Short DYI guide to help you replace broken glass on your G300.
This repair costs about $ 100 in official repair shop, unofficial is about $ 60. It’s far too much for phone that costs about $ 180 (in the Czech Republic).
So I used replacement glass with frame from eBay which costs $ 18.
There are also cheaper glasses on eBay, even ones without Huawei logo, but then you must find some gasket, glue it to the old frame… It’s simpler to replace whole frame. It will also look better. Celý příspěvek
