Android as smartwatch - Android Q&A, Help & Troubleshooting

Hi, i have crazy idea in my mind. Can i make smartwatch of old android phone, everything what i need is just operating system for it(it has to be android), or something else what makes it like smartwatch. I think android wear is not possible (of course is? But you need drivers and kernels and so on) to flash onto phone. I love tinkering and this is the thing what i have been dreaming very long time

Android Phone as secondary display for another Android Phone

Hello,
As the summer-time appears, I'm about to mod my 4wheeler, and I just found one of my old Android Phones (Htc EVO3D).
I thought about methods to build in ,my Android phone in my 4Wheeler and use this as an Display for my android phone.
I'm thinking of a VNC-Server and a VNC-Client. But also I thought about all the smartwatches and Co.
In my opinion it should be doable to use one of those Android-Roms and port them to my Phone.
Did anyone of you thought about this, or know a other way to reach my goal ?
Maybee you can help me.

[Request] Wear Phone Switcher

Maybe someone can help, but Beelink use to work great until the latest update to Wear devices was released.
If anyone is like me, they would like to have there watch be able to switch between phones without having to do a factory reset on the device every time (I use an old phone for working out and not my everyday phone).
Can someone help and make an app, similar to beelink (which is unavailable now), that can bring this functionality?
That would be super handy with so many roms to try it socks having to pair the watch over and over.
I agree. Another reason why this would be awesome! Can anyone help???
Ya I'm seriously interested as well. Been changing roms so much this past week.
This is a way

New Android ROM Project for a Medical Device....

A team and I have been working on a medical product for the last year and we are figuring out the best way to deploy the project. We all have app building experience but none of us have ever built a ROM before, so we wanted to consult a forum of experienced Devs (you guys) to see if what we have in mind is actually feasible before we invest too much time/energy/resources on this particular path.
In short, the device is a wearable EKG machine that detects seizures, so far we have been able to successfully predict seizures in clinical trials and allow users 1-2 minutes of advanced warning. The EKG part and the algorithm are already working. What we are looking for now are phone calling, messaging, and bluetooth capabilities - which has us (at least me), looking to android.
First and foremost, we do believe that this system will save lives as early as the end of this next year, so any and all help will be greatly appreciated. We are finally coming down the homestretch and we just need a little help/guidance for getting us past the finish. So thank you again.
We want to create something that high risk seizure patients can wear on their arm . This will be an EKG machine and an android device rolled into one, the total size will be about the size of a credit card and about a half inch thick. My plan is to disassemble and strip an android device leaving only the board, battery, radio antenna, and Bluetooth antenna (no screen) and then combine that with the EKG machine.
The initial device that we choose is the LG-MS659 as it is small, lightweight, 2500 mah battery, LTE capable, and running Android Version 4.1.2 (more on that in a second)
So here are the questions we need answered.
1. Will Android work without the use of a screen from start to finish? We literally cant have dialogs anywhere that can prevent or pause the use of the system. We cant have fresh install screen prompts or the visual use of a custom recovery. So is it possible to load a CR, install the ROM, and use the ROM without any user interaction what so ever?
2. The reason we chose 4.1.2 is because once a device is plugged into a computer, there isnt an "allow this computer" dialog. Are there ways around this on Android, or is it just built into Android and we are correct in trying to use 4.1.2 instead? (4.1.2 was the last Android version before the hidden menu and the security prompt was introduced)
3. We would like to delete and uninstall all services and applications not relating to GPS, BT, and Network (Calling/Messaging) including the display drivers, and just run everything from the ADB shell prompt. How feasible is this?
4. Ideally we would like to make the system twice as battery efficient as the S5/S6 Ultra Power Saving Mode, giving us at least 14-21 days of battery time (Samsung claims 12-15). How feasible is this?
5. Where are we going to run into the most trouble?
6. What about this might not be viable?
7. If you were to building this, what would you do? We are primarily looking at Android as they are LTE/Bluetooth/Messaging/Call ready out of the box. They also come with a Li-ion battery and we can easily build apps that can utilize the aforementioned technology without starting from scratch or building our own libraries (no wheel inventing required).
Again, we really appreciate any help we can get on this matter - we are no experts, but we are hoping a few of you are.

Hey, happy New Years everyone.
I wanted to bump this as we are still looking for answers - If anyone can answer any of the above questions it would be greatly appreciated.
Thank You

There must be a way to get Android Wear on this

I've had my Gear S for about a month now, and I love everything about it, except for the software itself. Tizen is such a pain as I switched from my old urbane to this, and I'm actually kinda missing the urbanes functionality with android wear. Is there an updated method to install android wear on an SM-R750A. Please do tell

[mod] Wear OS on Fossil Q Explorist Gen 3 - Don't want Google

Hi all. First post here, but I have been reading a few thigs all over the place for some time and think this is a great place and resource, and every Android user should be directed this way. I'm not, however, a big fan of Google. I currently have an iPhone (don't hit me), but will be switching to an Android (as yet undecided which model, Sony XZ1C seems complicated for rooting due to DRM issues which I understand can be fixed now, OP 5T / 6) in the near future as the battery is not long for this world.
I got the above watch for Xmas, and I was wondering if there is a way of running it without the use of any Google services? A read around the wider web suggests that Asteroid OS can't be installed as it has no data out pins, but I have enabled developer options and there is an option to allow debugging over wifi. Can I therefore root the device over wifi and remove the need for the play store? There are a few standalone apps that would suffice for what I want to be able to use it for to be honest.
My biggest concern with rooting it over wifi is that it resets everything, loses the wifi connection and I then have no way to restabish the connection or send commands if it gets stuck somewhere. I think my wife might be a bit annoyed if I brick my Xmas present! I really do like this watch as well, a very nice looking watch that's a bit different to the offerings from the phone manufacturers.
Any thoughts on this greatly appreciated. Having looked around the web, I think I'll either be going for Sailfish or Lineage once I get an Android device.
Have a great day all and I'm looking forward to becoming more involved on these wider fora over the comings months.
All the watch and the OS is built around Google. This is not Android, WearOS communicates to the phone, tracks fitness, weather, manages battery and everything through Google Services.
And why would you remove them?
Sorry but even if you find the way to remove Google (by voiding warranty), the watch wouldn't work anymore as it should.
P.S. with WiFi debug you can only do debug, no root.
