Any news about "London" touchscreen issue after update ? Looks like UMI support knows nothing about their own hardware (there are still touch drivers missing in SPFT packs)...

Does anyone fix this problem? A lot of videos on youtube with this problem and no solutions.

Same here, after installing the latest firmware upgrade my touchscreen stopped working properly, it lags and became unresponsive. What are you doing, UMI? We are waiting for the fix of this issue.

Hi Serg1o, did u solved the problem with touch screen on your London? ? I'm in the same situation. Touch screen doesn't work after installation on official update.

Ciao Serg1o, hai risolto il problema con il TP driver del tuo London? Sono nella tua stessa situazione.. sai alla Umi hanno sempre un ottimo tempismo nello spiegare che vi sono differenti versioni del medesimo smartphone.. con diverse caratteristiche e non si sa bene quali siano retrocompatibili con i firmware più recenti.

I think it is TERRIBLE that I have to be a certain level member to be able to post about a BROKEN UMI LONDON - what sort of nonsense is that? Why do you not have a customer service email that we can send our problems too? Anyway, my UMI LONDON turns on and shows the intro logo then after that nothing, the screen is blank. Please help

Я уронил umi london и разбил тачскрин и дисплей. Хочу заменить дисплейный модуль, но проблема в разъёме дисплейного шлейфа. В продаже есть 2 вида модулей с разными шлейфами и одинаковыми разъемами, но они мне не подходят. На моем телефоне дисплейный разъем очень похож на umi diamond x, и я не могу найти такой модуль для london. Я подсоединял к моему телефону дисплейный модуль от diamond x - разъемы шлейфов подошли идеально, но дисплей и сенсор не работали, только мигала подсветка дисплея. Подскажите пожалуйста что мне делать? Может поможет прошивка телефона от diamond x?
