Also, since Google Android is an open sourceplatform driving all Android phones, it could significantlyincrease the risk of hacking these devices. If thishappens, then locking mobiles as a security measure willbe a mockery.

This factor can be the biggest drawback ofAndroids.When you want to search any particular App and youhave placed wrong spellings, Androiddont correctthem. This can become an annoying factor for users

because you have to know the exact spelling if you wantto find an App. Google should correct this too ratherthan just including more and more stuff.
