App version not getting updated

Question

I've an application in the market. A month ago, I updated the application with newer version. I've changed the appVersionCode as well as appVersionName in the manifest file. In my database, I'll fetch the current version which user has got installed. In this database, for few of my users, I can observe that app'version still shows 2.2 when they have actually updated it to 2.3. For the rest, the app's version have got updated successfully. I tested my logic and flow as well. I could not recreate this problem. I'll be grateful to any one's help.

The database updation which I was talking about has the following code:

UserVersion is my local Database. It consists of Device's UID and Version of my app.

When a user installs next version, I get the Version of the application by using the following code:

PackageManager manager = getApplicationContext().getPackageManager();
PackageInfo info;
try {
    info = manager.getPackageInfo(getApplicationContext().getPackageName(), 0);
    String version = info.versionName;

If this version is different from my local database's version, I'll update it.

Mainfest file is shown below:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="sa.appoptix.com"
    android:versionCode="2"
    android:versionName="2.2" >

Below this, uses permission and application tags are used.

you can update APP version from AndroidManifest.xml file , this is a configuration file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="xxx.xxxxxxxxxx.android"
android:versionCode="1"
android:versionName="1.0" >

version code increment by 1 when update new version. version name you can put it as this format 1.0 / 1.0.0 , 1.x.x
