Am I the only one who hates to use the home,back,calland power keys? They are hard to use, and oftentimes you end up puching the navigation key instead. The only way to accurately use them seems to be with the fingernail, which I'm sure will eventually damage the membrane.
I cam across a sheet of cheap button stickers I bought a long time ago for another phone. They are raised transparent stickers. I used four oval shaped ones to place over those 4 keys.
It is so much easier now!
I am attaching a picture of similar stickers. They look bigger in the picture, but fit nicely inside each slot with room to spare.
They are mostly found in asian stores, and perhaps in cell accessory stores or dollar stores!
