Apple iPhone 4 Specs

Apple iPhone 4 Review


The iPhone 4 is now boxier, with the rear side now flat, instead of rounded. It will keep the 3.5-inch display diagonal, but will quadruple the pixels to 640x960, making it the highest-resolution screen on a smartphone to date. Apple actually calls the new screen Retina Display, because it shows 326 pixels per inch, while the human eye can only distinguish around 300 ppi. In addition, the screen will utilize the LCD IPS technology (same as in the iPad). The other new stuff includes a front-facing video call camera, 5MP main camera lens with LED flash and 720p HD video recording, Micro-SIM slot, instead of ordinary SIM, a secondary mic for noise-cancellation and a lot of other new features.


  • Small dimensions (4.50 x 2.31 x 0.37 inches)


  • Thick body (0.37 inches)
  • Proprietary USB connector

Mine works but it is activation locked and shattered
Phone owned for more than a year

I had it since 2017 and i lost it and i found it. I changed the wallpaper and reset it and it had a activation lock error and i dropped it in the plastic floor and it broke in this floor, even though it is plastic and always had a shattered back

If you haven't bought this phone yet, (think twice) Here's why
Phone owned for less than a year

This phone was only good during the first week i had it. I like how these phones have above average smoothness of moving from screen to screen but this phone lags so bad!!! For example, i'm watching utube and i wanna move the screen to landscape and it takes about 5 seconds before it could finish. This phone had more problems than combine all the problems i had with my past phones! And those phones were androids. My phone couldn't produce sound unless i plug in my earphones! And it doesn't stop there, it even stops playing even if i had my earphones in it. So i have to reconnect my earphones, play the song again, and again. My apps often keeps crashing, especially when I'm on utube, it starts to lag then boom it closes my app. Right now, my phone can't even open my text message and if it does it doesn't show any of my past text messages. I can't also call anyone (really no idea why). It forces me to sign in to iCloud, when i don't even need it and when i already turned it off! It keeps on popping, and it doesn't stop unless I "sign in" to it. And, it lags so bad. It's very slow and i've only had for around 5 months. While this phone has some nice features, those features are just "iClouded" by problem the phone has. I've seen so many customers complaining about similar problems I encountered and there's very little help i found on google or no solution at all to some problems. I would not recommend this phone at all. If you haven't bought it, and still trying to decide, well here's my experience with this phone. I wish i just made up these problems but no. Won't be long til i switch to a different phone. Maybe these are only found on some people's iphone.

Very slow phone
Phone owned for more than a year

The phone was nice and fast when i bought it. but it still lags a lot behind all the new models and other android phones for cheaper price. Internet gets disconnected when you are on 3g and have to reset when it goes to 2g.
