The vast majority of ROMs screw up your phone.
Loads praise the latest ROM, maybe without ever using, until you read through the hundreds of comments and see small niggles like..........
No SMS, no working microphone, no Wifi.
Strangely, I've never had any problem with a phone 'as is'.
'Working like the Nexus 4'. Now what does that mean. I dread to think.
The Nexus 4 is the nearest android phone i have had that comes close to the stability and reliability of iOS, my handset has been impeccable.
Not too sure if your latest ROM comment is with regard to the build of 4.3 that is floating about? If so then you will also know it was a test build lifted from a phone bought on Craigs List.
