    Today I had some time and I decided to create a small application for a screenshot. Always makes me annoyed press power and vol + and etc., to make a screenshot, because I made an application that make screensot when shaking up&down the device, and when I want a screenshot simple just shaking ;). Maybe someone will be needed so I decided to share it.*

    Application to work need android 4.0+, ROOT and BUSYBOX!!!
    Screenshot will be saved on /sdcard/Shakeshot .
    For all questions, download and others stuff please contact me and follow on www.android-tech.rocks thanks.

    3g dongles / umts modem / internet surfsticks.... Work!! USB OTG (directly!)

    after some failed attempts with ppp widget 2, involving different 3g dongles and a powered hub i finally got 3g working!

    i used PPP WIDGET 1 with the classic 3g dongle: an old Huawei E160, and a newer model : E173u
    (most newer Huawei should work too! ) no hub was needed!

    the Huawei modems have a built in emulated driver cd for Windows and that's why the need additional software to be switched from cd mode to modem mode, our tablet / Android however doesn't recognize the cd filesystem and says "damaged usb storage"... which is no problem, it's normal!

    the automatic recognition of the new ppp widget 2 failed, but the older widget 1 has a manual mode: select manually choose device!

    how to set up ppp widget 1 on B1-730hd :

    1. get ppp widget1 from playstore (free)
    2. put the widget on a startscreen (necessary before plugging the dongle!)
    3. plug the modem in... wait for the "damaged usb storage notification"
    4. the system asks which app to use as a standard.... select ppp widget1
    5. disconnect device
    6. go to configuration button (of widget)
    7. enter apn, username & password
    7b. depending on your sim & carrier : enter pin code if you use that and enter ip and port of needed (if it failes to connect with "connect script error" you need it) (i had also to enter ip adress : port to get it running)
    8. select manual device selection (tap on icon mode)
    9. close settings and plug in device
    10. tap on the icon (left ppp symbol on the widget) and chose your modem: Huawei xyz...
    11. see if the status led changes blinking color (from green to blue) = pin unlocked, network ready
    12. the connect button is not longer greyed out... click it.... and wait

    if the led stops blinking dark blue and turns light blue (permanently) you made it!
    if not : open configuration and see LOG, most likely your apn, name, pwd, ip etc are wrong....

    have fun with direct access to 3g on the tablet - no need to wifi or Bluetooth tether anymore if you own am old Huawei E160 (more modems should work, but i haven't tried) (no powered hub needed, but use one of you want to save battery...)
    working devices :

    Huawei E173u (7Mbit max., Dual antennas, balanced against interferences) i recommend this, good signal and fast...
    Huawei E160, (3,6Mbit, single antenna and sometimes bad signal) use it if you own one, but buy the E173u instead (signal boost, interference minimization, good signal)
    4
    calm down people, we don't need this to live or make money... but sometimes we need some help to help, Happy 2015 to everybody!
    Very thanks to @vampir74 & @social-design-concepts, happy new year to you guys!
