[Motorola Atrix 2] acehunterz:
I just bought the Atrix 2 few days back and I notice that after the phone has been started for a while, and I restart my phone, the APK cannot be installed anymore.

Model: MB865

Android Version: 2.3.6

Kernal Version: 2.6.35.7-g313792c

Build Number: 5.5.1-EDEM-27

Details below:

1st Attempt:

- Bought the phone and transferred my SD card with my previous phone apps backup in APK.

- Did the initial phone setup by tagging the phone to my google account, went into Google Market to install a battery status apps, surf some web, etc.

- Restart the phone and when the phone turns back on, tried select the APK file, enable the "Allow install of non-Market applications" and continue with the apk installation. It came out the permission page with [INSTALL] & [CANCEL] button at the bottom. Tried touching the [INSTALL] but no response. It's like a dummy button. Then [CANCEL] will exit the permission page.

- Tried other apps in APK, same issue.

- Called Motorola support line and she asked me to Factory Data Reset my phone from the Privacy in the Setting page.

2nd Attempt:

- Initial setup my phone as per usual by tagging the phone to my google account. Once the phone started, immediately, I use the file manager to browse my APK backup folder and install some apps with no issue. The [INSTALL] button can be clicked and apps installed properly.

- Use the phone for a while, restart the phone and turn back on... tried install other APK again... same issue happened, the [INSTALL] button became a dummy button again.

- Factory Data Reset my phone from the Privacy in the Setting page again to try again.

3rd Attempt:

- Suspect that it may be automatically downloading some apps from the google store, so this time round, I just turn on the phone without tagging to any of my account, not even my google account so that the phone should not automatically download apps from the market that may clashed with the system.

- Use the phone to do basic web surfing for a while, and then restart the phone.

- Phone restarted and try to install APK files, same issue happened again.

With the above tries, I suspected the issue (APK cannot be installed because [INSTALL] button cannot be clicked) is not due to any apps conflicting the system, but maybe some hidden updates download from google unknowingly that is incompatible to the Android system.

Further findings shows that my bro has a Atrix 1 and I asked him to restart his phone to try install some APKs, same issue with [INSTALL] button.

My 2 other friends has a LG Optimus One and LG Optimus Black, both running Android as well. I asked both to restart their phone and try to install some APKs, and everything works fine.

I seriously think that there are some conflict with the some google "hidden" update, maybe Play Google?, that disabled the [INSTALL] button as initially when phone factory resetted is ok. If this is the case, no point to go down Motorola repair centre as they cannot do anything as well until new updates from Motorola available.

Will anyone with Atrix 1 or Atrix 2 phones kindly check if you have such issue? Restart your phone 1st if the initial attempt is working as the update may activate only after the phone is restarted, such as the icon changing Google Market to Play Google, that disable the [INSTALL] button when installing APKs.

Let me know if you have a non-rooted solution, ok? Do not intend to root my phone yet. Thank you.
