Over time, it's become more common to see Android phones with 6GB, 8GB, or even more RAM and at least 64GB of storage. This is happening even with cheaper Android smartphones, but the minimum hardware requirements are also increasing. The days of using smartphones with less than 2GB of RAM are long gone, but Google is now making it official with an update to its GMS requirements.

As Google announced on the Android Developers blog, starting with Android 13, a smartphone will need at least 2GB of RAM and 16GB of storage to run Google apps as part of GMS. This applies even to Android Go devices, which are typically geared towards phones with low RAM.
Many early Android Go phones had 1GB of RAM and 8GB of storage, but thankfully the market has adapted over time and it's not uncommon to see Go devices with 2GB of RAM or more these days, so this news won't massively transform the entry-level Android phone market.
The truth is that 1GB of RAM hasn't been enough for even basic use for a long time, and if a phone in 2022 came with 1GB of RAM, you should really avoid it. Right now, 2GB of RAM is the bare minimum for running Android.
