Will the Samsung Galaxy Nexus run Pokémon Go?
Is it possible to play Pokémon Go on an old phone like this?
What about if I install Lineage OS to play with Pokémon go?
Your device would not be able to run the game (at least not in any playable fashion) If you visit the Pokemon Go Store page while on the device, it will likely tell you as much.
Your device is a Galaxy Nexus, here's it's specifications (the ones that matter):
- Operating System: Stock: Android 4.0 (Ice Cream Sandwich), upgradeable to 4.3 (Jelly Bean)
- Display Resolution: 1280×720 (720p)
- RAM: 1 GB
Now, according to Pokemon Go's stated requirements:, and an earlier question here: What is the minimum RAM required for Pokemon GO?, here's what you'd need to run Pokemon Go:
- Operating System: Android 4.4+
- Display Resolution: 1280x720
- RAM: At least 2GB, if not more
The Galaxy Nexus does not meet the minimum RAM or OS requirements to play the game. Furthermore, rooting the device and installing another OS will likely not work either as rooted devices are apparently not supported either - even if you did manage to get it installed it still wouldn't meet the RAM requirement.
You should look at upgrading to a newer device.
