Zflip 4, you close it, open it and the screen is blank. Tap on the screen and it comes on, intermittently. It was under warranty. Returned to Ingram Micros as per the instructions. Repair refused. Out of warranty they say. They tell the retailer that it has cosmetic damage. It has one green pixel, which just appeared one day. It doesn't affect the operation of the phone. It wasn't sent in for that. So I phoned them and the guy says, its a rubbish phone with poor engineering. The day to day use, basically ***** it. He will send me the report for it. Which I doubt. Now what? The warranty has just expired but the retailer has said my claim was made within the warranty period so as far as they are concerned its a valid claim. I'm waiting now for the phone to be returned. The phone has never been dropped and always kept in a case. It works fine, when it's open.
