Will an HTC one x case fit the HTC one x plus?

Yes, an HTC One X case will generally fit the HTC One X Plus, as both devices share similar dimensions and design features. However, it's always best to check the specific case measurements and compatibility details, as some cases might not accommodate slight differences in button placement or port access. If you're considering a case for either device, look for one explicitly labeled as compatible with both models for the best fit.
