  1. This is the one thing that I can’t stand about IPhones… Never had a time when I could download the photos and videos effortlessly and flawlessly to my computer, without having major issues. I have had a new IPhone since as long as they have been out, andthis issue is getting really old and definitely something to consider when purchasing a new one. This is a repeated issue with this phone unless of course, you have a MacBook…

  2. I am dropping iPhone for good! It is incredible that I cannot transfer videos from my daughters to my laptop. The fix above worked for pictures but not for videos. In fact, some videos good damaged beyond repair. Bad for Apple!!

    Will be buying an Android instead of their iPhone 12 Pro Max. That’s a lot of money they will be loosing! Just because they are stubborn and “too good for their customers that use PCs”.

  3. Keep originals solved my problem too. I’ve lost 2 days of work over this flaw, and I can’t believe that Apple hasn’t fixed it yet.

  4. THANK YOU THANK YOU. I’m so glad I found this. Switching to ‘Keep Originals’ fixed my problem. And sped up the file transfers I’m trying to do manually. That was so frustrating.

  5. If you don’t need HEIC then go to settings>camera>format and choose most compatible. You will get .jpg/.h264. Then you can transfer without conversions.

  6. once you download it after you check ” keep originals” , open it in windows veiwer, when you do it will prompot you to buy something from the microsoft store for 0.99$ and it will say codec or something. anyway sign into to paypal or enter your card info and buy it, then it will work. its something about the format that is being transfered with “keep originals” cheeked, that only allows you to have the sound from the file. yes the file will be smaller but when you buy the thing from the microsoft store it will havw the vid in it! please know Jesus is the way the truth and the life!!! ANd He loves you all so very much!!! He just wants to make you family again!!!
