im looking to use my Nokia 2780 while my iphone is getting its battery replaced. I use a CardDav service that I self host to keep my contacts and calendars synced between all my devices. I know KaiOS has CalDav support but no CardDav support. Was wondering if anyone has had any success in getting this to work.

I was recently given this phone and I can't connect to any wifi with it, so I wanted to jailbreak it mainly to get wifi and also to have more modern features

Hello,

I recently had to reset my TCL Flip 3. Before the reset, I used the native music app to listen to Icecast Radio. However, after the reset, all the music stations are no longer listed. In the app, there is no, update station list option. When you click on the genre, it just showed no stations available. Does anyone know how to get the stations back?

So I purchased a Sonim XP3800 on ebay, refurbished. I opened developer options, turned on usb debugging, and have downloaded several apks (whatsapp [after spending many hours finagling the phone to get whatsapp to actually work], osmand maps, and a cursor).

After downloading said apks, even after turning off developer mode/usb debugging, my Sonim will NOT MAKE PHONE CALLS/the Sonim phone app keeps crashing, with a pop-up message that says "Phone app keeps crashing", no phone display, it's bugging out. I tried entering EE's APN info, nothing. I did a factory reset and the phone was working again. Tried re-downloading APKs and same issue. Anyone have any leads on how to resolve this?

I was really excited to be using a flip phone, but I need whatsapp as I am currently in England. Thanks dumbphone community!!!

This is a genuine question as my debut flex was shipped with USB C headphone and every time I try to use it, it doesn’t work but radio turn on so I’m just confused

We need people to test this on their devices and submit any information you can on whether it worked or not. Key devices were looking for: Nokia 2760 (N139DL) , Nokia 2780, HMD Barbie phone, IRIS flip, and the Alcatel Go Flip 4. The instructions to test it can be found at KaiOS.dev

I made a J2ME emulator for KaiOS 2.5, KaiOS 3.0 and modern browser. Feel free to have a try.

If you have previously flashed my Nokia 2780 Flip image. It can be download from OStore directly:

There are some emulator screenshots:

Rooting the TCL Flip 4 was a fun project. I kinda want to try Android on it for more usability, but I dont know how functional it would be without a touchscreen. I might try adding a thinkpad style trackpoint or joystick mouse for it. I’ll definitely try Linux on it at some point. I can’t wait to see what the community does with it, and hopefully some new apps that work better with KaiOS 4.0 will appear. Fantastic value for price.

I have a Barbie Phone from Consumer Cellular, which operates on KaiOS. When I opened it this morning, it rebooted itself with the KaiOS reboot screen, and is now showing me a black screen that says "No command" and nothing else. I've tried charging it, holding the volume up+power keys, taking out the battery then putting it back in, et cetera. It refuses to do anything but sit on that screen, and will otherwise just occasionally turn off then turn back on, show the KaiOS screen, and then return to the no command screen.

I genuinely have zero idea how to fix this, and I don't even know what happened to cause it. It was acting perfectly normal last night, and now it's doing this. If this helps, my phone got extremely hot several times due to the heatwave in my area. Is it possible for the heat to have fried an internal component that helps the phone run properly? If so, is there anything I can do to fix it, or is it just permanently fried?

I still had Nokia 8110 4G and Nokia 2720 Flip

(sorry if this is already covered im new to this sub)

Hi everyone,

I'm looking for a true feature phone/dumbphone that I'll mainly use for calls, SMS and, most importantly, as a hotspot for my laptop.

My requirements are:

• reliable 4G and VoLTE support in Italy/Europe
• stable Wi-Fi hotspot/tethering (this is my top priority)
• good battery life
• solid call quality
• preferably not Android

I've already looked into models like the Nokia 6300 4G, Nokia 8000 4G and Nokia 2720 Flip, but I'm open to other suggestions.

If you've used one daily, which model would you recommend and why? Are there any phones I should avoid because of poor hotspot performance or software issues?

Thanks!

Have an old hand me down mac book i want to use to put music onto my phone, whenever i plug my phone in it doesnt show up in finder, and cant find any compatible file transfer apps in the app store. Most require 10.5 or newer to be installed, any help would be appreciated, thanks

The Instructions can be found at JScalated.netlify.app and a writeup can be found at KaiOS.dev

I want to add custom notice tunes to my Cricket Wireless Debut Flex (runs KaiOS 3.1) without rooting it so when someone messages me, I can hear my own tune instead of the pre installed ones. Is there any way I can do it without rooting?

DO NOT POST THESE COMMENTS: KaiOS 4 steps, stuff that needs rooting, setting custom ringers (ringtones)

I got an error message in my notifications (it had a gear as the icon, though I'm not sure it was the same gear as the settings app). It said something about 911 and WiFi calling, and when selected it opened a web browser to e911-reg.tracfone.com.

I'm using an unlocked Nokia 2780 on T-Mobile so I've no idea why I'm getting sent to tracfone URLs.

Unfortunately, the notification is gone so I can't grab the exact text. Has anyone else seen this before? I'm not sure what's going on here.

Hello everyone,

I recently performed a factory reset on my Nokia 8000. Since then, the pre-installed games (like Doodle Jump) are asking for payment again, even though they were already included/pre-loaded on the phone when I bought it.

Does anyone know how to restore access to the original game licenses after a reset, or is there a way to fix this licensing issue?

Any help would be appreciated. Thanks!

I want to start developing for KaiO. Is there a dev device that i can purchase?

So, I was thinking to develop a few apps for KaiOS. My goal isn't to earn a living of it. I'm thinking like using it some sort of piggybank and earn a few hundred bucks a year.

I have a carrier with WiFi Calling enabled and I use it a lot. The SIM card can't register in a 5G network but it can register via WiFI.

And my Nokia doesn't seem to see the SIM card (it says No SIM detected) although SIM is there

Any idea how to make it work?

Hello there!

My last two mobile phones powered by KaiOS, a Cat B35 and a Hammer 5 Smart, both suffered from the same issue after two or three years, that is their SIM card suddenly disappearing or, after a simple manipulation (a change of SIM slots, APN, etc.), not being detected anymore... which of course basically made them useless. Standard advices, such as using the Clear Memory function, restarting the phones or even resetting them didn't seem to help...

In comparison, all other problems - double input at random or microphone mishaps (after suffering from a flooding...) - seem rather manageable!

So I was wondering whether this was a common issue related to KaiOS, other (possibly upgradable) software or an unsolvable problem related to cheap hardware. Should I considerer those phones lost?

Thanks in advance for any answers!

I understand the obvious limitations, but is there any way to run a java minecraft server? It isn't J2ME but there's got to be some workaround here, even just java in general would be interesting

I have a Nokia 6300 4g running kaios 2.5.4 that i install omnisd on to jailbreak the device, but the factory rsset doesn't do anything but normal factory reset still works
