Looks like, Sony is already set to introduce a successor to its entry-level Xperia E3 smartphone, which was released in September this year. Although the availability details of the upcoming Xperia E3 successor (likely to be dubbed as Sony Xperia E4) are unclear at this point, it is expected to be announced in the coming weeks.

According to Polish blog TeleGuru, which has got its hands on a prototype unit of the E4, the smartphone seems more like a variant than an upgraded successor. It will sport a 5-inch qHD 960x540p display and come with 1.3GHz quad-core MediaTek MT6582 processor, 1GB of RAM, 8GB of internal storage, and microSD card slot. The phone will also feature 5MP rear camera with LED flash, Android 4.4.4 and 3G connectivity. Other specifications are unclear at this point.

A dual-SIM version of the phone is also said to be in works, which is not a surprise, given Sony’s track record to release single SIM as well as dual-SIM versions of almost all of its entry-level and mid-range smartphones.

We are hoping to see an official announcement at CES.
