hi, i have a oneplus 9 256gb version, on the box it says LE2110, but in the menu it says LE2111, so it is a chinese/indian version. But i'm in the uk and after the latest Os13 update my 4g speed is very poor if i have internet at all. i managed to tweak the apn settings to the latest but download speeds are very slow (1-2mbps sometimes upto 5) on my tablet i had 5-14mbps. i only just found out that this is an indian firmware on a chinese phone. so it wasn't the most prudent purchase on ebay . Anyway i wonder if it would be possible to install the Eu firmware and get the eu updates onwards or can it cause further issues? Is the hardware different in any way than the eu versions so could it take the different firmware etc.? if i use this app will my data wiped etc? thanks
Update: Turns out there was a problem with the mast in the area, reported and now seems to be sorted, it wasnt the phone.
