From personal experience I can assure you its

As waterproof as it should be. The obly review that managed to make me buy this phone was this: dcrainmaker.com/2011/09/hands-on-review-of-sony-ericsson-xperia.html

This guy actually makes a real life test of the phone. I myself work at construction so I have cement splashing on it, and all I have to do it take a shower with it to make it aaaaalright :-P

Regarding the defy... Well its got a larger screen, but it looks more flimsy than the Active. What sorta put me off on the defy is the quality of the power and minijack rubber plugs. They would only last not so long on my hands... All you have to do on the active is change the back cover. The only drawback for me being accustomed to a physical keyboard amd a 3,7" screen of my Desire Z is the size of the onscreen keyboard of the 3 inch screen.

Also expect somewhat better battery life on the Active than the defy. Almost 50% of the battery drain is from the screen, and having 60% less pixels on a screen you easily go through 2 days of moderate-heavy use.
[Galaxy S II Q&A, Help & Troubleshooting] Upya:
Hi there,

I hope you may be able to help me or point me in the right direction.

I got my S2 from Virgin a few months ago and absolutely love it, my wife although at first being sceptical of 'smartphones', saw the light and asked me if I would buy her one if she sold her Cowon J3 pmp.

A friend of hers upgraded last month and received a S2 and decided she didn't like it, so I just bought it from her at a good price.

This S2 was from Orange, it has an Orange logo on the rear and although I have performed a 'factory reset', it is still full of Orange apps.

Both myself and my wife are on Virgin Mobile and are happy with this network. I plan to get my wifes new phone unlocked in the local market over the next couple of days so she can install her Virgin mobile SIM card, however I would also like to remove all of the Orange branding and apps if possible?

So my question is, is this possible and what would I need to update for her phone to be the same as the one I got from Virgin (which has a distinct lack of much noticable branding)?

Also if this is possible, should I do it before or after I get the phone 'unlocked' in the local market?

Sorry for the newbie questions, I have had a search of the site, but being a relative newcomer to smart phones myself, I'm not sure what I should be looking for.

Many thanks for your help in advance.
[Galaxy S II Q&A, Help & Troubleshooting] sageandonion:
Search for de branding and look for the xda guides. Mine was orange and i couldn't wait to get rid of their sh*t. Theres also an app to unlock the phone which i used as well (free) its called 'galaxy s unlock' and worked a treat for me. Good luck.

To install an unbranded firmware. It relatively easy, just read the instructions carefully.

To stay on official update channels, I'd say install XWKI4 and the 'XEU (UK)' version.

While your at it, follow the root guide in the same link and then get '[root] Galaxy S2 SIM Unlock' off the market to obtain your unlock code. Its free.
[Galaxy S II Q&A, Help & Troubleshooting] Upya:
Thanks guys, I'll check out that link and see how I get on.
[Galaxy S II Q&A, Help & Troubleshooting] Upya:
Thanks again, I have just flashed the firmware to XWKI4 and the 'XEU (UK)' version.

It was very straight forward and not half as scary as I thought it would be and best of all, all of the orange bloatware is gone!

I am going to attempt to root it now, so I can try that unlock program, I just have to figure out what the ADB drivers are first, lol.
[Galaxy S II Q&A, Help & Troubleshooting] shaq1907:
After root your phone you can also uninstall preinstalled applications with SystemApp Remover.
[Galaxy S II Q&A, Help & Troubleshooting] Upya:
Thanks for your help again guys.

I tried '[root] Galaxy S2 SIM Unlock', but that could not find an unlock code. However 'Galaxy_S Unlock' worked a treat.

The mrs is now very happy with me!

Question is, do I unroot her phone now or leave it rooted???
[Galaxy S II Q&A, Help & Troubleshooting] markdj57:
I did the same with my three branded sgs2 and now works a treat.

You might want to get the ice cream sandwich keyboard from the market if u don't use swype, it really is excellent.
[Galaxy S II Q&A, Help & Troubleshooting] Upya:
Thanks for the advice, I have just installed it and see how it copes with my fat fingers over the next couple of days.
[Galaxy S II Q&A, Help & Troubleshooting] Genrauser:
Keep it rooted and install Titanium Backup (freeze ****/app. backups), Droidwall (firewall, don't let games and other **** connect), root explorer, adfree (bye bye adds), etc.!

I just got CM7 mod on my phone and I'm loving it. However I'm curious to know an easy way to find other mods out there for the Inspire. I've seen mentions on this forum of others but it's hard to sort through what's what so I'm looking more for a definite listing of what's out there for other mods. Thx.
[HTC Inspire 4G] MMM-BACONSTRIPS:
What do you mean "mod"? As in like a theme? or like APM and transparency mods? Since this is a development site, it is expected that you do some research on your own. There are plenty of CM threads out there that can point you in the right direction, don't be lazy, reading is fundamental!
[HTC Inspire 4G] coreyslancaster:
I meant to say ROMs not mods. Is there a list of available ROMs for Inspire?
[HTC Inspire 4G] MMM-BACONSTRIPS:
Again, I must stress to you that reading is fundamental, I get it that you're new to the site (my observation based upon your post count) and welcome! I hope this starts off what should be a mission to educate yourself. Again, this is a dev site where everyone assumes and expects you did the proper research before asking a question. The so called rom list you speak of, exists in the Dev section in one of the stickies. I don't think it's as up to date as it should be but that isn't a dig at the mods. The real list lies in the collection of threads in the dev section. Start reading.

edit: please don't ask here or in a new thread "what is the best rom" or "what's the difference between x and y" these questions will result in numerous members yelling the same thing at you..."ONLY YOU WILL KNOW WHAT IS BEST, TRY THEM OUT"
[HTC Inspire 4G] mateusm:

[Samsung Galaxy Nexus] Davidsmonkeyroost:
Some tidbits: The whole phone was warm, front and back. Not scary hot, but like a nice hand warmer. The screen shots were actually done after I connected the charger and restarted the phone. You'll see the graph shows it starting to charge, but all the stats are for when it was last on the battery - in the test.
[Samsung Galaxy Nexus] gogol:
Thanks for testing this.

How do you define min brightness?

The black color, do you mean #000000 hex color code?

That will last days!
[Samsung Galaxy Nexus] x.Orville.x:
excellent thread that's it's about screen time on no idle time
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Not too scientifically - I made it black in MS Paint. It's a JPG. I tried it out in portrait and landscape on full brightness and I can't see the edges of anything on the screen, so it's as black as the rest of the black in Gallery. If you have a better way, then I'd gladly take a 16x10 black image if you think it is more black.

Min brightness will be using the brightness slider in settings. I haven't rooted the phone so don't see any way to get it lower. I tried the app "Dimmer" but it's the same brightness as far as I can tell as min setting. Also I figured the min setting was relevant to more users than something they can't easily get to (or probably see on screen!).

Do you have any suggestions? I want to root, but my home PC can't see my GNex. It's being a pig about it and I haven't got Broadband ATM... Hope to root as soon as I can.
[Samsung Galaxy Nexus] Nebucatnetzer:
Just a quick input. If you just show a picture for 5h how does the cpu perfom in this time? Isn't it really bored?

In addition if you switch it to air plane mode it doesn't use any power for transmitting a signal. I know this point is really tricky due to the fact that not everybody receives the same signal strength.

Isn't there a more realistic way to test it? Like a combination of stability test and the white picture?

Or a slide show with specific pictures, for example a picture with lots of green, one with a lot of red, one with blue, one with white and one with black?

I really like the idea but if we could create something like a standard which tries to simulate real usage that would be great for future testings.

So that we could say something like:

Galaxy Nexus with Vanilla Android -> 5h with XDA battery benchmark

Galaxy Nexus with CyanogenMod 9 -> 5.3h with XDA battery benchmark

We could compare different settings and see how good they perform based on a "standardized" procedure.

Hmm is this probably a bit too much?
[Samsung Galaxy Nexus] pewpewbangbang:
I like the idea of a standardized battery procedure for XDA.

Only thing is, i feel like just web browsing would give a better idea, mostly white website sites and it uses data and CPU/GPU still to give real world usage results.
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Hi Nebucatnetzer, I get what you're going for and think it would be a great test. My original goal was just to see how much of a drain the screen was. I used it on Airplane mode as I do not want to have any other drains diluting the result. As you say, signal strength changes, and so this becomes an uncontrollable variable. I'm only showing a white image as it's the most uniform full power test of the screen I can think of. As the display is RGBG, maybe a greenish white would draw more, but I can live without that - web pages are predominantly Plain White and Text in ICS is white.

I actually think that 9%/10% drain for Android OS may be a bit high for 5 hours. I think Just Pictures may be the cause for it as it does every minute change the image in a slide show... to itself...
[Samsung Galaxy Nexus] Nebucatnetzer:
It was one of the things which annoyed me the most here. Everyone says he has the ultimate tweak to save juice but you never really could measure it.

We probably have to skip the data part due to asimilar signal strengths.

And it would be really cool if we could find something which works for every phone.
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Hi! I'm not trying to do a real world test as such. I'm trying to find out how much of an impact a white screen has compared to a black screen. I have a suspicion that the Black screen will draw more than it should do. I've been using my phone on Auto Brightness and at night, min brightness and have found the screen is caning the battery. There's more to the screen than the AMOLED - there's also a MIPI Framebuffer controller, plus whatever interfaces that has to the rest of the phone.

I'm aware that ICS and the other internals of this phone seem quite efficient, so any savings I can make on the screen (which really does suck the juice) should translate into big run time gains... Surely...Right?

If it turns out that there's very little different in battery life between a Black screen and a white screen, then I'll crank up the brightness to revel in its retina destroying beauty. If there is a difference, then i'll stick with my black homescreen background....
[Samsung Galaxy Nexus] pewpewbangbang:
The black screen shouldn't draw any power virtually as long as its truly black. SAMOLED functions where black doesn't turn the pixel on so no energy is used. I think the black test has been done by someone, you can probably google it.
[Samsung Galaxy Nexus] Nebucatnetzer:
We we aren't criticizing you specific we just hijacked the thread a bit sorry for that :D.
[Samsung Galaxy Nexus] Davidsmonkeyroost:
would be good if someone could make a benchmarking program which pumps out signals in a set pattern on all devices at set frequencies and at a few different power levels. It would't need to wait for a response from any cells or WiFi routers, just talk to itself and only itself. Maybe this would need too low level access to work, below root.

Then you'd have your predictable Radio part of the test. If it's even possible.
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Well, I hope a black screen will draw considerably less. We shall see. Or it will be a revelation... Or everyone will get to witness me finding out that my phone is defective. Hahaha... oh...god I hope not...

I may run the black test overnight. It should last the night. If it doesn't I can always hook it up and check the last "On Battery" status as I did earlier. Then I can run two tests tomorrow!
[Samsung Galaxy Nexus] Nebucatnetzer:
This sounds more than difficult. Not a clue how one could do this.

As soon as I have my device I'll probably start a thread where we can think about a standardized (what a stupid word) battery test.

Curios how your second test goes.
[Samsung Galaxy Nexus] ptscon:
Instead of the black screen test, amoled screen:), you could do a white background with black text. This would give better overall real world stats.

[Samsung Galaxy Nexus] Davidsmonkeyroost:
Second test - black on lowest brightness - is underway.

Some bad news, which you may already know about: Black isn't black. It's very dark, but the phone isnt switching all the pixels off. I took a photo with my SLR in the dark but can't upload at the moment, will upload tomorrow.

Just took a sneaky look at the stats.

85% 01h26

The draw is 85% screen and 16% Android OS. Yeah, I know they don't add up, but that's what it says.

So far, the draw is higher than I expected for lowest settings with a black image. Odd. The phone isn't warm though, like when the screen was showing a white, max brightness image. It's cold.

Sure hope it doesn't start moaning about running flat whilst i'm asleep...
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Last check before I go to sleep: 82% 02h05

Same split of 85% screen and 16% Android OS. Who says percentages have to add up to 100?
[Samsung Galaxy Nexus] ptscon:
Most likely rounding bug.
[Samsung Galaxy Nexus] gogol:
You should consider setting the min brightness to a value that is still applicable for viewing. For example brightness at 5% or 10%, and not at the lowest setting. Because people hardly use that lowest brightness setting. I dont know if this is possible with default setting in ICS, but I use Widgetsoid to set brightness at certain level. With my current Nexus S, I set to 8% and I can still see comfortably :)

And do not use an app like JustPicture, but use the default launcher background. Remove everything from the screen to make as minimal asossible with everything default. This is to remove the app influence. Then set the screen to not timed out.

I did this similar test in the past with Amoled screen of htc Desire :)

I like this idea of standardized XDA battery test. Just an app that do this:

Save settings

Set screen time out to no

Set to airplane mode

Turn off anything else like bluetooth, gps, etc.

Choose test mode

... Pure white test at max brightness

... Pure white test at lowest brightness

... Pure black test at max brightness

... Pure black test at lowest brightness

... Simulated web page at max brightness

... Simulated web page at lowest brightness

Do the test

... Record battery drain every 30 minutes

Restore settings

Thats for a start :)

The simulated web page is just an image with text and some images or even animation.

Any developer interested? :)

Just woke up. Black min:

[Samsung Galaxy Nexus] Davidsmonkeyroost:
Good idea. I do have my concerns over Just Pictures elevating the Android System part of the test, but it should be consistent. I was worried that JP might have a very very dark background image which would show at the sides of my black image, however the photo I took last night shows that the entire screen even the gaps between the android buttons is the same uniform dark grey.

[Samsung Galaxy Nexus] matt2053:
Guys, stop suggesting he use normal brightness settings or browse the web etc. That would introduce variables that would ruin the results. He's not testing to see how long the battery lasts. He's testing to see if white vs black display images affect battery life.

[Samsung Galaxy Nexus] Davidsmonkeyroost:
Its crap in my camera body. When i point it downwards and do a long exposure, i sometimes get dust in the photo.

The phone screen is perfect, not a dead or misfiring pixel to be seen.

What you can see is the greenish glow on the screen. This is as black as the screen goes. It isnt switching the black pixels off.

Please bear in mind that this was a 1 second exposure, ISO 1600, F1.4 in a darkened room, but still, on is on.

Will be finishing it next week. Check back in a few days.
[Samsung Galaxy Nexus] wonshikee:
Something interesting I noticed is that if you use a #000 image or a webpage, it's not true black - just a very dark pixel.

But if you open up youtube, let the video finish and don't touch it, then view it in landscape mode - the black pixels appear to be turned off completely, because you can see some stuff behind it. You have to be in a very dark room to do this.
[Samsung Galaxy Nexus] just4747:
Hey OP, how come in the pic of the white screen (http://attachments.xda-developers.com/attachment.php?attachmentid=798046&d=1322509388), it looks very much like a pentile screen look which this phone is supposed to not show. It has those fairly large ugly grid lines showing. Make sure you enlarge the browser pic to 100% to see it.

Is this actually visible on the screen in person???
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Hi Just4747. I wouldn't worry too much about any shapes or lines you see in this picture - you can't see it in real life. It'll be from the vertical lines on my cameras CCD sensor not being quite parallel with the vertical lines on my Phone, creating diagonal lines in the picture, kind of like when you see someone with a stripy shirt on TV. Makes your eyes hurt...
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Hey wonshikee, your first point is shown in my long exposure photo in the OP, it looks green in the photo, but it's really a dark dark grey.

The Youtube experiment you mention sounds interesting. I'll have to try this tonight with my SLR to see if it's captured as proper black. What happens if it displays the navigation buttons? Does the screen become very very dark but still on again?
[Samsung Galaxy Nexus] dinan:
About the "dots" or "spots" on the black screen - I've seen this on every SAMOLED screen and I suppose it's normal since you can't see it with the naked eye really. I've seen it myself with my naked eyes but it was tough... and you really have to look for it, I wouldn't be too concerned.

Also curious how the black minimum time and white minimum time are so similar?
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Hello all, So I've posted the results of stage 3 of 4 testing and it's interesting...

Let's compare Minimum brightness Black Screen with Minimum Brightness White screen.

Dim Black: 10h47 run time

Dim White: 10h20 run time

That's just a 4% improvement in run time by switching from a white screen to a black screen. That doesn't sound enough.

Looking at the Power split both times the power draw was 85% screen and 16% Android OS. I would have expected the Dim White to have a greater percentage Screen draw than the Dim Black.

So I can't explain it - Is the GPU counted in the "Screen" total? Is the MIPI controller converting the video signals into something the screen can display a power hog? Or is the power meter inaccurate? Dunno.

Anyone got their 2 pence/cents worth?

Hopefully the next test which is Full brightness Black Screen will show a bigger variance to Full Brightness White Screen. This would show that the the AMOLED part of the screen is the biggest draw when at full brightness. If it doesn't and the run time number is similar, then it's something else being very inefficient.
[Samsung Galaxy Nexus] Davidsmonkeyroost:
I'll take 2 photos tonight, rotating the camera between shots to see if the dots are on the camera or on the screen. I'm pretty sure it's just in the camera body as I can get them on a white wall with a large enough aperture.

About your second point - yeah, I'm confused that the run times are so similar, when they really shouldn't be. See my post from about 15 minutes ago.
[Samsung Galaxy Nexus] dinan:
I think either the application used as the slideshow or the general CPU processes while "awake" must account for most of the power usage because with the screen fully black it should last very long considering older phones using NoLED could last for days displaying those notifications on the screen which is essentially a black screen with a red dot that moves around. Not really sure though... still, 10 hours of screen on with white is pretty damn good =)
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Hi, See attached the screenshot for NoLED on the GNex. As usual, 1 second ISO 1600 F1.4 shot.

Black isn't black.
[Samsung Galaxy Nexus] Davidsmonkeyroost:
I was wrong - The spots ARE on my screen. Can't see them with the naked eye - at least not mine - but the Camera can see them. Check out the attached comparison shots.
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Hello again. I was running the final test today - Full Brightness, black screen and 7 hours in all was well, then I went to work and at some point the screen went off. It was doing well looking at the graph, headed toward 10 hours or something like that, but will have to re-run.

Out of curiousity I took two comparison shots of Full and Min brightness with a black screen to see if the "Black" was the same level of grey on both. It was. See attached.
