Paranoid Android's PIE Navigation System Is Almost Out Of The Oven


Recommended Posts

All pastry jokes aside, PIE is a fully-customizable replacement for the stock on-screen navigation buttons found in more recent versions of Android. It stays hidden off-screen, only to be brought to life by a predefined gesture. PIE can be manifested on all four sides of the devices, and there's even an option to set up multiple trigger areas, making this not only a neat mod to look at, but a convenient one, too.

Of course, long-time Paranoid Android users are probably shouting "Hey, this isn't new!" ? which is completely true. This has been a feature in the ROM for some time, but it's now reaching its final stages of development. Where there used to be lag, you'll only find smooth transitions and blazing speeds. The dev team re-wrote the navigation code from scratch (as opposed to simply modifying the AOSP code, like in the past) to ensure a buttery smooth experience. Judging by that video, I'd say they achieved that goal. Of course, they're not completely finished yet, so there are still a few bugs to work out.

PIE isn't just about a new navigation experience, either ? it also offers customizable colors, status information (like clock, date, et cetera), notifications, and toggles. One nice thing about PIE is that it's dynamic, meaning its size will be defined by the device's dpi; in other words, you won't see a stretched phone UI on a tablet.

According to PA's post on Google+ highlighting this feature, updated builds of the ROM with this freshly-baked PIE should start rolling out as early as tonight. You can head here, as well as Paranoid Android's site, for more information.

Been using PA's PIE since Alpha stage. What can I say? Completely reclaimed all screen space and getting better and better each day. The BEST 3rd party ROM I've used. Yes, better than CM and AOKP (tried both, too).

Looks like a ton of swiping and constant finger contact with the screen. Using this with one hand could be troublesome, I would think single contact clicks would be more efficient. If your finger loses contact with the screen you have to swipe and start over in this usage.

:( Too bad I can't run this piece of my ancient phone. They have a version for it, but nothing nearly as pretty. :) (HTC Hero CMDA).

Watching the dev scene on these though has given me enough ideas to last a while once I get my new Droid later on this year. :woot:

Actually it is completely fine with one hand. You can choose the size of the pie, the location of the pie, and the animation speed of the pie.

Do you lose contact with the screen when you swiping left/right? No? Then you won't with the pie navigation because the swiping distance is SHORTER than swiping screen.

If you really don't like it, you can disable it. It's all about choices.

It's a custom ROM. So yes you need to unlock and flash through CWM/TWRP.

no i meant the PIE feature is available for download to install on any ROM you do not need Paranoid Android to use it. I currently have it running on CM10.1

Haven't realize this PA ROM feature is an app. I haven't heard the PA team said that.

suffers from the same problem as ubuntu os on the phone. hidden menus work fine on a computer with a mouse. but on a phone not so much. sure it can make the phone look cool and neat, but usability it's terrible.

first you need to swipe/gesture to get the menu out, then you need to hold your finger there while aiming for the right option. and because you need to hold all the time to start with, you lose the ability for further options by long hold, though that's fairly minor.

it just makes more sense to have those option the pie menu offers available all the time on the dock instead. faster and more convenient.

The Program is called LMT Launcher, even though its not a launcher. you can find it here

I've been using the pie menu that can be enabled through labs in the stock Android browser, and while it takes some time to get used to it it's quite comfortable to have all the options within the reach of my thumb while holding the phone with one hand.

I'm not sure about this PA pie, though. It's just three buttons, I've no problem with their placement on stock Android.

context long click "pie" menus actually make sense on touch devices and even some mouse interfaces as well.

Wow, I never knew this got ported to Android. This app was probably the only thing I missed when I ditched WinMo for Android on my old HD2. It didn't have the pie feature back then, though (just the gestures).

Just know that the LMT launcher cherry picked PA's PIE interface code from the past few weeks, not the other way around as many users claiming.

I feel like I need to try this out, for sure, but it doesn't look very... useful? Maybe practical is a better word. And you reclaim screen space from what, the tiny status bar at the top that's useful to have showing at all times? The status bar is the one item that stays on the screen at any time and lets you see important info like time, signal, and battery. These all seem like the kind of things that I WANT to see.

Don't get me wrong, it definitely looks cool, and maybe it works better than I'm picturing it. I certainly don't have a problem with innovation in the phone UI field though. This is one of the most unique UI's I've seen yet.

It has the choice of hiding only the Nav bar and keep the status bar. Remember it's still a WIP.

    • Why Delta Chat is the best decentralized messenger you have probably never tried by Paul Hill There is no shortage of messaging apps out there; we have WhatsApp, Messenger, and Telegram, just to name a few. While Meta has taken steps to incorporate encryption into Messenger and WhatsApp, they still leave a lot to be desired. If you are in the market for a messaging app that promotes security, privacy, and optional anonymity, you'll want to read what I have to say about Delta Chat. For those not familiar with Delta Chat, rather than relying on centralized servers as you do with Facebook Messenger, it relies on email. Essentially, it is a chat interface that feels like a messaging app, but secretly in the background, it is firing off emails. In the past, you used to have to sign in with your email account. When you sent messages to people, it would just be sending encrypted messages to their inbox, which their Delta Chat client would decrypt. When I first learned about Delta Chat, it required users to sign in with an email account, but I was pleasantly surprised upon trying it in 2026 that this is no longer a requirement, or the preferred method was to use the app. Recently, I’ve tried UAD-ng on my old Nokia 3.4 to disable most of the Google apps because the bootloader is locked, and this is the next best option. While finding replacement apps in F-Droid, I came across Delta Chat again, and it has undergone quite a big change since I last used it, with its new chatmail relays, which no longer require you to sign in to your own email account, providing anonymity, and they offer greater security. Android and Desktop Delta Chat apps. Not only does it run on my de-googled phone, but it also works on desktop computers and iOS, making it truly ubiquitous. For me, Delta Chat is a wonderful alternative messenger because it gives you more control. It supports switching between different profiles, which you can set up super quickly; you don’t register a username, you don’t register a password. The only thing you do have is a random string email address on a chatmail relay (which you don’t have to memorize). To maintain access to your profile, you just need to add a second device to your account via QR code or make a backup of your account, which you can restore later. Fail to do these, your account is gone - as it should be if you don’t want to leave accounts that could get hacked later on. My decision to block Google stuff on my Nokia was done for practical reasons; the device sucked when it launched, and it sucks even more now. The nice thing about F-Droid and the apps within is that they’re usually lightweight, free of bloat, and work well on that device. What was inconvenient for me was that it was hard to send messages from that device, say if I wanted to copy a code over to my main phone or send family members a link from that device. That’s when I decided to look at the available chat apps and saw Delta Chat. Another nice thing about Delta Chat is its notifications. Some messaging apps rely on Google’s ecosystem for notification transport on Android; however, with Delta Chat, it can use Google’s solutions if you have Play Services or MicroG installed. Otherwise, it is able to keep a background connection to the chatmail relay server so that you can get notified when you receive a message. As free software, the code of Delta Chat is open for all who want to take it and build upon it. In the future, if the developers of Delta Chat make a catastrophically bad decision and take the app in an undesirable direction, users can take the code and fork the project. This contrasts with closed-source apps from corporations that can take their products in any direction they like. By relying on free software instead of closed-source programs, you actually control your computing. I’ve spoken at length about how running this type of software is like owning your own home rather than renting it. The same applies here; if you use Delta Chat, you don’t need to worry about it going away in the future. Whether it is Telegram, WhatsApp, or Messenger, you are required to register a username and password to use these services. A major flaw in this design is that anyone can try various passwords and potentially break into your account with your complete chat history intact. Sure, there is encryption in Messenger, where you need a second PIN and two-factor authentication in Telegram, but breaches happen all the time. Unlike before, when you used to sign in to your email account to send and receive messages, the primary way to do it now is to create an account on a chatmail relay. The resulting email address is a random string followed by the name of the relay you pick. This means you can start and begin adding contacts Without a username and password, you either need to ensure you have a backup or at least one device running your Delta Chat profile. The primary way to log in on another device is to go to the settings and add a second device. Then, you’ll just scan a QR code with your new device, and it’ll log in to your account and sync all your chat history and contacts. To end users, Delta Chat just looks like any instant messenger; however, it is really sending your messages as encrypted emails to your contact. This is pretty cool from a censorship perspective, as it makes the service more difficult to block. Previously, the main way to use the app was by logging in with email, but nowadays, it’s recommended that you use chatmail relays. Chatmail relays temporarily hold messages in case your device is offline. They are cheap, simple servers that don’t store data as group states. Other information, like your name and avatar, only exists on your device and the devices of those you share your contact information with. The relays are also decentralized and operated by various groups and individuals. It is even possible to set up your own chatmail relay, but most people will want to use one hosted elsewhere. To keep your messages secure, Delta Chat uses a secure subset of the OpenPGP standard that gives you automatic end-to-end encryption. It also uses Secure-Join to exchange encryption setup information through QR-code scanning or invite links. Autocrypt is also used to automatically establish end-to-end encryption between contacts and all members of group chat, but sometime this year Autocrypt v2 will be rolled out, bringing post-quantum resistant encryption and forward secrecy. The Delta Chat FAQ is an interesting read that explains many more details about the app. Credit: Pexels Delta Chat is unique among messaging apps because it is built on email, a technology that’s decades old and isn’t going anywhere soon. What’s more is that email is not centralized either, so it’s far more difficult for any authoritarian regime to disrupt the Delta Chat app. I haven’t spoken too much about features yet, so I will do that now. Delta Chat allows you to do one-on-one chats, group chats, and create channels. It also supports file sharing and making audio and video calls when chatting one-to-one, but it’s not available for group chats right now. At the time of writing, the calling functionality is disabled and can be enabled in Settings > Advanced > Debug Calls. I have used the video calling feature, and the quality is excellent. It works over WebRTC, another open standard. The app also lets you send voice notes, enables disappearing messages, and has its own app ecosystem. I did try playing chess one time there, but it was a bit spotty; though, we did manage to complete the game with a victory for me. To add people to Delta Chat, you can either give them your Delta Chat link or your QR code to scan. These are the only ways to add users, so you won't have any spam bots bothering you. If the people you want to chat with don't have the app yet, just send them your link, and it will take them to a webpage where they can install the app and then add you. It's really quick for them to install it and get started, which is nice. Credit: Microsoft. The Majorana 2 quantum chip unveiled in 2026. I do not think quantum computers are too far out now, and I do hope that Delta Chat is able to push out Autocrypt v2 sooner, rather than later, so bad actors do not attempt to collect encrypted communications and then decrypt them in the future using quantum computers. By getting people’s messages post-quantum-safe now, users won’t have to worry when quantum computers start cracking legacy encryption. Overall, I would recommend this app to people who are already past WhatsApp and Messenger and have perhaps begun using apps like Telegram or Session. It shares a lot of characteristics with these apps and goes a lot further than Telegram in terms of security. By being based on email, it is also resistant to censorship, and the lack of a username and password makes you anonymous (if you want to be) and safe from brute force password cracking attempts. Let me know in the comments if you’ve tried Delta Chat recently. Do you think it's a good bulwark against governments that are tightening their grip on the internet?
