Hey guys sorry for the one week absence and lack of updates. I've been incredible busy with sort-of-finals and work. I'm working on a big big update for Exo UI Dark, building it from the ground up again so I can eliminate a lot of bugs while also optimizing it a bit. I will also take out a couple of apps that have most colors hardcoded or linked (Don't worry, it will only be 1-3 apps tops).

The reason I'm doing this is because those themed apps look almost nothing like how Exo UI should initially look. Also because Quality ≠ Quantity. I know, I know the more apps the better, but it just doesn't look great at all. A lot of you have also been asking when I'll implement Google+, I've been working on that for the longest time. Google+ is a massive app, so much linked colors, right now the version that's on my phone looks like Holi (lol), its just, nah. But I'm trying my best to include it as soon as possible.

Exo UI Dark will also get a fourth color option for Arcus when it's released. I can't say when I'll update, but hopefully by the end of this week as I really want to get this update out to you guys.

I have also not forgotten about Exo UI L, it will get the usual bug fixes, some more themed apps, including (probably the first ever) white Spotify! :)

Stay tuned!

The 1.4 update's bringing Arcus support with the same two styles Exo UI Dark has gotten a while ago. I'll be adding more and more styles as time goes by. Join the theme community if you're experiencing bugs here -

Style Debug

I'm one of those people who dig really deep into android styles and modify them and that usually results in bugs that I don't exactly know how to fix or what's affected exactly. So I made myself an app that pretty much tells me in detail what I have themed and what the name of that is. Since it's been extremely useful for me, I've decided to share it on play and throw in some additional components. You have two themes to debug from - Theme.Material and Theme.Material.Light

Essentially what this does is it's similar to the Theme Debugger on the play store, however I found that it's useful in showing me what's themed but not telling me where I can find whatever I've themed or the exactly name of the style. With this, I can be even preciser in changing my styles, well that's just me.

(This is not a theme)

I'm going to stop updating every day or every second day, so because of that the next update for Exo UI Dark & Light will be on Sunday which will both be big updates. I want to accumulate a lot of bugs and make big updates vs small ones. The following apps have been requested and will be included (if possible):

- Spotify (accent colors only)
- Google Chrome dev & beta
- Apple Music (if possible)
- Facebook Slim (Facebook client) (if possible)
- AOSP / CM Messenger
- YouTube (Header & Accents only)
- Stock Calculator
- Twitter (if possible)

(if possible) meaning, I haven't checked it out further enough to know whether most things are hardcoded / linked. If they're not, I'll theme the whole thing. If they are it'll probably be accents only (they almost never hardcode accents. Accents meaning e.g the blue in twitter or the red in apple music)

& of course most bug reports reported here.

So if you have any more bugs, please post them before Sunday. So I can include them as well as the next release will be the following Sunday (unless there are critical reports such as everything going crazy).

I have this weird bug where the battery color is isn't white. Anybody know why this might be happening? All my battery related colors in systemui are white.

Status bar icon tint, your color for the status bar triggered the tint on the battery. It's built in M. There are values in colors.xml to change them. I haven't changed it but I see the colors. Systemui dark_mode_icon_color... light_mode_icon_color...
