Most of this article doesn't only apply to Telegram+ -- it just happens to be an example that got a lot of coverage elsewhere, with many authors or commentators putting the full blame on Google, Telegram, the Telegram+ developer or even WhatsApp Inc (eh?). In this article, we'll try to look at the different aspects to provide a clear view of what actually happened, and what can (and hopefully will) improve with regards to developers in general and the Play...
Backup and Restore EFS, MODEM, and TA Partitions with Just a Root App
New Android devices have some crucial data stored on normally inaccessible partitions. Samsung users certainly know about EFS and its importance, and Sony users value their TA partitions instead. Much important data is stored in these places, and accidentally wiping these partitions can lead to many problems like loss of network connectivity or disable things like Bravia Engine and OTA updates. We previously talked about tools for Sony and Samsung devices that can backup these partitions, but they all require a PC (and Windows) to work.
This is now no longer an issue, thanks to XDA Forum Member pyler, who created a tool to backup those partitions to your SD Card or internal storage really easily. Naturally, this app also gives you the possibility to restore the backed up data when something goes wrong.
The application automatically detects your device and backs up the necessary files. To work correctly, your device must be rooted and be on at least Ice Cream Sandwich. But be warned that messing with your EFS, modem, or TA partition can turn your phone or tablet into plastic brick and void your warranty. The chance of breaking something is low, but it’s better be safe than sorry.
More information regarding supported devices and the application itself can be found in the original thread. Go there to learn more and provide some feedback to the developer.

Ever since custom recoveries and roms became popular, nandroid backups have been the fall back method for all android enthusiasts, irrespective of their confidence levels. They allow easy backup and restore in case things go wrong, which happens invariably when a modification is being tested. With that being said, how relevant are Nandroid Backups to this day? Back in 2011, when the world of Android was being awed by the likes of the Samsung Galaxy S2, a little modification made its appearance...
While HTC's latest flagship brings many new features, the aesthetic design of the device remains largely untouched in comparison to its predecessor. Many Android enthusiasts throughout the community were expecting a large redesign of one of the most beautiful handsets ever released, but what we got is something more along the lines of an 'HTC One M8S". So this begs the question, is the M9 worth the upgrade if you already own the M8? Current HTC One M8 users chime in and let us know your thoughts.
