is finally available directly on the web. This is a huge deal for me, and maybe no one else. Before now, I've been running a remote app view from my phone to see Snapchat. Even better, the web version of Snapchat can operate concurrently with the mobile version; prior to this, only special VIP accounts were allowed to sign in on multiple devices. I haven't fully tested if the privacy features work, but I do see that it blanks the Snapchat tab if it isn't active on the current display.
I also found that there's an App called Good Guardians that is available from the Samsung App Store for Android. This app provides some extra functionality to devices in the form of battery monitoring and use tracking, as well as precompiling small bits of Android software that are normally marked for JIT optimizations. It was possible to do this before using ADB commands, but it's a handy shortcut. I tried it out on a couple generic tablets and found a modest subjective improvement in Firefox and Tumblr start times; I suspect the performance improvement is probably not noticeable on the newest devices though. Here
is an explanation of what it does and a link to the APK. I got my copy of it directly from the Samsung App Store using a web extension called APK downloader.
