Mike I have four Xtreme 4 cams and one Xtreme 5 cam, had to send one of the Xtreme 4 cams back due to ants infesting it and causing the same problem to my LCD display as yours. Wildview was out of stock of the Xtreme 4 cams so they sent me a new 8 MP. stealth cam to replace it that hasnt even hit the market yet.
As far as slow trigger speeds, all Wildview cams have them, but they have a very wide angle sensor and a long range flash to make up for it. So if your putting your wildviews over trails etc. just set them 11-13 feet off the trail and you will get pics of every deer that walks down the trail because the deer will trigger the sensor to the far left or right and by the time the deer gets right in front of the camera it will snap a pic, but the key is positioning the cam atleast 11ft off the trail as shown in the 2nd pic. below. Over all my wildviews have performed above expectations and I will continue to purchase them in the future. Pike
