How I eliminated nearly all of my Ativ S reboot problem.

[Coolknight1968]

As I said before, I was having reboots on my Ativ S, mainly when the data connectivity was being lost.
It is a bug that was once present on the HTC 8X.
I even spend some time creating conditions where my Ativ S will reboot.

Now today, I have some good news! My phone has been up for nearly 5 days now, NO reboots!

So what did I change?
I went through all my apps and deleted all those I hardly ever need. Like ie. Verge reader, Local.ch etc.
Then the remaining apps, I allowed all of them to run in the background.

So, if you have reboots, try allowing all apps to run in the background. If you blocked some and uninstall all apps you don't really need cause you can access the website over the IE browser.

Also, I installed an app called "LastBootUpTime" which allows me to keep an eye on reboots.
Last I switch networks manually before I go to the area where I need to roam on another network.
(Network name issue as it is the same network but under another name, so I don't pay for roaming.)

Try this, I hope it helps.

My Ativ S runs Firmware 2424.12.12.3 on Swisscom in Switzerland.

I'm waiting my Ativ S, but now I have a 620 and 2 or 3 times a day it reboots, I'll try what you say, but I like to have so many apps installed...=(

I also like apps. Try to unblock all at first.

I forgot to say here that I cleaned up bad music files and wrongly displaying files (WP8 audio player) on my cat4 32Gb microSD card. (Sandisk).

I have an Ativ S and I'm so pissed about this! This is ridiculous! Even if your "trick" work, what's the point making your battery fly way in half day?
