I bought an Otterbox impact case for my Eris last week. I have bought other Otterbox products before and they are top quality. However, after installing the case my battery drained in 3-4 hours. It seemed like the phone was searching for a signal. After removing the case, everything returned to normal. Also, the proximity sensor didn't work even though the hole for it was positioned correctly. I noticed that if you use a flashlight you can see a small reddish dot below and to the right of the proximity sensor. This dot is covered by the new Otterbox case. Is that an antenna or some other sensor ? I emailed Otterbox and they said they haven't heard of this issue before and offered to send a call tag and have it returned and credit me towards the other Eris case(commuter) which doesn't cover that area. Anyone have any experience with this problem ? Anyone know what that reddish dot is ? Thanks in advance.
