Security Research Labs tested the firmware of 1,200 phones, from more than a dozen Android phone manufacturers, for every Android patch released in 2017.
In the age of cyber attacks, smartphone users rely on manufacturers to keep their gadgets secure with regular updates.
However, according to German security firm Security Research Labs, not only do some Android phone makers fail to issue updates regularly, they have also been misinforming users by lying that their phones' firmware has been fully updated even when they have skipped a few security updates.
