Both record video and play back video in high resolution. iPhone 4, however, performs better in this category as well. The iPhone 4 possesses an A4 processor that makes web browsing faster and the capacitive touch screen more responsive. LG Ally remains competitive offering 600 MHz processor.

With accelerometers and Gyros both devices detect whenever the phone is rotated or turned and it will automatically adjust the image. Both are fairly responsive in the category. Because of the great processing speed, Apple's smart phone will allow the user to multi-task without slowing the phone. Both phones come equipped with rechargeable Lithium Ion batteries. Battery life is maintained through complex operations.
