Re: Why is it that when I downloaded android 4 on my google nexus 4 i can's send pictures now
Welcome to Android Central! What do you mean Android 4? Do you mean 4.4.4?
Are you trying to send pictures via the messaging app? Try booting into Recovery Mode and wiping the cache partition, which won't erase any personal data: Reset: Google Nexus 4 | T-Mobile Support
