Never experienced Camera lens scratch on any Android I owned, then again I put cases on my smartphones like most people do. I know it was a thing for the LG V20 back in 2016 with cracking.
Which particular Android in 2018/2019 is having a lens scratch issue? Didn’t know it was as widespread as you are claiming.
Anyway this is going far off what OP asked.
OP if you want to give the P30 Pro a go, try it out!
