App no longer compatible after Unity 4 upgrade

My app is no longer compatible on some phones after I updated to Unity3d 4. I’ve only received a few complaints, but its a bummer that those users can’t update to the latest version.

I checked the Manifest for my last version and my new version with the update and the only difference I found was:
application-con-320 was added
densities now has 320 in it

uses-feature:'android.hardware.touchscreen'
uses-implied-feature:'android.hardware.touchscreen','assumed you require a touch
 screen unless explicitly made optional'

WAS CHANGED TO:

uses-feature:'android.hardware.touchscreen'

sdkVersion changed from 10 to 7
native-code is now armeabi-v7a instead of armeabi

I think it is one of the last 2 that did it, but not sure if this is even fixable??? Any ideas?

Unity 4 doesn’t support ARMv6 processors… So it doesn’t work on more low ended androids like Galaxy Y and Galaxy Gio…

Yeah my apps always been set to arm7 in unity3d. One of the phones that did work and now doesn’t is the lg optimus v which is an arm7 phone.

I read at the link below that armeabi-v7a code is not compatible with some older phones. I wonder if there is a way to tell unity to use the armeabi instead so I can make a separate apk for those users

LG Optimus V is NOT ARMv7, it uses a MSM7627 QC chip which is has an ARM11 core that implements ARMv6.

As Joel already stated, Unity 4 does not include support for ARMv6 (armeabi). The only way to target phones with the ARMv6 chipset is to use a Unity version prior to 4.
