unknown error, insufficient memory

Dear community,


Whenever I run my app offline, i get "an unknown error occured" and also when i want to SaveData from a collection I get "there was insufficient memory to save your data; Please reduce the amount of data you are attempting to save",


when I actually am saving very little data.

I check that my phone has enough memory, I have tried to run it on other phones but I still encounter the same problem error messages.


Could anyone help me please?

Hi @blue_lotus,

Could you please share a bit more about your SaveData formula within your app?

What size is the RAM within your Mobile device?

Based on the error message that you mentioned, I think you have faced a insufficient memory issue with your Mobile device.

Please take a try to clear cache of your PowerApps Mobile App via clicking "Clear Cache" option within your PowerApps Mobile App.

In addition, please take a try to filter your source data, and just cache necessary data into your mobile device using SaveData function, check if the issue is solved.

Also please take a try to run your app within a Mobile device which has larger RAM, e.g. 8 GB, or within a Tablet device (e.g. iPad) then check if the issue still exists.

If the issue still exists, please consider take a try to uninstall the PowerApps Mobile App from your Mobile device, then re-install it, run your app again, check if the issue is solved.


Best regards,

the RAM is 4 GB, of which 1.4 GB is free.

I have cleared the cache of Power Apps.

My code is below. The collect function works. Because I can see the collection in a gallery. 

But the savedata does not. Thank you for your help






Collect(offline_records,{c_date: DataCardValue18.SelectedDate,c_centre: Dropdown1.Selected.Value,c_bag: DataCardValue19.Text,c_sample1: DataCardValue20.Text,c_sample2: DataCardValue21.Text,c_sieved: ListBox1.Selected.Value});
