Just realised that the glass over the camera lens on my Galaxy S7 has smashed. Have seen kits online and a weird video on how to replace the glass using guitar pics & a hair dryer .

In reality is it easy to replace this small piece of glass myself or try and find a shop that would be able to do this professionally? Knowing my luck if I did this myself I would probably ruin the whole phone and only had it since August.

TIA!
