How To Get Real Serial Number Of Lenovo Tab In Android

I am trying to get the serial number of my Lenovo Idea Tab running Android. I tried all the options available in Google search, which are: Class c = Class.forName('android

Solution 1:

I recently had to also get the SN for a lenovo tablet. You can use the following methods

publicstaticStringgetIMEI(Context context) {
    TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    return telephonyManager != null ? (telephonyManager.getDeviceId() != null ? telephonyManager.getDeviceId() : "N/A") : "N/A";
}

publicstaticStringgetSN() {
    String deviceSN = "N/A";
    try {
        Class<?> propClass = Class.forName("android.os.SystemProperties");
        Method getProp = propClass.getMethod("get", String.class, String.class);
        deviceSN = (String) getProp.invoke(propClass, "gsm.sn1", "N/A");
    } catch (Exception ignored) {
    }
    return deviceSN;
}

publicstaticStringgetPN() {
    String devicePN = "N/A";
    try {
        Class<?> propClass = Class.forName("android.os.SystemProperties");
        Method getProp = propClass.getMethod("get", String.class, String.class);
        devicePN = (String) getProp.invoke(propClass, "ro.lenovosn2", "N/A");
    } catch (Exception ignored) {
    }
    return devicePN;
}

Lenovo has custom property names, you can use the following adb command to see all available props:

adb shell getprop

I used this code to get the serial number from the Lenovo tab 7 Essential (2017 model running Android 7.0). I was also using it to get Samsung serial numbers (Galaxy Camera 1/2 running Android 4 and a Tab A running 6, then updated to 7.1.1).

privatestatic String UNKNOWN = "unknown";
static String GetDeviceSerialNumber() {
    String serial;
    if (Build.MANUFACTURER.toLowerCase().contains("lenovo")) {
        serial = GetLenovoManufacturerSerialNumber();
    } else {
        serial = GetSamsungManufacturerSerialNumber();
    }
    if (serial == null || serial.equals(UNKNOWN)) {
        serial = Build.SERIAL; // this is NOT usually the serial displayed on the device, but it returns something
    }
    return serial;
}

    String serial = GetSystemPropertyString("ril.serialnumber"); // older Samsung devices - works on Galaxy Camera 1if (serial == null || serial.equals(UNKNOWN)) {
        serial = GetSystemPropertyString("sys.serialnumber"); // newer Samsung devices
    }
    return serial;
}

    return GetSystemPropertyString("ro.lenovosn2");
}
privatestatic String GetSystemPropertyString(String prop) {
    try {
        Class<?> c = Class.forName("android.os.SystemProperties");
        Method get = c.getMethod("get", String.class, String.class);
        return (String)get.invoke(c, prop, UNKNOWN);
    } catch (Exception ignored) {
        ignored.printStackTrace();
        returnnull;
    }
}

Hopefully that's helpful to someone.

HI you can get everything about your device hardware by using the following code.

Build.BRAND  //Brand Name

Build.DEVICE   //Device Name

Build.MODEL   //Model No

Build.SERIAL  //Serial No

import this namespace :: import android.os.Build;

Let me know if my answer is right or not.
