Is there any heat issue with Micromax Canvas Doodle 4?

Well, it depends on how you use the device. Almost any phone will heat up a bit when used for prolonged hours with resource intensive apps and games. However, Canvas Doodle 4 has not been observed to suffer from any kind of abnormal heating issues.

Micromax Canvas Doodle 4 has a 1.3 GHz MediaTek MT6582M processor with Mali 400 GPU but nowadays the main issue is heating problem. If you play heavy games then it will heat up or if you will do heavy multi tasking then it also heats up but I am not fully sure as these are only predicted and no official news is yet announced.

@Kunal, though the device has not been released, reputed review sites get hold of review units and the inferences are drawn from those units as a preview.
