[Android Q&A, Help & Troubleshooting] AxelTerizaki:
Hello.

I apologize in advance if this is not the right forum to post in, or if it's not the right site at all, but a friend whose specialty is Android led me here, and told me to post my problems here.

I am a long-time iOS user. But I am also disabled : I have 1/20th vision on my left eye and nothing on the right one. My eyes are easily blinded by light, and as such I find it painful to read text on a screen when it's black on a white background. In Windows, for instance, I change the Windows theme back to Classic Windows so I can edit the different colors that make windows, buttons, and menus so they are easier on my eyes. In OSX, I use the 'Invert Video' feature on a shortcut key, so that when I press it, the screen suddenly inverts all colors, makign it much easier on my eyes. (Sadly, it also inverts colors on pictures, but that's okay, I can live with switching back and forth if needed.) On Chrome (any OS), I use the Stylish extension to force every site's CSS to follow my own and keep backgrounds dark and text light... You get the idea. On iOS, a similar feature to the one in OSX exists, and you have to press the home button three times to switch it on or off.

If I'm posting on this forum, this is because I have questions regarding Android's features for disabled people like me.

From my understanding, and from what I briefly tried on my sister's Acer E330 (Android 4.0.4) there is no such feature. A friend with a Nexus 4 confirmed this too.

I was wondering if there was some kind of plugin, addon, extension, app or whatever that would allow me to redefine Android's interface (a theme perhaps?) or even better, some kind of 'Invert Video' feature just like on iOS. I'm asking about this because I'm considering buying a Android device since I realized I was starting to have problems with some displays used on recent iPhones, iPads, Macbooks or even on regular PC laptops like MSIs' or Samsungs'.

The problem I have has been unresolved so far as there is no way to tell what part/setting of recet LCD/LED displays make my eyes sore after about 5 minutes of use. I did a lot of research without being able to find out what caused this exactly, but a lot of people seem to have the same kind of problem while having a normal eyesight unlike I do.

So, right now, two things prevent me from being sure if I should buy a Android phone or not :

- I need to make sure the display is fine with my eyes.

- And the reason why I'm posting this here, is that I want to know if it's possible to have the same kind of feature on iOS/OSX for changing colors of the whole screen by the press of a physical button on the device several times (this seems like the best solution, as a system setting switch would be a bit painful to use. FYI I really overuse and abuse this feature because it allows me to quickly switch to a dark background on white pages, while restoring the normal colors if the next page I'm visiting has a black background.)

So there it is, again, I apologize if that wasn't the right forum or anything. I hope someone here can help me with this problem. I'm not a die-hard Apple fanboy : I just happen to use their devices because they are the simplest to work with considering my disability.

Thanks in advance.
