Four years ago, the Raspberry Pi Foundation announced the Raspberry Pi Model B. Today it publicized the new Raspberry Pi 3. Equipped with a WiFi Module (802.11n), Bluetooth 4.1 and a 64bit Cortex-A54 CPU with four 1.2Ghz Cores. It’s the fastest Raspberry Pi available to date.
In my blog post from Sep. 2015 (Speeding up Nexus 7 (2012) Tablet after Lollipop upgrade) I evaluated several options to get the Nexus up to speed again even with Android 5 (Lollipop).
But even with the changes in place I still got a lot of lag and unresponsive apps. I considered a downgrade to 4.4 when I noticed that there is a Android M Firmware for the Nexus 7 on XDA-Developers.
