Even though the phone had been released in May 2015 it is still a good mobile phone today. Its specs are still very good even today.
The size of the phone is a standard Xperia size of 150.3 x 77.4 x 7.9 mm, uses a nano-SIM and weighs in at 147 g which is about the same as other phones in the range. The phone has a large screen with an IPS LCD capacitive touchscreen with 16M colors and a 5.5 inches (~71.7% screen-to-body ratio) screen size.The phone also has a very good screen resolution at 1080 x 1920 pixels with a pixel density of ~401 ppi. The screen is scratch resistant and it is a multitouch phone with up to 10 fingers at a time.
Much like the Nokia Xperia Z3+ the Xperia C4 comes with an Octa-core processor. This is a 1.7 GHz Cortex-A53 Octa-core. The GPU is a Mali-T760MP2 GPU using a Mediatek MT6752 chipset. All of this is running Android OS, v5.0 (Lollipop), upgradable to v6.0 (Marshmallow). You can search the rest of this website for more information on the hardware. The hardware on this phone is good and there is more than enough memory and storage space as well.
With 16 GB of space and 2 GB RAM and a expansion slot for a microSD card with up to 256 GB of additional space, the phone makes for a very good long term investment. With a 13 MP auto focus camera you can snap away at your hearts content. With this hardware the 1080p video recording is possible which is high definition recording. There is also the usual geo-tagging, touch focus, face/smile detection as well as panorama. Note that there is a secondary camera in the form of a 5 MP, 720p camera with an LED flash. Yes, there is a flash on the front as well as the rear. There is also active noise cancellation with a dedicated microphone.
The Wifi on the phone is Wi-Fi 802.11 a/b/g/n, Wi-Fi Direct, DLNA as well as hotspot. There is also Bluetooth v4.1, A2DP as well as aptX. A-GPS, GLONASS as well as NFC is also available on the phone as well as an FM radio and an accelerometer, proximity sensor as well as a compass. There is no Java but it does offer an HTML5 browser as well as SMS (threaded view), MMS, Email, IM and Push Email. There is also ANT+ support on the phone.
Overall its a good phone in this price range but I would still prefer the Xperia C which is the same price. With a non-removable Li-Ion 2600 mAh battery it gives you about 634 h (2G) of standby time as well as 13 h (2G) talk time. Many users have preferred to do the marshmallow update when they got their phones as the phone appears to be stable (touchscreen issue) after the software update.
