I got my new lg g3 and when i try to download something it says that there is insufficient space on the device. I looked up some solutions and google play services doesn't let me uninstall updates. are there other solutions? Btw i have about 8 gb of storage left
Depending on where your phone is saving your downloads to, it may have insufficient space there (most likely the internal storage). Then your system may have already notified you that the system may misbehave and you should clear some storage.
If not, then your storage may be messed up and the system is not allowed to write to a specific folder (I don't know what you try to download and what you use to download that).
