HTC Desire 510 

The vertical viewing angles are terrible, with the display exhibiting extreme distortion in brightness, contrast and color temperature when skewed.

At 321 nits, it's not particularly bright, and using it on a beautiful sunny day is practically impossible.

They are poorly exposed, washed out, and detail is smeared – really low-end quality.

A fixed-focus 5MP camera is very unimpressive in 2014, but its quality is absolutely disappointing.

The camera itself is poor, and being a fixed-focus unit, we'd say it's worse than the average 5MP cam you will find in low-end smartphones.

Unfortunately, these 0.3MP cameras are particularly good at making faces look their worst.

The audio app is better - it has a nice way of arranging and presenting your music in a clearly laid-out gallery.

Browsing menus, opening apps, and taking photos is very speedy.

Here's the best thing about it - when you aren't trying to play demanding games or browse heavy websites, it's fast.

Videos can be shot at a maximum resolution of 1080p , with all the colorful filters applied to them as well.

These features aren't very impressive, as one simply slows down the video, making it twice as long as the original, and the other basically speeds it up.

In our tests, it failed to play DivX and QuickTime-encoded video files, but it played H.264, MKV, MPEG-4, XviD fine.

The phone is pretty slow to charge, as it gets to a full load in 3 hours and 27 minutes when using a charger with 5V (1.5A) output.

But in our battery test, it managed good 6 hours and 59 minutes of on-screen time before it expended its 2100mAh battery.
