Wow.. That's a great achievement bro. My MI 3 lasted for just 13 months and didn't boot up. I thought MI provided "Time Bomb" within their devices so that, the device will broke exactly after warranty period. But Poco F1 (I bought for that great feel of the Kevlar back) is still running great.
Brands use this strategy to keep the phone prices in check (They get money from the bloat apps' Co). Too bad, even big Company like Sammy is also guilty of this strategy in their budget and mid range segments.
That's why I love Motorola and Google phones. Both are having clean UI with zero ads. Further Motorola never gives update and so no fear of buggy updates
. Google sells their phones already with lots of bugs and takes their sweet time to fix them one at a time with one update each.
