[LG G5 Questions & Answers] chrcol:
Saying no LAG seems pushing the truth a bit, here is my view of a user who has been using the S5 901f for a couple of years.

What probably has not helped the G5's cause in my case is that samsung made massive performance improvements on their android 6 touchwiz for the S5.

So I have basically been comparing my 901f to the G5 and also to the S7 edge who my brother in law owns and let me have a go with it. Its the more powerful variant of the S7 here in the uk not the snapdragon 820 version.

Also to consider thanks to a good custom kernel my S5 is well tuned, especially with using the zzmoove governor.

So

In terms of overall performance, I would say sadly my S5 beats my G5, the S7 beats them both.

The G5 is very fast at multitasking, so once stuff is loaded, you can switch between apps very quickly and they keep their loaded state, but for stuff not loaded its for some reason slower than both samsung phones.

Some stuff wont stay cached e.g. better battery stats and sms messages, both visibly LAG on my G5 when the simc ard is inserted, I gave the phone to my brother in law to play with, I didnt mention the performance and he commented the phone was laggy. (this was before I did tuning).

Also performance is not everything, when comparing the phone features, samsung wins hands down. The colour tone can be changed, the unique samsung features are actually useful, 2g only mode can be set, has auto redial, better dialer/contacts app.

Samsung has much bigger dev community on XDA, e.g. unless there is a private hidden forum, there is not one single working custom kernel for the G5, that is juat a big wow.

Amoled vs IPS, amoled is a very clear winner, I think what doesnt help the G5 is that its IPS is a poor IPS, my oneplusone phone is also IPS but has less backlight bleed, and better viewing angles than the G5. Amoled is just the pinnacle of flat screen display technology, even apple I think are moving to amoled for their next phones. I only need to look at my G5 slightly off angle and I have contrast shift. I expect overtime I would get used to it, but if you used to samsung displays I think you in for a shock.

Samsung has water resistance, in practice I am not sure its a huge deal, as the LG phone is still splash proof (e.g. it should be fine in the rain).

All this doesnt mean I think the G5 is a bad phone, there is definite stuff about it which is nice.

Has FM radio

Always on clock

Speaker placement is better at bottom

Camera app is better (in my opinion)

USB-C is very nice

Fast charging is nice (although the S7 has this also, but not my S5)

Less bloat on stock rom than samsung.

Much better memory management, especially it doesnt aggressively kill background apps like samsung does.

Faster storage

I hope my feedback is helpful, and of course what I prefer to have on a phone you may not agree with, in which case what I listed as flaws of the G5 may not be relevant to yourself.

Also worth mentioning samsung S7 has 2 spatial streams for wifi so AC is 866mbit, N is 150mbit on 2.4ghz and 300mbit on 5.ghz

LG is 433mbit for AC, 75mbit for N on 2.4 and 150mbit for N on 5

Here in the UK on EE the S7 has a large price premium over the G5 still, over a 2 year contract its an extra �15 month x 24 which is �360.
