I purchased the kit to add inductive charging via the Palm Pre Touchstone base. After a few false starts, I think I have the sticker in the right place. This works well, but the phone frequently slides off the touchstone when a message comes in (vibration). Turning this off will help,but I'm just wondering if the phone is too heavy for the touchstone? Also, I have one of the samsung OEM cases with the cover flap currently on the phone. Would the cover flap be adding too much weight? Just wondering if anyone else has experienced this?
