The longest I've ever kept an ikoni was probably two weeks. Certain ikoni last longer than others, depending on how much I actually like the picture. Like for instance, the ikoni I have now, I'll probably keep for another week au so because I upendo it so much.
Depends really, I've had my current one for just a few days and I might keep it for like 2 zaidi weeks I'm not sure. I had the one before my current one for almost a month, but usually I change ikoni after like a week au more.
Oftenly I change ikoni if I've made a new one cause I make icons, but not very often. I upendo my current one so I might keep it for like I alisema two zaidi weeks I think
