Samsung has confirmed that it is researching iris scanning security technology for its future smartphones, but its upcoming Galaxy S5 may employ a fingerprint reader instead — just like Apple’s iPhone 5s. A Galaxy S5 APK file named “FingerprintService” has been leaked ahead of the handset’s release.

Samsung’s upcoming Galaxy S5 could get a pretty nice camera upgrade, according to a leaked test photo that has surfaced online. The photo’s accompanying EXIF data shows it was taken with an “SM-G900-V” — which is believed to be the model number of the Verizon Galaxy S5 — with a 21-megapixel camera.

Samsung has today announced that it will hold a press event in Barcelona on Sunday, February 23 — the day before Mobile World Congress 2014. But this is not the Galaxy S5 event some of you may have been expecting; Samsung plans to unveil its first Tizen-powered devices instead.

Samsung “isn’t sure” about announcing its next-generation Galaxy S5 at Mobile World Congress next month after reliable Russian tipster Eldar Murtazin revealed the date of the event. Murtazin now believes the South Korean company could delay the announcement and hold a special event in London as previously reported.

Samsung’s new Galaxy S5 will make its debut on Sunday, February 23, one day before Mobile World Congress 2014, according to respected Russian tipster Eldar Murtazin.

The device is expected to introduce a new TouchWiz user interface on top of Android 4.4 KitKat, as well as new high-end specifications, an improved rear-facing camera, faster processors, and possibly even iris scanning technology that will allow users to unlock the device with their eyes.
