Finally got my unit, ip7 128gb in black and it has already got a Spigen Glaz screen protector and Neo Hybrid case.

Coming from a ip6+ and SE, this ip7 rocks. Its faster, more fluid, generally more joy to use. With ios10, there are more settings which further enhance the user experience.

So sifus, which app is recommended for memory management, cache cleaning, general housekeeping?

Thanks in advance

if given choice,

I would go for matte black..

This iPhone 7 Plus finger print got one big issue is where it can't have single wet. It won't registered your finger print even when your hand is wet. It needs to be 100% dry. If your hand is always sweaty then you need to always wipe dry before use the finger print else it won't work.

I gonna said the worst ever implement finger print, it is fast and accurate if only your hand is fully dry.

Just try out, seems ok for me. Anyway I seldom use phone when charging. Shall be ok for me.

But the wet thingy, hope Apple able to fixed it in future.

I observed this, not sure same conditions and scenario like you. When "over-charging", leaving it with the bundled apple adaptor and connected after it reaches 100%, the phone gets warm/hot, the fingerprint doesn't register.
Since then, I got an Anker USB charger which can do fast charging like iPad charger, 2.4A?? charge within 1 - 2 hour (never really check how long it charges, but should be below 2 hours and above 1 hour mark) and unplug before it gets warm.

Avoided charging overnight and no longer using the Apple bundled charging adaptor.

Lousy for me. Finger need 100% dry for the fingerprint scan to work properly. While cheaper phone can perform better. For RM4k phone of course i expect the scanner can tolerate if finger a bit wet. Sometime when i want to use phone quickly out of pocket need to wipe finger 1st
