Null Black Wallpaper

Been using this app for years. Great that it uses a wee bit of RAM instead of draining battery by going the CPU route, like with typical wallpapers. Easy as going to wallpaper settings and setting this (live) wallpaper. Great work, dev!

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.

OK, am I missing something? I downloaded and where the heck it went..... Who knows. Waist if time, don't do it .

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

I use this little gem on many phones, but right now i use galaxy a5 2017 model and when i try to set it like live wallpaper it say: app is not installed. Any solution please? Thamks.

Exactly what I was looking for since live wallpapers started eating 20-40% of my battery through SystemUI

Am I missing something please sir dev? It worked great for first several hours and now it constantly resets to OEM default blue? Thx for any clues sir..

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.

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!

We need more smart people developing simple and smart but needed apps/utilities etc...too much trifling BS out there.

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.

I have successfully downloaded it but..it shows uninstall option instead of showing open it??? Whaat?

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!

Nice well done.

Where it is its now you are crossing your limit i am getting anger really a bad zero rate app

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

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

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.

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.

Not sure how it does it but my battery life has improved dramatically. Thank you! Samsung Galaxy Avant Kitkat

I have a poor eye sight. But since I got this wallpaper, everything seems clearer even in daylight.

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

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.

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'.

Downloaded several times.never shows up anywhere to apply. Uninstall several times.

Well I guess it's extending my battery. I don't know..

Works great on my Galaxy S6!

Great idea works well - love it thanx.

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

Not so bad but no too good either

Blackest black ever. Love it!

It does what it says it does. If you are a battery maniac like me download this now.

Does it not work with Nova launcher

Phone feels faster and seems to save battery

Lets hope it does wat the creator says -saves batt life n display

For all you people that can't find or open this app go to your settings to wallpapers

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...
