Ok, it was much easier than I believed. I just had to query the contacts.db (I used DB Browser for SQLite) as select vcard from folder_id;. select all results, copy and paste them into a text file and save this file as contacts.vcf. open this file in Android, confirming that contacts need to be imported.

I must admit I feel the same about MC Hammerhead... I have downgraded to a Nexus 4 - much better battery life. The other issue with the 5 that I have had is the on off button failing and that has put the device in a boot loop. The switches are crazy-tiny - and look difficult to replace. Good luck with your battery experiments and please post if you get a good solution.

@dad_and_alive I'm glad to hear that your issue is fixed

@pulsar33 @dad_and_alive now ti has only the a) feature, but feel free to report an issue on its github page to add these features

I think I spotted an interesting one, not showing any side borders (only angular ones): https://www.amazon.com/iGadgitz-Premium-Leather-Multi-Angle-Protector/dp/B00HDFYDEE

note to self: RTFW (i.e. rtf wiki) before posting ... the bug trackers are listed at https://wiki.ubports.com/wiki/UBports-Bug-Trackers/da00bef and my 'bug' was already listed here https://github.com/ubports/notes-app/issues/2

@dad_and_alive Sad... My daily driver MX4 is still OTA15 and performing quite well. I recentlly added UT Openstore to keep some SW up to date as far as possible. I bought a second hand N5 too but for testing purposes. W.
