[G4 General] nipun1110:
Let's be clear. G4 is an awesome device. But it's still kindof in the pre-production phage, don't you think? It's not even available 10 countries in the world. Anyway many of who have already bought LG G4, are actually migrated from another smartphone branding either HTC, Samsung, Nexus, Apple etc. And the youtubers contributed a lot in this publicity for LG. I hardly found anyone said any bad thing about G4, neither about it's battery life nor performance in those videos or reviews. But these two have become the most concerning area as well as disappointment for many of the users right now. I, myself also have been suffering with a few issues. I have already changed one device. Coming from XDA forum, here I will try my best to summarize all the problems people are facing with their G4 & also my observation on that matter from my personal experience as well as gathered knowledge from almost all the forums in XDA:

1. MISSED TAP:

Almost all users reporting that G4 missing many taps to recognize.

My observation:

Well, I have also experienced a few missed taps. But what I think it's not a LCD issue, rather less optimization/smoothness issue of the G4 ROM. How do I know? Well I switched on the touch sound. And every tap I did, including the missed ones, there was tapping sound. Even I tested in the manual testing, nothing reported like that. And even after formatting, symptoms reduced for some. But surely it's very annoying.

Oh one thing about knock codes, I found LG LCD doesn't response to gentlest touches sometimes. You need to press slightly a bit more. Fact to be considered : I am still using the provided plastic protector.

2. LAGGING ISSUE:

There is stuttering here and there in G4, not only in the stock launcher but also in the whole system.

My observations:

No doubt G4 lags. You will notice less smoothness / sluggishness while sliding any page up & down in chrome, youtube, Google plus or anything. It is not "butter smooth" like some other OEMs for most of the users. But switching to Nova, turning off smart bulletin & dual window helped to some extent, but not completely.

3. BATTERY LIFE:

Many of the moderate to heavy users complaining about quick battery drainage with low to medium brightness.

My observations:

LG said many things about their battery life of G4 in their announcement party and many well-known youtubers also said very much positive things about G4's battery life i.e. it can easily last a day which raised up the expectation bar of many users. But the real scenario is quite not like that. Most of the medium to heavy users are getting average 3 - 4.5 hours SOT with keeping screen brightness low to medium which is not at all the way LG mentioned. It seems like LG is providing that extra battery knowing the fact that you will need to put on that extra one at the middle of the day for sure. Anyway, what I found is: G4's stand-by time is OUTSTANDING. Don't turn on that screen much, only receive a few calls, you can pass a decade (not literally) with a single charge. But turn on that screen, do browse, chat, Facebooking or Youtubing or anything keeping that overkill screen on, you will hardly pass 5 hours maximum. Raise the brightness a bit more, like 75-100%, brother, you are doomed. Your G4 will die within hours. For some, turning off auto brightness & keeping the brightness below 50% all the time, turning off fast-dormency, turning off GPS, using Greenify helped a bit. Anyway, my point is that awesome-bright-vivid-overkill screen is actually the curse for the G4 at present if LG doesn't bring up some solutions for it. What's the point if you can not enjoy the juice of a fruit which is known to be the tastiest of them all???

4. HEATING & SLOW CHARGING ISSUE:

Very limited people including mine are complaining of frequent, not consistent, heating up issue of the phone as well as slow charging.

My observations:

Many factors can be responsible for this. Some people find this scenario happening once a day, for some once in two days and these two issues are interconnected in my opinion. What can heat up the phone? May be some hidden apps, maybe weather, maybe some other things, but surely it does for some. Yah we have seen in all the reviews that G4 warms up a bit, but not very much. But the people who are complaining about it, found it uncomfortable to speak touching the phone to the face. I will attach a screenshot here, in which my phone was completely idle, was on charge, no phone call came & my phone got heat up to 42 degrees & it took almost 5 hours to charge from 20 - 100%. Again I am saying this is not a consistent scenario, but it's frustrating for some including mine.

5. OTHER ISSUES:

These are some random issues found by some people:

a) White sparking light in the screen.

b) Yellow tint on screen.

c) Bad bluetooth audio.

d) Wifi speed problem.

e) Helium app doesn't work properly.

f) Nova launcher cannot install properly.

g) Vibration too soft.

h) Auto brightness inconsistancy.

So guys, if you have read it and if you are one of those renowned youtubers or columnists or bloggers whom LG guys follow on regular basis, please make an article or video about it, spread these information and let the LG guys know about these so that they can do something about it. I personally believe, software update can solve 95% of the issues. So be it.

Thanks for your patience to read my post.
