Product review (1 stars): This dryer has all kinds of problems, which apparently cannot be resolved by technician.
I have had this dryer for about a year now.  From day 1, I have the following issues: sheets and blankets get rolled into a large ball, so that they are dry on outside, and wet in the middle.  On normal cycle, it will sit on 1 minute remaining for an hour.  I must always stop the dryer manually.  If I use any other cycle besides normal, the dryer time will initially start out around 45 minutes, but after 10-20 minutes it will jump to 3-1/2 hours.  I have called Samsung support, and they sent the local person out, who obviously had no clue on how to repair this dryer.  He simple ordered a new computer, and replaced this.  Didn't change a thing, other than to negate any profits Samsung made on this dryer sale.  The software is obviously defective, and probably the dryer sensor is defective.  It is also noisy running.  It sounds like things are squeaking and rubbing against the drum while running (sounds like an old piece of junk).  I have an extended warranty, but don't know what to do about it???  And after service call, Samsung reps will call you to try to sell an extended warranty, instead of asking if your problem was resolved satisfactorily.  The computer has never had an software update sent to it, and I am thinking that Samsung will never bother with this (for example, change performance to prevent sheets rolling into a ball, or to prevent dryer from trying to run for over 3 hours, or 1 hour when 1 minute is displayed).
