Have you noticed your Galaxy S6 or Galaxy S6 edge killing apps too quickly during usage, and still taking up a lot of the available RAM at all times? Well, you're not alone, as this issue seems to be affecting a lot of users out there, some of whom have voiced their concern over on the XDA development forums.
I've personally been irritated by the horrendous RAM management on my Galaxy S6 edge – apps like WhatsApp and Facebook, which usually stay in memory and show up instantly on devices with 2GB+ RAM, often take time to load as the phone keeps killing their processes. It's a problem with browsing as well. Chrome will often reload when you go back to it, even if you have only opened one other app after sending it to the background.
Android is designed to remove older apps from memory to free up RAM for current tasks, but the Galaxy S6 and S6 edge seem to take it too far despite having 3GB of RAM (and considerably less bloat than previous Samsung devices taking up memory.) However, the fact that despite killing apps too quickly the phones seem to have very little available RAM suggests it's a bug and not something deliberate.
Some might say that this is a fault of Android 5.0 Lollipop – indeed, Lollipop does have a memory leak issue, but that doesn't make the OS aggressive against keeping apps in memory on other devices. Hopefully, Samsung will fix what is one of the very few issues on the Galaxy S6 and S6 edge's software through a software update as soon as it possibly can, as there doesn't seem to be any stop-gap solution to the problem at this point.
