My   DIY  15.6 inches Android  Smartphone 


As of today , 8th.November2019 , there is no sign of a  15.6 inches  Smartphone ,  there is no sign of a  15.6 inches  4G  Smartphone  in the market .  Why the hardware/software  manufacturers are not making  15.6 inches size Smartphone ?
  
Maybe it is because there is plenty of  15.6 inches Android Laptop [ 1 ] and plenty of  15.6 inches  Android Tablet [ 1 2 ] in the market , so , there is no point of making a  15.6 inches  Android Smartphone .
 Or maybe it is because  a  15.6 inches  Android Tablet is  just like a big Smartphone , it is just like a 15.6 inches  Smartphone , so , what is the point of making a  15.6 inches  Smartphone .
  
I guess , if somebody want a  15.6 inches  Smartphone , or if i want a  15.6 inches smartphone, do yourself a favour , do myself a favour ,  buy a  Tablet , buy a large Tablet ,  buy a  15.6 inches  Tablet ( that have a diagonal screen size just like a   15.6 inches  Laptop ) just like the  SAMSUNG Galaxy Tab S9 Ultra  5G  which can make phone calls and answer phone  calls just like a  5G  Smartphone , and it  will look like a  15.6 inches smartphone , and it will  behave exactly just like a   15.6 inches  Smartphone(even though the  SAMSUNG Galaxy Tab  S9 Ultra  5G  has a  14.6 inches screen size . ).  Hopefully , the next version of  SAMSUNG Galaxy Tab S9 Ultra  5G  ,    SAMSUNG will maximize the screen size to 15.6 inches .   With that 15.6 inches form factor , with that diagonal screen size of a  15.6 inches Laptop , with that diagonal screen size of a  15.6 inches Tablet , the  15.6 inches version of the   SAMSUNG Galaxy Tab S9 Ultra  5G     can serve as a Laptop , it can serve as a Tablet , and above all it can serve as a 5G smartphone , which makes this machine a true and a real  [ Laptop/Tablet/Smartphone(ALL-in-ONE) ] machine or a  3-in-ONE  machine .  

So , I guess , there is no Business Sense for a   hardware/software   manufacturer  to make a  15.6 inches  Smartphone  when the  SAMSUNG Galaxy Tab S9 Ultra  5G  already fits the description .    

As of today , March 2024the   SAMSUNG Galaxy Tab S9 Ultra  5G  is still too expensive for the majority of consumers . Whatever the reason is  as to why  a    hardware/software        manufacturer  is not making  a    15.6 inches   Smartphone ,  I decided to make a simple  15.6 inches Smartphone myself   for my personal use .     It is not a long and expensive process , it is not a long and lengthy and complicated process,   compared to a  6 inches or 7 inches  Smartphone coming out from  a   high-tech  Smartphone factory .

   

 The DIY (Do-It-Yourself)   15.6 inches  Smartphone is not                 high-tech,  it is just a plain simple good old  15.6 inches  Smartphone whereby  a  Senior Citizen like me can use daily .  I guess it is one way or the only way that I know , to the best of my knowledge , how to make my    phone/smartphone     image bigger or  make my cellphone screen size  larger .   By making use of whatever hardware resources that is available today ,  I assemble them together to make it look like a  15.6 inches  Smartphone which can also act as a Laptop (when connected to a  Wireless/Bluetooth keyboard and a Wireless/Bluetooth mouse , the  15.6 inches Smartphone  can  be like a  15.6 inches Android  Laptop  and  can work like a   15.6 inches  Android Laptop )   and which can also act as a Tablet .   The 15.6 inches  Smartphone ,  or the 15.6 inches  Android  machine , I made  myself , does not look nice , glossy , or shining if compared to a ready made  6 inches or  7 inches Smartphone which came out from a high-tech Smartphone factory ( which is a long , lengthy , complicated and expensive process ) .





 Basic requirements are :

1.    SAMSUNG Galaxy Note 9 ( I bought this machine second-hand)
       [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ] [ 6 ]  

2.    15.6 inches  external  " Touchscreen "   monitor .  There are many  15.6
        Monitors to choose from   but I pick the    15.6 inches   "Touchscreen"  External
        Monitor made in CHINA .  Regretly (I regret very much) , I
       bought  a  15.6 inches   " Touchscreen "      External  Monitor that does not come with a
       built-in battery .  I   should have bought  a   15.6 inches   " Touchscreen "
      External  Monitor       that come with a  built-in battery so that I can carry the
      15 inches    "Touchscreen"   External  Monitor   everywhere
     without worrying to connect it to a 240 Volts AC 
        Wall Outlet .

 3.    DC Power Adapter (12 Volts DC) to power the 15.6 inches  external  " Touchscreen "
          monitor . This Adapter come along with the purchase of the  15.6 inches External
          " Touchscreen "   monitor .  One end of the Cable goes to the  240 Volts AC  Wall
          Outlet  and the other end which is  a  USB 3.1 Type-C female goes to the  15.6 inches
          external  "Touchscreen"  Monitor .  

4.   USB 3.1 Type-C female to  USB 3.1  Type-C female  Cable .  One end of the  USB 3.1
        Type-C  female goes to the  USB 3.1  Type-C  male  of the  SAMSUNG
      Galaxy Note  9  and the other end of the  USB  3.1 Type-C  female
        goes to the  USB  3.1  Type-C  male  of  the  15.6 inches
        " Touchscreen "External  Monitor     .   This   
        charge  or is bundle  together  when I bought  the    15.6 inches  external
        "Touchscreen"  portable monitor .  The  diagrams ,  wiring and connections are shown
         below :


The picture above is for illustrative purposes only .  After both ends of the   USB 3.1  Type-C ( female )  cable is connected and power ( 12 Volts DC ) is given to the  15.6 inches                " Touchscreen "    External   Monitor by connecting the  monitor to a  Wall  Outlet ,  and after switching on  the  SAMSUNG  Galaxy Note 9   ,  automatically we get into    "Screen Mirror Mode"  , that is , we will get  a   " mirror image "  of the   SAMSUNG Galaxy Note  9   Smartphone  displayed  on   the  15.6 inches    "Touchscreen"  External   Monitor .    It is Plug-And-Play at its best ,  no lag ,  no slowdown , no  stuttering ,  no   software/drivers   are required .  Since  the   15.6 inches    "Touchscreen"   External Monitor is a touchscreen device , we can Tap the screen , we can Pinch the screen , we can Resize the screen ,  just like an  Android Smartphone , so much so ,  it is just like having a  15.6 inches  Android Smartphone , it is just like having a  15.6 inches  Android Tablet ,  it is just like having a  15.6 inches  Android  Laptop .  It is just like having a   [ 15.6 inches  Laptop/Tablet/Smartphone(ALL-in-ONE) ]     machine .

   


5.   12 Volts DC  Battery  [ 1 ]

6.   1000W DC to AC Inverter  [ 1 ] 










 To make the   15.6 inches "Touchscreen" External                Monitor   look/appear/behave     like a  15.6 inches  Smartphone , we have to  give the  15.6 inches  "Touchscreen"  External Monitor some mobility , just like an Android Smartphone . This is what I did : 


1.   I carried  along the 12 Volts DC battery   1 ]   together with the  1000W
      DC to AC Converter  1 ]   inside my backpack  and carry them
      with me everywhere I go .





"Screen Mirror Mode"  Experience _ My experience  in   "Screen Mirror Mode" (without  SAMSUNG DeX) on my    [ DIY  15.6 inches Android  Smartphone ]  



1.   In  "Screen Mirror Mode" (without SAMSUNG DeX) ,  when holding  SAMSUNG Galaxy Note  9  smartphone in horizontal position ,  I can view the  mirror image of the  SAMSUNG Galaxy Note  9  on the  15.6 inches  External Monitor ,    in  PORTRAIT  MODE , which look something like this or this or this , but sadly , the image in  PORTRAIT  MODE  does not occupy the full screen on the  15.6 inches  External Monitor . But after browsing the Internet using the Google Chrome Browser The image in  "Screen Mirror Mode" (without SAMSUNG DeX)  is "blow up" and it does not look nice because the resolution cannot be adjusted to "1360x768" like what we can do on a  15.6 inches Windows Tablet or on a  15.6 inches  Windows Laptop . Furthermore , the performance in "screen mirror mode" is much faster or snappier when compared in " DeX Mode"  and that makes me wanting to use the   DIY  15.6 inches Smartphone  in   "Screen Mirror Mode" (without SAMSUNG DeX)  more than ever . 

      In  "Screen Mirror Mode" (without SAMSUNG DeX) ,  when holding  SAMSUNG Galaxy Note  9  smartphone in vertical position ,  I can view the  mirror image of the  SAMSUNG Galaxy Note  9  on the  15.6 inches  External Monitor ,   in  PORTRAIT  MODE , which look something like this or this or this  BUT   the image in  "Screen Mirror Mode" (without SAMSUNG DeX)  does not occupy full screen on the  15.6 inches   External Monitor .   
          




The picture above is for illustrative purposes only .   Viewing the [ DIY  15.6 inches  Android  Smartphone ] in  LANDSCAPE MODE  






The picture above is for illustrative purposes only .   viewing the  [ DIY  15.6 inches Android Smartphone ]  display in  LANDSCAPE MODE    A wireless keyboard and a wireless mouse is connected wirelessly to the  [ DIY  15.6 inches Android  Smartphone ] and it automatically become a  15.6 inches Android Laptop/PC .  








The picture above is for illustrative purposes only .    Viewing the   [ DIY 15.6 inches  Android Smartphone ]  display in  PORTRAIT MODE   as shown  above .  It is not recommended to view the display of the [ DIY  15.6 inches Android  Smartphone ]   in      PORTRAIT MODE ( even though we physically position the  15.6 inches Smartphone in  PORTRAIT  MODE )     because the display in the [ DIY  15.6 inches Android  Smartphone ]  will not auto-rotate to PORTRAIT MODE   like what a normal or a traditional Smartphone will do .

_________________________________________  
A real or a true Smartphone with a screen size of 15.6 inches coming from a factory like this will have no problem with auto-rotation . 
__________________________________________

Furthermore , the mirror image of the SAMSUNG Galaxy Note 9 in PORTRAIT MODE  , when displayed on the  15.6 inches  " Touchscreen "  External Montor ,  the display  will not occupy  full screen or the whole screen of the  15.6 inches display .  

2.  With  SAMSUNG  DeX ,  


Hardware requirements required to implement SAMSUNG DeX  on a  15.6 inches  Smartphone :

   1.   1 unit of  SAMSUNG Galaxy Note 9  computer hardware

   2.   1 unit of   15.6 inches  " Touchscreen " External Monitor

   3.   1 unit of power cable or power cord to power the   15.6 inches   " Touchscreen " 
         External Monitor .

   4.   1 unit of  USB 3.1 Type-C female  to  USB 3.1 Type-C  female   Cable .  This cable                is use to connect  the  SAMSUNG Galaxy Not 9  to the  15.6 inches                                        " Touchscreen "  External Monitor .  One end of the  USB 3.1 Type-C  female
        Cable is connected to the  SAMSUNG Galaxy Note 9  computer hardware and
        the other end of the  USB 3.1  Type-C  female  Cable is connected to the
        15.6 inches  " Touchscreen "  External  Monitor .

   5.   1 unit of  microUSB 2.0  OTG Cable .

                          


Software requirements  :

   1.   SAMSUNG DeX application software .  SAMSUNG DeX application software is
        preloaded  inside the   SAMSUNG Galaxy Note  9  computer hardware .

   2.   Android Pie (Android Operating System Version 9)   [ 1 2 3 ] .



P.S.  After making that  DIY 15.6 inches Android Smartphone (that also
              look like a  15.6 inches Android Tablet) , and using it for
              quite a while ,  I still believe using a ready-made  15.6 inches
              Android Smartphone or using a  ready-made  15.6 inches 
              Tablet from a high-tech   Smartphone/Tablet    factory  is
              much much better than a  DIY machine . 
              There are a few things that  I  am not quite happy with this
              DIY  machine , with this  15.6 inches Android Smartphone  machine and I listed
              them below :

            1.   everywhere I go with this machine , I have to carry a
                  backpack with the battery and the inverter inside the
                  backpack and this add some weight .  I wish I can carry
                  my  15.6 inches  Smartphone like  this .
 
            2.   In   " mirror mode " , that is , when the SAMSUNG
          Galaxy Note 9   mirror it's image to the  15.6 inches
                  External  Monitor ,  there is no  "System Utilites" software or
                  "Settings"   software  or   "Control Settings"   software whereby we can adjust
                   the  screen resolution to   " 1360x768 " .   I believe ,  there are many users out
                   there or many consumers out there  who  love to operate their
                   15.6 inches  Smartphone  with   " 1360x768 "   resolution  
                   in   " mirror mode "   because the   15.6 inches  Smartphone   
              seems to operate faster and snappier in  " mirror mode "  
                   compared to   " DEX Mode " .
 
       3. In   " DEX Mode "  ,  that is , when the SAMSUNG
                  Galaxy Note 9  display a  PC-like GUI on the
                  15.6 inches  External Monitor ,  it still show the same problem  just
                  like in  " mirror mode " .   There is no  System Utilites or
                  Settings or Control Settings whereby we can adjust the
                  screen resolution to   " 1360x768 "  in   " DEX Mode " .

       4.  Regardless whether in  " mirror mode "  or   " DEX Mode "  , I cannot open
                     multiple  YouTube session with my 15.6 inches  Android Smartphone  like
                     what I can in a  15.6 inches Windows machine regardless
                     whether it is a  15.6 inches  Windows Tablet or a 15.6 inches  Windows Laptop
                     Due to this , in my opinion , having a  15.6 inches Windows Tablet or a  15.6
                     inches  
                     Windows Laptop is much much better than  having a  15.6 inches
                      Android machine , regardless whether it is a  15.6 inches  Android 
                      Smartphone  or  a  15.6 inches Android  Tablet or a  15.6 inches Android
                      Laptop .
                
         5.  Finally , Android Operating System , regardless whether
                      it is used inside a Smartphone or  inside  a  5G  Smartphone or  inside a
                      Tablet or  inside a  5G  Tablet or  inside a  Laptop  or   inside
                 a  5G  Laptop  or  inside a  SmartTV or  wherever they
                 may be , I have this  wish list for the Android Operating System .
 
                      Android OS wish list ( 1 )  I hope the Android OS developers ,         
                         Android OS maintainers are moving forward quickly in making the
                    Android Operating System an all-inclusive  ecosystem that is richly
                    functional for   users/consumers    at all ends of the computing
                    spectrum ,  so that in the not too distant future , connecting a  Android
                    OS   PC/Desktop   or  connecting a   15.6 inches  Android OS Laptop
                    or connecting a  15.6 inches Android OS Tablet  or connecting an
                    Android OS Smartphone or connecting an  [ Android  OS
                    Laptop/Tablet/Smartphone(ALL-in-ONE) ] machine , like for example ,
                        to  a  USB  printer ( USB Home Printer  and  USB  Departmental
                    Printer ) ,  to  a  USB TV  Tuner ,  to  a  USB  scanner ,  to  a  Digital
                    External  USB DVD-RW  drive ,  to a External  Blu-ray drive , etc., etc.,
                    IS NOT A  TOO  DIFFICULT  TASK ,  just like a  Windows machine
                    running Windows Operating System .  I believe ,  as of today ,  March
                    2022 ,  in my opinion ,  only  Windows Operating System , or to be
                    more precise ,  only  Windows 10 Operating System and  Windows  11
                    Operating  System ,  have  the   capacity/capability to connect to a
                    vast amount of hardware devices .  Having said that , I wish the
                    Android Operating System   could do the same ,  too .  As of today ,
                   June 2022 ,  in my opinion , the  Android Operating System  that is
                   sitting on a   PC  or  on a  Laptop  or on a  Tablet  have some minor
                   hardware/software   issues  when  compared  to running  Windows
                   Operating System  on  a  PC  or on a  Laptop or on  a  Tablet .  It looks
                   like  Android Operating System  works best on a  Smartphone  ,  but not
                   on a  PC/Desktop or on a  Laptop or on a Tablet , which have a big
                   screen , which have a big display , like  15.6 inches or bigger .  Even
                   though   Android OS   work well on a   a  Tablet/Laptop ,  work well on
                     the latest  Tablets/Laptops   available today from a reputable   brand ,
                   yet these  Android-powered   Tablets  and  Android-powered  Laptops
                   still cannot outperform  an  Android OS that sits on a  Smartphone
              in terms of usability and ease of use .     I believe ,  these Android OS
                   Tablets/Laptops ,  have minor    hardware/software   issues
                   because  some  Android smartphone
                   apps   cannot display  FULL-SCREEN properly  when this same
                   Android smartphone app is displayed on  an Android OS  Tablet
                   or an  Android OS Laptop or an   [ Android OS
                   Laptop/Tablet/Smartphone(All-in-ONE) ]  machine  especially when
                   these  machines    have a big    screen/display ,  like  15.6 inches
                   or
                   bigger .  A good example is the   [ 15.6 inches  Touchscreen  " 360
                   built-in DVD-RW Player ] .     Another minor issue regarding Android OS
                   is that , when switching  from portrait-mode  to  landscape-mode  and
                   vice versa , they are not as responsive or swift as compared to
                   Windows Operating System .  It is split second with an INTEL-based
                   Tablet running Windows OS  or  with  an  INTEL-based   Laptop running
                   Windows OS   or  with an   INTEL-based   [ Laptop/Tablet/Smartphone(ALL-
                    in-ONE) ]  running  Windows OS , like for example , the    [ 15.6 inches 
                      Cellular Laptop with  built-in DVD-RW Player ] .
