From physical sockets Sharp C10 has USB 2.0 type C with OTG. It can be used as a socket for connecting earphones as well – unfortunately, C10 does not have a minijack. The smartphone can support microSD cards of a maximum capacity of 128GB, but it shares the slot with the SIM cards socket. The drive can only be used as a memory, we cannot install any apps on it.
Wireless communication options cover Bluetooth 5.0 and NFC, as well as the WLAN module in the 802.11 a/b/g/n/AC standard, which works in 2.4 GHz and 5 GHz channels. From mobile networks it supports 2G, 3G and 4G (including VoLTE). There is the navigation module as well, which quickly and ably connects with satellites when being outside of a building, and it’s indications are precise enough both for walking and driving navigation. The smartphone worked without any problems with Bluetooth earphones and a fitness band.
The sound quality of our interlocutors can only be described as average – the loudness is appropriate, bit the speaker moves towards higher tones, which is why the sound is not always pleasant. On the other hand, the microphone nicely catches the sound, and my interlocutors heard me loud and clear. The smartphone supports two SIM cards and we can choose the default card for calls or data transfer. However, there is not any built-in function of recording calls.
Memory and efficiency
The smartphone comes with 64GB of internal memory, out of which the user is left with around 50GB after running the phone for the first time. There is a memory card's socket as well – the slot is shared with one SIM card's slot. The maximum capacity is 128 GB.
Inside the device we can find the Snapdragon 630 CPU, supported by 4GB of RAM and Adreno 508 GPU. C10 does its job in everyday tasks and it’s hardware ensures a smooth work of the interface. Applications open without a delay, browsing longer pages in the browser or working on a few tabs is without any problems. The device reaches its peak capacity when gaming – Adreno 508 is a mediocre hardware for more demanding titles. The gameplay is not always satisfactory, animations take a long time to load, games lose frames as well. In addition, the device can heat up noticeably, reaching 40 degrees Celsius. Casual gamers can be satisfied with Sharp’s efficiency, but if you like to play in more demanding titles you need to buy other phone. For example Pocophone F1, which costs slightly more but ensures a much higher efficiency.
