What is the name of the rom? I mean whats the date rom u installed?
this one omni-5.1.1-20160619-golden-HOMEMADE.zip using twrp 2.8.7.3 , now im using a rom from novafusion called lineageos los13.0_golden.nova.20170328.zip, has android 6.0.1 and its stable without lag but i think that omnirom is still faster. maybe i should try another version of omnirom?
