will the Galaxy S2 camera app need to be hacked again? - Galaxy S II Q&A, Help & Troubleshooting

for those who have the phone, does the camera work when you need it to, or does it shut down at 15%? additionally, can it be used while playing music, or does it stop your music?
if not, i hope the hacked camera app we saw on the S1 will reappear on the S2.. i would be very happy to donate to anyone willing to work on that..

I hope we don't have the problem, 15% is still perfectly usable. Maybe like 5% would make more sense, but on a phone like the SGS2, 15% is too high.
(Btw noticed you live in Cleveland. I'm from there haha, but I live in Florida now)

{Q} People who have updated...are you reaping the benefits?

I have the webtop hack on mine so I don't have the update yet, and with no root ability yet I'm not having it. So I'm asking is there a considerable plus to having the update done? I don't have a car dock so don't care about that, battery life will never be improved, I can push the power button myself when charging, and the finger print thing....well that does drive me a little crazy. So should I take off the hack for the update and wait for root.... or just wait, because its not that great?
yep, first thing is battery is lasting long..28 hours moderate use, still 30%
fingerprint scanner works great..
free memory increased by 200 megs..
but you will lose root...
I haven't noticed any difference whatsoever.
Battery life is the same for me and the fingerprint sensor is about the same.
Free memory? You mean storage space? Definitely not RAM.
I don't know if overall stability has really improved or not. 5 minutes ago my browser crashed for no apparent reason.
After 1 day it seems like this update is a letdown. Perhaps dock users are benefitting from it. The sooner they fully release this thing the sooner they get working on an update thats actually worth a damn.
Yesterday I used mine off charger for about 12 hours and was still at 60% battery. I was shocked, but not worth the trade off for root. I'm waiting for Motorola to send me a survey on it so I can give them a piece of my mind about locking the phone down even more. I sell these things, and customers that are interested in the Atrix are only interested in it's specs for mostly a hacking standpoint. People who want simplicity get the iPhone, that's all there is to it. Blocking Psnuter is rather lame in my book. I'll be flashing back to stock then back to gingerblur tonight. The update also killed my lock screen, but I think that's because I used Titanium Backup to restore my data. Now I only have pattern unlock, and I can use any pattern to unlock. I can also just press any of the circles and it unlocks. Kindof a neat trick, but not worth root loss.

I meant RAM, i see now 200megs free..before it used to be 250 meg free, now its 450 free
Well, I guess I'm sitting tight and not restoring for the update then.
the update is good (fingerprint better, battery life better, wifi on simunlocked device still doesnt work tho), but loosing root isnt acceptable for me at all, so i restored back to the retail sbf.

Hold up, you mean if the device is sim unlocked you can't use wifi ?
I am not sold on the update
I updated and lost root and the webtop mod. (I knew this going in)
Battery is about the same.
Fingerprint sensor is maybe a little bit better.
Touch screens and input seems quicker.
But I have had some issues:
-Wifi takes longer to lock
-On Pandora sometimes I want the screen on when I am in the car and the screen shuts down anyway.
-For the first time Endomondo had problems getting a satellite lock after the update
And the nag screen about the update bugged me as did the Motorola questionaire about rooting and mods..
I am going to wait and see if the gurus get root. If not it is back to retail sbf and restore apps and data from Titanium...

dude, just read this thread:
http://forum.xda-developers.com/showthread.php?t=980047
I also received the update. To me it seems the fingerprint swipe is more reliable. The battery life is greatly improved.
I do have some issues with wifi disconnecting and reconnecting - but I think that is my router that is recycling, because my wife's iphone has the same issues, and at the same time.
welk I am happy the touchscreen works great now. Battery life I don't know I game while streaming radio. But touch screen is only thing I really cared about. More than root. Untill we can get Overclock I don't need root that badly. Cache mate, setcpu, TiBu, root explorer, and a couple more. All those for a working touch screen and a little faster unlock (slide)... don't use the finger scanner, but when I did factory out of the box it worked everytime the first time. Maybe.... "your not holding it the right way" Lolololol.
Geez, I might as well have just put a poll, because it sounds like its hit or miss down the line. I'm still staying rooted though. At least until the hsupa update comes.
updated yday and flashed back few min ago, for me there was no change at all. love webtop hack to much

low gps signal?

ive noticed i my gps signal constantly drops out while navigating and the only way to get it back, is to hold it in the dash with absolutly nothing blocking it overhead. With my OG evo, i did not have any issues whatsoever, always a strong signal. does anyone else have this problem? im considering replacing it, unless its just a software issue that may be fixed in the next firmware update.
Same issue here.

Everyone's issue?
I want to love this phone but it seems im going to return it soon one i get it and get the optimus3d.
I do not want problems with any hardware or antenna.
I have some ideas. In /system/etc/gps.conf there are some lines that look like if changed would help. I changed the intermediate accuracy level to 100, and where it said disable.agps.in.wimax I changed that to false. It may also benefit to change the allowance if intermediate position to zero. And old hack we used to use was to add the line QOS_ACCURACY=16, but I think that's the same value hack as the one I just mentioned. Feel free to try these. I don't use gps much, so my modifications may go unnoticed. Ymmv

Waaahhh. How in the living hell do you know that an UNRELEASED device has "no GPS issues" - for real. Also, have fun with the awesome monthly premium you'll get for AT&T and their awesome network If you can develop a little patience, I would tell you HTC has awesome build quality, and the dev support for this phone is great, so GPS will get better. Maybe not by tuesday, but sometime.

I live in the netherlands where its already released and im getting it tuesday. Your posts doesnt make sense.
You cant improve hardware with software...you can tweak to make it work a bit better...but it doesmt chance the hardware...
well the thing is, i believe the gps hardware is just fine. its probably the same chip they use in other phones. hopefully were just a few tweaks away.
Same exact issue.

do you use your Google navigation often? If its an issue thats not widespread, then ill probably just take my phone. I just dont feel like going through the hassle of getting a new phone if the refurb is going to have the same exact issues.
I have the same issue. Constantly losing GPS when I didn't have this issue before in my area on an Epic 4G. Sprint TeleNAV and Google NAV do it.
I’m an extremely heavy GPS user. I used my Evo as my GPS every day for work, and now my Evo 3D. In the year that I had the original Evo, not once did I have an issue. And by an extremely heavy user, I use it to locate 20-40 (depending on the day) locations a day, every day.
I bought the Evo 3D on launch day, for the first week or so the GPS worked great, it lost the signal once or twice, but I ignored it. Then one day it kept losing the signal a lot. I’m talking like 5 times in an 8 mile stretch on the same road. It started taking forever to recalculate, there was an extremely noticeable lag (it would say for example, my next action was a left turn 1.3 miles away when I already passed the road I was supposed to turn on to). Not only did the signal drop out while driving, but it would drop out while just being parked, and then it takes forever to require the signal. And my personal favorite when your five miles into a 17 mile long run ON THE SAME road/highway it will just randomly recalculate. What’s up with that? i assume these are the same type of issues everyone is having?
Now I took the phone back to the Sprint Store, I was within 30 days so they swapped it out for a band new one for free. The new phone worked great for about 2 weeks, and the same issues started happening, but a lot less frequently, it was tolerable, but so far this week it has been pure hell. This afternoon I lost count, but I was up to 157 instances (this week alone) where the GPS has lost the signal, rerouted me randomly or incorrectly, failed to properly update me of my next action, or just took forever to acquire the satellite signal. This week has been extremely aggravating, to say the least.
Here is one thing I noticed this afternoon, I’m not sure if this is just a fluke or what. I always keep my phone connected to a car charger when driving. For some reason I unhooked it and was running on battery, the GPS worked perfectly to get me from my last two stops of the day, back to work, a total of about 60 miles worth of driving. Not one drop out, not one bit of lag. Prior to that I couldn't go 5 miles without some type of problem. Tomorrow, I will be in an area I’m sort of familiar with and won’t need the GPS much, but I’m going to map out my stops anyway just see how it behaves on battery, until the battery gets low. That final 60 miles today took me from 100% to 55%.

How is the GPS working on the Samsung Galaxy S 2?

I'm sure everyone knows about the GPS bugs that plague the first generation Galaxy S. I've read the SGS 2 reviews and they said the GPS issues have been fixed, but can I get some opinions on whether anyone experienced any GPS issues? Is the GPS on the SGS 2 as accurate and good as the one on the iPhone 4?
Works fine. Faster lock than my IP4.
Its much faster than the Galaxy S1. I found the GPS to be close to useless on S1. On my S2 its close to perfect
Sent from my GT-I9100 using XDA App
Works great and picks up signals inside buildings.
I had the sgs1 for about 6 months and now the sgs2 for about 3 weeks. I was soooo disappointed with the first sgs and like you I was unsure if I wanted to give the 2 a try...
Well I read a bunch and it seems that most people are happy so I bought it...
I can say with out a doubt that the GPS is way better on the 2 than the sgs1. I could not use Google navigation at all with the sgs1... it was useless and could never lock on and would have me blocks away from where I was. I've used my sgs2 GPS with Google navigation on more than a dozen trips /drives and it has always been spot on and never had me in the wrong location.
I will say that lock times are very slow when Im driving
Sent from my GT-I9100M using XDA App
I run every other day for an hour or two, I use runkeeper, also when out hiking I use mmtracker to read my o's maps, I can safely say especially with runkeeper the gpx routes recorded through the SGS2 are far more accurate than the iphone4 even managing to stay accurate whilst running through the forest, actual initial cold starting is about the same if not slightly faster with the sgs2. Oh yes and practically every time I recorded a run with the iphone4 through a certain part of my forest run it would create a spike where I was apparently running at 250mph hmm not sure I am that fast, but the sgs2 always keeps an accurate smooth record, hope that helps
for me, flaky. some days i'll get a lock within a minute and then it's fine. this morn and yest - takes ages to get a lock.
basically, ymmv
Download FasterFix. You can choose from a list of servers. Choose the country closest to you or, if it is in the list, your own country. This way you'll 'half your fixtime' so it connects faster to GPS-Sat.
It's like using the aiding sensors (e.g. WiFi).
I get a fix in >10sec max.
Hope it helps.

i think gps on SG2 is far from perfect. It's "OK" but i had much better gps on my previous phone (HTC Hero)
What is the average time for a fix, for you guys?
Sent from my GT-I9100 using XDA App
Mine takes between 10 seconds and a minute. Sometimes it just sits there doing nowt lol.
Xperia X10 used to lock in 10 seconds every time, but the rest of that phone was slow lol
The only time I have ever had a problem getting a fix, I simply opened up google maps and it seemed to get a fix instantly then returned to my other gps application and all was ok.
First thing in the morning outside fix within a few seconds
Indoors sometimes can take a little longer, but never more than about 10 seconds
I use GPS a lot

I guess you said this to clarify that you've got good statistics, but a very interesting thing is that if you use the GPS often you likely get shorter fix time
The reason is that if you used the GPS recently (within hours) the cached GPS info is more accurate so the GPS doesn't need complete messsages to determine the position (it takes 30 seconds to send one complete position message from a satellite), and if you get interruptions you need to wait even longer, that is why it sometimes takes more than a minute to get a fix.
A-GPS also helps fix time in many cases.

Same thing happened to me.
Absolutely brilliant.
90% of the time it gets a lock within 30 secs , there's been sometimes when it needed a restart to get gps working properly but that's down to an app I was using previously which messed things up a bit, but on the whole I very happy with it.
The seamless integration with google maps is great. The external speaker is plenty loud & clear enough to hear the instructions but would like a less robotic sounding voice, re routing is quick & so far its been 100% reliable.
I have a built in gps system on my Land Rover but I almost always use the SGS2 gps over it. I used to have the SGS1 but the gps on that was a piece of crap. Gps on HTCs, etc, are probably just as good/better/worse, I don't know but one thing I'm sure about is the speaker volume would never be as loud & clear as the SGS2.
I get a lock up to 4m accuracy. My Captivate always had about 1500m accuracy and couldn't use it. Using navigation works perfectly on my sgs2

Excellent
Like others here, i suffered from the original SGS gps nightmare
SGS2 gps has been great for me, able to use google maps/navigation/RAC app all without problem
I didn't realise how much location based services I used untill the problems with SGS gps clearly highlighted this. Now, with my SGS2 all is good.
Is there an app like the LBStesmode for froyo that I can use to change/check the gps settings?

battery life in detail

PLEASE MOVE THIS THREAD TO GENERAL MY APOLOGIES
I know battery life issues have been talked to death but...Here's a new perspective:
so I have been doing some experimenting with my amaze in terms of battery life and asking my friend who works at T-mobile regarding his SGS2...He says his battery life seems to be pretty crappy too, marginally better than the amaze....so, I hard reset my phone and I did not sign into google, left my phone on airplain mode, basically I did not set up anything...I turned off wifi, and data everything was truned off...I went for 10 hours with only 2 percent battery drainage...then I signed into google....and in a matter of 10 minutes I went from 98 percent to 92... Watever is eating the battery up is not the phones hardware fault or the screens fault... I turned off background data sync and it seemed to make little difference...It seems the google programs or any program that needs internet connect regardless of syncing or not will have significant effect on your battery life...between 4g and wifi I saw little difference in battery life drainage...my phone signal is completely green so I cannot blame the signal... I cannot possibly kill gmail, market, maps etc...these are programs I use constantly...lets hope with the ICS update some of these sofware issues will resolve...
google needs to start managing applications better and not leave a bunch of applications running in the forground and background...
I've heard different theories regarding task killers...some say it actually worsens battery life since programs keep wanting to restart and some say it saves battery life...can anyone elaborate on this? I have juice defender ultimate, it seems to make minute difference in battery life as well.
PLEASE MOVE THIS THREAD TO GENERAL MY APOLOGIES
Display is the biggest factor obviously and then its data transfer or anything that has to do with transmitting signal.
like every other phone the 100% lasts for a long time then after it drops it drops quickly. So your analyses is flawed since it already dropped from 100% and then you switched data on. There are apps that are constantly sending data and the sense UI kills the battery a lot too. Thats why AOSP roms are better for battery life.
Juicedefender helps
setcpu helps
managing your apps helps
changing your background to black helps
I've tried juice defender, um... I would suggest you read about instructions on flashing a custom ROM I'm on quiksense and when 2.0 comes out I heard xboarder's got some really nice improvements with the 1.4.1 version I almost doubled my battery life. My phone used to go down to 50~60 idle over night, now it's about 90~ idle over night.

use JD ultimate and set the apps to work with screen off.
you can get a telus or wind model without the tmobile branding
i think you can change the bootanimation with temp root because it's just a file? I'm not exactly sure about that one though.
apple sells their iphone to ATT
as htc sells their phone tmobile
tmobile probably request a branding on it with a higher cost.
att probably reject the higher cost because they're already losing money when buying the iphone from apple (i think i remember i read it awhile ago) and make money off data plans.

for JD you want to click on the app thing twice so it goes to enable/screen off not just enabled. But yeah i noticed that sometimes it works sometimes it doesn't
not sure where the bootanimation and sounds is it at, i never played with it. You should check out the themes section, you can download the zip and browse through where it goes.... other than that there might be other threads with the instructions on where it's at.
You may want to try an AOSP based rom, (if you rooted)
I was getting 18 hours of use with 36% left, Medium usage (ie browsing, texting)

[Q] Stripping down a ROM.. Phone function removed?

I have an old Nexus One doing nothing and was thinking of using it as an mp3 player.
How much of the android os can I remove to basically just have it functioning as an Android mp3 player?
Removing the phone functions and other apps should give me extra battery right?
Lol just buy a mp3 player.

And where will the fun in that be?
Stripping down the system can help you learn about how it works, and skills and experience you'll gain may serve you, long after the device has been recycled.
This is why he has posted the question in a developer forum, and not a fan one.
On topic
Seems like a neat idea, but as far as removing the phone functionality to gain extra battery? Why not just use Airplane mode? You'd never know when you might need just a phone.
Other than that, I'm sure that you can remove most of it (the apk's that is), and i suppose you could make a script to startup Music.apk upon boot.
I know that the emulator is slow on most normal PCs, but I'd advise trying what you want on the emulator first, just in case. You can even make a list of what you are removing as you go, so you'll know what can break the system, and what isn't going to have any effect.
Thanks kurdo_kolene didn't think about airplane mode!
Think I'm going to have to play around with this the weekend to see what can go and what has to stay!
My nexus one has a broken power button so swapping out the sim cards is not possible unless I have a charger to power it back up. So I had no plans of putting a sim card in it but since airplane mode should shut all the radios off it should be fine to leave the basic phone functions as it is.
Just flashed [ROM][AOSP][2.3.7] OxygeN1mod FINALE! [2011.12.10] which already is pretty barebone
But I went about removing apps until it wouldn't boot... But it still boots
59mb RAM used / 315mb free on boot.
Launcher has just 4EXT Recovery, Browser, Downloads, Market, PowerAMP, Root Explorer, Settings and Superuser!
Removed all the phone, contacts, sms/mms, calendar, email the lot and all is fine.. Expect when I removed the Phone.apk and had to reboot but no problems since.. Will have to fully charge the battery and see how long it will play music constantly now!
I would guess that a big part of those 59 MB is allocated to the dalvik runtime. I've used DSL on an old PC and after boot it used 25-35 MB RAM.
Pretty impressive nontheless.
If mplayer made a native version for arm devices, that could be used without a launcher, that would be even better.
You might want to install Android Terminal, in case you need to reboot and you're away from the PC.

Yer sorry mods I see the other forum after i posted but couldn't find a way to move it myself...
Anyway I was planning to test the standby time but I think I might just skip that now...
94% after 1d 13h 49m
Phone idle - 95%
Display - 5%
So I'm going to drain the battery then do a full charge and leave it playing music till it dies and see how long I can get of continues music!
Also the phone signal bar in the battery stats is a full yellow bar... What does that mean?
The others are small little blue bars next to Awake and Screen on...
That's pretty good.
I'd wager that the longer the display is off, the better battery life you're gonna get.
I have personally seen ho the huge display on my Streak 5 drains the battery without doing anyting even marginally intensive.

I have an old Nexus One doing nothing and was thinking of using it as an mp3 player.
How much of the android os can I remove to basically just have it functioning as an Android mp3 player?
Removing the phone functions and other apps should give me extra battery right?
Click to expand...
Click to collapse
I am also looking for the same, i also need camera, so my device ll be an mp3 player + camera
could please upload the rom you customized?
