Low memory, apps crashing - change zram settings or add swapfile? [4.x]

Have the same Problem and it is anoying as hell! It happens not only once a day, that all apps or at least all android apps are closed while phone is laying arround. No Android, no Nextcloud talk messages are ariving anymore. You only get notice of it if you get a call, asking for response :confused:

4.2.0.21 does not make anything better!

Has someone reported this via zendesk? Maybe none of the responsible at Jolla is reading here…
