I started getting screen issues out of the blue a few days ago. First screen was hazy then it went berserk flashing with lines across it. Took it to the Samsung store to be told this was an S5 known issue. Because it is waterproof the case is glued together so it is a lengthy process getting inside. They have sent it to Carphone Warehouse to be fixed and will be a least 10 days possibly 20. I am told that Apple would simply have replaced the phone so this is poor from Samsung. Be aware.
