Can somebody please tell me whether it is possible to use the yotaphone 2's EPD as a (small) display to do some basic word processing outdoor out in the sun? I.e. to attach a keyboard/mouse to it (e.g. via bluetooth), to open some simple word processing app or even sthg like google docs, and then to just start working.
I have actually been looking for quite some time for some way to do this and I can't for the life of me understand why there aren't better solutions out there. I am always pleasantly surprised when I type notes on my Kindle Paperwhite. Of course it's a lot slower than on an LCD, but I am not a fast typer anyway, and I could live with some lag - if that's the price I'd have to pay to finally be able to work outside. I have thought of the Raspberry Pi x Kindle solution (but you can only type on sthg like vim); of ebook readers with an open OS that you can attach a keaboard/mouse to (like Onyx Boox that runs on Android 4.0 - and I'm still thinking about that); or of an e ink monitor (too expensive). But it is time for me to change phones, and if this works, I might actually consider it.
If anybody has any experiences or thoughts or - better yet - videos to share on this, I'd be very grateful... Thanks!

I haven't tried this personally, but I am fairly certain that this would work. Android supports bluetooth keyboards. The only limitation would be that you have to use mirrored mode, because there are no proper word processing apps made native for the EPD. Plus the system might not enable external keyboard for EPD apps only. Not sure on the latter though, I don't have any bluetooth keyboard/mouse to test this with.

Thanks Jeopardy. Can you (or anybody else) tell me whether there is an active developer community working on those EPD apps? And also - if you have to use mirrored mode, does this mean you have to open the phone and the AMOLED screen has to be 'on'? On can all of this just stay in the 'background'? And does mirroring to an additional lag beyond the usual - and much slower - e-ink refresh rate? If anybody has any first-hand experience with this, I'd really be curious... Thanks!

Well there are some developers, myself included, working on EPD applications. But not a lot. There should be more once Yota releases the device in USA around mid-August.
Mirrored mode does not need the color screen to be turned on. Of course behind the scenes it will wake up the system to similar state as if the AMOLED screen was on, but that's handled automatically. This means more battery use, but you should get a lot more out of it than using the color screen, especially on static apps like word processors which don't update often.
You can handle everything from the EPD. You can, for example, create a shortcut on the EPD for a word processing app, which will automatically enable mirroring and open that application. The lag on EPD when mirroring should be about the same as on native EPD applications, but of course you will notice it more because you can easily compare it to the non-laggy color side. There's only a few extra algorithms for turning the color image to nice greyscale, and some logic for creating additional "flashes" to fix ghosting when switching between apps etc. Should be fine for word processing, especially on external keyboard, provided you can write without constantly checking which letter you just pressed. The refresh rate on the EPD is about 8 frames per second, or one frame every 0.12s.
If you're seious about outdoor word processing may I suggest a rooted Nook Simple touch? It is small and light and a fraction of the price of a Yotaphone... as well as having a much bigger screen! You can pick these up for around 40GBP in good/new condition and although it will be a fair bit of messing around with rooting you are unlikely to come totally unstuck, and there is a lot of support on XDA to get you help if you do. With the NST device, you use the OTG USB mode to attach a bluetooth dongle, hard wired full sized keyboard or whatever to your desire. Pop over to the NST forum and there are many threads on this topic, but to whet your appetite here's someone who is doing that with a solar panel to power the setup!

Hi guys,
i tried many things to change the display resolution(to hd instead of fullhd), google'd a'lot ... but whenever i try to change the screen res with CM13, the phone restarts or doesn't apply the res.
the reason why i like to change is because of some heavy 3D games run much smoother (more fps, the phone becomes not hot, lower battery usage) which is working very good in TW roms.
If someone knows a method, or atleast a "per app resoluion change"(don't care about system UI res) please share your knowledge, thanks in advance
things i tried already:
'resolution changer'
'NoMONE' resolution changer
'Screen Shift'
result all in a phone reboot or bootloop
Update:
Ok, it did work over adb wm size, testing some things
Hi ,
I was wondering if it's possible to turn off the backscreen's dithering(not sure if that's the correct term) since it makes it look kind of soft. I know there is a CFG app on the forums but that's just for mirroring apps.
Cheers!
it's seems to be an "Anti-aliasing" like filtering.
i asked the same question as you in the CFG app thread but got no anwer so far.
if it's for reading, i now use fbreader as in this soft you can choose the filtering option an as it's a mirrored app you have the default EDP settings witch are more crisp than for the integrated reader
Same question for me...
I come from 1.87eu firmware and the images on the EPD was softer and less crisper
oh well, I guess my doge will have to deal with it
I have a Finow Q1 Pro running Android 6.0.1, and its display resolution is aproximatly 240*240. Google Assistant requires a minimum resolution of at least 720p so I can't use it on the smartwatch. I've tried some dpi and resolution changers but those didn't do the trick. Are the any other solutions? (maybe involving the Assistant API creating a non GUI app similar to this one?
Any suggestions would be apreciated
Hello guys, every time i take a photo, the image appears inverted or somewhere or when i'm playing a game like mobile legends, my screen rotates non-stop even slightly tilting the screen, it's a problem that i tried some solutions, such as:
Disable google photos, change rom with clean flash, change gallery, install other cameras and some other things, does anyone have a solution?
I'm currently on ion 2.9, firmware 11.0.1 global rom.
Thanks in advance for your attention =)
