Your phone’s lens can pick up a lot of dust and smudges that can affect image clarity, so give it a wipe with a soft cloth to clean it off.Prima di enter the live of the tutorial and spiegarti how to download WhatsApp on iPad, it seems only right to make some clarifications about the procedure that I am about to illustrate to you. This can often happen when you move your phone close to scan the code. If you’ve already made the lighting brighter but the QR code still isn’t scanning, make sure a shadow isn’t falling on the QR code. Try holding your phone so the QR code is inside the Nest app’s blue box and move it slowly away. Some phone cameras can’t focus as well as others at close distances, so you may have to hold your phone a bit further away. Try holding your phone about a foot away and slowly moving it towards the QR code. If you’re holding your phone too close or too far away, it won’t scan the code. Make sure it’s level with the surface that the code is printed on. Your phone’s camera may have trouble scanning the code if it’s tilted at an angle.
You can also try resting your elbows on the table to steady your phone. If it’s shaking too much, your phone’s camera can have trouble focusing. Put your Nest product on a counter, table or other solid object. If your Nest product is on a patterned background, try moving it to a plain surface and re-scanning the code. Patterns on a tablecloth, rug or wall can sometimes confuse your camera’s auto-focus feature and prevent the code from scanning. Turn on more lights or open the window shades and try scanning the code again. Your phone or tablet will not use the flash when scanning a QR code with the Nest app, so bright lighting is important.
