Apple iPhone 4 specs

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.
