overheating and purple smudge

okay so i got my s4 I9500 arnd 2 weeks back..
now i have been through the forum nd seen many posts fr overheating issues mainly.
sorry fr posting a new thread..
the main 2 issues i am facing is overheating(main) and purple smudge in contacts(which m nt really concerned of)
The phone is overheated when i play any type of game..be it nfs most wanted..subway surfers..temple run 2..or any normal game..nd while charging also the phone gets very hot..u can touch the screen while charging nd feel the heat..
now my question is that is this a S/W issue or H/W??? what shud i do for this overheating problem...its really very annoying that u pay Rs 40300 for a phone nd it has such type of problems..spending 40300 nd getting such crap?? not worth it..
I really hate samsung for this..first they said octa core which is actually 2 quad cores..then battery life is terrible even though its 2600mAh battery..then such overheating problems...what the hell are samsung charging for??? plastic body?? m really upset with samsung..didnt expect this type of quality nd service frm them.. they are just bloody " SHOW-OFFS"..
nw i dont know what shud i do with this phone.. (

As far as charging "heating" it's because it is charging extremely fast (2mAh charger) so the battery heats up and the screen as well (because of the device's thickness the battery is very close to the screen as well).
As far as gaming overheating, it's because this high end (yes, even subway surfers and temple run 2) games that uses all the A15 cores (even if the game needs only one A15 core). According to AndreiLux, the kernel is designed in a way where only all A7 cores work or all A15 cores work and no any other combination.
He also mentioned that he isn't sure whether it's an h/w or s/w limitation. I think it's a s/w limitation that will get fixed with an update because Samsung already showed (on a tablet) how the core migration works (A15 and A7 working together).
And since this configuration present, also the battery seems not as good as the one Samsung mentioned (the A15 cores consumes much more power than A7 cores).
Don't worry, Samsung knows what their doing

next time before u buy a phone check the specs seriously octa core ?? it's a phone not allien ware
and also check the forum for people's issues
and don't blame samsung for this they just rushed the 4.2.2 that's why and if u don't like it there is always that overpriced iphone for u to buy out there

@Blackwolf10
1)yes its a phone so what,,if samsung is claiming octa core then we shud get octa core..y pay more when only one processor runs at a time..
3)who else shud i blame den, if nt samsung..they r d ones who made this phone..so they r to blame..
i wasnt being rude in anyway..its just that m upset that i paid this much amount nd got a phone which has so many problems..just like other people..

1) Octa means the number of cores there are in the phone, and they are specifically write in their spec sheet that it's 4 A15 and 4 A7 in big.LITTLE architecture. If you didn't do the research, or didn't pay attention to this it's not Samsung's fault.
BTW, still (with "only" 4 cores) this phone outperforms any other phone out there, both in synthetic benchmarks and in actual heavy tasks (such browsing and 3D gaming).
Also, how did you expect from 8 cores to consume less energy if all of them works together?
2) where is it?
3) Blame for what? All your arguments against them are invalid, can be fixed (and will be if you remember the overheating and battery problems last year) or presents in other phones (Overheat in games happens in the S3, HTC one, HTC one X and every other high end smartphone).

Oppo Find 5 Upgraded

The Oppo Find 5 for China has been silently upgraded to the Snapdragon 600 CPU. It has four cores of the upgraded Krait 300 architecture clocked at the higher 1.7GHz and the same Adreno 320 GPU but with 96 ALUs.

I have been contemplating to buy this device for some time now. Once the upgraded version is released internationally I'm definitely procuring one.
Also, how does everyone here like their phone? Worth buying over my current Nexus 4?

I've had a Nexus 4 and my current phone is the Find 5.
The phones are quite similar with the main differences being on the camera and screen front (the Find 5 trumping the Nexus 4 on both fronts). For me, the main differences are as follows:
1. Screen. The Find 5's screen is a lot better than the Nexus 4's. The colours/brightness are so much better plus it's 1080p.
2. Camera. Nexus 4 8MP/Find 5 13MP. Okay, megapixels isn't a good benchmark but still, the oppo find 5's camera is better.
3. Software. The software that comes preloaded on the Find 5 is crap. It's buggy and jerky. Compare that to the Nexus 4 and the 4 wins outright. However, if you root it and flash a custom ROM the experience becomes more comparable. I've tried 3 ROMs so far and the one that I'm currently running (jellybeer) is running really well with no lag whatsoever.
Interesting to hear about the upgraded CPU. Wish I'd have held off now!!! With a 1.7GHz chip I believe the Find 5 will easily trounce the Nexus 4. Also, when comparing against more mainstream flagship devices (S4/HTC One) I prefer to be using an "Indie" phone that is very different than the average person's mobile.
EDIT: link to a comparison of the Nexus 4 and Find 5 - http://www.phonearena.com/phones/compare/OPPO-Find-5,Google-Nexus-4/phones/7600,7531

Being in China, I had a chance to handle the TD version at one of the many Oppo stores here. From what the sales guy said, However, it will only be available in China, as the TD version is being tailored and produced exclusively for use on China Mobile's TD-SCDMA 3G service. You may be able to get it from a grey seller, though, but I wouldn't hold my breath.
The firmwares between the two are also incompatible, so the ROMs you find here won't work on the TD unless someone has modified it.
EDIT: The sales guy from two different stores I went to also said that Oppo isn't producing a 32GB version of the Find 5 TD (one also said the regular Find 5) anymore due to low demand, but take it with a grain of salt, as salepeople here aren't usually experts on their company workings.

Thanks TheMadMan10 and Vapourstreak. I'm a little disappointed to learn that there will not be any international version of the Oppo Find 5 with the Snapdragon 600 CPU. I love the looks and build of the Oppo but now I'm wondering whether it'll be a good idea to buy a phone with relatively older specs. The HTC One and Galaxy S4 theoretically should trounce the Oppo in performance.

Would take the F5 over the N4 every time, although the N4 is really nice being stock Android (I've a Find 5 and wife has Nexus 4). The screen above all makes the F5 a winner, besides anything else for me.
Software-wise, I've tried most stock/beta/Chinese Firefly/custom ROMs and have settled on Chinese open beta Firefly which is really smooth and issue-free with good benchmarks (see sig), although people who who use apps I don't have raised issues.
I suppose if you're wanting absolute top-of-the-line specs and are thinking of the S4 or HTC One, maybe wait for the HTC One Google edition? Personally after two years of Touchwiz and the bland design (subjective) with Note and Note 2 and won't be going back anytime soon.

I personally don't think there's any phone on the market right now that looks better than the Oppo. But that's subjective. The earliest I can get my hands on one is October.
However, I also hear that the Oppo is slower then the Nexus 4 in games as the same Adreno 320 GPU has to power a 5" 1080p screen. What's the opinion of all the Oppo owners here?

Yeah I also read about the Adreno and 1080p - think it was Anandtech review (?)
I'm not a massive gamer but play Real Racing 3 quite a bit and haven't noticed slowdown, only that it's smoother than my old Note 2 - especially when races have 22 cars on track. Haven't tried it on the Nexus 4.
If you're waiting until October then you should have a good idea of what's coming up in terms of new models by then. The F5 will be almost a year old in terms of announcement so maybe an upgrade (Find 7?) is in the works.

Need buying advice - N910C of N910F ?

Which one should I buy if I'm after longer battery life / performance / XDA support?
I'm not a gamer.
Thanks in advance

http://forum.xda-developers.com/note-4/general/to-snapdragon-805-to-exynos-5433-t2868247

Doesn't really matter. The N910F apparently gives better battery life, but some try dispute that. If LTE Cat.6 is implemented in your country then get the N910F as it supports LTE Cat.6. With latest Android 5.1.1 now out for the USA Snapdragons and Exynos Polish, apparently both no longer have Recent Apps lag and they perform much better than before.
Either way youre getting a beastly device.

go for 910c and dont even think about it unless you are cm user.

and why is that? it's simple, both run and will run 32bit, and if you want more processing power, then the C if you want graphics power, then the F.. simple as that, nothing more nothing less..

910f barelys has any more graphics power. not a single game runs better on s805 version(atleast the ones i tried) benchmarks almost same aswell. but on the other hand cpu difference is big. when you use them side by side speed difference is very noticable.
and whatever they are on 32 or 64 bit doesnt mean anything.

I got a N910C, because I never did like Quadcomm SOCs. They tend to run a little hotter than other SOCs. I barely felt any heat of my N910C even when playing Asphalt 8 or Street Fighter IV HD. The only time I felt any heat from my N910C was when it had developed a hardware fault and I had to send it back to the retailer for repairs. Which I'm still waiting for them to finish the repairs.
Other than that I had a great experience with my N910C.

The N910F doesn't run hot, the Snapdragon 805 CPU has to be the coolest of the Qualcomm chips. The only time the phone got hot for me is when upgrading to Lollipop, it got very hot while optimising apps, then calmed down after the update was all done.
As for performance, on 5.1.1 both the C and USA Snapdragons that are basically US N910Fs are running with no Recent Apps lag, so one can't really say there is much of a difference, both run much better than they did on 5.0.1.
Get the variant that has warranty in your country, and if both do, then get the one that best suits your network e.g. if the network supports the newer and faster LTE Cat.6 then get the F, also for slightly better battery life get the F, as well as if you plan on getting the GearVR by Oculus, get the F.
If you want the Exynos CPU and Wolfson DAC, get the C.

I've just sold my 910f and bought the 910c. Two reasons first I just prefer exynos maybe because my last device was exynos. Second the snapdragon does run fairly hot and tended to overheat when using gear vr

Dont do that mistake and buy note 4 it's crap

Exynos 5433 is around ~30% faster at the CPU department, while it has a weaker GPU.
Honestly, it doesn't make much of a difference. But if you can choose, the 910C has better performance.
Weaker GPU matter less than weaker CPU because both are going to run any game exceptionally regardless.
Edit: Exynos 5433 is apparently ~50% ahead of the SD805 at geekbench, difference is bigger than I thought.

Go for C and don't look back.

910C.

I've just got the C & I have noticed it runs smoother than my F & also when I play music via Bluetooth it don't get ant skips, blips etc like i did with the F.
I dunno if it's the 5.1.1 update that has fixed that or its a Snapdragon fault.
So far I'm really happy with the C & just looking at the F & wonder if I should sell it.

The 5.1.1 update seems to have done wonders for both N910F and N910C.

Get the C

Hehehe again a 910C/910F thread, let's see how quickly this one gets closed due to members fighting (cause that's where thread like these are always bound to end up in).
Anyway my personal opinion: if you want to stay stock, then go for the 910C. If you want AOSP then 910F. Yes, CM is currently also available for 910C but they're about 8-12 months behind. Realistically the Note 6 will be out before a 'perfect' stable version will be available for the 910C. These things just take a lot of time to develop.
Quick pro's and cons of stock vs AOSP:
Pro stock:
* Everything just works.
Pro AOSP:
* Quick updates, no need to wait till august 2016 for Android M, you will have it 2 weeks after google releases it
* Blazing fast GUI, everything just works so much smoother.
* Additional features and control over your phone.
Con AOSP:
* Not everything works as of yet, I think currently still missing (although will be worked upon) are AudioFX, MMS, Compass in google maps. And then there's of course the fingerprint scanner but that should be coming with Android M. And then if you flash nightlies every time, you will run into some problems every now and then of course.
Previously camera quality was also a factor but that's solved now, photo quality is now equal.
All in all a personal choice, but I think this is what it boils down to.

Lenovo Vibe P1

The Lenovo Vibe P1 just launched a week ago,
Thinking to buy this device but,
It seems rumor mill has already started churning, about the device facing a "Heating issue".
The device is pretty great for a low ranged smartphone with,
Android v5.1 (Lollipop) OS
4900mAh, Quick Charge
Fingerprint Reader NFC
13 MP PDAF f2.2 Camera
5 MP f2.8 Camera
Dual Sim (LTE + LTE)
5.5 inch FHD 1080p Touchscreen
1.5 GHz Snapdragon 615 64-bit Octa Core Processor
Expandable Storage Capacity of 128 GB
can someone who owns/ knows someone who does/ or expert reviewer , shed some light about this device's issues, especially the heating one? Thanks in advance

I am using one.. Got it yesterday only.. Using it continuously, but No heating issues till now.. But I don't play games and hence ymmv..

Could you test it with some standard games like Clash Of Clans, Asphalt or Modern Combat?
The Heating issue is over hyped on various sites, scared to buy it because of that.

Not Much of a Heater
The phone even after serious gaming for upto 45 mins doesnt go above 44-45 degs (Celcius). Dont worry, I was worried too, saw the gaming review with temp, & then placed the order. I'll be getting mine in a couple of days.

Thanks, was badly worried with the reviews saying the Lenovo Vibe P1 heats upto 50-55 Celsius on long calls and gaming.

how to root this??

Thank

How to root ??
I really want to root this phone
I tried kingroot and iRoot applications
Can anyone suggest a proper way to root this phone ?

Is there a separate FAST CHARGING option for charging?
or it's a separate cable or something?

I am using this phone and the only tim I get this heated up is when it is charging .... but again not more than 45 - 46 .. so this is a good phone and worth the money spent

Fantastic fone for the price. Cost me less than 200 dollars equivilant coupled with an exchange. Good performance. Excellent battery life. Fast charging. Colors and hues not as good as an OPO. Looks quite OK.
5.1.1 out of the box.
Hope developers develop interest in building Custom RoMs, other development support.

unlock bootloader and root for lenovo p1

any rooting method for vibe p1 available?

waiting for someone to port CM12 for pure android experience and overclocking

Problems with my lenovo vibe p1
1st impressions on the phone are good but then later i started to phase some problems like frame drop on ANDROID LOLLIPOP GAME and 2 CARS can not believe this cause a phone with 2gb RAM and octa core 1.5ghz
can not deal with frame drops and one more thing is that when the phone is at low brightness the display starts flickering. ANY SOLUTION FOR THIS?!?!
PLEASE HELP!!! CAUSE I GOTTA REPLACE MY PHONE!!!

The battery life is excellent. After enabling the developer options, there is an option to enable bootloader unlock just like in one plus one. Anyone tried that?

Concerns Exynos vs Snapdragon -UK-

Hi
I just ordered the S20 Plus from EE UK after ordering I noticed Samsung doesn't release the snapdragon chipset in the UK LOL So I had a look online Youtube and noticed they is a clear winner here for the snapdragon also it is 8nm vs 7nm
I do get a 14 day cancellation if I dont like the device.

Both the SD 865 and Exynos 990 are 7nm. It is expected that the Exynos will be behind the SD but we still can't say how much. We have to wait for the first review devices.

Keep in mind. If you ever want to unlock the bootloader that the snap dragon more than likely will not be able to. How it's been for years now. Exynos is the way to go in my opinion.

Both the Exynos and snapdragon chips are good. But in performance Exynos is performing least than the Snapdragon.

So far with my research, the Snapdragon is 20% faster in multi-core operation and 3% behind in Single-core mode.... so some features like AI will be better on the Exynos... but if you play games or render video, the Snapdragon is the clear winner.... My main concern is do I even want to root the phone?!? I lost root on my s8 within the past year and I havent found a need to redo it (since I have the wipe the phone its a PITA)...... I can preorder in the United States right now and trade-in my phone... If I decide to root the phone...I'd want to buy the Exynos verison, which would affect any trade-ins......... Last time I bought the Exynos S8 verison and it has lasted pretty good... I am still using it now however my back in cracked up some and a small crack on the front upper corner that cannot be seen in its case.... So I expect to only get $120 trade in for it.... now, if they will do multiple trade-ins I still have my old S7 as well.... even still... for a S20+ 512gb phone I am looking at $900-$1000 for the phone outright... and then $1300 if i elect to get the Exynos verision if I want to root it eventually...
Decisions Decision... and I am sure most of us in the US are in this situation.... I like the depth sensor so the S20 is out... and the size and weight of the Ultra, plus the fact that I will doubt i will ever use the 108mp mode... the S20+ is big enough coming from the S8.... so only thing left is which CPU?!? I hear the SnapDragon will also be better on Battery life as well... since both chipsets have four ARM Cortex-A55 cores, but where the Snapdragon 865 complements the package with four additional cores based on the ARM Cortex-A77 architecture, the Exynos 990 features two Exynos M5 custom cores and two older ARM Cortex-A76 cores.

Apparently 5G on the Snapdragon version would not work in Europe/UK.
It's all in the other thread for the S20 ultra.
This is very bad - if it's true...

Hey there!
Any further studies comparing SD and exymos proc? Google isn't giving many results atm :-/

I have the UK exynos s20 plus. very disappointed with the camera. Will no doubt return it and consider getting a snapdragon version. at least with that you can use gcam.

https://mightygadget.co.uk/samsung-...mm-snapdragon-865-geekbench-results-compared/
Here is the best comparison so far. Exynos has better GPU (which is rather surprising), and worse CPU department (single core is faster on Exynos and S865 is better in multicore performance). Battery life almost the same. Nothing to complain about Exynos version this year.
---------- Post added at 04:16 PM ---------- Previous post was at 04:14 PM ----------
Here is another comparsion:
https://www.androidcentral.com/galaxy-s20-snapdragon-865-vs-exynos-990
Exynos sometimes literaly destroys S865...

My battery life is doing good enough getting around 4/5 hours screen on time. I have made some adjustments though I run 120hz dark theme on everything I can and also have a dark wallpaper, I dont use Always-on screen and I turned on the adaptive battery and adaptive brightness. I have disabled from running in the background mostly games once I quit them they quit. I use bixby routines for night time so at 12am to 6am my phone is in aeroplane mode and power mode is reduced overnight.
I think that is everything I have done so far

I am not so much concerned about various battery life and power differences as I am about them using completely different camera sensors. comparisons of last few years models has shown clear differences in favour of snapdragon (Sony sensor).

I need dual sim...
Unfortunately I really needed the dual sim so had to go for Exynos variant. Kinda regret it now though. Battery life doesn't seem that great as all the reviews I've seen using the SD chip.

If you.go to settings - device care screen does the battery icon show 'learning usage patterns' underneath the power bar?
If yes then don't try to make any judgement on battery drain until this message disappears

The answer is no, I've been using this phone for 2 weeks. If I'm lucky I will get 4 hours screen on time. I took mine out of 100% charge last night and used 33m. Today so far 1hr 12m. Battery level is already at 60%. Assuming I get another 20mins off and it goes to 50%, that is only 2 hours for 50% of my battery.
It's currently set to 120Hz 1080p, with adaptive power saving and adaptive battery on. Enhanced location with wifi and BT is turned off.
Honestly this is pretty disappointing.

Even if you have the Snapdragon single SIM version, can you still use a MicroSD card then? or....
(currently on the Exynos S20 but I'd like to try the Snapdragon version, just for sh##s and giggles)
