Tech giants Samsung and Apple have reportedly issued alerts about faults on some of their phones.
According to The BBC, Apple is facing some problems in some of its iPhone 5 because of a faulty sleep/wake button whereas Samsung is experiencing a 'camera failure' in some of its devices.
Both the companies have started a replacement programme for their faulty handsets.
Samsung said that they have found the cause of the fault and ensured that it will not happen again in future.
Meanwhile, Apple said that a small percentage of iPhone 5 handsets were affected, and the sleep/wake mechanism will be replaced free of cost.
Replacement programme for the above will begin on 2nd May worldwide.
