This is a significant matter that firms should address, because I am confident that the hackers are intruders and are related to the companies in some manner, as they cannot obtain the exact number of devices affected by the malware attack.
Although Android phones are good at first, I urge that consumers stick with well-known and trusted brands like Samsung since I am confident that their security will be closely maintained and such concerns will be rare.
That is to say, you'll find this sort of bad firmware in the cheaper end of the Android ecosystem, and sticking to bigger brands is a good idea though not necessarily a guarantee of safety.
To avoid such attacks, we must exercise extreme caution, avoid using cheap mobile Android devices, and purchase our devices from a reputable provider.
