Wow. I didn't expect this to work..
It does what it says it does. If you are a battery maniac like me download this now.
This is the app which really performes according to specification. Works well on my galaxy s6 and its performance has improved dramatically. Thank you developer. If l had a million dollars would pay for this
The black is so good and enhanced.
Nice well done. 😊 does it actually not light up the screen????(it still feels like the screen is kind of lit even in the black parts)
Does nothing, which is exactly what it should do. I did have trouble finding it though, for anybody else who can't find it. Go to 'settings' then 'wallpaper'.
I set this wallpaper on my xperia and it immediately opened up a black hole right in front of me. Upon entering it, I discovered a world 1000 years in the future that had invented mobile sized fusion battery's that are totally safe. I had one fitted and my phones going to be fully charged for approx 9 millenia, so yeah, all good. Also the chicks were really loose and the alcohol was free! I only came back to this time because I owe quick quid a tenner and with the interest added I owed 1.9 trillion pounds
Null is Black
Its not the absence of light that makes this black, it's that theres nothing there at all. So you use less power.
Perfect. Exactly what I wanted
I thought a simple Google search for black wallpaper would be simple. Not so much I had an issue finding a true black wallpaper then I stumbled across this app and it was exactly what I was looking for.
It's works and save my better power, but could you please tell me how much ram power it takes to run, i have only 512 mb ram, so asking, thanks.
Loved it. Excellent..
Who'd have thought getting a black background could be so hard to find. This is a great product...
It does exactly what it supposed to do. PS: it downloads to your live wallpapers. Took me some time to find it
Only for those that seek simplicity
I own a note 4 is my office on the go, I do anything and everything on my phone. So a simple black Wallpaper that with no distractions is the best option for me
Design for AMOLED
For all AMOLED users, this is a must-have wallpaper. Your screen will looks awesome. Just black, but very classy. I've been using it on my Galaxy S4.
I had a black or no wallpaper but can't remember how I got there so when I lost it by accident, this was the answer
DO YOUR PHONE A FAVOR! DO IT NOW!
Thank you, Roc! This simple WP is far and away the BEST thing I've ever done for my phone. It literally started cooling it down the moment I applied it, and I could feel the temperature falling dramatically while the phone was in my hand. The intensity of the "black" doesn't compromise the phone's eye-appeal either but, in fact, enhances it. Black is classic and elegant, and icons pop out against this stark background. Now that I've wrapped my mind around exactly WHY this works as it does, I'm astounded.
Normaly I don't leave comment for these kind of apps. I was surprised to see today that this Null black wallpaper and screensaver has kept battery on my note 4 at 75%. Normally a this time my battery would be at 40 to 45%. Honestly I am surprised how much battery one can save just after using blavk screen and recommend it further at least for a try.
Love the concept...great work
We need more smart people developing simple and smart but needed apps/utilities etc...too much trifling BS out there.

I can't make it work
I've tried to open it but it doesn't, the app is there but it doesn't function... Any help please...

Excellent on Galaxy S4
At first, I thought it's just the same as setting a black wallpaper but upon reading your responses to the negative comments, it is clear that this saves battery since the live wallpaper service runs on ram and does not consume power. Thanks for this wonderful app.
Battery lasts & lasts
Do I miss having a nice background on my home screen? Sure. But I just got back from vacation and never once while I was gone did I run out of battery power during the day. I wasn't the person huddled next to an outlet in an airport or museum. That makes it worth it every day.
I don't know what this wallpaper does, but I have gone through the whole day without having to recharge and I am still on 50 percent.

Runs perfect on my SGS2, but on my Nexus 7 tablet.. shows some colored dots at top left that flicker when I scroll desktop screens left or right. Very annoying
Love that it's Open Source
It's not a color, it's a lack of any color, it is null, it is transparent, it's black. Thank you dev!
Installed; battery now lasts longer.Nuff said. Thanx.
Best black WP ever!!!
I have samsung galaxy s4 and it was draining too much of battery life, so i decided to install this application and i've seen an evolution in the battery life and in the performance of my device. THANK YOU ROC
It Actually Works
Not sure how it does it but my battery life has improved dramatically. Thank you! Samsung Galaxy Avant Kitkat

Well what can you say Black is Beautiful - and this proves it for me. Paint it Black, Back in Black, Fear of a black planet, Black Flag, Big black - we are in the Black. Black to the Future well maybe not that one.

This may seem stupid, just downloading a whole app to have a pure black wallpaper, but I have to admit it's actually worth it. -1 star for not including lion cock.
Didn't Think It Would Make A Difference
I have the Samsung Galaxy Note 4 and since it is quite powerful, I figured this wouldn't improve its performance that much. After this [lack of] wallpaper installed, I instantly noticed a smoother and much quicker transitioning between screens and apps. Apps themselves are performing much quicker than before. I never leave reviews but this was definitely worth reviewing. If you don't care about having a flashy wallpaper, install this now! You won't regret it.
Its a blank screen..
Awesome. A black screen, with my apps on top off it. My CPU is running smoother already. Remember to restart your phone after setting this app. Then check your CPU performance...
Yes a proper blank screen!
Why they think we want their stupid wallpapers I'll never know. But I have never had so much trouble getting rid of it before! This is the solution to your problem - fellow wallpaper haters! Although why such a solution is needed (why not just a "no wallpaper" option?) Grrr. But full marks to this app for getting it done.
Not only saves battery life, it's also improved the performance of my phone. Everything runs faster. Very simple, elegant solution, and with the right icon packs, I don't even miss having a wallpaper!
I honestly love the idea but I can't give a perfect rating since it doesn't cover the whole of my screen. Zenfone2 on android 5.0. Please fix it, thanks devs!
