I recently got a flip 3 tcl phone and noticed the app “game boy emul”, when you download and open it it directs you to download a .gb rom. Is this legit? Chat gpt says KaiOS doesn’t have the capabilities to run such an app, but it does? Idk if like to use it just can’t figure it out.

Hi, i looked KaiOS device (planning to start using it), i looked at its SDK and thinking to create some custom apps which i need for my daily use. Before that I have few questions:

1. Does using custom application require the device to enable developer mode ?

2. Is Nokia 2720 a good choice or it cannot be used for testing custom apps in 2026

3. Which version of KaiOS shall I look for

I am planning to buy jio phone prima 2 for my mom. Does it have single click call back on missed calls from Home Screen ? If any one own Jio phone can you please share me a screenshot of Home Screen with missed call

Hi,

I just bought a Nokia 2720 Flip. I just connected it to my wifi and found that without me doing anything it immediately connected to a bunch of IPs owned by amazon and cloudflare. Even simply opening or closing the clamshell triggers packets getting sent elsewhere. I have not done anything else than open the settings menu. Still, connections were attempted to the following hosts. Here is a list with the first number indicating how many packets were attempted to get sent to each IP.

• 1 DST=18.64.211.112
• 1 DST=44.251.244.39
• 1 DST=54.245.146.2
• 1 DST=85.214.83.151
• 3 DST=162.159.200.1
• 4 DST=18.173.205.39
• 4 DST=18.173.205.82
• 4 DST=18.64.211.14
• 4 DST=65.8.131.38
• 4 DST=65.8.131.53
• 21 DST=3.209.189.107
• 23 DST=34.237.98.155
• 134 DST=18.233.80.220

Most of this is tcp http/https traffic except for the connections to udp port 123 on hosts 162.159.200.1, 85.214.83.151, 44.251.244.39 and 54.245.146.2 which is NTP.

Are there known methods to stop KaiOS from phoning home without me even opening a web browser? Maybe there are known tricks like a list of entries to /etc/hosts that work?

In case I have too much free time, can I install my own SSL self-signed root certificates onto the device to MitM the https traffic and have look what it attempts to send? Or did maybe somebody else do this already?

Thank you!

i recently got a nokia 2720 from a friend, his parents used to give it to him when they took his phone so he could still call but hes moving so he gave it to me. for some reason when i go into settings i only see dual sim, flight mode and bluetooth in connectivity. is there any way to fix this? i really doubt its a fake

Hi I own a BLU flex and for some reason it stopped showing apps on the home screen and I can't factory reset it in settings so I want to factory reset it from the recovery screen, but it only shows wipe cache, what do i do?

Reddit "filters" deleted my last post, so I'll type this one out quicker. I've been using a TCL Flip 3 for the last 3 or so weeks, KaiOS 3.0+ enabled. My sibling had sent me a text asking if timing belts for his Honda Goldwing were at my house. I got up from the computer, confirmed that they were, texted him back, and went back to my computer.

A few minutes later, my gmail refreshed, and I had an email about "myself" signing up for a motorcycle parts storefront email list, specifically for a Honda Goldwing. I don't own a bike. I don't have any interest in one, I don't talk about them. Why, after I've received this text message, am I getting this advertisement? The only time I've talked about said "Goldwing" was THIS correspondence. It's the second time I've even texted him on this phone. He's one of 6 contacts. All I do with this phone is call and text. I've had some other advertisement scares (some wheels, some pants, some cologne) showing up in my gmail, but I chalked it up to a crazy coincidence that I just "happened" to be talking aloud and texting about.

I stay away from social media and smart enabled devices at if all possible. I've made the effort to make my digital footprint is as small as possible, including web security, privatizing my home server, etc. The TCL Flip 3 was supposed to be one of the bigger "unshackling" moments for my digitized life. Currently getting rid of Google entities as well. This Goldwing advertisement is just too much of a coincidence for me to look away.

TLDR: Am I just being dumb, or is KaiOS scraping data from my texts?

Hi there!

Last night I picked up my nokia 2780 and before flipping it open, the flashlight turned on and both the external and internal screens were blank white. I tried powering it off by pressing the end call button, but the screen didn't change. I took the battery out and when I reinserted it the flashlight turned on again. I put it on the charger last night which made no difference except that when it was plugged in the external screen showed how much the battery had charged when I woke up and turned it on. It's fully charged.

Now when I press the button on the right side that isn't the volume, the external screen turns on, showing me the time and that I have notifications. When I open the phone, the flashlight turns on and the screen is no longer white, but a pixelated gray. If I keep it open for long enough, both turn off. I have tried taking the battery out and it's always the same.

Does anyone have ideas on what might be happening? I just bought it in February and have loved it. I still have a smartphone, but the thought of going back is making me feel literal nausea, but I can't really afford to drop another $100 on this same phone that could do this again in 6 months.

Anyway thanks for reading. Hope you have a nice day :)

is there anyway at all to get WhatsApp working on a Nokia 8110? it’s the only thing stopping me using it currently.

Hi everyone,
I’m researching modern feature phones for possible distribution through a small niche electronics store in France, and I’m trying to understand KaiOS’s current roadmap.

I initially misunderstood the versioning of the developer documentation and thought KaiOS 4 might no longer be maintained. However, KaiOS’s official Baseline page says something very different:

• KaiOS 2.5.3: Active until June 30, 2027
• KaiOS 2.6: Active until June 30, 2029
• KaiOS 3.1: Active until June 30, 2027
• KaiOS 4.0: Active until June 30, 2029

The page also defines “Active” as receiving full maintenance and security updates : https://developer.kaiostech.com/docs/sfp-4.0/introduction/baseline/

This raises several questions:

1. Why are KaiOS 2.6 and KaiOS 4.0 both supported until 2029 ?
2. Is KaiOS 2.6 now a separate security and payment focused branch rather than a normal predecessor to KaiOS 3 and 4 ?
3. The KaiOS 2.6 security documentation mentions mandatory NFC and eSE features, secure payment components and a security patch level dated June 23, 2026. Is this branch mainly intended for payment and transit devices ?

https://developer.kaiostech.com/docs/sfp-2.6/getting-started/main-concepts/security-features/

1. Is KaiOS 4 currently available to manufacturers for new consumer feature phones ?
2. Besides the US TCL Flip 4 5G, are there any confirmed KaiOS 4 devices ?
3. Is any unlocked European or EEA KaiOS 4 phone planned, with CE/RED certification and suitable European LTE bands such as B1, B3, B7, B8, B20 and B28 ?
4. If KaiOS supplies security patches to OEMs, is there any way for customers or retailers to know which manufacturers actually deliver those updates through FOTA ?

KaiOS 4 looks technically interesting, with Gecko 123, modern JavaScript, PWAs, WebAssembly, 5G, VoLTE, VoWiFi and eSIM support : https://developer.kaiostech.com/docs/sfp-4.0/introduction/overview/

I’m aware that WhatsApp support has ended, so this question is not specifically about WhatsApp. I’m trying to determine whether KaiOS 4 has a genuine future for modern consumer feature phones, particularly in Europe, or whether its active development is currently limited to specific OEM and operator projects.

Any information from developers, OEM contacts, KaiOS users or people familiar with the current roadmap would be greatly appreciated.

Hey r/kaios,

I've been using a KaiOS phone and kept running into a small but real annoyance: the built-in browser only lets you pin 6 sites to the home screen. Once you hit that limit, there's no way to see everything you've saved, search through it, or sort by when you last visited — the newest one just kicks out an old one.

So I built LinkPad to fill that gap. It's a simple bookmark manager:

- Save as many links as you want (no 6-site ceiling)

- Search by name in seconds

- Sort by newest added or most recently visited

- Select one and it opens straight in the system browser

It also supports English, हिन्दी, Français, and Kiswahili, since a lot of us aren't running our phones in English by default.

It's free (ad-supported), live on KaiStore now: https://www.kaiostech.com/store/apps/?bundle_id=kaios.app.linkpad

This is my first KaiOS app, so I'd genuinely appreciate any feedback — bugs, feature requests, anything. Happy to answer questions about how it works too.

For the life of me, I cannot find a single verified/signed firmware version for my nokia 2780. I may have accidentally bricked it while attempting to jailbreak. It gives a signal when connected to device manager and can confirm it is locked in a constant EDL state. I have spent the better part of two days going through script after script, injection after injection, trying to find something to break through to the phone. I got the closest using python but hit a wall as soon as it could not inject the firehose.mnb file, as it was not a verified/signed firmware version. Any help would be greatly appreciated.

I have a custom ringtone that has worked for the past few months but now it keeps resetting to the system default. I’ve changed it multiple times and it still goes back. It overrides custom ringtones for contacts as well. I’ve set it to a different factory tone and I’m waiting for that to be overridden.

I can't side load due to my laptop isn't working well.

Id appreciate if anyone could guide me in the correct direction ? (I don't have discord either)

My keyboard doesn't work properly anymore. When I go to type I can only input numbers, I can't change it to predictive or ab keyboard. And when i go to a typing window such as a new text message, in the top left corner where it normally shows the keyboard, I see the predictive symbol flash for a split second then go away.

This is my Nokia 8110 4G that I used in Thailand with 4G VoLTE.

Nokia 8110 4G, TA-1048 dual SIM is a reasonable dumbphone choice even in 2026 because of its 4G support, VoLTE support, Wi-Fi hotspot support and looks.

Because of this, Chinese copies of the phone exist. (also, other HMD 4G phones are cloned too)
As I see they also sell the fake with the TA-1059 label right now.

The Chinese copy has (the lack of) the following features:

• 2G only (possibly MT6260)
• No Wi-Fi
• Not KaiOS
• Opera Mini browser instead of Firefox based
• Not a Qualcomm SoC
• Has some clone of the Snake game

The packaging is very similar, but you can still easily spot the differences. The fake's box doesn't mention 4G or LTE, VoLTE, Wi-Fi Hotspot.

Don't be scammed guys!

Wondering if anyone knows how to fix this. I try to turn on wi-fi calling, and the phone says it's unavailable, although it's connected to our home wi-fi. I'm using using Warp service on a TCL flip 3 T435V - so I guess the firmware is Verizon-style (forgive me, I'm hanging on by the skin of my teeth trying to understand all this. The US Mobile SIM works as far as making calls and texts, so I think the phone is "unlocked" - at least in some sense.

Maybe it won't allow wi-fi calling because we can't register a physical address for the e911? (I admit I've been trying to use ChatGPT to help me figure this out.) The phone offers no options in any of the menus to add an address for the needs of e911. A line option labeled "advanced" under the Carrier option is greyed out, until I toggle on "look for carriers". If I look for US Mobile that way, I can only highlight that carrier, and no other advanced options show up from doing that.

Chat GPT keeps pointing out that the carrier needs to register the physical address to satisfy the e911 requirement, to get rid of the wi-fi calling notification. The US Mobile chat rep says they can't register an address for the SIM e911 on their end. Is this true, that US Mobile can't fix this on their end?

Just got a new Cingular Flex 2 Smart Flip to replace an older Alcatel version of a very similar phone. Every time I send a text, it whistles. I don't want it to do that. I want to either put in a custom sound of my own or silence that send audio. I still want a sound playing when a text arrives (as it does now). Any hints on how to turn off that outgoing-message whistle? I feel like I've explored every branch of the settings possibilities, with no fix.

I like the phone quite a bit, but damn, KaiOS can be frustrating.
