    Galaxy S3. Rooted. The ES File Explorer doesn’t see the root. Neither does Titanium Backup. Cachemate does as does Root Call Blocker.

    Any ideas? Thank you!!

    I should add that my S3 had no issue with wifi or 4G before I rooted it. After rooting wifi and 4G are sporadic at best.

    Thanks again.
