recently i finally changed my old cellphone and got a new smartphone and android was my os of choice
trying lots of apps i found on google play i found some very good and also some bad apps
what i have found really useful and haven't encountered problems using is:
airdroid, lets you copy, paste, delete files between other tasks on your sd card by opening your web browser on your pc, all over wifi, connected to your local network
es file explorer, a simple file browser but also has a image viewer and a audio player
led hd flashlight, it converts the led on your camera into a flashlight
mx player, vlc is not as good as it should be on android so mx is what you can use to watch movies on your smartphone
neoreader qr, fast and simple qr code reader
thalion brightness level, to control the brightness level on your screen and save some battery
3, a simple audio player with great sound quality and a good equalizer, better than the audio player that came with the phone
viber, free calls using your wifi connection to other viber users
colornote, if your smarphone doesn't have a app to take notes, this one is really useful
highway rider, fast and fun bike game, it is fun to crash and see the broken bones count

anyone has a app or a game that deserves to be tested on a basic smartphone? with no multicores cpu or big video card?
