Apple is expected to debut a new iPhone, iPad and iPad mini tablet later this year. Earlier rumors have suggested that the company’s popular 7.9-inch tablet would see a variety of improvements over the previous model. According to MobiLeaks, the second-generation iPad mini will be equipped with an improved Retina display with 2048 x 1536 resolution that works out to 324 pixels per inch, and it will feature Apple’s dual-core A6X processor as well. The device’s camera will reportedly be upgraded with an 8-megapixel sensor on the back and a 2-megapixel sensor on the front. The thickness of the nextÂ iPad mini is also said to be increasing from 7.2mm to 7.5mm, likely to make room for a larger battery. Apple is expected to release the second-generation iPad mini sometime this fall.
