Hello phone gurus,

Please i helped one of my brother to buy Gionee S10 lite UK Used from a seller we met on FB at Ibadan, I sent one of my brother to his physical shop as I am not in Ibadan. So when the phone get to me, I gave it to the owner after I thoroughly checked it... But after like 4-5 hours they guy come back and told me that the phone screen will be blinking anytime it get hot... I saw it also

If it's cool it will display normal... But the moment it's hot.. it will start blinking. I contacted the seller immediately and the seller told me he will contact his suppliers and get back to me... Later the seller now told me he can't collect the phone back coz his suppliers also said he can't collect it back... That probably it fell down or they sit on it, which is not true...

Please how can I go about it and also phone gurus what may be wrong with the phone.

It's only start blinking and be changing to black when its hot
