ES File Explorer phones home if you give it root access

ES File Explorer is one of the best file managers for Android. In addition to managing your local files and folders it has a built-in ftp client (but no ftp server), does bluetooth file transfers, connects to Samba servers, talks with Dropbox (and lets you transfer entire folders, which the official Dropbox app won't do), unpacks zip and rar archives, can put shortcuts to files on your home screens, and...

...it works as a root explorer too.

The root explorer function of ES File Explorer means that you don't need apps like Root Explorer (which is not free) or File Expert (which has an inferior user interface).

The root explorer function of ES File Explorer used to work on a few ROMs only, but a recent update makes it work on all Android phones.

So far, so good. But there's a catch. ES File Explorer used to be a very well-behaved app that only went online when you told it to go online, e.g. when connecting to an ftp server or a Dropbox account. But when you enable root access ES File Explorer goes online everytime it runs, and it doesn't tell you why it goes online, what data it sends out, and how you can switch this suspicious behaviour off.

I'll give the app the benefit of the doubt for now. It probably sends out statistics to tell the developer if the root explorer code works. But maybe it does something else? More info from the developer would be appreciated, and an off switch for non-essential online activity is a must. Especially for an app with root access that can read all your files.

Of course you can stop ES File Explorer from phoning home with DroidWall, but then you miss out on its ftp and Dropbox features. You can also disable root acces for ES File Explorer (it doesn't go online then, unless you connect to a remote file server) and use File Expert when you need root access to play with your system folders.

Backup your old apps, because newer is not always better

There's a site called oldversion.com with old versions (duh!) of programs for Windows, Linux, and Mac.

Unfortunately oldversion.com doesn't have old versions of Android apps. Maybe they'll have 'em in the future, but for now the place to get older editions of Android apps is on Android forums of ill repute.

In a perfect world we could simply reload old app versions from the Android Market. Idea for Google: add a "revert to previous version" button to the Market. But the Android world is far from perfect. Apps on the Android Market come in one flavor only: the newest version. Even if the newest version doesn't work for you.

Why be old skool?

There are many good reasons for using an older version instead of the latest edition. The new version of your favorite app is too bloated to run on your underpowered vintage Droid. New versions may ask for more permissions than you want to give them or come with new obnoxious advertising (the APNdroid disaster comes to mind). Or they introduce new bugs that crash your phone. And sometimes good apps are simply removed from the market by its maker or by Google.

Some examples:

Google Maps recently added two experimental features: public transport navigation and map downloading for offline use. Sounds great, but the new version froze, crashed, and sometimes the only way to get my phone running again was to pull out the battery for a rock-hard reboot. Reverting to the previous version means no new features for the time being, but without a backup of the old version I wouldn't have been able to use Google Maps at all until Google irons out the bugs. Later updates came with fresh new bugs, like the mysterious disappearance of your contacts from Google Navigation.

Skype recently added video calling. Great for cyber sex, but useless if your phone doesn't have a second camera on the front. And anyway, video calling gets old real quick. Years ago I played with video calling on my ancient Nokia, but then the novelty wore off and now my front-facing camera is lonely and neglected. Of course I could have kept the new Skype version and ignore the video call options, but it also came with a new dumbed down interface that is a step back from the good old tabbed layout. So for the time being I keep the old version.

GO Launcher EX is a great Android launcher. Unfortunately it suffers from featuritis. New versions add features and clutter of little or no value, and stability suffers. Some older versions of GO Launcher EX outperform some new editions.

And then there's Facebook. In my opinion its mobile website is way better than the app, but the app has one feature that I like: the Facebook phonebook folder. This folder contains all your Facebook friends who're stupid enough to trust Facebook with their phone numbers. It's an easy way to store the numbers of your fellow Facebook friends and enemies without cluttering your stock phone book app. But only if you stick with Facebook 1.5.2, because this useful feature was removed in later versions.

Go to a museum, or make your own

Since there is no reliable repository of older app versions you'll need to take matters in your own hands. Titanium backs up your app settings so you don't need to go through all the configuration screens again when you reinstall. MyBackup, ES File Explorer, Astro and other apps can also back up your APKs. For most features you'll need a rooted phone.

• Titanium Backup
• MyBackup
• ES File Explorer

If you trust forums like iPmart, OPDA, and Noeman, you can download old app versions from their sites. These forums are like a museum of vintage app versions. Just keep in mind that there's also quite a bit of questionable stuff over there. Of course some people might consider that an advantage.

LBE Privacy Guard update leaves your notification bar alone

LBE Privacy Guard helps you tame your apps. Downloaded something that wants to check your whereabouts for no good reason? Just tell LBE to deny access to your location to that app. Now you can use GPS without worrying about half the planet tracing your footsteps.

You can also control which apps can read your SMSs and which apps don't. Same for other private information like your phone number, IMEI, contacts, etc.

LBE Privacy Guard shows a warning when apps try to do something that may violate your privacy or cost you money. It also keeps detailed and well organised logs to let you check what your apps are up to when you turn your head. Permissions that you can control:
- making phone calls;
- sending SMSs;
- reading your SMSs;
- reading your contacts;
- reading your call logs;
- getting your location (by GPS or from networks);
- identify your phone by IMEI, IMSI, phone number, or SIM card ID;
- internet access.
It's up to you whether you grant or deny permissions. LBE can remember your answer so you don't get flooded with security warnings. You can also tell it to ask you again if you're not sure that your answer is the right one. Exceptions: no prompts for internet access and phone identification, only an allow/deny switch in the settings.

The new LBE Privacy Guard version improves blocking of outgoing SMSs for phones running on Gingerbread (Android 2.3). The user interface got cleaned up a bit, and you can now hide the annoying Vodafone-like icon that used to waste space in your notification bar when LBE was running. At first glance that may seem like a tiny cosmetic issue, but just think about how often your notification bar is looking at you (or the other way 'round).

Apps may refuse to run or even crash when they don't get the permissions they expect. It's a good idea to block permissions one by one so you know what's wrong if an app stops working.

LBE Privacy Guard is all about safely running apps that you don't fully trust. If you don't trust LBE, just tell DroidWall to keep it offline. It's a good idea to use LBE together with DroidWall, because internet is either on or off with LBE. DroidWall lets you fine-tune internet access so you can use different permissions for Wi-Fi and mobile data.

Google Maps update adds downloaded maps for offline use, public transport navigation, and new bugs

Offline use of Google Maps used to be limited to a narrow strip around precalculated routes, but Google Maps finally learned that map browsing without a live internet connection is a useful thing. New in Google Maps 5.7: you can now choose map areas to download. Hit menu/more/labs/download map area, long-tap a spot on the map, and the surrounding area is stored on your memory card as a 15x15 mile block with the tapped spot in the middle.

Map limits

Downloaded maps expire after 30 days, after which you'll have to redownload them if you want to keep 'em. A reason for the time bomb may be that the maps are spotted with landmarks like shops and banks and other businesses that advertise on Google. Of course you'll need the latest sponsors on your maps to keep the bean counters at Google happy.

You can't make the downloaded areas bigger, but you can download multiple 15x15 mile blocks. Unfortunately there seems to be a limit of ten blocks, so forget about loading your entire country on your memory card unless you live in Luxemburg or Andorra. But it's better than nothing, and maybe Google will lift the ten block maximum later on. If Google doesn't drop the limit I'm sure some smart hackers will find a way to bypass it.

Maps are stored as vector graphics so they take little storage space. A 15x15 mile area needs about 3 to 7 megabytes. That's a big advantage over competing free offline map apps like Locus which store maps in a bitmap format that eats gigabytes for breakfast:
- Amsterdam plus suburbs with Google Maps: 5 MB.
- Amsterdam with Locus: over a hundred megabytes, and that's without the closest zoom level and no suburbs either.
On the other hand, Locus lets you download maps from more sources than just Google.

Public transport

Google Maps now also does public transport navigation. With only 400 cities covered worldwide it may not available where you live, but it's a promising start. Google calculates routes and transfers, gives a rough estimate of how long your trip will take, and it can vibrate to remind you that you've reached your destination or have to switch to the next train or bus. It needs to see GPS satellites for those reminder vibes, so it won't work in the subway. And don't forget to double-check the suggested routes to make sure that Google doesn't make you take the long way home.

Note that you can browse maps offline, but route calculations still need internet. Google still has some tricks to learn from the fully offline Nokia Maps.

Bugs

Unfortunately the new update introduces some new bugs and other annoyances.

Google Maps loads the network location process as a background service that won't go away. Kill it and it instantly resurrects like a phoenix, even when you disable network location in the settings menu. Workaround: go to the Maps entry in the Android settings app and tap "force stop." Maybe Google will see the light and make the background service only run when needed in a future update? Yes, I know that previous versions had the same bad manners, so a fix is long overdue. Especially now, because...

...there's a bug that makes my phone run like a snail on tranquilizers or even freeze when I run Google Maps 5.7. The sluggishness persists even after I kill the maps app, so I'll blame the network location background service that refuses to go away (killing it by "force close" makes my phone run smooth again). Processor overload or memory leak? Whatever it is, Google needs to fix this. There are many others who reported the same issue in the Market comments. The bug bites different phones. It makes Google Maps 5.7 totally useless for me, so I had to go back to version 5.6.2.

This bug could bite you too, so don't update Google Maps (or any other app) until you made a backup of a version that works. Apps like Titanium and MyBackup can save the old version for you, so there you have another reason to root your phone if you didn't root it already.

While the coders at Google are busy ironing out the bugs maybe they can also repair the auto-update checkbox in the Android Market? If you allow the market to auto-update Google Maps you can't switch it off anymore (unless you use a third party trick like the market auto updates tool in Titanium). A fix is urgently required because force-feeding updates is totally wrong.
