Unable to switch on first try and light flicker blue once

So i just bought my bedside lamp YLCT01YL for a couple of months. I usually use it from night to morning… problem comes when i try to switch on at night time again after around twelve hours off time… it does not turn on the first time when i press the on button, on the lamp or on my phone… it turns on after 3-4 tries… sometimes it does not directly switched on, it flickers blue light once then next try on… i’ll try to record a video later… anybody seems to understand where the problem lies? Aftersales service where i bought it from is helpless
