[Beta][ROM] OXI - turn your smartphone into a computer (oneplus3/t nexus 5x and more)

[For moderators : As there is no "General" forum on the "Custom Roms" section, I hope I'm not wrong posting it here. Feel free to move it where it should be!]
Hi everyone!
I would like to present something we have been working on for some time now !
For those who thinks their smartphone can perform the same tasks that a computer can, we would like to allow you to replace your computer with your smartphone, using it on any screen, TV, projector. Basically, it's like Microsoft Continuum but better with Android

What is OXI ?​

We're developing a desktop-like environment for Android, implying multitasking, resizing, notification support.
You can use it directly on your main screen but the most interesting is to use a second screen (with MHL/DP or Miracast for instance) to get a desktop environment on it and still use your phone meanwhile.
It might be more clear with some videos : https://goo.gl/6R6rcZ

Our code is now based on LineageOS 14.1, and we're ready to follow the next Android evolutions. We're using LineageOS for compatibility reasons, because we want to be able to try with multiple phones without spending much time on porting.
We're currently in a buiding process, and you can already download the A.2.3 (Nougat) OXI versions for :
- OnePlus 3 / 3T
- OnePlus 2
- OnePlus One
- Huawei Nexus 6P
- LG Nexus 5X
- LG G5 (we have issues with DisplayPort, let us know how is it working for you)
- Samsung Galaxy S7 (Exynos - herolte)
- Samsung Galaxy S7 Edge (Exynos - hero2lte)
- Samsung Galaxy Tab S2 LTE (gts210ltexx)
- Samsung Galaxy Tab S2 wifi (gts210wifi)
- Lenovo Zuk Z1 (ham)
- Xiaomi Redmi Note 3 Pro (kenzo)
- LeEco Le Max 2 (x2)
- ZTE Axon 7

If you want OXI to be on your smartphone, tablet or other device, please tell us! If it's supported by LineageOS, it would be even easier for us .
To have a comfortable experience on OXI, you need to have a mid-range around (from experience, 40-50k score at Antutu is enough). But you need at least 2GB memory, 3GB is better. Basically : more RAM => more apps that can be opened simultaneously without slowing down the system. With 3GB, you can easily open 15 apps. We didn't had enough applications installed to crash our OnePlus 3 .

Usage​

I'm going to describe really quickly the basics of OXI. You'll find multiple apps preinstalled in the ROM :
OXI : Launch OXI on main display (phone)
OXI Remote : Launch OXI on the external display (Miracast, DisplayLink, DisplayPort, MHL, HDMI, Chromecast or other...)
For wireless, we recommand the Miracast adapters from Microsoft (Wireless Display v2) or from ActionTech. These adapters are fully compatible with OXI and eliminate completely the mouse lag that you might experience with other wireless adapters (such as Chromecast). Give us feedback, we didn't try everything !
OXI Control : A basic tool replacing keyboard and mouse. Two modes, "Keypad" is a simple touchpad/keyboard, moving the mouse from the phone, and the "Pad" mode is a mirrored touchscreen surface. Very cool to play multitouch games in OXI.
OXI Overscan tool : If you are using OXI on some TV you might notice a part of app missing. You can use this tool to crop the visible surface, adjust until you can see a red rectangle around the blue one.

How to launch an app in OXI :

How to connect in Miracast

Launch OXI on a second screen :

Control tool usage

Short-term

• Screenshot tool
• Full shutdown of the main screen when using OXI in remote (to save battery)
• Customization options (font size, background...)

Medium/long-term

• Inbuilt file manager
• Multiple instance launching (ex : two Word instances)
• Multiscreen support

Disclaimer​

• This is an alpha, quite stable but it's not 100% stable or secured.
• Installing it is your choice and we're not responsible for any damage or loss of data.
• However there's no difference between this and a CyanogenMod ROM for the installation, if you are confident all should be okay. We're using those devices for a long time now, and it works great.
• Never forget the golden rule : ALWAY SAVE YOUR DATA, and do nandroid backup before any operation on your phone.
• This is an alpha (again), so we might fix a lot of things between releases, so check regularly for updates

Installation procedure : It's like LineageOS 14.1 nightlies. You might find better tutorial for your particular phone here . Basically, the way to do is :
1. (If not done yet) : Unlock bootloader
2. (If not done yet) : Flash custom recovery (TWRP or cyanogenmod classic recovery), with fastboot, odin/heimdall, spflashtool...
3. (If not done yet) : In recovery, remember to do a backup !
4. Wipe all the phone (Might not be mandatory if you're already running LineageOS 14.1 nightly)
5. Install the zip file
6. (Optional) Install Google Apps (Open GApps, android 7.1)
7. Restart the phone

That might sounds stupid but with my brand new account on XDA, right now I can't post ROMs in each device forum... I will do that as soon as I can...

Known issues/Limitations​

- Chromecast is supported but won't have any optimization for the latency
- Google Play might be unstable on the desktop environment – the list of apps is not updated (will be fixed soon)
- Authorizing permissions might be difficult in some case. We advice that you also start your apps at least one on your phone screen before launching them in OXI
- You might experience some issues non-related to OXI, it might be related to CyanogenMod 13 :/
- Shortcuts on desktop are saved when exiting
- Bluetooth management inside OXI won't work (yet)
- Some applications (especially some games) won't resize properly. Unity-based games might crash if resized, we're working on it.
- Best experience is with 1920x1080 resolution on an external screen (TV or computer screen).
- Some TV screen won't report the correct real size, so the "size" inside the application might be larger than expected. We're working on allowing you to choose the dpi of each window
- Miracast is enabled up to 1920x1080 resolution and won't support 4K
- Only one instance of each application can be started on desktop mode.
- One application can be started on the phone OR on the screen but not both simultaneously.
- The overscan tool might need to be force-closed its overlay is shown above OXI.
- The ROM does NOT include any Google apps, so you should install them manually (We're usually using Open GApps).

FAQ​

- I'm an app developer and my app is not resizing correctly, why ?
-> That's a good question . Contact us and we'll see why !
- Are you using the Android Nougat multitasking/resizing ?
-> No, we are based on Android 6 Marshmallow. Our method is a bit different.
- Why do I need a special ROM for that?
-> We added and modified some parts of the Android system, to high and lower levels, to make OXI work.
- That's cool ! Can I use it everyday?
-> Sure, but keep in mind it's a beta right now, with stability and possibly security issues (still dev-code)
- Did you put any spy or anything ad inside the app or ROM?
-> No. Only love and required modifications for OXI to work. And for the app, we just added a crash-reporting library (Firebase).
- Can you make it compatible with [Phone/tablet model]?
-> We would like to make OXI available to the maximum of devices. Just keep in mind 2GB of memory is a minimum and 3GB is recommended. Let us know and we'll try to make it compatible if we can!
- Can you make it compatible with [application] that currently didn't work in OXI?
-> Give us information about the issue, we will investigate it asap.
- Can I install it with a multi-rom loader?
-> Probably... We actually haven't tried it yet. Let us know
- Who are you?
-> We're a small company called Auxens and we are in France (that's also why this text is probably full of mistakes, please put down the forks!). You can check our website, http://www.auxens.com

Very excited to see multiscreen support as a mid term goal.

Switching to Lineage OS could be a good thing. In particular Lineage OS x86 https://xdaforums.com/lineage/general/unofficial-linage-os-pc-based-android-t3531145
Would allow for PC with multiscreen - great for app developers and app research.

Can you help me compile a lineage is x86 version with OXI for display link external screen?

Does it work OK on 4k@60 displaylink DL6950 chipset(such as targus 160 dock)?

Hi !

I like the idea of having a vbox x86 OXI available for testing, we'll try to compile an OXI version on this platform
Then some test would be required but if the displaylink driver is enabled in the kernel, it should work for external screen (with USB bus capture by vbox).

For the 4k@60 we don't have this kind of hardware here, but if Android supports it, OXI should also work (backgrounds might be slightly pixelated due to their lower resolution). Best would be to ask DisplayLink if they tested the DL6950 chipset on Android devices. And with a android-x86/LineageOS based OXI, it will also depend of the GPU capabilities of the virtual driver.

Hi everyone! Sorry for the lack of news. We've been mega-busy after the MWC...
We've been working on a new UI, on the Nougat port (the confectionery was harder than expected ), on a Miracast fix for Nougat/LineageOS, on bugfixes and security improvements.
We will try to share soon some other CM13-based (with new UI) OXI rom, while we are still working on Nougat .

For Android X86-port, it's not done yet, but we're working on it too (would be also very useful for debugging).

So, we have been working hard, and finally we can provide you a beta version of OXI on several devices !
We're now based on LineageOS 14.1 (finally, nougat !) and we are currently building OXI with multiple devices. We'll add soon others devices officially supported by LineageOS.

The new version, A.2.3, is now available for Nexus 5X, OnePlus 3 & 3T (same package), OnePlus 2, OnePlus One, LG G5 (however we have issue with DisplayPort right know). Miracast should work.
You can watch new demos on our new youtube channel https://goo.gl/6R6rcZ and check our website https://getoxi.com which is the most up-to-date place to look up on OXI (but also our Facebook page and Twitter account )
