I'm using RX100, my sister using Canon G7x

I think you can consider RX100 III, G7X or Panasonic LX10 or LX100.

RX100, G7x Mark I or Mark II & LX10 have same sensor size (1")
LX100 has micro4/3 sensor size, which is almost double of 1", with very bright lens (F1.7-2.8, focal length 24-75mm) but 12MP resolution output, and this model quite old.

Had 3 incidents when my RX100 failed on me, luckily just temporarily
- Korea Mt. Sorak, camera too cold and battery stop functioning and the lens sticking out. Change a fresh battery and it came back to life. I didn't count how many photos taken but definitely battery life shorter. Later I just keep it under my armpit when not taking photo, and it's fine.
- There is a function when I long press the play button to review photos without switching on (also lens not moving). After reviewing for 30+ minutes, the camera won't start anymore. Remove & re-insert battery will solve the problem
- Change button too quickly and it hang. Remove & re-insert battery will solve the problem
