The processor performance is okay, my games and videos not stutter. The quality is okay.
The 8 GB Flash memory are already shrunk with operating system and preinstalled apps to approximately 3.7 GB, but I was able to install a few apps and a micro SD card can enhance the memory a lot. Nor can some apps move to the memory card.
For this smart phone, you need a mini - SIM card.
The camera is also fine, in daylight the quality of images is good, but in the frame, as you would expect from an 8 megapixel camera. The sharpness leaves something to be desired. For important recordings you should use a proper camera.
Unfortunately, the touch buttons for Back and options are not illuminated when I was previously used the Samsung Galaxy SII, I already miss this something. Likewise, the arrangement of sensor rewind button bugging me left and right key sensor options- something because I'm used to it exactly the other way around from Samsung.
Make and receive telephone calls is okay, you can hear well and is well understood. The voice is clear and it roars not crackles. I had not added any disconnections. Typing on the keyboard is working properly.
The sound when listening to music is fine.
Overall, I am satisfied with the LG L90.
