I use my Samsung Galaxy Note 10.1 for university. Last semester it downloaded all my PDFs and i imported them into S Note for my lectures and tutorials. I am not sure why, but every PDF i try to download wont work. They are 'Ongoing' for a long time and then they all just fail for some reason. Apps download fine, and i've downloaded the latest updates. Please help, it is useless for me if i cant use it for uni.

SOURCE: I am using samsung galaxy tab. The OS update

Galaxy Tab is not running on OS 3.0 (Honeycomb), that is running on the Xoom only. Samsung would have to release an update for your Tab themselves. Google makes it available and only Samsung can make that decision.

SOURCE: Why i can't download yahoo

Here are the facts.
1. Samsung Galaxy 10.1 is running Android 3.1.
2. Yahoo messenger is ported till Android 2.2.

Solution:
1. You may have to wait for sometime time till Yahoo compiles IM in Android 3.1.
2. Use android 3.1 provided IM client to connect to Yahoo Messenger.

Hi astone5638,

The first thing to try to correct this issue is to remove the battery and SIM (if you have on, varies by carrier) from the phone and wait 20 seconds, then, with the battery still out, plug it into your wall charger, then place the battery and SIM back in and turn the phone back on.

Hope it helps.

Thank you for using FixYa.
