Wait for Full Screen Touch ID
A new iPhone rumor from Barclays analyst Blaine Curtis hints at a new version of Touch ID on board the 2020 models.
According to Curtis, the new iPhones might include acoustic fingerprint technology, something that could allow for full-screen Touch ID.
This is not the first time we've heard this rumor, but it's the first time we've heard it mentioned for the 2020 iPhones.
If true, it could mean that the 2020 iPhones come with a biometric setup like the Samsung Galaxy S10's. The Galaxy S10 uses an in-display fingerprint reader.
Ming-Chi Kuo believes Apple's 2021 iPhone models will come with Face ID and an on-display fingerprint sensor. He doesn't mention anything about 2020.
If this is something you're interested in, think about waiting until 2020.
