A simple repair of distorted voice of my Amazon Echo Dot 3rd gen. The video describes the dismantling of the outer cover and the repair of speaker gasket.
just after the out of warrenty the same thing happened to me. I'll try to fix otherwise I'll order a new one and exchange the product with Amazon. because I brought in 7500 and now the price is 3249.
Thanks, The opening of power supply of echo dot 3 will start like the way i started off in this video, further to open the speaker and circuit board you can find on various videos already on youtube. You can check this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xrB6EhXGDqU.html
Would not recommend fevi quick because it becomes hard after drying. We need a glue which has flexible properties after drying. You can use fevi bond by fevicol.
If it's in warranty you can call Amazon customer care for fixing your echo dot. If not under warranty you have to get it repaired depending upon the defect the speaker has.
