Although the s8 is second hand from my grand daughter there seems to be a common fault, that the motherboard is shot due to the design of phone allows it to bend and then "no service" happens. Been in contact with "you" but had no joy from you so had motherboard replaced by phone repair local to me, and they've made a brilliant job.

The speed of the phone is really good and the farmers has a nice capture to and thing such as clouds or the sky

It is relatively easy to operate. The apps I use work. I am happy to explore features - but don't want to waste time on the phone - so it just does what I need it to do now. I don't know what I will need tomorrow.
