Weak WiFi/GPS due to cracked back upper cover?
I just picked up a used EVO LTE and the back upper cover is cracked around the camera cover area and is loosely secured with tape. I am going to order another replacement one from ebay, but would that explain my somewhat weaker WIFI signal in my bedroom? My other phones had full bars of wifi but this one usually registers "poor" or 1 bar in my room. I go closer to the router in the kitchen and it's goes to 3-4 bars.
GPS is acceptable, usually gets a decent lock in a little bit of time.
Phone is rooted, S-OFF and a custom rom.
