So I have an 8gig class 2 sd card. I partitioned it to 4gb. I was reading in another post the other day that 1gb was probably plenty and that the 4gig may actually be causing lag. It also seems to run outta space faster than normal. Just wondered if anyone has had that issue. Im also using twrp, and want to keep my backup. suggestions on keeping it? Im so sick of re downloading apps. I use tb, but it seems to dork up every backup. Also, I have another 8gb card, partitioned the same way. Windows xp only sees it as a 4gb. It only formats it as a 4gig too. Thanks.
