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.

Last week a series of screenshots were posted on Twitter indicating that Samsung’s in the process of working on a major design overhaul for its famous TouchWiz user interface which gets plastered over the top of the traditional Android OS on all of its current smartphones. Today, two new screenshots have emerged showing what appears to be an informative card based UI, similar to what Google created with Now.

A leaked engineering prototype of Normandy, Nokia’s first Android-powered smartphone, has been pictured out in the wild. Although it’s covered by a protective case, the design seems to lineup with the leaked press renders we’ve already seen for the budget smartphone.

We already know that Nokia’s been working on an Android-powered smartphone called Normandy that may never see the light of day thanks to the Finnish firm’s close relationship with Microsoft. And that’s an even more disappointing thought when you see its custom Android user interface in these leaked screenshots.

It looks like nothing we’ve seen before on Android, and I don’t know about you, but I like it.

Samsung appears to be working on a major overhaul of its TouchWiz user interface for Android. Leaked screenshots of the new interface — which sports a new lock screen and colorful new icons — surfaced on Twitter today, and it’s though this year’s Galaxy S5 could be the first handset to get it.
