I have no problem with battery after applying the patch, having fully functional Google Services is great, esp. this is an android device.

A spike in the price? Honestly, 1000 is ok, but, with this price? Unless there's some significant upgrade in term of sonic level compare to M11 pro or DX220, this price is.....quite disappointed (regardless how good your "behind stories" are, Fiio)....

It have few short AI voices in English such as: on, off, connected, disconnected... It has blinking blue lights for both sides. I don't have those TWS you mentioned, but as the sound quality, I would give them 6-6.5. If you put it deep into the ears the bass quantity is good, quality is ok, not...

I'm using it, what's your concern? I find it's good for the price. And I don't think I will use any TWS for 5 years, esp. for 20 bucks one.....

Just pull a trigger on a cheap AptX TWS - Tronsmart Spunky Beat, 25 USD is quite a bargain: https://www.aliexpress.com/item/4000196615631.html?spm=a2g0s.9042311.0.0.31824c4d2DrToH

Fiio X5iii is quite good in term of sound, however, it's quite slow due to Android. If you looking for alternative of AP100, I would recommend you to have a look at hiby R3.

AP100 in my opinion is quite bright, if you want a warmer sound signature, you should look elsewhere.

Got my leather case, the upper part is not tight enough, but everything else great.

Maybe it's worth to give a try, my old Fiio DAPs (X5iii and X7ii) have leather cases bundle, both cases were not that bad (at least for me).

I'm also waiting for the leather case ordered from Fiio store on AliExpress. It would be here in next few days . Can't wait.

Well, M11 sound is relaxing, open. It's not super detail (but still good clarity) and slightly loose bass (not as tight as Fiio X7ii). But in general, for the price you have a very relaxing sound profile to enjoy music and very quick, lots of functions DAP. If you only care about the sound, I...

Mainstream combo, good for a relaxing weekend.

These apps are usual Fiio testing app, which normally be in beta firmware. It's quite harmless, you can uninstall them or just leave them there. I have installed beta firmware to upgrade my X7ii to a bigger internal memory partition, an that firmware also have these apps. If your device works...

Apkpure market app stuck downloading this app, I download it from APKPure web instead, please note choosing the ARM8 version.

You mean this app, it works for me (I could open it, but don't have audio book to test it)

Ah, I know a local DIY cable marker, he modded this, not me.

4 core SPC cable, 1m2 length, quite ok.

I have a recable MH755, no more microphonic, and I also have a spare stock MH755, I'm thinking to send it out to have mmcx mod .

Hahaha, I also meant back track button. Using phone for too long.

Old android version usually have such black screen problems that I usually called it "Deep sleep bug", it sleeps, but can't wake up properly. Maybe you could try a hard reset (even a format all data on your microSD card is recommended - especially if that card is used on another android device).

I also have Dev settings active (to turn off annoying slow animation), maybe the firmware? I'm on 1.0.5. Or maybe restart it? Or any software you install interfere with that android function?

Charge M11 with my QC, it charges quite fast, I think it could take maybe 18W (12V 1.5A or 9V 2A, just my guessing on how quick it charged)

I think @cristox mean the voltage is fixed at 5V, 9V, 12V while the Ampere is varied while charging.
