ZTE Racer is a pain in the butt!
On the plus side it is cheap (I got it on 3 for £70), it looks OK, and packs in plenty of 3G features for the price.
But the screen! By god it is near impossible to scroll...so sensitive it opens whatever you touch as you attempt to scroll. So unspeakably frustrating. I now only use it with a pencil or other input stick.
It also instantly locks its keyboard mid-call, and locks itself within seconds of not being used, despite my setting the longest possible lock-delay in settings. This doesn't, strangely, stop it sending gobbledygook messages to random people from my pocket, even when it is apparently locked! Go figure.
You really only get what you pay for with the Racer: an absolutely no frills, no subtlety, Android 2.1 base phone. It does the job. But there is so so so much better out there...!
