I also have had times when I was unsure whether to continue using iPhone or change to Samsung. People say that the updates for Samsung last more time, which is good if you want to keep your phone longer. Plus, the cost of iPhones these days can really add up.
Based on the information I collected, Samsung's Galaxy S series is very reliable, particularly their most recent versions. Their cameras are excellent quality and it appears that the general functioning is comparable to iPhones. Additionally, playing with the customization features on Android can be enjoyable if that interests you.
But remember, there could be a small learning challenge because you are familiar with iOS. It really depends on what you prefer personally. If you have put a lot of investment into Apple products or if there are iPhone features that you especially like, it could be better to continue using the familiar system.
If you are in the mood for adventure and interested in experiencing something different, consider trying a Samsung. However, remember to balance your iPhone 13 Pro's trade-in price and its payoff amount with the initial deposit required for the new Samsung. It's all about finding the best fit for your needs and budget.
