What concerns me most is the updates and patches. Most ODMs deliberately ship these phones with last gen Android, then maybe update to a "new" gen two years later when that one has already become far obsolete. On top of that, bugs and security patches are close to nonexistent, even from multi-global corps like Lenovo and Xiaomi.
As long as Google is loose with Android unlike the way Microsoft handles Windows, the price we pay for budget phones will always be just as expensive as flagships'.
i would happy to see there is 10000mah phone in market. its still far better than i carry the power bank . all in one is the only convienant way for us.
