does anyone have an IPhone 5C? idk if it's just me but I can't update to the newest IOS update ->> 10.2.1 and bc of this, my phone is glitched and lags and I can't switch keyboards and it crashes and types when I'm not typing any 5C owners?
Well there's your issue. You're using an iPhone (ew). Jk, look it up on an actual support website/Google.
I think your iPhone 5c cant upgrade to the latest version of IOS because its old. A similar thing happened to me I used to have a Samsung Galaxy S3 and tried updating it to Android 5.1 lollipop from Android 4.4.2 but cant because the phone is old and cant upgrade to the newer Android updates just simply because. All I can say is that the best way to solve it, is to get a new phone like I did . I miss my S3 but my N̶o̶t̶e̶ ̶7̶ Galaxy S7 is A LOT better than my S3.
what do you mean idk? When did you get your iPhone 5c? Also Galaxy is better than iPhone. Read the Facts
Or maybe the iPhone 5c isn't compatible with the latest version of iOS. Same thing happened here to my galaxy s3. It couldn't update to Android 5.0 Lollipop and I got stuck with Android 4.4.2. So my only choice is to get a new phone (like I did) or just keep the update you have and deal with it
