Google confirms a new storage policy test, after some users reported that new Gmail accounts get 5GB, not 15GB, of free storage if they don't add a phone number (Akshay Gangwar/Android Authority)

Google is currently testing a new storage policy for Gmail accounts, which reduces the free storage limit from 15GB to 5GB for users who do not provide a phone number during account setup. This change has been confirmed by Google following reports from users experiencing the reduced storage capacity. The policy appears to be part of a broader strategy to encourage users to link their phone numbers to their accounts.
