Apple seems to be discouraged by applications that are so hungry on the processor that they do not work on devices under the top that are still sold. Thus, when choosing Bluetooth or the front camera, if your application does not need them, most likely the application will be rejected.
The best bet may be to improve the performance of your application or to edit the description of your application with decent performance requirements markedly listed, and there are poor ratings and reviews from customers who cannot read.
