My tablet is unsupported for a react-native android app

I am using a react-native android app. And my device is not supported because it does not have the required feature: android.hardware.telephony.
Yes, I do not have telephony in my tablet. But, I am not adding this required feature in my manifest. So, where exactly is react-native adding this required feature in the build? And how can I turn it off.
My manifest file is below.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.kalhatti.main"
android:versionCode="5"
android:versionName="1.5">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-sdk
android:minSdkVersion="16"
android:targetSdkVersion="22" />
<application
android:name=".MainApplication"
android:allowBackup="true"
android:label="#string/app_name"
android:icon="#mipmap/ic_launcher"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:windowSoftInputMode="adjustPan">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
</application>
</manifest>
Thanks.

To allow the app to be installed in tablets, add the following to AndroidManifest:
<uses-feature android:name="android.hardware.telephony" android:required="false" />

Android App not compatible from play store but works in debug mode

The mobile I am going to talk about is Micromax A63, Android Version 4.2.2
When I was developing my app, I used it as a debug device and it worked fine. All the development is done on the system.
After development, I uploaded the apk to play store and registered as a beta tester. When I see the app in the play store it says "Your device is not compatible with this version"
I have checked the compatible list, interestingly this device is neither in Supported Devices List nor in Unsupported list.
I have the following in my gradle build
minSdkVersion 13
targetSdkVersion 22
The permissions i use in the app are
<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.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Help me understand what could be the issue.
Complete manifest file is as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.ghr.ubietyapp" >
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

How To Avoid Google Play Services Update Required Warning

I'm using Google Maps in my Android app and I'm seeing the following message on some older devices:
I understand the nature of this message and that updating will resolve this issue.
However I would like to avoid users seeing this all together, and just want the map to load on all devices.
Here's what my dependencies look like:
Please note that I added individual parts of Google Play services that I needed rather than the full library as I started receiving an error from Android Studio about too many lines of code - this was the work around as I just have to many libraries as it seems.

Ideally I would like to know how to have the map just load and not force the user to update as my minSDK=10 and the app supports Android 2.3 devices and up.
Even if that means targeting a lower version of Google Play services to support SDK 10+ I'm ok with that solution.
Thanks!

However I would like to avoid users seeing this all together, and just want the map to load on all devices.
Then don't use Maps V2. Instead, use some other mapping solution (e.g., Open Street Map).
Otherwise, there is no "magic" dependency that will avoid this dialog on all devices. While you are welcome to use some older version of that play-services-maps dependency, there is no guarantee that ~1.5 billion devices will all support that particular version of the Play Services engine without any updates.

App dont show in market for tablets

I've done an app and I've tried it on my tablet via USB.
But when I uploaded it to market it didnt show for my pad... :S
I guess the problem is in my manifest...
Here is my manifest:

What do I need to add?
BR

android:name="android.permission.WRITE_EXTERNAL_STORAGE"
That's your problem there. Some/most tablets don't have external storage. Either use internal storage (in which case you don't need a permission), or try adding android:required="false" to your WRITE_EXTERAL_STORAGE permission. Either way though, you are going to have to go into your code where you are writing to external storage and change it to internal, or handle the case where a tablet doesn't have external storage.

Are apps fully compartmentalized?

I am running into an issue that is confusing me. It seems as if android apps are NOT fully compartmentalized is this the case.
I have a Samsung SIII phone and I am building apps that are used as templates. Basically it is the same app but with different content the content is retrieved from our database at startup.
So my process is to create a single app get it working, then copy it to another package through refactoring and I change the data retrieval calls and I have two apps the internal functioning and coding is basically identical.
What I am seeing is this I start one app and it seems to be working just fine and I can open and close it several times with no issue, then out of the blue I get a pop up that says a certain app has stopped functioning. The issue is I never opened that app I could have opened one of the duplicates but I even forgot I had the app that crashed on the phone let alone starting it.
I routinely shut down all running apps just to make sure things run smoothly and I never see that this mystery app is running anywhere.
The shut down message just simply appears but it is always after running apps that ran the same code but not all the time.
This may be the reason I have seen some other issues but can't tell
the basics of the other issue is two sets of code that are pretty much identical per my process where one works and the other doesn't
I am very confused
Can anyone help clear the smoke?
this may help it is a list of my permissions
uses-permission android:name="com.android.vending.BILLING"
uses-permission android:name="android.permission.INTERNET"
uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
uses-permission android:name="android.permission.READ_PHONE_STATE"
uses-permission android:name="android.permission.ACCESS_WIFI_STATE"
uses-permission android:name="android.permission.BLUETOOTH"
The content for all of my template apps will be VERY similar except for the package name versions etc.

I do see the min SDK version has changed I don't remember doing this right off hand but I must have for some reason
