Remove Deleted MMS and SMS from Logs for Added Security on the AT&T SGS II

There is no such thing as too much security when it comes to mobile devices. There are ways around pretty much every security method out there—from using fingerprints to figure out pattern locks to programmers creating malware that doesn’t fit into anti-virus definitions.

With that said, how many people knew that SMS and MMS messages were stored in logs and could be viewed, even after they’re deleted, by anyone who picks up their phone? It’d be safe to bet not many. And while it’s not a security risk per-say, it’s definitely a chance to invade privacy even when one thought their privacy was being protected. This is a problem that XDA Forum Member jeboo is looking to solve for at least owners of the AT&T Samsung Galaxy S II.

What the modification does exactly is edit the mms.apk to skip the portion of code that puts the MMS or SMS into the log and since they stop being put into the log, people can stop using that method to read your old SMS and MMS messages. In the words of the developer:

Note that with this patch the log entries are never saved. So if someone gets a hold of your phone and tries to dig them up, you’re fine!

The application of the patch requires some apk compiling and de-compiling skills. So if you’re not quite brushed up, it’s recommended that you do so before attempting. And, as usual, don’t forget to make a backup before changing anything, just in case.

For additional information, the full instructions and discussion, check out the original thread and get those text messages gone for good.

Watches: Luxurious Frivolity vs. Humble Practicality

Smartwatches still have a lot of growing up to do. Not too long ago the latest Canalys figures revealed a rather disappointing outcome for 2014, something we covered with the ultimate conclusion that, once again, smartwatches had no year. The direction of smartwatches is unclear to even the biggest OEMs, and with every new option there seems to be polarizing dissonances from what people and OEMs want and what they both think they want. We've documented many of the reasons as to...

Do ISPs Abuse Their Power?

Every day, the majority of us use the internet through several different internet service providers, but what we may not think about whilst using this service is how much control these companies have over our experience. AT&T recently launched their rival to the Google Fiber service and subsequently looked for a way to further monetize on their offering. For an extra $29 on top of the $70 monthly charge, you can buy your privacy back from them. Otherwise expect online adverts...
