Sure, if it was found for whichever library code was used on that device, and if you also found a way to use it to get the OS to expose data that it usually wouldn't. I'm not saying that someone couldn't work out a way to exploit that phone, I'm saying that it's not going to happen because there's no point (and also wouldn't have been one while I was still using it). As a practical concern, I'm more worried about my phone now (an up-to-date Android) than I am about any feature phone, including recently-released ones.
