Features, Performance, and Reviews for the LG K40
The camera function of LG K40
The LG K40 has a 16 MP main camera that lets you take photos and videos in a quite high resolution. You may be a little dissatisfied with it in some situations, for example when you want to capture scenery in very high resolution or print out beautiful photos, but this should not be an issue you run into very often.
The LG K40 comes with a 8 MP pixel camera, which is a standard level. It's perfectly fine for selfies, but may be not as satisfying if you wish to take photos of large numbers of people, or make printouts.
The battery performance of LG K40
The LG K40 has a relatively large battery with 3000 mAh. The LG K40 has a good battery life compared to other smartphones. You won't feel stressed even if you spend all day surfing the web or on Twitter and you can also watch videos or play games on the go without having to worry too much about the battery. If you watch videos or play games for too long, however, you might want to watch your battery a bit.
LG K40's size
The LG K40 is 2.8 inches (71.9 mm) wide, 6.0 inches (153 mm) tall, and 0.3 inches (8.3 mm) thick. I can just barely use it with one hand, so it may feel big to some people. In the case of the LG K40, it weighs about 144 oz (144 g). The weight is such that it's hardly noticeable even when using one-handed. However, some people may find it tiring to use for long periods.
In giving an overall rating to the LG K40, while it may be slightly difficult to hold, it shouldn't be much of a problem when considering its general strengths and weaknesses.
LG K40's screen
The LG K40 has a 5.7 inch screen. The smartphone has a large, impressive screen, which allows you to enjoy photos and videos to the fullest. It is also very good for writing business documents and doing other work.
The resolution of the LG K40's screen is pretty much standard. It shouldn't be a problem for normal use, but it might prove to be a bit dissatisfying for those who wish to better enjoy their photos, videos, or games.
The CPU performance of LG K40
The LG K40 has an extremely high processing power of 2.0GHz×8(OctaCore), so it can smoothly run any app out there with ease. Its performance ranks among the top-class of all smartphones released to date. It's well suited to running even the most demanding of 3D games with ease.
The LG K40 has 3GB of RAM, so it has plenty of space. In rare cases this amount of RAM might not be sufficient, but there shouldn't be too much stress on the machine with this amount.
The LG K40 has the overall operating speed of a high-end smartphone, so it will hardly ever cause you trouble. But you might need to be careful when using heavy apps like 3D games a lot.
LG K40's storage capacity
The LG K40 has 32GB of data storage, which is plenty for taking photos, but for people who frequently shoot videos or have lots of games installed, this may not feel like enough space.
Since the LG K40 is compatible with SD cards, you'll be able to easily expand your storage capacity; you won't need to worry about how much internal space it has.
Overall assessment of LG K40
The LG K40 is a high-performance smartphone. You're not likely to experience any inconvenience in general use.
