I've already tried latest OmniROM and Android Revolution, but my phone is simply much slower and laggy in comparison to Galaxy SII (on neatrom) or Galaxy Nexus (on omnimetal). I don't really need much additional features and customization, I mainly strive to speed, performance and stability. Could you give me any recommendation on which ROM to try? Could it be possible that something else might be the reason for poor performance?
Also, it takes a lot of time to send MMS. Any ideas why?
