Google Play Store " 您的设备与此版本不兼容"

I see lot of questions about this problem but no definative answer. We are app development company and recently launched 2 new apps on google play store. We tested those apps on Sony Ericsson phone OS ( 2.3.4) with below MinSDkVersion mention in Manifeast.xml file. APK is installed succesfully without any issue. We tried on another phone with OS version 2.3 but shows same problem in google store.

Lot of our users are complaining that they don't see our app in play store.

Is something changed?

Here is another intresting thing. When looked at app through Chrome browser. It says device is compatible.

When clicked on install. It starts installing and fails with error "Could not be downloaded due to an error ( 942 )

There is chance that You have made some changes that can not work on 2.3 as you have said that It was working fine before week, It means you have made some changes that now not workling for version 2.3 So that It shows " Your Device isn't compatible with this version" as per official website

is there no such updates from Google

For more official details - Android

It seems like your application requires a feature that one of the devices doesn't support.

You should also check to see if you have the following declared in your AndroidManifest.xml,

You want your application to work for devices running API 9 and above (not APIs 9 through 17). The code above will ensure that your application works with all devices above API 9. Note that you generally don't want to use the android:maxSdkVersion attribute (as you are currently using it).

Try clearing data from download manager (settings-apps-all) and play store, then remove your google account, then go to play store and it will ask you to link your account after that try downloading the app. (That worked for me).
