Esta notificação continua aparecendo no meu telefone e não sei se é real ou não, lê:
"bateria foi infectada por 6 problema sério! Instale a bateria e todos os problemas serão eliminados."
This notification keeps popping up on my phone and I don't know if it's real or not, it reads:
"Battery has been infected by 6 serious problem! Install DU Battery and all problems will be wiped out."
It's a virus/maleware.
Sources that describe very similar situations:
It sounds like it's actually a really old scam (this may be a newer variant of it) Here's a story from 2011 that sounds like the same issue:
To give a view of why it is impossible for an app to diagnose much less than fix battery problems, a little background is in order
Battery houses a sensor/chip that is responsible for monitoring vital parameters like temperature, voltage, NFC etc. This information is conveyed to the OS through one of the pins that makes contact when the battery is in place (normally three pins, one being for this and other two for charging / discharging)
This information is conveyed to the battery driver portion of the ROM. These drivers cannot be modified permanently, even if your device is rooted, since these are initialised during boot up
Hence to identify state of the battery (other than the vital parameters) discussed above, you require a physical way of interacting with the battery. This should convince you that the claims made by the app are nonsense , aimed at attracting revenue
This is very annoying situation.
First thing to try is remove all cache files of those apps which has internet connectivity. On net there are many sites, those try to inject some malicious codes. This is first step to identify.
If first is not helpful, try to check the background running apps. Any suspicious app that you think, force stop that. See if it helps. If you find out any app which is on play store, you must contact and report this to developer.
You may also try to check all downloaded apps. May be something there.
