     BACKGROUND OF THE INVENTION 
     Modern day portable electronic devices have charging port on the side edges of the device. While charging if the Android device falls, accidently, the Micro USB Android Connector stein of the charging cable can collide with an object or the ground. This impact will exert excessive force on the charging-cable connector-stem, the charging port mounts, and the connection pins. Such events can cause damage to the device charging port, or the charging cable connector-stein or both. If Android device falls into a confined space where user can&#39;t reach, the normal tendency is to use the charging cable to recover the device. Such event will exert force on the charging-cable connector-stein, the charging port mounts, and the connection pins. Above said excessive force will bend the Android Micro USB Connector-stein and damage the user device port. This damage will result user to replace the charging cable or the Android device or both. 
     To avoid the added financial burden, the low cost Improved Micro USB Charging-Port (IMUCP) was invented. Further the invention uses parts already available in the market. Therefore, Android device accessory manufactures can continue their production without changing the manufacturing process. Completely changing a production line will cause a fortune for manufactures and it will increase the cost of the product. Small modification to production lines of user-device manufactures will not soar the market price of the product. User device manufactures change the device appearance, configuration often to produce new versions. Hence the user-device manufactures production lines are more flexible than the accessory manufactures. There for the feasible solution is to make small changes to the user device at manufactures level to stay compatible with the accessories in the market. For the existing user devisees, introduce an interphase compatible with the accessories available in the market. The invention will allow the existing users to continue with the user devices and the accessories already they have. There by the invention will help the household to save money as well as the accessory manufacture to continue their business without any added capital expenditure. 
     The invention will add protection to the Android devices, such as waterproofing and protection from impact. The Improved Micro USB Charging-Port won&#39;t hinder or alter the original functions and the flexibility of the Android devices currently exist in the market. The invention allows the user to answer the calls usual way with privacy while device is charging. IMUCP is user friendly and preserve the handheld Android device versatility and the originality. With IMUCP there is no requirement to place the Android device on a docking station to charge the battery or transfer data. 
     FIELD OF THE INVENTION 
     Patent primary class to be determined by USPTO. 
     SUMMARY OF THE INVENTION 
     Invention is named as Improved Micro USB Charging-Port, and hereafter will be referred to as IMUCP throughout this document. IMUCP will perform following. The default, charging and data, Micro USB female Android type port is replicated on the back cover, away from the edges, of the Android device. 
     The IMUCP is compatible with the regular Android charging cables available in the market. IMUCP has two versions. The aftermarket version called IMUCPAMV and manufacture version called IMUCPMV. 
     The IMUCPAMV is a modified Android charging cable with a microchip and a modified regular phone case combined to gather to replicate the default charging-data port of user device with an Android type two Micro USB female connectors to provide two separate ports such as one port exclusively for charging and separate port exclusively for data transfer. The modified Android type charging cable consists of Micro USB L shaped Male Connector attached to a flexible four pair electrical wire and a microchip with two Micro USB Female Connectors are attached to the remaining end of the same wire. The micro USB Male L shaped, Android type, Connector is semi-permanently, externally, plug into the user device default charging-data port: the other end of the cable, with microchip and two Micro USB Female Android type Connectors are secured to the back of the protective cover of the device. 
     Two Micro USB Female, Android type, connectors will split default charging port into two ports such as one Micro USB Female, Android type, Connector exclusively for charging and a separate Micro USB Female, Android type, Connector exclusively for data transfer. 
     The IMUCPMV version is a miniaturized version of IMUCPAMV: that can be integrated into the Android device during manufacturing process. The manufacture will use the parts they already have along with few new once. 
     Improved Micro USB Charging Port Manufactures Version replicate the default Micro USB female Android type charging and data ports by using a microchip and Android type two Micro USB female connectors to provide two separate ports such as one port exclusively for charging and separate port exclusively for data transfer on a popup flap and pop up flap is sunk in to the device chassis from the back of the android device. The replicated charging-data ports will be compatible with regular Android type charging cables available in the market.
