I installed LineageOS 15.1 on my device, after rebooting into the OS it loads, but the touchscreen doesn't respond, it seems like it registers my touches randomly. The hardware buttons also don't work as expected, when clicking the home button for example a touch is registered in the middle of the screen

Could that be related to the kernel? Is this a known issue? I couldn't find any helpful information Googling this issue.

Help is appreciated
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Uqbar:
Try first to dirty-reflash the ROM and clear the dalvik cache. If this doesn't work, try with a complete wipe and reinstall.

If you still get the problem. then your unit is broken.

There could be a way to troubleshoot with a logcat, but that it's out of my reach.

I am presuming you don't have anything like magisk or xposed. In this case, try to remove the (possibly) offending bit.

I flashed this rom over a locked,pure stock 8.1.10 ROM,steps are simple

1. Unlock your bootloader.

3. Wipe system/data/cache

4. Reboot into bootloader

5. fastboot boot deadman_twrp.img

6. Flash ROM only

7. Reboot into bootloader

8. fastboot boot deadman_twrp.img

9. flash GAPPS and Magisk.

10. Reboot into system.

11. Profit.

touch issues

I've got a weird touch related issue and was wondering if this is a known bug (either software or hardware):

When i'm using most apps touch works as expected, however as soon as i try to play a game there is a huge delay between tapping and the device registering the touch, and in some game related apps only a long touch actually registers as a touch.

I can circumvent this if i don't just tap the screen but tap and then immediately move my finger a bit (kind of like a mini swiping gesture) then the touch is registered normally.

so far i tried the following game related apps and they are all affected: Piano Tiles 2 (touch is registered too late), RetroArch (Touch is only registered when i long press or do the mini swipe), My Boy GBA Emulator (same as retroarch)

Does anyone else experience this or has an idea on how to fix this?

Hi,

has anybody tried the SIP function of the Dialer App? Yesterday I connected my phone with the fritz box and the phone quality was just bad. Incoming voices were delayed and cut. Or would you recommend another client?

Ok, I just switched to Zoiper and no more issues. I guess the standard Android Dialer app isn't ready for SIP yet
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] belidzs:
First of all, thanks to the developers who make LineageOS happen! I have a problem and I don't know if the fault is on my side or it's a bug in the firmware: since I've switched to LineageOS I'm unable to encrypt the phone.

This is how I installed LineageOS: I have formatted the user and the system partition, flashed the OS and the modified gapps from the OP along with Magisk. No other mods were applied. Everything else works as it should (even LDAC which was the main reason to leave stock behind), but I'm unable to enable encryption. When I click on the encryption menu item it checks if the charger is plugged in then asks for confirmation then the screen shows the encryption graphics (green android figure with black background) for a few seconds but then the phone restarts to the system like I've never started the process.

Am I doing something wrong?
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Berlino:
Encryption doesn't work on LOS15.1. You have to flash stock android via MiFlash and get encrypted from there. Then don't FORMAT data - only wipe system, data and dalvik cache and install LOS, gapps and optional root.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] belidzs:
Will try that, thanks!
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Wyroczen:

direct link: https://xdaforums.com/showpost.php?p=77330471&postcount=3850

Sounds interesting, do you know if eXtreme Kernel will still work after this?

When i first set up my A1 i did not format Data to keep the encryption and was not able to boot with eXtreme Kernel only after formating data i was able to boot again.

I'm guessing i'm the only one with this problem then?
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Wyroczen:
I'm not sure about eXtreme kernel, but I have heard that only some of new betas works with encryption enabled. So mostly they don't.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] peterhugelberg:
Right now I'm pretty satisfied with my setup so I'll probably wait till the new version of eXtreme is released and give it a try as I'm making a backup before that anyway
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] belidzs:
Thanks, I can confirm that resizing the user partition in recovery using the guide you've linked fixed the problem, and now my phone is encrypted without losing any data!
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] MadalinC:
Indeed, same story here. After the TWRP resize, everything encrypted just fine via LOS.

However, now each time I install a new app, the OS reboots itself. The installation finishes and the app works, but each time it reboots. Any ideas why?

My device is rooted. Running latest LOS 15.1 from Sept. 25th.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] belidzs:
This didn't happen to me. It might be related to something else, not the encryption
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] MadalinC:
Hmm, Thanks for the heads-up.

I will attempt a clean reinstall of the whole thing and resize the partition before installing LOS and re-enable encryption. Will come back with updates.

EDIT: After a clean format + reinstall, it's now working properly. :)

Hi there,

I'm having trouble getting VoLTE to work on this device. I have two identical MiA1 both with latest lineage. One device has IMS Registration for VoLTE working and the other one has not. I've tried switching two SIMs from Telekom.de and o2-de (Germany) both SIM cards are VoLTE provisioned and I can use VoLTE with both cards on one device. With the other however no VoLTE - both devices have identical good LTE reception. I've tried changing APN, copying APN info from working phone - no success. Both devices show enabled VoLTE provitioning with *#*#4636#*#* but one does no registraion with IMS. With Stock ROM the situation is the same. This leaves me puzzled and with the question if identical MiA1 devices can have different persist/IMS configurations?

Any Idea what I can do/try? Any help is much apprechiated.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] KalolParty:
Am I the only one getting low signal on this ROM?

I just switched from stock to Liquid Remix to Resurrection Remix and they all had fine network.

It is mostly between no bars to 2 bars.

Is this real or just a misrepresentation in the status bar?
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] MKKLR21:
Baseband is the same in both devices?
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] saski4711:
Yes, baseband on both devices is .TA.2.3.c1-00723-8953_GEN_PACK-1

LineageOS version is also the same.

Is it possible that newer devices for the global market have VoLTE disabled in hardware? The older one I have has VoLTE enabled the newer one has not.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] MKKLR21:
Don't think so. What's your preferred network mode in phone information? Try "Global" or "LTE/UMTS (PRL)".

Regarding the baseband version: the string you provided is useless as the version number is cut off. I suggest you should flash the latest firmware and try again.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] saski4711:
Tried all preferred Networks nothing helped :(

Any Idea where I can find the latest modem or extract toe complete modem string? I've extracted the modem.bin from the latest fastboot image OPM1.171019.026.V9.6.5.0.ODHMIFE but no changes. Is there another modem.bin availble?
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] MKKLR21:
Baseband? Here you go: https://xdaforums.com/mi-a1/themes/twrp-baseband-modem-april-stock-rom-t3777901

By the way: do you have an "Enhanced 4G mode" switch in settings? I'm asking, because I'm on stock ROM. I don't have VoLTE either (just tried it out, my A1 is my spare phone). So I suggest, you should try the older basebands one by one.

Addendum: OK, I investigated further. Flashed latest LOS and now my LTE B20 support is gone. In "telephone information" there is an option "Cellular 800" which could mean LTE 800MHz, but my device doesn't connect to LTE. Weird! Tried july baseband, but doesn't work either.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] saski4711:
I'm on LineageOS currently and the Enhanced LTE option is always availble. Also voLTE is provistioned in the *#*#4636#*#* settings. IMS is NOT registered that's the issue I believe. Tried latest August firmware no changes and went back to April modem. No Changes :(

I know of the LTE800 issue. A Friend reported that with his MiA1 after a modem update. I don't want to make you nervous bit he never got Band 20 back even after downgrading modem or switching back to Stock ROM! So if you manage to fix this, plz let me know :)
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] MKKLR21:
I'm back to stock now and LTE is working quite normal. However, no VoLTE available. All switches are grayed out.

In LOS they're available and activated, but no LTE connection possible. Wtf!
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] J0shimi:
Hi folks, I've installed Official LOS via the methods described on the LOS website and realize that AdAway does not work if rooted via LineageOS su add-on.

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] fosiczka:

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] saski4711:
Could you install LTE Discovery or similar tool and see if really Band 20 is used? My friend says after downgrading to Android 7 Stock and upgrading via OTA he has LTE back with o2 Germany. However LTE Discovery shows only LTE Band 3 is used which is odd since o2 does not use Band 3 in his area.

Meanwhile I#m trying to repair my f**ed /persist partition ....
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] MKKLR21:
It definitely is band 20, because I live in a rural area in Germany (in der Pampa ;) ), where all carriers use this frequency.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] heinhuiz:
I've noticed a problem with LOS 15.1 in combination with the Work Profile. When I clone Magisk to the work profile, it is very unstable: sometimes it can't get past the splash screen, other times it start slowly, a few time immediately. Still, other apps can't find it when they are looking for root; for instance with Total Commander I get a time out message.

It must be a bug in the LOS Work Profile, because I experience this with both Island and Shelter. On stock rom, it runs flawlessly.

Note: using latest versions of everything.

Today I travelled around and checked, what band is in use. As LTE Discovery didn't work, I found out that you can read it in test menu. You'll have to set "Mobile info refresh rate" to "Immediate", then you'll see EARFCN value of the cell you are in. 6200 means band 20, 1600 means band 3. At my home location, there's band 20.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] saski4711:
Very useful hint. Thank you! :highfive:
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] rookierks:
Which preferred network type do you have set in the preferences and what does it say about the preferred network type in the test menu?

I have inquired about this before but it seems it's not something many people care or know about, I've tried network signal guru which says it communicates more directly with the baseband chip and it didn't show B20 as selectable/supported, it seemed to show the bands that the Mi5X should support in China, not the bands that the MiA1 should support. There are other people reporting the same issue.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] saski4711:
Well yes and no. It showed clearly that band 20 is availble on my device. Meanwhile I've switched to latest August baseband from stock ROM to fix a VoLTE issue and suddenly band 20 is gone and no more LTE reception. After switching back to latest stock ROM band 20 is still gone no LTE. Damn! Nothing but headeaches when it comes to MIA1 baseband issues :( :crying:
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] rookierks:
This would seem to imply that August's baseband might be somehow connected with the problem. For me not having B20 reception is not a big issue, I can still get lte on other bands but the phone is capable of it and you never know when it can come in handy.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] saski4711:
At least august modem together with LOS introduced the issue for me and cannot be reverted neither with switching to stock or downgrading the modem. Right now I've lost band 20 alltogether :( Strange behaviour....
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] rookierks:
I'm on the same boat as you, I've stopped short of trying the methods to enable extra radio bands on Qualcomm baseband.
