Connect the phone to the PC via the USB cable.Remove the SD card from the phone and enable the USB debugging option on the phone. Care must be taken not to miss any of the steps while rooting, or the phone may become unusable. You can root your phone by following the steps below. In order to remove apps, your phone must be rooted. This guide will tell you what you need to do to remove these pre-installed apps and clear space on your phone. However, some of these apps may be unwanted and may just be occupying space on the phone which might otherwise be use d to store desired apps. IntroductionĪll phones come with pre-bundled software to help users access some of its features. Nothing at all needs to be stored in the database, while being on par with security with the solutions I'd been considering.In this guide we will tell you what you need to do to remove pre-installed Android apps on your Android phone. The smart way to do this is to include in the unsubscribe link a cryptographic signature of the user to be unsubscribed and what they are to be unsubscribed from. However, even this would not eliminate the problem entirely, as this would really just be security through obscurity, and anyone with the URL could tamper, and in the end the main defense would have to be that most people aren't so bored as to tamper with other people's email preferences.Īre there any other alternatives I've missed, or issues or solutions with these that anyone can provide insight on? What are best practices in this area?Įdit: Here is the alternative I missed for anyone coming across this later. This could be mitigated somewhat by ensuring that the identifier is really difficult to guess.įor the once per user identifier approach, I was considering generating the identifier by passing a user's ID through some type of encryption algorithm, is this a sound approach? For the per-email identifiers, perhaps I could use a user's ID appended to the time. In contrast to above where I would need one of these identifiers for each email, this would only need one identifier per user, with no generation or other action required on sending an email.Īll of these raise security issues, and they could potentially be used by people to tamper with others' email preferences. However, am I incorrect in thinking that either of these would require me to generate and permanently store a unique identifier in my database for every email I ever send, really complicating email delivery? Without that, I'm not sure how I would be able to uniquely identify a user and a type of email in order to change their email preferences, and this identifier would need to be stored forever as a user could have an email sitting in their inbox for a long time before they decide to act on it.Īlternatively, I was considering having a no-login page for managing email preferences. The later would probably require me to break convention and make changes to the database in response to a GET on the link. I've looked into list unsubscribe headers as well as creating some type of one click link that would unsubscribe a user from that type of email without requiring login or further action. However, I'd like to also give users an easy way to unsubscribe directly in the emails they receive. Users have accounts, and when logged in they have access to a setting page that they can use to customize what types of emails they receive. I'm working on a website that features many different types of emails.
