Hi,

First what I know: I have installed two OTA updates on my Austria sourced Note and aside from the slightly modified standard keyboard I cannot say that I have noticed much.

Next what I am speculating: I would say that, unless you have a hardware problem with your antenna, you probably have more of a signal problem that a firmware one. Do you haven't 4 bars of signal when this is happening or are you barely connected? The H and H+ data rates are negotiated on top of the 3G signal so you need to have a good connection to get them. Do you have the problem everywhere or just in one location? Do you also lock your Internet connection when using WiFi?

Not much help so far but I hope that this gives you some pointers.

Regards,
Eric Ritchie.

 

Do u have some app like June defender installed if so try disabling it......

Best of luck

 

My spec is absolutely identical to yours (except you dropped one of the 0's off GT-N7000). I bought mine from Expansys in the UK. I'm not sure there is a UK spec model as such as they all seem to be known as the international model but at any rate yours is absolutely identical to mine.

As for your 3G issue, I live in an absolute dead zone for 3G so I deliberately keep mine off otherwise it kills the battery constantly hunting for a signal. I use the JuiceDefender Ultimate widget to force 3G off and on. When I'm out and I need it on it's just like yours, constantly changing to H or H+, sometimes dropping to E (for Edge, basically GPRS speeds). It's down to the strength of the signal. The phone is trying to find the best signal it can to give the best speed it can. If you sometimes have to turn it off then on again it seems that something is either disabling it or interfering with it. You need an app that monitors not only 3G usage but can also tell you what apps are using or controlling the 3G connection. I don't actually know of any, purely because I haven't needed an app like that, but someone on the forums might know of one.

 

This is the latest official ROM and it's really buggy. At least I couldn't stand it and had a lot of problems with it. I then tried a lot of custom ones and finally I chose ICS Stunner, an Android 4.0.3. It works awesome, it's based on AOKP with all the Euphoria controls and I'm very happy. A downside for some might be that you're stuck with Apex launcher and miss the Samsung Galaxy Note apps for the S-Pen.

If you want to give it a try, here's a guide: How to update Samsung Galaxy Note N7000 to ICS Stunner 4.0.3
