There have been a number of complaints about the facial recognition software that is used by Snapchat. While newer model iPhones such as the 6 and 6s have no issues the older model iPhones are not compatible. This means if you have an iPhone 4 or iPhone 4s you cannot use the face or selfie filters. It is also the case that a number of Android smartphones do not allow users to take advantage of the animated face filters.
If you are using a newer model iPhone and you cannot get the face recognition to work it is likely the case that you are in an area that is too dark. We have tried this a number of time at restaurants, sporting events or concerts and the face filters simply do not work. Even if you put the flash on you will find the facial recognition software will not pick up your face.
The only thing you can do to combat this is to sit in a place in which there is plenty of light. If there are shadows on your face you will find that Snapchat won’t recognize your face. If you are using an older model iPhone you may want to ask your parents for a newer one. Remember that the brand new iPhone SE is free with a two year contract extension.
You may also be able to find an iPhone 5s or 6 on Craigslist at an affordable price. If you are looking for a new iPhone please comment below and someone will likely be able to sell you one or offer options on getting an iPhone for under $100.
