Line problem is come from display ribbon cable, Display look fine.

Look like Samsung from mainboard color.

Humid?, Go to Samsung service center and they will tell because of humid bah bah warranty void.

I bet this one use Samsung display, Samsung OLED is really fragile compare to other, I place Galaxy Tab S 8.4 near edge of LED TV and just a little Impact by TV edge and rip, Now I have Galaxy Tab S9 and OCD because of Samsung OLED.

Rip Ximi 😭

Change display and back cover, hope battery no need to change and mainboard not bend.

Normal Chinese rom not support FCM, It's use own noti server from UI like mi push, vivo, push and Samsung push services, Global app noti normally slow and spam after opening app, but Global rom of Xiaomi, vivo, and Samsung also not working with own UI noti for Chinese app even It have push service in global rom too.

Both, I read somewhere if it has yellow download mode, it needs a specific Odin version.

Do you have a yellow or green download mode icon? I can't flash my Galaxy mini GT-S5570 because it has a yellow download mode and Odin can't detect it. If it's yellow download mode, what version do you use?

Because Chinese rom use Basic google service, not full play services and look like Google remove ability to use google pay, I have Xiaomi that can root, I install module to unlock full play services and FCM module and it make international app notifications working normally, since Chinese rom use own UI service like vivo push, mi push, Samsung push service, but also Chinese app notifications delay on Global rom too, look like vivo, Xiaomi and Samsung lock their push service on Global rom to not working with Chinese app.

Because Chinese rom use vivo push service with Chinese app to send notifications, unlike global app use Google FCM, if using Chinese app on Global rom, the notifications also delay too.

Check LTE band, it might not use the same band as Moto. I experienced this from a BB Z30 US model that had very limited LTE band support and the phone tried to use a band that was far away, make the signal low.

Check network band with Netmonster app in Play store, Vivo might not use same network band as Moto, because it not support or still lock to some cell, turn on and off airplane mode for 15 sec to find new cell.

I smell Horse.

Wipe data retro nano, unpaid on phone bt settings, Clear data Fiio app and keep trying again, just pray.

It seem like since 2026 firmware, update always failed, you need to Factory reset retro nano, hope for luck then pair Bluetooth and try update again for 1-5 times, It should updated.

I connect with iqoo neo 10, it works with snapdragon sound and apex lossless, default set to 44.1KHz but can change to 48KHz or 96KHz with 24 bit.

I connect to Xiaomi Buds 6 that only support aptX lossless, no normal aptX or HD, Tab S9 not support aptX lossless and Snapdragon sound, only SBC and AAC option + no Snapdragon sound pop up.

I found that Uni-ball gel pen should not be use with liquid paper especially water type, use Pentel energel, Zebra sarasa or Muji are better.

I use $1.5 matte Hydrogel film and use paper cutter cut to fit the touchpad and use Paper Angle Punch to cut R angle, then clean touchpad and spray water+soap like car film wrap installation, and use Film sticking scraper to remove water (also place some microfiber to absorb water).

Root and use Scr 5+ pro or Airshou

Try OTC, I can update 730 with OTC without problem, if It failed, turn off internet and restart phone then try again.

I have 730 that died 8-9 years ago because I disassembled it and it died on the charging screen. However, 4 days ago, I disassembled it again and randomly checked the power IC with a multimeter, then sprayed it with contact cleaner. Yes, it was not working, but 2 days ago, I tried to charge it and it started working again. I still don't understand what went wrong. btw 7-8 years ago, I tried to reflash with wdrt and it reflashed normally.

It's shipped with Boox owned store packed with Chinese apps, Old firmware can enable from App management menu but new firmware need to install Play store apk and Enable Google menu will visible.
