Released in 2013 as a budget smartphone in three models/variants, the Idol features a 4.7-inch IPS LCD panel, 1 GHz dual-core processor, and an 8 MP camera. Includes models 6030A or OT-6030A, 6030X or OT-6030X, and 6030Dual-sim or 6030N.
What has probably happened is the contact point for the button may have broken off over time or something like that so email Alcatel about and they should fix it.
