There weren’t any problems with installing and running Slideshow. The user interface was fairly responsive, with occasional slowness – subjectively faster than LineageOS on RPi 3B+, slower than LineageOS on RPi 4B. After flashing the image on the card, insert it to your RPi, power up and let it boot. After opening the installer, you can pick which image you would like to install (for RPi 3 in this case) and on which drive (micro SD card) you would like to flash it. Installation of emteria.OS starts with free registration on their website and downloading their installer on your computer. For stable operation, paid Personal or Business license is required. You can use their free evaluation version for testing (which is what I did), but it is not allowed to use it for commercial purposes, it automatically reboots every 8 hours and there are occasional pop-ups informing you that you are running evaluation version. It is important to note that emteria.OS is a commercial product. They don’t support Raspberry Pi 4 so far and the provided Android image doesn’t boot on this version, that’s why I tested it only on Raspberry Pi 3 B+. They offer Android images based on Android 7.1 for Raspberry Pi 3 B and B+ among a few other single-board computers. As the standard resolution for TVs and screens is slowly moving from Full HD to 4K, this resolution is almost unusable for digital signage.Įmteria.OS is a commercial Android distribution aiming at industrial usage, developed by German company emteria GmbH. The maximum screen resolution supported by this image is 1280 × 720 (which is also the default resolution).Commercial use is not allowed, that means you cannot use it for displaying advertisement for your company. Because the Android image contains parts licensed under non-commercial license, you can use the image only for personal or educational use.Both RPi 3B+ and RPi 4 managed to play 720p H.264 video without lags, 1080p H.264 video was lagging on RPi 3B+ and smooth on RPi 4B.įrom the point of digital signage, there are two big problems with this distribution: It took few seconds for the Slideshow interface to render all panels, but after everything was loaded, RSS news displayed as moving text (which can be laggy on slower devices) were smooth.Īs this build doesn’t support hardware video decoding (although Raspberry Pi as a hardware supports it), all videos are decoded using CPU. Installation of Slideshow was without any problems on both versions, as well as the basic setup and upload of files through web interface. The user interface (UI) on RPi 3B+ felt a little bit slow, sometimes one had to wait a second or two for Android to react on a click. After some time (cca 3 minutes on RPi 3B+, 1.5 minute on RPi 4B), you will be greeted by Android setup screen, where you can pick your language, time zone and other basic settings. Download the image, unzip it, flash it to MicroSD card (size 8 GB+) with Win32DiskImager, insert it to Raspberry Pi and power it up. Installation of LineageOS to Raspberry Pi is quite easy, almost the same as any other OS for Raspberry Pi. Because of the different bootloaders, you can’t boot Raspberry Pi 3 version on Raspberry Pi 4 and vice versa (I tried). Both are based on the same LineageOS 16.0, which is based on Android 9 (codename Pie). At the time of the writing, there are two versions available – one for Raspberry Pi 3 B and 3 B+ and one for Raspberry Pi 4. Software developer KonstaT ported this distribution to Raspberry Pi as well. LineageOS is an open-source Android distribution for various devices.
