Hello, I'm Chlod. An edit that you recently made to History of operating systems seemed to be a test and has been removed. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Chlod (talk &#124; contribs) 09:02, 2 January 2020 (UTC)

Hello, I'm DB1729. I wanted to let you know that one or more of your recent contributions to Android Studio have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse. Thanks. DB1729 (talk) 04:42, 25 July 2020 (UTC)
