Android application launcher icon has a black background - android

I saved an image in photoshop using save for web, 24 bit png, with transparency checked.
I then generated my icons using the Android Asset Studio.
My launcher icon has a black background on my device (Captivate), but does look fine on my emulator.
Any advice on how to get the icon to not have the black background on my device?
Thanks in advance!

Save it as a 32 bit png, that way you get the full 8-bit transparency.

Samsung TouchWiz is what's putting the icon backdrops on.

What shape should Unity app icons be and which icons are necessary?

I am making a app for iOS and Android and have a couple questions about the icons. First I know I should make Android icons a square because the launcher cuts it into shape. Does iOS do the same or do I need to have the icon in the proper shape? If I have to add the shape on my own what would the border radius's for each size be? Second do I need to use the adaptive icons with 2 layers or will my app still work on those devices using the other icons?
For android the app icon size 512 is recommended
For iOS the app icon size 2048 is recommended
Unity is capable to generate other size what all are required.
You can use this online tool to generate all size app icon

It will create shape for iOS too that is 180 radius for corner as iOS do not support alpha in app icon, for android you can use square or with alpha corner, both is ok.

Unity: Colors are Brighter on Android Device

I have an Android App I´m developing in unity. Colors look just fine on the game editor, but when I build the app and use it on My Samsung Galaxy S4, all the colors seem to be brighter than on the Unity Editor. I have all my images on True Color. Even the background colors and button colors of the UI get brighter.
Can anyone tell me how to get the same colors I get on my Unity editor when I build the app on my device?
Thank you
Move your game pictures from your laptop to your mobile device then you see even with same pictures they looks different and it's because difference to their quality and it's not unity or your fault.

Launcher icon too small

The launcher icon of my app is downsized, it's smaller than the other icons. I even tried to copy the launcher icon from my other app and when I put these apps (with the exact same icon) next to each other, one icon is smaller.
Both apps have the same minSdkVersion and targetSdkVersion. It's quite weird, what could possibly be the problem?
I tried reinstall, phone restart and two launchers, the default Moto G launcher and Google's KitKat launcher.
Google launcher uses xxxhdpi drawable directory (192x192) to display app icons.
Plus, make sure you dont have an big padding transparent pixels around the icon shape,
I suggest you to use Image Assets to generate your app launcher icon. it comes with Android Studio and Eclipse.
File -> New -> Image Assets
It was my fault, the icon simply had too much padding, it wasn't downsized. The other app had a v14 version of the icons with less padding and I copied the normal versions not noticing the v14 directory.

Android App Icon not showing correctly on actionbar of different phones

Hi i have a problem with my app icon. The icon is displayed correctly on the actionBar of the Emulator but for some reasons it doesn't display normally on my device. Unfortunately I don't have another device models for testing.
Screenshots are attched below
To change the app icon I just changed the drawable on the manifest, is this correct ?
<activity
android:name="--ActivityName--"
android:icon="#drawable/navbarlogo"/>
EDIT:
I tried the app on different android version (Emulator). the result is good but not on the physical phone.
Can it be related to the ROM ? On the phone I have the MIUI ROM.
Checkout the size of your icon image. It should be small in size.
