I recently broke the screen of my Gigaset GS290.
I looked for a new part on ebay and so on, but it’s unfounadable.
I contacted Gigaset, they gave me the list of official repair offices.
I contacted the french one, they refused to handle my devices because it was not with an official android :-/
So I sent it in Germany, to phone-service Reparatur Ihres Gigaset-Gerät inkl.5€ Erstattung der Einsendekosten : the service … is perfect !
The total cost was 120€, 15€ to send from France to Germany, 90€ for the repair, and 15€ for an over cost to send it back in France. Total delay : 10 days, but 8 for the travels, they repair it in less than 2 days after its reception !

I was able to get it repaired with a bootleg screen from Ali Express.
Find the link below.
This arrived in Spain after only one week for €27 (incl. sending costs). Was able to get it repaired in a local shop for only €25.
New screen is not as colorful as it used to be, and I have to press a tiny bit harder (mind you, these are very minor differences)
All-in-all really happy having my GS290 back, as in the meanwhile I’ve tried flashing a Oneplus 6 and that did not go down well.
