IR Working and Process?

I just picked up this phone as I washed my Le Max 2 in the washing machine and immediately bought this phone retail and flashed this ROM. I have no experience phone except with this ROM. So Far So Good!! I knew the Viper ROMs from the HTC phones and stopped flashing phones due to the fact you can just flash a Viper ROM and knew it would be stable and totally customizable.

Anyway, I see that this phone has IR Blaster? Is there a process to get the IR working on Nougat ROMs with this phone? Can someone point me in the right direction if there is?

Thank you to the developers. So far everything is good on Day 1 with this Viper ROM.

There is a lot of battery drain due to android os in my battery stats. Os it normal or I can control it?View attachment 4174612http://cloud.tapatalk.com/s/5938baf0dd054/Screenshot_20170608-081602.png?
[OnePlus 3T Questions & Answers] ExjeetzZ:
First of all, Have you tried using a wake lock detector to find the issue? What ROM are you using including the kernel? Give the full list of all apps installed by you. Are you using root? SuperSu or Magisk? Did you flash a stable version on top of a beta version or vice versa? All i can tell you from the screenshot is that facebook needs to be deleted. No matter how much you enjoy that app, Just login via Chrome and save almost all your 4% you spent on facebook.

What's your idle drain?
[OnePlus 3T Questions & Answers] ProudRed:
I am using BBS after charging my phone to the fullest, I put it in Airplane mode for 6 hours and checked, it drained 2%.

I am using OOS 3.5.4, Kernel is dorimanx. I am attaching the list of apps I use from battery stats.

Yes I am rooted with super su systemless. Yes I have flashed the 2.82 verson. Previously was using magisk but have removed it. View attachment 4174823http://cloud.tapatalk.com/s/59390d762679b/Screenshot_20170608-140942.png?
[OnePlus 3T Questions & Answers] ProudRed:
Anyone with some input ?
[OnePlus 3T Questions & Answers] ExjeetzZ:
Sorry I literally forgot to press send, I'd recommend for you make a back up of everything from within TWRP and copy it on to a computer. I had a lot of issues with older oxygen os but after 4.1.3, I haven't had a issue for a random drain. Do a clean flash and install your apps one by one or use wake lock detector and see which app is misbehaving.
[OnePlus 3T Questions & Answers] luptatorul:
I am having the same kind of issue. I did a super-clean install of stable 4.1.5. This happens in all ROMs for me :-?
[OnePlus 3T Questions & Answers] Batfink33:
This happened on my Nexus 6P also. I think it's a Nougat problem or just the way Nougat calculates drain.
[OnePlus 3T Questions & Answers] luptatorul:
I am having the same issue here. This is on stable 4.1.5. Any ideas?
[OnePlus 3T Questions & Answers] MaxFTW:
Same here unfortunately.

Maybe it's just time to perform a factory reset :rolleyes:
[OnePlus 3T Questions & Answers] matust:
Just started for me as well. Something also seems to be causing the cores to get stuck on Max frequency as well. This never happened on 4.1.3
[OnePlus 3T Questions & Answers] nhshah7:
i've been having the same issue for a couple weeks. I had re-enabled google now and noticed my battery dropped more than i would expect so I've had it disabled for some time now but even with that (which worked before), i've had a lot of consistent drain throughout the day. Battery should last 25-30 hours but it's only lasting me 20-24 due to this consistent drain. I'm thinking I may need a factory reset too, and if that doesn't work, next step is to root and disable "wake up" permissions for all these apps.
[OnePlus 3T Questions & Answers] Krishna Eyunni:
which font BTW ? :silly::silly:
[OnePlus 3T Questions & Answers] OcazPrime:
Well.... People think their phone runs on its own and no it doesn't. Android system is the android environment that manages thinks like drivers internet connectivity logging ram management and basically anything that isn't third party. Your phone's OS cant run without taking power. All your hardware power drain is placed into android system category. There are ways to decrease the consumption but its not very noticeable without xposed and turning some hardware off.
[OnePlus 3T Questions & Answers] ProudRed:
This was Ubuntu.
[OnePlus 3T Questions & Answers] MrMeeseeks:
It should never top your SOT though. Now what is causing it, idk. I had this drain with 4.1.5, but not with any other builds. And I clean flashed twice. And the same set up. That's why I'm on OB8.
[OnePlus 3T Questions & Answers] vikkyvik:
I have noticed this happens a lot while on mobile data. This doesn't happen on WiFi. There's something causing more wake locks when the device is on mobile data! I've tried everything then turning off location history but it doesn't seem to work ☹️
[OnePlus 3T Questions & Answers] OcazPrime:
It can though easily. Especially if you use your device on and off. It doesn't always top my sot but when it does i have less than 3 hours. But then again i never let my battery drain to less than 10%before charging. Just turn things off as you dont use them. Or use IFTTT for that. Try using Better Battery Stats for a few days then check the "ALARMS" section.

Unleashed by ONEPLUS 3T rooted
[OnePlus 3T Questions & Answers] rk2612:
This kind of battery consumption by Android OS is not normal. My experience is that this is caused by some kind of conflict. Such conflicts can be caused by:

* Conflicting apps (...hit and trial to figure out what app caused the conflict)

* Upgrade conflicts (...try to upgrade all apps after system upgrade, clear cache)

* Google services framework conflicts (try to delete cache and data of the app and let it rebuild)

* Customization conflicts (...changes made to /boot or /system ...either manually or by flashing a zip)

If you're able to look up the logs, you should be able to find out the issue (...assuming it is getting logged). If nothing works and as a desperate measure, try to recompile your boot image with androidboot.selinux=permissive in the commandline. This has solved it for me even before I was able to spot the issue causing conflict.

Caution: I'm not an expert myself but came across the solutions referred above while trying to solve my own problem. Try at your own risk and no responsibility of mine.

[ZTE Axon 7 Accessories] EarthboundHero:
Hey guys, I was wondering if there were any good USB-C docks available. It'd be nice if it was compatible with Quick Charge. Thanks for any information!
[ZTE Axon 7 Accessories] grantem2000:
I am very pleased with the FanTEK USB Type-C Smartphone Charging Dock Station which cost me only £8. The Axon 7 sits in it nicely, even when it is in a Spigen Rugged Armor Case. I don't know if this dock is QC compatible, though I doubt it as the USB cable from the dock is quite slim, and there is no mention of QC in the product description on Amazon.
[ZTE Axon 7 Accessories] akeem_da_dream:
added to my wishlist!
[ZTE Axon 7 Accessories] Spillunke:
There are a lot of these docking stations. Same design/product but another brand or seller.

Mine looks the same and its okay. The dock has no weight, so you have to hold the dock down while removing the phone. I wish it would be heavier so i could use only one hand and lift it out.

Also the phone can easy lean to the left or right, because it only stands on the usb port. More stabilisation to the side would be great.

Wouldnt by this again. If nearly all new phones have usb-c, the docking stations will be more and better on the market. actual, there seems no very good one.

i hope my english isnt this bad :/
[ZTE Axon 7 Accessories] beastobadness:
Using one of these... https://www.amazon.co.uk/dp/B017K46T1M/ref=cm_sw_r_sms_apa_jVnCAb6828WWR ...with an Aukey QC3.0 wall charger block and it quick charges fine. Plus it has a height adjustable USB c connector to make it easier to plug in if you are using a chunky case.
[ZTE Axon 7 Accessories] grantem2000:
Your English is good thanks. I agree with your comments: this dock is cheap and does what I need, but anyone buying it should expect to use 2 hands to remove the phone from the dock.
[HTC Desire 510] Sukuoru:
Is it possible to use a Generic Xbox 360 controller (made by PowerA) on this phone? When on my Note 4 in ePSXe the gamepad shows as "(9414:21258)Generic X-Box Pad."

On the Desire, when plugged in with OTG cable the controller number lights just all blink. I kinda want to use this phone as just a little retro machine, it plays gba, ps1 and even psp pretty well. I've been having a lot of fun with it, but when I went to plug in the controller it didn't work. So far I've gotten the custom recovery, rom flashed so it's rooted, and link2sd set up. I also followed a guide that spoke of putting a "Vendor_045e_Product_0291.kl" file into system/usr/keylayout, setting chmod to 644, and restarting but that did nothing.

I'm about to try flashing this kernel, through all my searching this is the only thing that mentions gamepad support. I've backed up everything just now, but wanted to post in case it doesn't work out so I could get ideas from others, if it does then I'll post an update.

(EDIT)

Flashed said kernel, verified it flashed by checking Settings > About Phone, and the controller still doesn't work. Strangely though, the front camera still worked after flash even though that was a reported bug in the kernel. Currently restoring my backup, because everything was perfect as it was and I don't want to deal with anything buggy if that kernel didn't agree with the rom. So, now it's up to you guys. Thanks in advance for any input provided, wouldn't have this phone running so great if it wasn't for everyone here!

Hey, so I got the new Gionee M6S Plus from China and was having problems trying to use Google Play (downloaded by apk). I also downloaded the Google Play Services apk and ran that (if I didn't, Google Play wouldn't even open). But whenever I try to open Google Play, it only shows the white loading screen and seems to "freeze" on the white screen. Also, I keep getting errors messages about "Google Play Services has stopped" messages and was wondering if that was related.
