The most frustrating part when using this phone is the battery heating problem. Often, even when I don't use it much, the phone's temperature always increases. This issue becomes a source of inconvenience, for I initially planned to make it my primary phone. Another thing that sucks is the absence of an audio jack, and the camera needs lots of improvements too. It has a full screen on a lighter note, which I like, but it's still not an edge-to-edge design. I love the 6gb RAM and Octa-core processor since they make the phone's performance a lot smoother and reliable.

iPhone 4 is the perfect phone for video calling (FaceTime), my parents. I love their FaceTime app, because it is straightforward, especially to my parents, who are not tech-savvy. The camera's quality is even better than most phones now, and the speaker is not gravely in sound. Another simplistic feature that I love with this phone is the ease of use because it is easier to navigate through the phone, and there are no unnecessary pre-installed apps. Overall the user interface is just plain and simple. If I were going to nitpick about the things I do not like with this phone, it is the thick width and slightly heavy. It is also somewhat uncomfortable to hold for long because of the sharp edges and lines, and the material used for this phone is aluminum. But I would rather have this phone than those that use plastic for the phone's body. Other than those, there isn't anything more to dislike about this phone. It is a compact phone that contains all of the essential tools and apps. I also don't have to feel pressured to personalized my phone because the phone cannot be customized. Basically, this phone is for those who want to keep it simple.
