  • According to the Netflix website the EVO 4G is supported only when running Android 2.2.  Sprint and Netflix are working together to resolve this.

Voicemail notification

  • New discussion thread for this topic:
  • Root cause has been identified for the VVM notification issue and a short term solution began rolling out the morning of 6/9.  The rollout is occurring in batches with the first devices upgraded to Android 2.3 receiving the short term solution first.  This fix is network based and does not require customer or device interaction. 
  • Sprint is currently working on an updated version of the Android 2.3 Gingerbread software which will include a permanent solution for the VVM notification.  The short term solution will continue to be deployed until this new Android 2.3 upgrade is available. 
  • You may continue to use Settings/Call/Clear Notifications until the short term solution has been rolled out.

You have to do the following:

Hold down your finger on a blank area on your screen>select widget>goto settings>select HTC Profile.

This will put a shortcut on your screen that allows you to change the volume via touch.




I removed Handcent and then powered the phone off and on now it works fine.


Thank you.



- SplashID no longer syncronizes with desktop

- sound profiles via power button - a big deal for many people, myself included. I hardly ever reboot, but I change my sound profiles several times per day.

- PRL and FW updates error out, but I believe this may be due to bandwidth issues Sprint is having

- 720p video recording is unusable now. I used to record my son's tennis games. I can't do it anymore because it drops frames, and video and audio are way out of sync A BIG DEAL FOR ME!

+ nice feature showing text marker when editing/entering text, and cut/paste magntify - really nice.  however the normal feature for swype selecting alternative words conflicts, requring selecting the swype shortcut key (I actually like this new feature, just wasn't clear at first)

+ phone does appear slightly snappier and responsive


Did the GB update, and now Wireless-N is gone! Only have b/g. What's going on?


Yup, connecting to wi-fi above 54 Mbps (Wireless-G) is a goner. When  the Evo first came out with Eclair and b/g support, the dev's at XDA  found a simple hack to enable 802.11n but then when the Froyo came out,  it worked out of the box. Technically, 802.11n requires two antennas so  true Wireless N connection speeds (150 - 300 Mbps) could not be  achieved.

But,  up until this update, I could connect to my wireless N only network at  65 Mbps. I had to enable mixed b/g/n mode in my access point to even get  a connection but alas, it's only at 54 Mbps.

I want my missing 11 Mbps back.


I did the Ginger Bread update and it works so much better than the 2.2 fuck up!!! i dont know why is everybody having a problem with it. me and some my co workers did the update at the same time and we all like the update!!


You do of course realize that regardless of the connection g,b or n, they really don't download at 100MBPS right? Not even 54 for that matter. The best download speeds you are going to get, regardles s of wireless router, is about 6 mbps. Even with the two bigger companies.Your router is lying to you. Use a free online speedtest even when you are hardwired and you will see what I mean.

The frequencies on the channels are capable of those speeds. But you don't get them. In the little "Internet Connections" on your computer are lying to you.

4G is faster than most DSL's. Networks are throttled. It would be great if it acutally was 100mbps, but that's not gonna happen for years until the true standard protocol is IPV6.


An Update:

I just finished the last update (3.70.651.1) as well as the upgrade of Android 2.3 (4.22.651.2). Everything went flawlessly and my HTC EVO 4G seem working normally. A couple of apps need to be reset (alarms, weather, etc.). Other than that, everything seems fine.

I guess the problems many other users experienced apply to different users, depending on the phone's configuration, apps installed as well as if it is rooted or not (mine is not rooted).

Again, thank you for the patience. I am glad I came to this forum and read all the pros and cons and asked all the questions.


I just finished the update & phone is just fine!  No issues with the voicemail notification.  I do have the same issue with the Netflix app, but I see it's been reported.


Glad to hear!  I'm glad that the negative comments in here did not hold you back from missing out on the gingerbread 2.3 goodness.  It truly is in everyone's interest to upgrade whether they know it or not and like all things there probably is an ton of folks out there that won't upgrade based off of misinformation.
