A good experience while my trip in Thailand. I hope that can help some others travelers.

 

My phone (Samsung A3 year 2016) fall in water. The digital screen tactile was out of service. I bring it in the Chiang Mai mall Pantip Plaza (south-East of the city center) in the "191 shop". They fix it in few houra for 1500 baths (around 40 euros). Quick and nice people, I recomand it!

 

NB: the official Samsung shops not sell the Samsung A3 in Thaïlande. So they don't fix it. 

 

Merci.
