Audio DAC should also work using GPIO DACs e.g. What I can confirm is that audio is working very well via bluetooth headsets, but it doesn’t work for me via the 3.5mm audio jack of the Raspberry Pi 4.Īccording to the developer, audio should work via HDMI, the 3.5mm audio jack, and Bluetooth. I don’t have a touchscreen, so I cannot confirm that it’s working. What also works is support for touchscreens with multi-touch, including USB touchscreens and Waveshare SPI touchscreens. The developer is still working on enabling hardware video decoding and encoding, but for now you’ll have to settle with hardware accelerated graphics (V3D, OpenGL and Vulkan), as well as software decoding and encoding. Web browsing works well too, and you can even play YouTube videos, but not in HD or FullHD formats, yet. Of course, you can even enable a dark mode, which looks really cool. Swiping up on the home screen will reveal all installed apps (Files, Calculator, Calendar, Contacts, Clock, Recorder, Gallery, Music, Browser, Camera), including the Settings app, from where you can set up your entire Android OS. Further swiping down will reveal more quick settings. Once connected, they will be remembered after reboot and you can easily turn them on and off if you swipe down the screen from the top with the left mouse click. There are two workspaces (home screens) available by default and you can easily customize widgets or the wallpaper by long-pressing the left mouse click anywhere on the home screen.Ĭonnecting to Wi-Fi (both 2.4Ghz and 5Ghz networks are supported) and Bluetooth is quite easy from settings. There’s no initial setup of a Google account or anything, so once you boot the operating system from the microSD card, you’ll enter the desktop session immediately. The image is distributed in the same format as any other Raspberry Pi operating system, which means that after you’ve downloaded the image (see direct download link at the end of the article), you’ll be able to easily write it on a microSD card with the official Raspberry Pi Imager utility or a similar tool. Here’s my first look!Ĭreated by renowned XDA member KonstaT (KonstaKANG), there’s now an unofficial LineageOS 19.0 build for Raspberry Pi 4 Model B, Raspberry P 400, and Raspberry P Compute Module 4 (CM4) computers, based on the Android 12 mobile operating system and, to my surprise, it runs quite well. If not, see the link below.Even if your smartphone doesn’t run Android 12 yet, you can now use Google’s latest mobile operating system on a Raspberry Pi 4, 400 or CM4 computer. Bootloader - Is your bootloader working? Take your SD card out of the Raspberry Pi and power the Pi back on again - if you see the green LED flashing (usually a pattern of 4 flashes) - the bootloader is fine.Cheap power supplies are a common cause of issues. Power - Are you using an official Raspberry Pi USB-C power supply with your Raspberry Pi 4? We only recommend this power supply as it has been rigorously tested for use with the Pi 4.Raspberry Pi OS - Are you using a freshly downloaded copy of Raspberry Pi OS? The Pi4, in particular, doesn't always work well with older versions of Raspberry Pi OS so we suggest a fresh copy.SD Card - Are you using a Sandisk or Panasonic card - we only recommend these brands, cheap no-name cards can cause endless issues.Only use the second port when using 2 screens. HDMI port - If you're using a Raspberry Pi 4 with 1 screen, make sure it's plugged into the left port (labelled HDMI0).Grab a coffee, let it sit for 5 minutes, and if it's still not booting check the additional items below. Let it run - Sometimes (usually the first boot of a fresh SD card image) the rainbow screen can display for a good 3-4 minutes.If you're seeing a rainbow screen when powering up your Raspberry Pi, please try the troubleshooting steps below:
