Play store shows my app as Unsupported for Nexus 7 and others

I'm trying to publish an app to Play Store, but when I upload the app, the Nexus 7 and other devices are shown as not compatible. The app should be restricted to tablets, as its interface is not not for phones. I didn't set requirements for hardware not present in Nexus 7 and I support all displays from 600dp up.
I found similar questions, but all related to camera or phone permissions... any ideas?
This is my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="it.mypackage.stuff"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="12"
android:targetSdkVersion="18" />
<supports-screens android:smallScreens="false"
android:normalScreens="false"
android:largeScreens="true"
android:xlargeScreens="true"
android:anyDensity="true"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-feature android:name="android.hardware.telephony" android:required="false"></uses-feature>
<application> Stuff.... </application>
</manifest>

I found the problem and solved it. I felt very stupid when I realized the problem was I weren't incrementing the "versionCode" field in the AndroidManifest.xml.
The Android Developer Console shows a strange behaviour: if you upload an apk to an unpublished application without incrementing the versionCode, the apk isn't replaced, and no error is shown. So the apk remains the first one uploaded, and all the changes made in the new apk are lost.

android market says no device compatible?

I have developed my own app in android version 8(2.2) and published it in android market. When i tried to install it in my Samsung Galaxy pop (2.2.1) device from market. No compatible device is found. this message appears though i have specified
<supports-screens android:largeScreens="true"
android:smallScreens="true"
android:normalScreens="true"
android:anyDensity="true"
/>
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE"/>
in my manifest file.
can anyone suggest me why android market filtering my app for Samsung Galaxy pop?. Please help me out. Thank you in advance

Finally i got the solution, It was Auto focus feature due to which Google play was filtering my app on Samsung galaxy mini (which doesn't support camera auto focus feature) from Google play.
I have included permission
<uses-permission android:name="android.permission.CAMERA"/>
which by default include auto focus feature true.
so i added following in my manifest file. and it worked for for me
<uses-feature android:name="android.hardware.camera.autofocus" android:required="false"/>
Note : Google play doesn't show Your app on device instantly after uploading. it takes some time so don't panic as i did . if problem still persists clear the cache of Google play.

App won't install on Tablet in market

I'm having trouble getting my app to install on a tablet through the market. Note I'm not using Honeycomb as the app is primarily for a phone. Previousdly I was using level 7 but now changed it to level 10 (2.3.3) to support xlargeScreens. The app installs on my tablet via adb and works great but its not possible to install through the market.
I've read several posts on SO and thought my manifest is correct after adding the supports-screen property.
Here are the most important parts of my manifest:
<uses-sdk android:minSdkVersion="7" />
<supports-screens
android:anyDensity="true"
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:xlargeScreens="true" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Any idea where I'm going wrong?
Thanks in advance.

it's probably your android.permission.MODIFY_PHONE_STATE.
check this official issue that is specific to 2.3+
http://code.google.com/p/android/issues/detail?id=15031
The MODIFY_PHONE_STATE permission was marked as "for system use only" in Android 2.3.
While this was never intended for developers and publicly endorsed by Google, there are hundreds of apps in the marketplace using it. Unfortunately, a seemingly innocent checking by the Android folks has now crippled many popular apps for Android 2.3+.
This is an ENHANCEMENT request that you:
1. Restore the MODIFY_PHONE_STATE permission for Android 2.3.x
2. Create a proper Telephony API for Android 2.3+ (at which time you can remove the MODIFY_PHONE_STATE permission)

If the problem is related to MODIFY_PHONE_STATE
Maybe you can try:
<uses-feature android:name="android.hardware.telephony" android:required="false" />
Never try this, but you can check.
By the way, here you have the information regarding Market-Filtering

App doesn't show up on the Android Market

We've upgraded yesterday our App (easy.go) on the Android Market and after that we have got several messages from HTC Tattoo and Sony Ericsson XPeria mini users, that they can't see application on Android Market.
We are not you using Copy Protection when uploading to the market, so I guess, it couldn't be a problem.
The first assumption is that the problem was beacause of small screens. I took a look in manifest.xml. There is written:
<supports-screens
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true"/>
And here are all permissions:
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-sdk android:minSdkVersion="3"/>
Any suggestions?!
There are some big images with resolution 320x480 and no alternatives for them in resolution 240x320. Could it be the problem?!
Is there some preview before upgrading an app to know for which devices it will be invisible on the market?

I guess, I know now the answer:
http://developer.android.com/guide/appendix/market-filters.html#manifest-filters
If I understood it right
Example 1 The manifest declares <uses-sdk android:minSdkVersion="3">
and does not does not include a
<supports-screens> element. Result:
Android Market will not show the app
to a user of a small-screen device,
but will show it to users of normal
and large-screen devices, users,
unless other filters apply.
Example 2 The manifest declares
<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"> and does
not include a <supports-screens>
element. Result: Android Market will
show the app to users on all devices,
unless other filters apply.
then <uses-sdk android:minSdkVersion="3"/> should be replaced with <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"/>

Have a look at market filters rules if it's not already done, maybe it could help you:

my app do not show in android market but only in some cases

I Have 2 htc tattoo, and I have the next problem, I've made an app and when I upload the app to the market the app is showing on one tattoo but not on the other. Any Ideas?
I have activated all available markets, and deactivated the protections.
My manifest has the next configuration:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.LOCATION" />
<uses-permission android:name="android.permission.CAMERA" />
<supports-screens android:largeScreens="true"
android:normalScreens="true" android:smallScreens="true"
android:anyDensity="true" />
<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="7"/>

Just to be sure, as unlikely at it is-you're not running Froyo (2.2) on your htc tattoo? Its API level is 8 as I'm sure you're aware.
Check if you have a folder named /lib in your apk, its a weird thing the Market application checks for, and if it exists your application won't display.

Ok the problem with tattoo is that it do not support autofocus and it is necesary add in the manifest:
