Apple India — iphones defect

Address: 500034

I have seven iphones from apple, all of them having same defect. The call log details that are written are overlapping as though it is some glitch but the happens for all call details. The time duration and call type gets overlapped making it hard to understand what it reads. Horrible defect from a long time even in new xmax plus phones we have. We bought our handsets from not only india but other countries as well. The constant glitch makes us doubt the phone quality. Being a dedicated apple customer this is very unexpected, as we have more than 15 apple handsets including ipads. I hope apple can solve this issue as soon as possible.
