While I have never experienced this serious issue, and I agree with the need for much better quality control, the fact remains that the standard one year manufacturers warranty is the "real" issue here! Now for a bottom shelf phone a year is sufficient...mid-range phone should get AT LEAST 2 years or maybe even 3...and a 1000 dollar or more flagship should get at least 4 years and possibly 5!
Having to buy an extended type warranty might be warranted for those who want to keep their current phone for a long time, but this should NOT be necessary!
Hey OEM's here's a BETTER way to sell more phones...stop promising 7 years of updates that you KNOW very few people will ever take advantage of...but instead offer a real solid warranty and watch your sales go much higher...and make it a transferable warranty!
