Interesting development. I just downloaded Kongregate Arcade. Under menu>storage options it allows you to choose internal or external and it also gives you the amount of storage left.
While under SD and Phone Storage it shows I have 580MBs available Kongregate Arcade only shows 31MBs!
Obviously this is looking at that data/data folder and proves that there is a limit on app storage.
We should flood HTC's inbox about this!
If you would like to see how much you actually have left and you are not rooted download this app and you will see.
Edit: This is what I just submitted to HTC. I doubt they will do anything with it though. I would love them to acknowledge there is an issue and that they are working on a fix but I am sure they will just give me the same boxed answer as before.
"I have an HTC Droid Incredible. I have emailed before about the app storage issue but have just gotten the standard reply that it must either be a 3rd party app or I need to do a hard reset. No one seems to address the issue at hand that HTC has limited the amount of storage available for app storage.
Although I have been told several times that all 748MBs of storage is available for apps that is not true.
I recently downloaded an app (from the Android Market) called Kongregate Arcade. This app has a feature to choose where (internal or external) to store the games you may download through their portal. In addition it shows the space remaining. My phone tells me I have 580MBs remaining but this new app says I only have 31MBs!
I have cleared all my cache as you have instructed me in the past to no avail.
I have gone to many forums and have found that the data/data folder is limited. No one knows for sure what that limit is but I know for a fact I do not have 748MBs of apps on my phone.
Please! Please! I spent my hard earned money on the phone only to find out that HTC lied to me about the storage.
I do not want to go and buy an iPhone that allows me to store 16 or 32GBs worth of apps if I wanted to.
Fix this issue ASAP or you may lose many customers!"
