The size and weight of the LG L70 are fine. The sound when phoned is good, the called party sees a problem-and one even understands the called party clearly and without interference. Even the "phonebook" can be used without much searching and trial and error.
The camera can be quickly and easily make good photos. If it is to go for a motive fast times, the side button can be pressed and even the camera is activated. This also works in standby mode.
The WiFi connection for the Internet works great and without disturbance. Whether, for example, surf, listen to audiobooks or watch videos. Everything works fine and with good sound and picture. WiFi can quickly and easily switched on and off, if you want to use the Internet rarely.
The Knock Code (knock in an order set by the user on the screen to unlock the device) works in my experience, well as long as the user has warm hands. As I have often cold hands, I have to enter the code usually several times or knock it till the LG L70 reacts and unlocked.
Conclusion: Recommended and user-friendly entry-level smartphone.
