Problems – Contacts Sync, Backup & Clean Pro for Google Gmail Review

I fixed my settings for one-way sync iphone to gmail. However, it still synced to the phone. I tried to use mass delete to get rid of these unwanted contacts but the app would only crash. After having to delete each of them individually, I synced a few more times to work out the bugs. Every time I synced, it would miss several contacts from my phone and continually make duplicates of the others into my gmail even though I have "merge duplicates" checked. Clearly there are serious issues to work out.
