4U, I famously had to chat up the store manager to get her to sell the one device they got sim free. I too have a perfect device and I do agree it's the best phone I've owned.

Mine rebooted everytime I updated the firmware and rooted it. :mad::mad:
[Galaxy S II General] Datavampire:
Had mine roughly a month(i think)

Wifi : as has been stated although it may not have full wifi bars, its locked on i have never lost a signal and downloading/uploading is fine.

Batt life. i have had a few other phones, dhd was my last and the batery life is outstanding, i think i have what is moderate use per day, odd gaming, lots of txting, facebook/emails odd calls, and mine lasts near enough 2 days (although by then its nearly flat) i do not see a prob with batt life, most people are iether at hoime or work it is very quick to recharge the phone, what is the isue realy, that you dont liek carying around a charger ?

Screen - im no expert, i coudlnt realy tell tbh

Reboots : I can honestly say the only time my phone has rebooted is when i have told it to(alas no reboot shutdown, switch to turn back on) is a reboot option im missing ?

Gps : i havent realy used it tbh to make a judgement.

Sound : now here i do notice a difference, as people who have owned a dhd will tell you the sound on this phone is far superior, you need to compare sound for sound, not from diff sources, ie amps conected to pcs(wich is a silly comparision, becuase then you have to take into account, sound card, then the technologies of the soundcard, amps speakers and ofc wires conecting them, ect ect)

Overal i am defo happy with my nice lightwieght thin smartphone, and cannot wait for development to cmmence.

the above is jsut my £2 worth

In all honesty guys you buy into new technology then wine and complain that its not perfect it does make me laugh, i suspect you have got a fualty phone. the small niggles will be fixed over time, if you want to avoid all these, sell the phone dont bother getting one until its been out a while, so they are fixed via here or samsung ect.
[Galaxy S II General] CandyAndy:
My 2 cents:

I have no complaints about wifi reception. It is almost always 5 or 4 bars. Maybe once I saw it drop down to 2 bars when I want to farthest corner in the building. I can actually still get 1 bar and use my wifi when I am outside in the street of my building.

With GPS no problem. Same as with Desire. Locks fast and is accurate.

For my eyes the screen is gorgeous. Also other people seeing the phone have been amazed. Even those who aren't so "hi tech/nerdy" like my girlfriend.

Random reboots. Ok, I did have this once already. Lets see if it happens more often.

Poor sound output. If you mean with the headset which came with the package I can't say about that because I threw them away the moment I opened the package.

With the speaker it is actually pretty ok. The only complaint is that there is just one speaker and if you block it with a finger it gets completely muffled. The location of the speaker is also strange. Usually you block the speaker when you hold the phone normally.

I have been wondering if this is some Samsung design so that when you are holding the phone the ringing doesn't have to be so loud because you can see if somebody is calling you. So you already have "a clever" way to lower to sound..

And then my issues.

Battery life..oh my dear lord..Took this out of the wall 1,5 hours ago and already down to 77%. I will cry myself to sleep but this is something which can't be. Maybe have to return the phone and get Sensation.

[Galaxy S II General] JJEgan:
Simples majority do not have a problem and never post in any forum .

Minority have a problem and a percentage of those let everyone know and disbelieve anyone that says otherwise and thats for many items not just SGS .

Dont doubt some users are having random reboots > i would ask why Samsung or an app or even a bad update .

Likewise as with GPS some are reporting it as poor but 14 million users did not >> Again why user error ??

If i had either problem i would try and work through various fixes before returning the phone . I would not spend the next two years winging online .

jje
[Galaxy S II General] CandyAndy:
Ok so I just tested the GPS, this is a deal breaker for me but it wasn't accurate at all. Was constantly off road and never got blue circly away. So it was always showing only 40m accuracy. Sucks big time. This might be a reason to return this device and wait for Sensation, at least HTC knows how to make a good GPS in the phone.

And even thou their battery dies after a day of use, I have been using S2 now for 4hours and only 45% left. So it will day before I get back home from work.
[Galaxy S II General] mcreego:
Ok I didn't want to say this phone is bad, but it has several issues that I hope will be fixed by developers in the next months:)

I just wanted to say that this phone has a lot of potentials but if You want to make it work good maybe You'll have to wait for developers because Samnsung didn't optimized it very good in my point of view.

Every terminal has problems, but as I can see, this device shows almost the same little problems that my first Sgs had.

My earphone is this: QuietComfort® 3 Acoustic Noise Cancelling® from Boose sound
[Galaxy S II General] jonrwg:
Wow, what you did for 4 hours? :eek:

This never happen to me even I whatsapp for 4 hours. hmm..
[Galaxy S II General] ph00ny:
Pretty much sums up my experience. GPS, signal, etc are all better than my captivate

Regarding wifi issues, i posted in the other wifi thread but i get slightly better reception than my captivate at 2.4ghz band and regardless of the number of bars, i was not able to get below my cable connection capability for internet. speedtest results were posted in that thread
[Galaxy S II General] gidyeo:
wifi :

i'm living in the loft (2 floors above ground) of a detached house with router (802.11g) on the ground floor, yet still getting one bar on wifi. Had virtually 0 bar initially but after tweaking with the channel setting one bar is the best i managed. Good lady's blackberry is getting the same if not marginally better signal so no real complaint here.

Reboot:

None so far and long may it continue :)

Screen:

Not doing photo-editing on the phone so not expecting IPS panel performance here :D love the AMOLED display though.

The only issue that i've got is with the overheat issue mention in another thread...
[Galaxy S II General] stoolzo:
what signal strength are you getting with wifi analyser?, what tweaks to your router are you referring to, did you just change the channel to something quieter?
