The back LED of the camera can be used as a torch, but it does not seem to be quite bright. Is there any method (probably with root) to amplify the lightstrength known yet?
Have you tried the Nexus or CyanogenMod Torch ?

No, I haven't tried any of them because I don't own the Z2 yet. The Torch-Function is quite important for me and I would hesitate buying it If there was no solution. I would be very pleased If any owner could try them and report about the results!

There is a torch app for Z2 somewhere in xda. However note that Z2's LED is rather weak when compared to others. I can say that it's only half as bright as the Samsung S2

Why don't you just pick up a Fenix LD 01 and stick it on your key chain ?
if i had to walk on a dark road there is no way a mobile would suffice.
This thread is not about persuading me of the uselessness of a smartphone torch, it's about possibilities to avoid sony's restrictions which darken the foto-led when used as a torch. When taking fotos, its much brighter, so it's rather a soft- than a hardware problem!
See, its the underlined bit that i don't get...

Of all the reasons to come up with not to buy a Z2. Seriously is that it. Why ?
If i was looking for a torch and it was 'important' then i'd look for something fit for purpose as in a 'real' torch.
Good luck
Sony's LEDs are quite a bit weaker than those used by other manufacturers. I have never seen any software that even promised to amplify a phone's LED flash, and probably for good reason - the LED may survive repeated short high-intensity bursts but may burn out quickly if used at maximum intensity for an uninterrupted minute.
If the performance of a phone's LED torch is, for whatever reason, one of your priorities, you might be happier with a Samsung. Their LEDs are much more powerful.

Hello! This is a request to all the developers for Galaxy S II. You probably already know that some Galaxy S II suffer from the problem of low-fps (stuttering) with low-light conditions. That is resolved with the firmware of the camera of the Samsung I997 (Infuse 4G), but putting this firmware, the LED flash does not work anymore. You can change the firmware?
The firmware does help is the SIEG03. Camera firmwares topic here on XDA: http://forum.xda-developers.com/showthread.php?t=1098834&page=110
Thank you in advance if can help.

It would be great if some of devs look at this fw and changes what is problem so flash stop working
Indeed, i would be great +1
I sent a private message to Chainfire and email to Supercurio. I hope they meet!
Great thread! SC cameras are the ones that have low light framerate issue. If someone resolves the flash issue it will be great.
Is this the same thing as the low-light autofocus laggy thing?
I made a video at my friends birthday in a nightclub and it's crap! Had to delete it! Blurring and lagging every few seconds!
I know potatoman might do something about it but he's busy at uni now, I'm kinda surprised nobody has jumped on this issue. One of the big reasons I got the S2 was the camera...turns out it's not that good
Yes. Its that problem. And is laggy beacuse of some galaxy s2 camera modules have some bad firmware. The SIEGO3 fix the suttering in video but remove the led flash of the videos and we cant use it like assisted lamp for autofocus. If someone implement in the firmware, our problem is solved.
+1
It would be great! Thanks
Maybe someone who knows cyanogen can tell him to tell samsung to fix it. I mean he does work for them now

Maybe Samsung are aware of the framerate issue... they should be considering how many of us have this problem, but before they can release the firmware it proberly need to be tested ect so takes time.
Im using the infuse 4G firmware & more than happy to plod along with it, until a fix is released by either a Dev or Samsung.
I had a Galaxy S before i got the S2, so having no light in video isn't to much of a problem for me, the camera flash works which is more important, even without the pre focus light the camera still locks on 99% of the time in low light.
TBH that pre focus light of the orginal cam firmware was annoying as hell to some people, as it use to blind them before the flash kicked in lol.
Anyways im happy with having constant 30fps in either 720p or 1080p without any framerate problems.
The well-known dev's are unlikely to respond to PMs as they'd get hundreds\thousands a day, mostly from noobs, so unless they're from people they already know, I wouldn't expect a response. Plus a lot of them don't frequent XDA as it's turned into a noobfest where the "popular" devices are involved.
You could try posting over on the Cyanogen forums.
Steve (Cyanogen) is not likely to be in a position to "tell" Samsung to fix anything, and certainly not for a device that is as old as the SGS2 is now.
You could try logging a fault with Samsung themselves, they have been known to respond, but I wouldn't hold your breath.

The same for me! I don't feel a strong lack of flash, but can be useful with app. that use it like "Tiny Flashlight" etc.

Just a heads up that while I'd love to help with this, I don't experience the issue myself, so I wouldn't even be able to test if my fix would work or not. I'm also not comfortable with my code being flashed- my firmware modding capabilities are limited at best... and flashing a bad camera firmware can be irreversible.
Sorry guys, good luck finding someone else who can help though.
My SGS1 took a dip in the water etc. I saw the nexus keynote, ice cream and so on, compared specs, prices, and i have an opportunity to buy this thing cheaper from a supplier. However, i was greatly dissappointed from SGS1.. specifically the lag, and the gps problems.
I read awesome reviews about this thing, and they all agree on its greatness.
Thus im asking, is there any specific issue, problem and so on, like lag, like battery drain specific to this phone, gps etc whatever, a reason NOT to buy this?
Im looking for people who have had the phone for a while.
Thanks
Um think you got the wrong section.
You're talking about the nexus, but you do mean the SGS2 right?
no i meant that i am aware of the nexus prime and all that is going on. but im not in the wrong section, im talking about the SGS2 BEAST
No reason at all not to buy the SGSII remains the best there is 100%, if you get a chance of a good deal id snap it up.
this is so weird, there were quite a lot of people dissappointed with the first one! so happy to hear that.
Are official firmware updates good enough? has it been improved since release for example?
I've had my S2 for about 3 weeks now and I'm yet to come across anything that's made me look twice about choosing it.
If I had to be really picky then I'd recommend you buy a 3rd party USB cable as the one that's shipped constantly loops "connected/ "disconnected", be careful when removing the battery cover - it really is as flimsy as some of the reviews say however when it's in place it feels solid and finally the app drawer doesn't automatically sort into alphabetical order so you either have to do so manually or sort everything into folders (even then it doesn't have an option to sort by anything other than date).
On a side note I have read a lot about people having problems with Samsung Kies Air but haven't used it so I can't comment.
Apart from that it's a cracking piece of kit in my opinion.

it's entirely up to you what you do with your phone but i recommend rooting and flashing a custom ROM, CheckRom is currently merging with Leomar's Revolution ROM to make a super ROM so i cant wait for this and obviously ICS will be coming to the SGSII soon too so that is going to be fantastic,if i were you i would read up extensively on here, i done this 3 weeks before i even got my SGSII so i was familar with some things, freeze all Samsung bloatware and you'll have great battery life, clear cache every day too speeds things up,i recommend Siyah kernel too probably the best there is and the one responsible for getting rid of the dreaded Android OS.
As i said read,read,read the many stickys and topics and in no time your phone will be absolutely top notch.
The only downside I've found so far in this phone is that it can get extremely hot (around the upper side, the camera, where the CPU is, I guess), reaching a temperature that you can't even touch it (it's hot only on the upper area, that means you can still hold it, but not touch the upper area). It only happens to me when I use the browser for over a minute, or when I use the phone in general when it's charging.
Other than that, everything in this freaking phone is amazing!! The screen, the camera... everything! When the new android version comes, the phone will get even faster because of the multicore support, can't wait for it (although it's fast as is...).

i disagree, the camera is only 5MP and IMO the screen on the nexus is just too big, asides from that it looks good but ill stick with the SGSII until the SGS3 is released next year.
Only falls short on pixel density imo, particularly noticeable when browsing on desktop mode, have to zoom in a bit to read.
Minor but still a minus compared to SGNx.

I saw that before but dismissed it as aftermarket (check additional logo).
however, that said I've popped the cover off plenty of times and it isn't anywhere near creaking. also unlike some other phones the back is replaceable if it does break.

Just to prove a point that Samsung know what they were doing!
I have done the same thing to my battery cover and I can confirm that it is not flimsy at all.
The light weight of the Galaxy S2 is of benefit to itself when accidentally dropped.
It's less likely to break !
I'm not sure if you folks have seen this video yet was posted on here the other day and says it all really.
I seem to remember when I first owned the device some members were saying that the camera works well in the early builds...been waiting for forever for new updates to fix the camera and yet it still suck...anyone has links to those builds? I did a search a while ago and was unable to find any archives for the C6833...can someone give me a direction for me to start searching? Many thanks. And, I actually prefer the older builds where the screen's lighting would not change due to the color of my content
You remember wrong. The camera wasn't better on earlier builds. You had the option to disable adaptive backlight, but it would cause SODs (Sleep of Death), and a lot of other bugs, so it's not even worth it. Sell your Ultra and buy a phone with a better camera if a good camera is a priority.

Hey guys.
So I love my pocophone and the latest beta update (i'm actually using Xiaomi.eu Rom) does seem to improve a lot with the phones touch lag issue; however, I still kept getting some stutters during scrolling and in particular vertical scrolling. I believe this might be due to screen response times mismatching with screen refresh rates. I believe so because if I dragged my finger at relatively slow speeds (approx 7.5 s to go the entire vertical length of the screen) across even a relatively small page (my app drawer for example), the page would jump as if it didn't track my finger for a split second.
So things I did without much success:
1. used other kernels: franco and extreme (extreme kernel with 65 Hz screen refresh rate was a bit better though)
2. changed animation speeds. (also turned off animations)
3. turned off mi optimizations etc.
Today I found this old forum post on xda (https://forum.xda-developers.com/android/software-hacking/mod-increase-frames-5-14-15-t3108786). The author changes the egl swap interval to allow better screen refresh and fluidity. I am not an actual developer so from what I read, it seemed like it might be a decent thing to try. I didn't flash anything however I used the terminal command "setprop debug.egl.swapinterval -60" as suggested by author. This won't stick past a reboot but I think it did help with scrolling smoothness and fluidity.
I was hoping you guys could try it and let me know if there are any differences for you guys.
PS: Again, I'm just tinkering and trying to see what happens. Hoping to get some input from others just in case what I see is placebo. Didn't have any negative effects and I hope you don't either.
I really want to buy this phone but if the "stable" update does not correct all the touch issues (which i strongly believe it is a software issue), i won't buy it.
Of course you have that right. But a few things. Firstly, the phone is great, please use it for a bit to experience this. Secondly, I am being knitpicky and actually most people are reporting no issues whatsoever. In fact, this post is about the fact that I am not currently seeing the stutters. I am wondering if it's because of the changes outlined above and was hoping we could figure out together. Might even be that something else I changed corrected the issue. I just didn't realize it then. Lastly, if you're looking for the perfect phone without any issues, you might have to look away from "flagship killer" type phones. These phones typically give performance that comes at the cost of tiny issues. So are you a fan of the best bang for your buck, the highest highs of performance at the cost of minor tradeoffs that you can work with an active community to fix. Or do you want a perfectly smooth experience. At this price point, you don't really get both.
If the command has helped you you can set the command to run on startup. And try to use a stable build.

The touch issue is not software issue. It has been partially corrected through software, but it will never be fixed. If you want to buy a poco, be sure to search one from December batch because it has the Focaltech panel which is ok, and not the Novatek panel which is the ****ty one.

They'll ignore you like nothing. Eventually, you might get the standardized reply on their support center, and in the end, you'll realize that nothing they told you will "Fix" the issue because the issue is not device specific here, it's their horrible post-processing which impacts EVERY S23 series device.
Want to get rid of their trash post-processing? Start using Gcam.

This is agressive even for a dslr, don't expect more from a cell phone .
It's not a secret, that most if not all cellphone supplier rely mainly on post processing, and from I saw on your picture this is normal.
Nowadays, is less dominant, but I do remember when we had older sensor on S2 , S3 and so on, those artifact were there soon as the light was a little bit low.
