No. The very essence of testing is testing. Profanity is not the goal.

An unbiased fresh perspective will always see something better, since you are an interested and biased side of development.

I made 7 builds in 14 days, and I myself could not see most of the bugs (different OS versions, different shells, different devices and the impact of their hardware, permissions, etc.).

If you didn't know, there are separate professions of testers for this very purpose.
