the two other older threads on this came up empty.
Is there a way to use an Android device as a second display for another Android App? (ideally via BT)...
The idea is that a special app could draw/display on the second screen also.
Ideally the second display device would be either iPAD or Android or varying sizes..

Since Android 4.2, Google added Secondary Screen display APIs. Typically they are used to mirror an android device to a TV. There seem to be some for android to android though. I'm not familiar with this personally, having never had reason to do so, but this app https://play.google.com/store/apps/details?id=com.awindinc.sphone2tv might be close to what you are looking for?
This device caught my eye recently (Kyocera KY-01L):
https://uncrate.com/kyocera-ky-01l-card-phone/
Points of interest:
* Android-based
* e-paper display
* ultra compact
Personally I feel Kyocera made a huge mistake by not including the Play Store, or at least including an e-Reader application. A pocket-sized e-Reader that is also my phone just sounds awesome in theory (although the 380mAh battery might prove otherwise in reality...)
Since I use Hangouts and Hangouts Dialer for all my communications, I can't really use this unless I can get gApps installed.
Does anyone have experience hacking Kyocera phones? How difficult would it be to get root, TWRP, and gApps working on this thing?
I googled that phone and found your post. Most intriguing idea, but overpriced imho. I would like to test my developer skills on that but without adb or at least apk installer its useless
Android is not fully compatible (out-of-the-box) with e-ink and screen sizes under 3", unless it's heavily modified. Which is not worth the investmet, considering the target market. And even if Android were adapted, many apps wouldn't run anyway. They wrapped a layer around it to run essentials services. Note that there is a real browser though.
KY-01L Information
So i bought one of these myself out of curiosity and here's what i've found:
ADB can be enabled from the phones settings (the option is called "switch usb debugging") once it's enabled you can sideload APK's
APK's cannot be installed on the phone itself, when doing so you get the message than unknown sources are not enabled however as kyocera have modified the security settings there is no way to enable this afaik
The apps use AOSP icons and have some normal screens present which can be accessed with an activity launcher
When using installed apps the E-ink screen switches to a high refresh rate mode at random and the only way to get it back to normal is to launch cardphonehome (the default launcher)
The phone won't connect to any UK networks (i've only tried vodaphone and EE sims in it)
Bluetooth media audio seems to be removed entirely, even when sideloading a music player
The stock keyboard uses a 9 key input for text, you can sideload something like gboard but i haven't found the option to set it as the default input method
If you intend to buy one then i would suggest looking on YAJ proxy sites like buyee as they tend to go for ~£160.
Apps i'd recommend sideloading:
Activity launcher - lets you get into hidden menus and back into the stock launcher
Stealth music player - Plays music through the phones earpiece, can also enable the earpiece for use with audio from other apps
i'd also suggest lowering the DPI as some apps may be cramped
Dialer codes
*#*#4636#*#* - Android Testing menu
*#*#3878#*#* - Qualcomm FTM menu
*#*#225#*#* - Calendar info
Update: i've noticed the soc that CPUZ is reporting conflicts what others have said, ADB's CPU info command reports it as a wear 2100
I'm really curious if/how an ebook reading app would work on this. Did you try that out?
I'm considering buying a used one to try out as an ultra portable ebook reader.

I tried the kindle app, Whenever it's opened it spams an error saying something about not being able to download image files for a few minutes, after that it works fine.
Phone density is set to 210 and kindle text size is on default

Amazing. Thank you so much Harry, this is great. I'm going to give my experiment a go!
any idea how to make it connect to EU 3g/4g ?
I have the Light Phone 2 which is very similar. I was able to root it and sideload apps on it. Harry is it possible to send over APKs from your Kyocera Card phone so I can test them on the light phone?

You can try, i used apkextractor to extract them but they won't install on another device and trying to install them on the card phone itself gives an error saying the package is corrupt

Hi
First of all, I appreciate the above information where I could find customizing about KY-01L. I was able to install Gmail, Chrome, Line lite, Gboard, and other utilities into my KY-01L!
To be honest, it was quite a stressful process to load apk`s and configure them a number of times.
The first step, I installed the Square Home launcher (https://play.google.com/store/apps/details?id=com.ss.squarehome2&hl=en&gl=us) and the Quickshortcut maker (https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut&hl=en&gl=us) that I am able to configure 10 times easier (Maybe some similar types of the app should work). the default setting of KY-01L is not able to configure app by the screen that is how it is designed by Kyocera.
After setting those 2 apps, I can configure launcher/shortcut in the home menu.
My KY-01L is not stable yet... still need to minor adjustments of configuration but it works what I was expected.

Hi there,
Can you explain how you managed to connect it to the network? The one I have is SIM unlocked, I can see available networks but it won't connect. The X.... symbol is displayed in the status bar ("Out of service area") but I am quite sure that the frequencies match.

Hi
I am using NTT Docomo carrier (in Japan) which is the preferred carrier for the KY-01L. KY-01L has limited bandwidth using LTE bands of 2.0GHz and 800MHz only. You would better check with your SIM carrier that uses those bandwidths or not.

Thanks for replying!
Well, it seems that my carrier doesn't offer the exact same frequencies. 3G is at 2100 MHz (B1) and LTE is at 2100 MHz (B1) and 1800 MHz (B3).
Too limited, indeed. I've been using Docomo and SoftBank and AU phones for over fifteen years now and they all worked but not this one

Hi I just ordered my KY-01L off ebay, and looking forward to doing what you're doing!
My question is - after you installed all these things (Square Home Launcher, Quick shortcut maker, Gmail, Chrome, Line lite, Gboard and other utilities), does the battery drain faster even when idle? If so, how much faster vs the vanilla version.
And what other utilities were you able to install on the KY-01L? Music player? Kindle? Youtube? Just curious to see what works...
Lastly, was the Square Home Launcher the only launcher that works? Or there were others that work but this is your preference.
Thanks!
Hi
What are the problems/ issues of using an old version if the phone is only used for calls/ texting/ email (not GMail)? After rooting a device and removing Bloatware and Google what's the potential issues in using the device? I only use my phone for calling and texting and keeping notes, some photos, few emails. No banking/ shopping apps, no social media. I like having a very basic phone, so most of the upgrades in the UI would probably not be important to me. I plan to upgrade at some point but I need to have a phone with a 4" or smaller display and it's got to be around $50 used.
I have a couple of older Samsungs that are small, which I prefer. One is running 4.4.2, is rooted and is in the process of removing most Google apps ( I have installed the Brave browser but limited data use) and the other is even older running Gingerbread that I plan to re-purpose for a signal generator but might consider using as backup.
New to Android and still learning, so any advice is appreciated.
Thanks
PS. I was planning on moving to Lineage but I managed to buy a Samsung with an unlockable bootloader so just rooted it and started removing stuff I don't need. Seems to be OK for the most part.

Hello,
there might be some downsides, one of them being that your device doesn't have the latest security patches implemented. Another one is that some apps might not work anymore as their minimum API version is higher than your current OS.
Beside this, there are no real downsides of running an older Android version. If you got your device setup according to your needs, then there is no real issue at all in case you don't store any sensitive information (bank account username/password for example, but this applies to all mobile devices in my opinion) on your device.
Hi! I have a LG Exalt 4 (LGVN220), It's a 4G Flip phone running off of android. Officially it doesn't allow you to install apps unless it's signed by LG, but if you rename the package to com.android.cts."packagename" it allows it to install. The problem is when you try to use the app it doesn't either detect or allow you to use the regular physical keyboard, does anyone know how you can change the code (maybe in the android manifest...) so that it uses the physical keypad and not touchscreen (since the flip phone doesntn't have a touchscreen, only a keypad)?
hi i was thinking about buying this phone for my dad and would like to install apps. did you have any success with this?
Not going to work.
notice not all apps have this prob. mostly apps built on cross platform engine like xamarin etc have this prob, but if app was developed in android studio it definitely works . unfortunately, your only way around this is to rewrite the app in android specific ide... good luck
Hi everybody,
I switched back to Sony and got myself a Xperia 1.
A few years back, when I had a Z2 and a Z3 I was a huge fan of the performance and the launcher and Sony add-ons.
Unfortunately Sony decided to go towards stock Android-ish (a bit too much in that direction).
What I am missing severely is:
1. to make a scrolling screenshot and then editing it with a pen or my finger to comment or whatever. Like any Samsung, LG, Huawei, xiaomi etc does.
Is there any way to do that on the Xperia 1?
Or is there an app you can recommend, that does not come with adverts and respects privacy?
2. I am missing to switch off network connection for apps seperately (like one plus allows)
3. A functionality to clone apps (like any chinese phone does). Having a dual Sim phone this is really mandatory in my point of view.
At the moment I use island and app cloner, but they both have their limits.
Thanks a lot for any help and suggestions.
Joe
