Android Hidden Location Tracker

If you use a Android device google can track you via scanned and known wifi Networks without any connection! Android scans your area, shops, stores for public wifi networks, via LTE / GSM the OS verify the Data online at Google. As Result Google Maps sends you Popups to VOTE the last visited Places at Google Maps.

That’s all WITHOUT GPS and WIFI connected only LTE/GSM !

Purge Google Account! (disconnect!) and disable all unwanted Google Apps especially Uploaders (Backups) then go Android Settings -> Wifi -> Advanced Wifi Settings!

Disable the “local wifi scan” option switch at Android!

Remark:

  • No one knows which apps do run this tools at Standby Mode on Background!
  • To be safe remove the Battery of the Phones! or put it into a Metalbox (Copper Faraday Cage)

Android Browser Traffic Waste

If you use a Smartphone or Tablet be sure that the Browser like Firefox, Icecat Opera are not active at “minimize” mode, if the Website code uses a “auto” refresh code the Browser will endless load the sites on Background! This burns your Data Limit to zero..

Howto:

  • Swipe unused apps to Top of Screen!
  • Control by tapping onto the Square Button!
  • Use Data Traffic Control Apps default addon tool of Huawei

Android: Upgrade Downgrade Kindle Fire Firmware Bug

If you use a Amazon Kindle Fire 2015 (45$) Generation “Ford” or other Android Tablets,Smartphones you must know some MAJOR Informations about the Firmware Handling.

Amazon Kindle Fire 2015 Ford

  • If you were asked by the Fire OS or Android to “Upgrade” the Firmware OS, DON’T PUSH YES it without READING DETAILS! I prefer ALWAYS NO FIRST!
  • Use ALWAYS a SDCARD to hold the MAJOR Data of your Tablet, cause if bricked or damaged you can’t pull off the DATA!!!
  • Android Firmware Images INCLUDE not only the OS, it includes DRIVERS, and the MAJOR BOOTLOADER!! Cause Android Devices use no real BIOS!!
  • If you Upgrade, you can RUN into BIG TROUBLE! Broken Drivers like no WIFI connect, freezing Screens on Boot, or BRICKS like the “BLACK SCREEN of DEATH” which destory the Tablets cause you can’t reach the BOOTLOADER for RECOVERY MODE and SITELOAD the FIRMWARE again!
  • UPGRADES to bigger Version Releases like 5.1 to 5.3.X CAN’T be DOWNGRADED! Cause the DOWNGRADE don’t force overwrite correctly the BOOTLOADER, or leave the NEW BOOTLOADER untouched which can’t find the old KERNELS Names!
  • As MAJOR INFO you should know that the “adb shell tool” is a DEVELOPER TOOL which doesn’t ASK anything to confirm, if the Firmware File is wrong or damaged! It flashes without any testing and any protection check! YOU have to KNOW what you ENTER!
  • You can’t reach anything, if the Tablet is BRICKED and you can’t reach the RESCUE MENU MODE! Cause NAND Chips need a connect from adb shell tool to USB then to EEPROM Chip!
  • To be sure prevent the Tablet from reaching the Amazon Update Servers by blocking the Domains on a Blacklist at the Home Router
  • A pulling out the Battery, does often NOT HELP on Tablet! You often don’t need to open the Case for this try!
  • If you can, buy Tablets, without Bloatware, but with SDCARD Connector, with a more basic Android called “Stock” OS (have seen this on cheap No Name China Tablets)
  • Check the Internet Media for Hardware Infos which Hardware allow easy root access, some Manufacter allow this like Fairphones with special opened OS.
  • For Kids usage purge the Amazon Account on the Tablet, this prevent unallowed Setups
  • Android Firmware EEPROM Chips mostly glued onto the Mainboard, if the Firmware writing fails the device is a toaster.. no normal User can plug out the EEPROM Chips to flash them outside!
  • Opened Tablets can be seen here 

.. never change a running System.. if you MUST not..

Remarks:

  • If someone find a Solution to flash the NAND chips without the Recovery Mode then mail me please!
  • This Firmware Handling is the SAME on all Android or Embedded Devices like Openmips, Openwrt Routers ..

Android Browser: GNU IceCat the better Android Browser for you?

If you use Android on your Tablet or Phone, and you like to get back more privacy and security you should take a closer look at the GNU IceCat Android Browser:

Source: https://ftp.gnu.org/gnu/icecat/38.6.0/ (Outside of Play Store)

IceCat need NO Google Account and does not call home, install it and try it. I don’t wanne miss IceCat on my Cellphones

Handling is same like Firefox, cause it’s based on Firefox Framework, but offers more user access.

Update: Since Firmware update to 5.3.X the Amaz Developers seems to run a cronjob which enable the Ads again after some time! Try to block from calling home the Tablet via your Home Router Outgoing Firewall! Or if you use a DNS Server set the amazon update domains to 127.0.0.1 at the DNS Server Hosts File. Then the Tablet isnt able to pull commands and force ota Updates!

Block this Domains (or disable all Internet on the Kids-Rules of Firewalls):
