Presenting regularly to camera clubs on all things smartphone photography, it is amazing how many of us miss this number 1 tip to avoid those frustrating blurry photos.

The above video is a sample out of my new... Blurry to Tack-Sharp Photos: 4-Step System.

Your smartphone lens is very robust and can tolerate an ad-hoc wipe over with any material you have access to. Before you do, I recommend checking the lens is clear of any foreign matter that may scratch the lens.

Do:
> Check the lens for any foreign matter - quite often blowing on the lens will work
> Lint-free cloths are great for cleaning most of the flat surfaces you can access
> A cotton bud is perfect for those difficult to access areas on and around the lens
> If you have a phone cover additionally clean the inside of the cover
> If you have a lens attachment, make sure to clean the front and rear lens

Do not:
> Use a cleaning solution. If you feel you need to, then apply a cleaning solution onto a cloth and not directly onto the lens.
> Use a tissue. This actually leaves more on the lens than it removes!

A 'big' camera technique is to clean in a circular motion from outside to the centre. This is most effective to remove fingerprints, oil, smudges, dirt, and dust on larger lens attachments.
