That little indent is actually for a metal plate that goes with their magnet mounting system. It even says what it is for on the case when you get it. Now, sure you can probably use it for wireless charging receivers too, just trying to prevent the spread of misinformation ;)

I had the Nilken wireless receiver that worked great with the Pixel XL, but almost no charging with the XL 2. I too am heavily invested in wireless charging accessories.

I ordered this one today, thanks for doing the research. Fingers crossed that it works good!
[Google Pixel 2 XL Accessories] byproxy:
assuming that if i use magnetic mount for car... i couldn't use one of these adapters right?
[Google Pixel 2 XL Accessories] Sean09:
Can you please advise once you get it? The Nilkin works poorly for me.
[Google Pixel 2 XL Accessories] grinchyyy:
It definitely works better but not by much. I have a TYLT desk charger and I get about 5% per half hour charging rate.
[Google Pixel 2 XL Accessories] blakestimac:
Wow. That's terrible. If that's the best we can expect to get with these receivers, I give up on getting wireless charging on this phone. Luckily, now that Apple added Qi to the iPhone 8, Google basically has to in the upcoming Pixel.
[Google Pixel 2 XL Accessories] ThunderStick:
https://www.amazon.com/Spigen-Google-Wallet-Design-Holder/dp/B07474KKY2

I think using this case paired with a QI receiver would be the best bet right now. You could put a receiver in the wallet section, create a small recess for the ribbon and have a great solution.

Using cases seems to be hit or miss and taping the thing to the back of my $800 phone just aint gonna happen.

Google really biffed on this one, an expensive phone like this should have every feature available plus some. Or at least accessories to add them. I love the pixel, but I love wireless charging too. I missed it ever since my Nexus 5. I have not had a phone with it since, but definitely would like to see it return to a Google Device.
[Google Pixel 2 XL Accessories] jdpeck:
I looked at that one but my concern is the receiver being right against the finish of the phone and if it gets hot would it cause any damage? I've been looking for a case with the TPU then outer shell I can put the receiver between. Have you noticed anything with the finish/coating being damaged?
[Google Pixel 2 XL Accessories] Veritech:
I've taken the case off often for general cleaning or from necessity of needing my USB port for one reason or another and I have not noticed any sort of damage to the phone or case surface at all.

[Google Pixel 2 XL Accessories] GeeWhizRS:
I have that wireless receiver on my pixel 2 XL. It charges up alright but slow by comparison. I have a Satechi inline usb-c power meter and connecting in between the receiver and the phone, it's showing the receiver supplying around 750-800mA. Of course this may vary with the wireless charger, but that's what I'm seeing. I would estimate it charges about 30-40% as fast as a wired charger.

I'm using this with a Spigen Rugged Armour case and find that it made quite a bump on the back. I have sanded some of the inner part of the case away to relieve this with a Dremel and it's an improvement. Why they don't make cases with these cutouts or a removable panel to accommodate a wireless receiver I have no idea.

Actually, I wonder if there was any interest in me machining these cases to order. I could make a fixture to allow me to rout out these cases to accept a wireless charging receiver.
[Google Pixel 2 XL Accessories] Jope31:
Missing my Nexus 6 wireless charging, about to purchase this one for my Pixel 2 XL. How is it doing?
[Google Pixel 2 XL Accessories] grinchyyy:
It does ok, does better with a fast wireless charging base. About 5-10% per hour with my old wireless chargers vs 15-20% per hour with a generic fast wireless charger.

Hi folks. I have a Moto G4 and, as you know, the device will stay on Android 7.0

So... I'm a huge fan of LineageOS, but I wanna know a couple of things before install it.

is the camera in LineageOS the same quality as the stock? and are the Moto Actions like the Moto Display and the hand shaking or the chop twice for flashlight working in this ROM?

I would like to throw a bit of light here. I am the owner of this project for Redmi Pro and somebody asked me in the RMN4 discord group to port it to RMN4 MTK since they are really similar phones, so I also ported it to RMN4 MTK.

I have tried many things in order to solve the remaining bugs but without succeed because I am quite new to ROM developing and it does not look easy since there is only 1 mt6797 with stable Android 7 ROMs AFAIK.

I have found a solution which can fix "Corrupted SD card" bug. Lineage 14.1 (08-22-2017) fixed "SD card" bug in August. So, you can replace fstab.mt6797 (in boot.img) to fix "Corrupted SD card" bug.

[Xiaomi Redmi Note 4 [Mediatek] ROMs, Kernels, Reco] jellybean13:
Thanks. The reason which causes "Corrupted sdcard" problem is that *.fstab (Android 7.x) is different from *.fstab (Android.6.0.x) especially MediaTek device (with MT67XX Soc). Though MediaTek modified storage settings, it caused some bug such as "Total used of" and "used of"...

Then I do recommend you and your team building AOSP ROM because some modified ROMs such as Omni, AOKP, AICP, RR, Lineage and etc modify some setting. Some modifications may cause bugs on MediaTek devices. Next, Vernee leaked MT6797 sources several months ago. You can use Device Tree and Vendor Tree to replace some error files and prebuilt files especially Camera, RIL, WI-FI, VPN, Fingerprint scanner and Media player...

Best wishes.

Edit:

1. Audio can be increased and decreased with no issue.

2. At first I had connection (coverage, no internet connection) but changing the preferred network to LTE I lost all mobile connection. Switching back to the default 3G option made no effect. Registering to an APN didn't change anything, and restoring APN settings to default made no effect.

3. You can't register to Network operator, probably related to the connection issues.

4. System claims to be using 26GB of space, which I doubt it does.

5. The SD card corruption issues [MENTION=8485190]jellybean13[/MENTION] mentions in his previous post
