iPad Mail app freezes when selecting email

Do you have SplitMail installed by chance?

 

Do you have BatteryLogger Plus installed?

I had the same problem but after uninstalling this app, the problem went away. It was also causing other apps to crash. Mail app was the only one that was freezing on me though. It was very buggy.

I have SplitMail on my iPad 3 but it has always ran very smoothly, no problems at all with it.

 

Hmm I don't have either of those but I have heard that both of those can slow down your device considerably. Whether or not they're buggy as well, I don't know. It may be that as you have both of them together, they're not playing nicely together.
Maybe someone else who knows could chime in....

Yes, it would be a good idea to post all of your Cydia apps/tweaks. It would then be easier to weedle through them.

How long has this problem persisted? Which app(s)/tweak(s) was it that you installed not long before the problem started; can you remember at all? If you can think, this will help immensely as you won't have to go through tweaks that were installed in the beginning.

Good luck.

Excellent! I know how frustrating it can be when a Cydia app/tweak messes with your other apps. Took me a good couple of weeks to work out what was messing with my mail app. Got sick of uninstalling and reinstalling stuff.

I would of liked to try Winterboard myself but I heard too many problems with it so I left it well alone.

 

Oh dear, this sounds like the problem I was having. I would uninstall one tweak and think 'BINGO! Problem solved.' An hour or so later, the problem would return. Soooooo annoying!

Did you have Winterboard installed again when you reinstalled SplitMail? Maybe they're conflicting. Could it be a particular WB theme conflicting with SplitMail?
I don't think SplitMail is causing this alone as I have it on my iPad 3 and it's always worked fine. If it is SplitMail causing the problem then it's happening because it's conflicting with another app/tweak.

Is it just your mail app that's freezing or are any other apps playing up?

 

Hmm.... *scratches head*

Do you use iFile to delete the .plist files left over from uninstalled Cydia tweaks? Maybe you need to uninstall Winterboard, Dreamboard and SplitMail completely. Then, do a reboot and see how things run.

If you don't know how to delete a Cydia app/tweak completely using iFile, here's how -

Go to iFile and then click preferences and delete each .plist file for the corresponding app/tweak. Be careful not to delete anything that is com.apple
Everything else corresponds to a Cydia app or tweak.

Also delete the ones you want through Cydia first and then go to iFile and delete the leftover .plist file.
Then do a reboot and see how things are.

I think WB and DB leave themes and whatnot in another folder. I am not sure where these folders are located on iFile but I've come across it on Google before. I would also delete these and everything else related to WB and DB through iFile after deleting through Cydia. This makes sure that all traces are completely gone and are not messing with your device any more.

I'm crossing my fingers for you that you'll get this sorted asap!

 

Simple Fix

In my case, i just changed the font size and the lines previewed per message in the left column.

So after those changes i could use the mail app normally. No freezings anymore.

PS: The problem started when i uninstalled the hackulous (installous) appstore.
