I updated my galaxy s4 with the over the air update a few days ago. I cleared the cache and did factory reset...
Messages now wont send....I have to restart phone and hope they send. ... my battery life also sucks. How do I downgrade to a previous operating system or fix these issues

Re: messaging issue
you cannot downgrade due to bootloader lock and also it will damage the EFS folder
may be the messaging settings have been change
go to message--> settings
