When searching for a pick, there were many with Micro USB ports, but only a few with USB-C so chose based on that. In the app, you choose what ear your working on, but found my brain needed the opposite view.
After initially pulling out chunks of wax, sometimes I feel blocked but can see it’s my ear canal being irritated, and with it clear, can use olive oil drops or moisturiser on a cotton tip to treat the sore areas.
What phone are you using? On Samsung you just open the picture in the native Gallery app, tap the three dots menu in the corner and choose Set Wallpaper.
If you’re not using Samsung then I would expect that brands picture browser to have a similar feature.
