Are there any severe/critical security vulnerabilities in Li= nux kernel 4.19.191+ that will allow government-sponsored or state-backed h= ackers or Advanced Persistent Threats (APTs) to take over absolute control = of my brand new vivo mobile phone? Can I download, compile and install the = latest Linux kernel 6.5.4 from sources on my brand new vivo mobile phone by= myself? I would like to know how I can do it. >=20 There are Android Security Bulletin listings on [1], with vivo-specific bulletins can be found at [2]. For building kernels, you can follow official Android guide [3]. Or you can also visit XDA forums [4] where people posted their own custom kernels. But usually your vendor (vivo) takes care of kernel updates anyway. > I have decided to buy this vivo mobile phone because my Samsung Galaxy A3= 2 5G mobile phone has now become extremely slow in performance and lags lik= e hell. Maybe too many apps were installed. What are these apps besides built-in ones? > Opening and using apps is now a slow and painful experience. The phone ca= mera is even worse. Taking a photo or selfie takes 2-3 seconds. If you move= the phone by a bit before the 3 seconds is up, your photo or selfie will t= urn out very blur. So you need to set a timer of 2 seconds when you take a = selfie or photo. Taking videos with the phone camera is also very laggy and= choppy. The recorded video will turn out to be choppy. >=20 What is your Samsung phone specification then? Thanks.
